` and subsections in ``, `` following semantic hierarchy.
+- **Import shared components** with the `@/` alias (e.g., `@/components/common/Button`).
+- **Use existing fonts and colors** — don't introduce new global styles for a single page. Stick to `font-grotesque`, `font-jakarta`, and the dark blue palette (`bg-[#06111f]`, `text-white/70`).
+
+---
+
+## Part 2: Route Registration
+
+Routes are registered in a **single source of truth** at `src/routes.tsx`. Add your new page there:
+
+```tsx
+// src/routes.tsx
+import HomePage from './pages/HomePage';
+import CreatorDetailPage from './pages/CreatorDetailPage';
+import YourNewPage from './pages/YourNewPage'; // ← import your page
+
+export const routes = [
+ {
+ path: '/',
+ element: {/* render your page with data */} ;
+}
+```
+
+### Query Key Factory Pattern
+
+All React Query keys are defined in a **single central factory** at `src/lib/queryKeys.ts`. This keeps key shapes predictable and invalidation reliable.
+
+**Key structure:**
+
+```ts
+export const queryKeys = {
+ yourEntity: {
+ all: ['yourEntity'] as const,
+ list: (params?: GetYourParams) =>
+ ['yourEntity', 'list', params ?? null] as const,
+ detail: (id: string) => ['yourEntity', 'detail', id] as const,
+ holders: (entityId: string) =>
+ ['yourEntity', entityId, 'holders'] as const,
+ },
+};
+```
+
+**Key rules:**
+
+1. **`all` key** — every entity group has a static `all` key for bulk invalidation.
+2. **Shared prefixes** — all keys in a group start with the same entity name so prefix-based invalidation works.
+3. **`as const`** — return `as const` tuples so TypeScript infers literal types.
+4. **Optional params become `null`** — when a list query has no filters, store `null` at the param position for consistent key shape.
+
+**Add your entity to the factory:**
+
+```ts
+// src/lib/queryKeys.ts (existing)
+
+import type { GetYourParams } from '@/services/your.service';
+
+export const queryKeys = {
+ creators: {
+ /* ... */
+ },
+ wallet: {
+ /* ... */
+ },
+ yourEntity: {
+ all: ['yourEntity'] as const,
+ list: (params?: GetYourParams) =>
+ ['yourEntity', 'list', params ?? null] as const,
+ detail: (id: string) => ['yourEntity', 'detail', id] as const,
+ },
+};
+```
+
+See [docs/react-query-cache-conventions.md](./react-query-cache-conventions.md) for full details on cache invalidation patterns.
+
+### Loading and Error States
+
+Always handle the three states: `isLoading`, `error`, and `data`:
+
+```tsx
+import { CreatorProfileHeaderSkeleton } from '@/components/common/CreatorSkeleton';
+import { ApiError } from '@/services/api.service';
+
+export default function YourDetailPage() {
+ const { id } = useParams<{ id: string }>();
+ const { data, isLoading, error } = useYourData(id || '');
+
+ // 1. LOADING: Show a skeleton while fetching
+ if (isLoading) {
+ return (
+
+
+ );
+ }
+
+ // 2. ERROR: Throw to error boundary or render error UI
+ if (error) {
+ throw error; // handled by error boundary (see Part 5)
+ }
+
+ // 3. NO DATA: Throw a 404 error
+ if (!data) {
+ throw new ApiError('Not found', 404);
+ }
+
+ // 4. SUCCESS: Render your page
+ return (
+
+ {data.title}
+ {/* render data */}
+
+ );
+}
+```
+
+### Stale Time Configuration
+
+React Query data is stale immediately by default (`staleTime: 0`). Override this for data that changes infrequently:
+
+```ts
+useQuery({
+ queryKey: queryKeys.yourEntity.detail(id),
+ queryFn: () => yourService.fetchData(id),
+ staleTime: 30_000, // data is fresh for 30 seconds
+});
+```
+
+| Data Type | Recommended staleTime | Rationale |
+| -------------------------------- | --------------------- | ------------------------------ |
+| Real-time (prices, balances) | `0` (default) | Always show the latest value |
+| Semi-static (profiles, metadata) | `30_000` – `60_000` | Balance freshness vs refetches |
+| Rarely-changing (lists, config) | `5 * 60_000` (5 min) | Reduce bandwidth |
+| Truly static | `Infinity` | Fetch once per session |
+
+See [docs/react-query-cache-conventions.md](./react-query-cache-conventions.md#stale-time-and-cache-time) for full details.
+
+---
+
+## Part 4: Service Layer and Data Types
+
+Data fetching happens through a **service layer** in `src/services/`. Each service is a class that extends `BaseApiService` and handles a domain (creators, wallet, etc.).
+
+**Example:**
+
+```ts
+// src/services/your.service.ts
+import { BaseApiService, type APIResponse } from './api.service';
+
+export interface YourEntity {
+ id: string;
+ title: string;
+ description: string;
+ // ... other fields
+}
+
+class YourService extends BaseApiService {
+ async getYourData(id: string): Promise {
+ try {
+ const response = await this.api.get>(
+ `/your-endpoint/${id}`
+ );
+ return response.data.data;
+ } catch (error) {
+ throw this.handleError(error);
+ }
+ }
+}
+
+export const yourService = new YourService();
+```
+
+Then import and use it in your hook:
+
+```ts
+// src/hooks/useYourData.ts
+import { yourService } from '@/services/your.service';
+
+export function useYourData(id: string) {
+ return useQuery({
+ queryKey: queryKeys.yourEntity.detail(id),
+ queryFn: () => yourService.getYourData(id),
+ enabled: !!id,
+ });
+}
+```
+
+See [docs/api-layer.md](./api-layer.md) for full service layer conventions.
+
+---
+
+## Part 5: Layout Components and Error Boundaries
+
+### When to Use Shared Layouts
+
+Check `src/components/common/` for existing layout and wrapper components:
+
+- **`CreatorPageErrorBoundary`** — wraps creator pages to catch and handle errors
+- **`SectionErrorBoundary`** — wraps individual sections to handle errors in one area without crashing the whole page
+- **`SectionHeading`** — formats section titles consistently
+- **`CardMetaRow`** — displays metadata in a consistent card row style
+
+Use these when they fit. Don't create a new layout component unless an existing one truly doesn't match your needs.
+
+### Error Boundaries for Pages
+
+Wrap your page content in an error boundary to catch and display errors gracefully:
+
+```tsx
+// src/pages/YourDetailPage.tsx
+import YourPageErrorBoundary from '@/components/common/YourPageErrorBoundary';
+
+function YourDetailPageContent() {
+ // ... your page logic with data fetching
+ return {/* content */} ;
+}
+
+export default function YourDetailPage() {
+ return (
+
+
+ );
+}
+```
+
+If a similar error boundary exists (e.g., `CreatorPageErrorBoundary`), study it and reuse or adapt it. Create a new one only if your error handling is significantly different.
+
+---
+
+## Part 6: Complete Minimal Example
+
+Here's a full example adding a new page called `/creators` that lists all creators:
+
+### Step 1: Create the Page
+
+```tsx
+// src/pages/CreatorListPage.tsx
+import { useCreatorList } from '@/hooks/useCreatorList';
+import CreatorCard from '@/components/common/CreatorCard';
+import { CreatorCardGridSkeleton } from '@/components/common/CreatorCardSkeleton';
+import { ApiError } from '@/services/api.service';
+
+function CreatorListPageContent() {
+ const { data: creators, isLoading, error } = useCreatorList();
+
+ if (isLoading) {
+ return (
+
+
+ );
+ }
+
+ if (error) {
+ throw error;
+ }
+
+ if (!creators || creators.length === 0) {
+ throw new ApiError('No creators found', 404);
+ }
+
+ return (
+
+
+ All Creators
+
+
+ {creators.map(creator => (
+
+ );
+}
+
+export default function CreatorListPage() {
+ return Page'` path shown above, matching the existing imports.
+- **Do not** create a second router or wrap the app in another `Page` | `export default function AboutPage()` |
+
+The component itself uses `export default function Page()` — not a named export, and not an arrow const. This keeps imports straightforward and matches every existing page in `src/pages/`:
+
+```
+src/pages/
+├── HomePage.tsx // registered as '/'
+├── MarketingPage.tsx // exists on disk, not yet registered
+├── LandingPage.tsx // exists on disk, not yet registered
+└── NotFoundPage.tsx // registered as '*' (catch-all)
+```
+
+A few pages exist as files but are not currently wired into the router in `src/App.tsx`. They are kept on disk because they are planned routes waiting on the marketplace flows to land. If you need one of them live, follow this guide to register it like any other page.
+
+### What a page component looks like
+
+Top-level page components take **no props**. They own their own layout, fetching, and state. A minimal page is just a function that returns JSX:
+
+```tsx
+// src/pages/AboutPage.tsx
+export default function AboutPage() {
+ return (
+
+
+ About Access Layer
+
+
+ Access Layer is a Stellar-native creator keys marketplace.
+
+
+ );
+}
+```
+
+Conventions to follow:
+
+- **Default export only.** Named exports break the import in `App.tsx`.
+- **One component per file.** Don't lump multiple pages into a single file.
+- **No props.** Reach for URL params via `useParams()` from `react-router` instead of prop drilling.
+- **Accessibility:** wrap content in a single `` landmark and use semantic headings (`` for the page title).
+- **Match the project styling.** Use the existing `font-grotesque`, `font-jakarta`, and dark-on-blue palette referenced throughout the codebase. Don't introduce new global styles for a single page.
+- **Use the `@/` alias for component imports.** The project-wide path alias `@/` maps to `src/` (configured via Vite + TypeScript path mapping). Use it freely from any component file; reserve short relative paths like `'../pages/Page'` for tight sibling-file imports.
+
+---
+
+## Public vs auth-protected routes
+
+There is **no existing `RequireAuth` / `ProtectedRoute` wrapper** in the codebase yet. Every route registered today is public. When a feature needs auth gating, follow the pattern below — and ship the wrapper component with that feature, since the client doesn't have a standalone auth-guard component yet.
+
+### Recommended pattern
+
+1. Create a small wrapper component, conventionally `src/components/auth/RequireAuth.tsx` (create the `auth/` subfolder if it doesn't exist yet).
+2. Inside the wrapper, check the appropriate auth state — wagmi's `useAccount` for wallet-gated flows, or `authService.isAuthenticated()` for email/login-gated flows.
+3. While the state is resolving, render a lightweight placeholder (the existing `PendingOnboardingPlaceholder` makes a good model).
+4. If unauthenticated, render a redirect or a connect-wallet CTA — do **not** render the protected page.
+5. Wrap the protected page's `element` with the wrapper inside `App.tsx`.
+
+```tsx
+// src/components/auth/RequireAuth.tsx
+import type { ReactNode } from 'react';
+import { useAccount } from 'wagmi';
+import { Navigate, useLocation } from 'react-router';
+import PendingOnboardingPlaceholder from '@/components/common/PendingOnboardingPlaceholder';
+
+interface RequireAuthProps {
+ children: ReactNode;
+}
+
+export default function RequireAuth({ children }: RequireAuthProps) {
+ const { isConnected, isConnecting } = useAccount();
+ const location = useLocation();
+
+ // Show the placeholder while a fresh wallet connection is in flight
+ // so the user isn't redirected to "/" mid-connect. Once it resolves,
+ // isConnected flips to true and we render the protected page below.
+ // Note: isReconnecting is intentionally NOT in this branch — a
+ // reconnect of a prior session keeps the user authenticated, so
+ // rendering the protected page during a reconnect is fine.
+ if (isConnecting) {
+ return :
+ element: (
+
+
+ ),
+ },
+ { path: '*', element: ` is not currently mounted above ``. Any wagmi hook — including `useAccount` inside `RequireAuth` — will throw at runtime because the `WagmiProvider` context is missing. Wiring `` here is an app-level change and should be tracked separately; reference the tracking issue in your route PR description rather than embedding the wiring fix in your route PR.
+2. **Wagmi has a transient `isConnecting` state** while a fresh wallet handshake is in flight. During this window `isConnected` is `false`, but redirecting the user mid-connect would bounce them away. The example above handles this by rendering `PendingOnboardingPlaceholder` for the `isConnecting` branch — copy that pattern verbatim. (Note: `isReconnecting` is _not_ included in that branch — a reconnect of a prior, already-authenticated session keeps the user authenticated, so rendering the protected page during a reconnect is fine and avoids a UX flash.)
+
+If your guard only uses `authService.isAuthenticated()` (no wagmi hooks), neither caveat applies — the helper reads `localStorage` directly.
+
+---
+
+## Worked example — adding a new public page
+
+This walks a contributor end-to-end through adding `AboutPage` at `/about`. The page is public, so no `RequireAuth` wrapper is involved.
+
+### 1. Create the page component
+
+Add a new file at `src/pages/AboutPage.tsx`:
+
+```tsx
+// src/pages/AboutPage.tsx
+import { Link } from 'react-router';
+import { Button } from '@/components/ui/button';
+
+export default function AboutPage() {
+ return (
+
+
+ About Access Layer
+
+
+ Access Layer is a Stellar-native creator keys marketplace built on
+ the open AccessLayer protocol.
+
+
+
+
+
+
+ );
+}
+```
+
+### 2. Register the route
+
+Add the import and a new entry to the router array in `src/App.tsx`:
+
+```tsx
+// src/App.tsx
+import HomePage from './pages/HomePage';
+import NotFoundPage from './pages/NotFoundPage';
+import AboutPage from './pages/AboutPage'; // ← added
+
+const router = createBrowserRouter([
+ { path: '/', element: .service.ts` | `wallet.service.ts` |
+| Class name | `Service` | `WalletService` |
+| Exported singleton | `Service` | `walletService` |
+
+Every service class **extends `BaseApiService`** from `api.service.ts`, which provides:
+
+- A pre-configured Axios instance (`this.api`) pointing at `VITE_BACKEND_URL`
+- Automatic token refresh on `401 TOKEN_EXPIRED` responses
+- A shared `handleError(error)` method that normalises any thrown value to `ApiError`
+
+---
+
+## Error handling
+
+Every service method wraps its Axios call in a `try/catch` and re-throws via `this.handleError`:
+
+```ts
+async getWalletHoldings(address: string): Promise {
+ try {
+ const response = await this.api.get>(
+ `/wallets/${address}/holdings`
+ );
+ return response.data.data;
+ } catch (error) {
+ throw this.handleError(error);
+ }
+}
+```
+
+`handleError` always returns an `ApiError` instance with:
+
+| Field | Type | Description |
+| ---------- | ------------------------------- | ------------------------------------------ |
+| `message` | `string` | Human-readable error message |
+| `status` | `number` | HTTP status code; `0` for network failures |
+| `response` | `APIErrorResponse \| undefined` | Full server error payload when available |
+
+Callers can check `error instanceof ApiError` and inspect `error.status` for branching logic.
+
+---
+
+## How to add a new endpoint
+
+### 1. Add the method to the relevant service file
+
+Open `src/services/.service.ts` (or create a new one if the domain is new). Add a method that:
+
+1. Calls `this.api.get/post/patch/delete`
+2. Extracts `response.data.data`
+3. Re-throws any error via `this.handleError`
+
+```ts
+// src/services/wallet.service.ts
+import { BaseApiService, type APIResponse } from './api.service';
+
+export interface Holding {
+ creatorId: string;
+ quantity: number;
+ priceStroops: number;
+}
+
+class WalletService extends BaseApiService {
+ async getHoldings(address: string): Promise {
+ try {
+ const response = await this.api.get>(
+ `/wallets/${address}/holdings`
+ );
+ return response.data.data;
+ } catch (error) {
+ throw this.handleError(error);
+ }
+ }
+}
+
+export const walletService = new WalletService();
+```
+
+### 2. Define a query key in `src/lib/queryKeys.ts`
+
+Add an entry for the new endpoint so all hooks that reference the same data use an identical cache key:
+
+```ts
+// src/lib/queryKeys.ts
+wallet: {
+ holdings: (address: string) => ['wallet', address, 'holdings'] as const,
+ // ...
+},
+```
+
+### 3. Write a React Query hook
+
+`QueryClientProvider` is already wired up in `src/providers/Web3Provider.tsx` — no setup changes needed.
+
+```ts
+// src/hooks/useWalletHoldings.ts
+import { useQuery } from '@tanstack/react-query';
+import { walletService } from '@/services/wallet.service';
+import { queryKeys } from '@/lib/queryKeys';
+
+export function useWalletHoldings(address: string | undefined) {
+ return useQuery({
+ queryKey: queryKeys.wallet.holdings(address ?? ''),
+ queryFn: () => walletService.getHoldings(address!),
+ enabled: Boolean(address),
+ });
+}
+```
+
+### 4. Consume the hook in a component
+
+```tsx
+import { useWalletHoldings } from '@/hooks/useWalletHoldings';
+
+function HoldingsList({ address }: { address: string }) {
+ const { data: holdings, isLoading, error } = useWalletHoldings(address);
+
+ if (isLoading) return Loading…
;
+ if (error) return Failed to load holdings.
;
+
+ return (
+
+ {holdings?.map(h => (
+ -
+ {h.creatorId} — {h.quantity} keys
+
+ ))}
+
+ );
+}
+```
+
+---
+
+## Worked example — full GET call
+
+The following shows a complete end-to-end flow for a `GET /wallets/:address/holdings` endpoint.
+
+### Service method
+
+```ts
+// src/services/wallet.service.ts
+import { BaseApiService, type APIResponse } from './api.service';
+
+export interface Holding {
+ creatorId: string;
+ quantity: number;
+ priceStroops: number;
+}
+
+class WalletService extends BaseApiService {
+ async getHoldings(address: string): Promise {
+ try {
+ const response = await this.api.get>(
+ `/wallets/${address}/holdings`
+ );
+ return response.data.data;
+ } catch (error) {
+ throw this.handleError(error);
+ }
+ }
+}
+
+export const walletService = new WalletService();
+```
+
+### Query key
+
+```ts
+// src/lib/queryKeys.ts (existing file — add the entry)
+wallet: {
+ holdings: (address: string) => ['wallet', address, 'holdings'] as const,
+},
+```
+
+### Hook
+
+```ts
+// src/hooks/useWalletHoldings.ts
+import { useQuery } from '@tanstack/react-query';
+import { walletService } from '@/services/wallet.service';
+import { queryKeys } from '@/lib/queryKeys';
+
+export function useWalletHoldings(address: string | undefined) {
+ return useQuery({
+ queryKey: queryKeys.wallet.holdings(address ?? ''),
+ queryFn: () => walletService.getHoldings(address!),
+ enabled: Boolean(address),
+ });
+}
+```
+
+### Component
+
+```tsx
+// Usage in any component
+import { useAccount } from 'wagmi';
+import { useWalletHoldings } from '@/hooks/useWalletHoldings';
+
+function HoldingsSummary() {
+ const { address } = useAccount();
+ const { data: holdings, isLoading, error } = useWalletHoldings(address);
+
+ if (isLoading) return Loading…
;
+ if (error) return Could not load holdings.
;
+ if (!holdings?.length) return No holdings yet.
;
+
+ return (
+
+ {holdings.map(h => (
+ -
+ {h.creatorId} — {h.quantity} keys at {h.priceStroops} stroops
+
+ ))}
+
+ );
+}
+```

+# Environment Variable Guide
+
+This guide explains how to add a new client environment variable safely and consistently in Access Layer Client.
+
+The client is built with Vite, so any value that must be available in browser code must use the `VITE_` prefix. Values without that prefix are not exposed to the client bundle.
+
+## Files involved
+
+| File | Purpose |
+| ------------------------ | ---------------------------------------------------------------------------------------------------------------- |
+| `.env.example` | Documents every supported variable and provides safe local defaults or blank optional placeholders. |
+| `src/utils/env.utils.ts` | Validates environment variables at startup with Zod and exports the typed `env` object used by application code. |
+| `.env` | Local developer overrides. This file should not be committed. |
+
+## Add a new variable
+
+1. Add the variable to `.env.example`.
+2. Add validation for the variable in `src/utils/env.utils.ts`.
+3. Pass the raw `import.meta.env` value into the `envSchema.parse(...)` call in `src/utils/env.utils.ts`.
+4. Import the validated `env` object in application code.
+5. Avoid reading `import.meta.env` directly from components, hooks, or service files.
+
+## Declaration pattern
+
+Add the new variable to `.env.example` near related settings. Use a short comment that explains what the value controls and whether it is required.
+
+```env
+# Feature flag for the creator discovery experiment. Use `true` to enable locally.
+VITE_ENABLE_CREATOR_DISCOVERY=false
+```
+
+Prefer safe development defaults when the app can run without secrets. Leave optional third-party keys blank if a contributor can work without them.
+
+## Runtime validation pattern
+
+All supported variables should be declared in `src/utils/env.utils.ts` so missing or malformed configuration is caught in one place.
+
+```ts
+const envSchema = z.object({
+ VITE_ENABLE_CREATOR_DISCOVERY: z.coerce.boolean().default(false),
+});
+
+export const env = envSchema.parse({
+ VITE_ENABLE_CREATOR_DISCOVERY: import.meta.env.VITE_ENABLE_CREATOR_DISCOVERY,
+});
+```
+
+Use the Zod type that matches how the app consumes the value:
+
+| Value type | Validation example |
+| --------------- | ----------------------------------------------- |
+| Required string | `z.string().min(1, "VITE_API_KEY is required")` |
+| Optional string | `z.string().optional()` |
+| Number | `z.coerce.number().default(84532)` |
+| Boolean flag | `z.coerce.boolean().default(false)` |
+
+If a value is required for the app to start, avoid a silent fallback. Use `.min(1, "... is required")` or another explicit validation rule so the startup error points to the missing variable.
+
+## Access pattern in application code
+
+Import `env` from the validation module and read the typed value from there:
+
+```ts
+import { env } from '@/utils/env.utils';
+
+if (env.VITE_ENABLE_CREATOR_DISCOVERY) {
+ // Render or enable the feature.
+}
+```
+
+This keeps validation, defaults, and type coercion centralized.
+
+## Anti-pattern: direct component access
+
+Do not import or read `import.meta.env` directly in components, hooks, services, or utilities outside the validation module.
+
+```tsx
+// Avoid this.
+const backendUrl = import.meta.env.VITE_BACKEND_URL;
+```
+
+Direct access bypasses schema validation, makes defaults inconsistent, and spreads environment knowledge across the app. Use `env` instead:
+
+```tsx
+import { env } from '@/utils/env.utils';
+
+const backendUrl = env.VITE_BACKEND_URL;
+```
+
+## Required vs optional checklist
+
+Use this checklist before opening a PR that adds a new variable:
+
+- The variable is listed in `.env.example`.
+- The variable has a clear comment describing its purpose.
+- Required values fail fast in `src/utils/env.utils.ts` with a useful error.
+- Optional values use `.optional()` or a safe `.default(...)`.
+- Application code reads from `env`, not `import.meta.env`.
+- The variable name starts with `VITE_` if browser code needs it.

+## Decision Flowchart
+
+Walk this top to bottom. The first matching branch wins.

+
+## Mode 1 — Toasts for Mutation Errors
+
+**Use when:**
+
+- The failure came from a user-initiated write (buy, sell, course enroll,
+ profile update, share, copy).
+- The page can still render usefully without retrying.
+- One short line of feedback is enough — the user needs to know "this
+ didn't work" and either retry or change input.
+
+**Don't use when:**
+
+- The failure blocks the primary purpose of the screen (use Mode 2).
+- The failure contains field-level validation detail that must attach to a
+ specific input (use Mode 2 inline errors with `apiError.response?.errors`).
+- You need to retry automatically — toasts disappear, they don't retry.
+
+### Pattern: `useMutation.onError`
+
+Cast the error to `ApiError` and branch on `status`. The numeric scale is
+documented in
+[Error Handling in Hooks → Distinguishing Error Types](./error-handling-in-hooks.md#distinguishing-error-types);
+here is the consolidated decision:
+
+```ts
+// src/hooks/useBuyCreatorKey.ts
+import { useMutation, useQueryClient } from '@tanstack/react-query';
+import { ApiError } from '@/services/api.service';
+import showToast from '@/utils/toast.util';
+import { queryKeys } from '@/lib/queryKeys';
+import { creatorKeysService } from '@/services/creatorKeys.service';
+
+export function useBuyCreatorKey() {
+ const queryClient = useQueryClient();
+
+ return useMutation({
+ mutationFn: ({
+ creatorId,
+ amount,
+ }: {
+ creatorId: string;
+ amount: number;
+ }) => creatorKeysService.buyKey(creatorId, amount),
+
+ onError: error => {
+ const apiError = error as ApiError;
+
+ // 1. Network failure — user is offline / server unreachable
+ if (apiError.status === 0) {
+ showToast.error(
+ 'Network error. Check your connection and try again.'
+ );
+ return;
+ }
+
+ // 2. Server failure — not the user's fault; generic + retry
+ if (apiError.status >= 500) {
+ showToast.error(
+ 'The server ran into a problem. Please try again shortly.'
+ );
+ return;
+ }
+
+ // 3. Validation — surface the first field error if present
+ if (apiError.status === 422 && apiError.response?.errors?.length) {
+ showToast.error(apiError.response.errors[0].message);
+ return;
+ }
+
+ // 4. Other 4xx — API message is safe for the user
+ showToast.error(apiError.message);
+ },
+
+ onSuccess: (_, { creatorId }) => {
+ queryClient.invalidateQueries({
+ queryKey: queryKeys.creators.detail(creatorId),
+ });
+ queryClient.invalidateQueries({ queryKey: queryKeys.wallet.all });
+ showToast.success('Key purchased successfully!');
+ },
+ });
+}
+```
+
+### Pattern: User rejection (wallet signature)
+
+Wallet signatures can be rejected by the user mid-flow. Detect this with
+the shared helper and skip the noisy generic toast:
+
+```ts
+// src/hooks/useWalletConnection.ts (excerpt)
+import { getSignatureErrorMessage } from '@/utils/errorHandling.utils';
+import showToast from '@/utils/toast.util';
+
+onError: error => {
+ showToast.error(getSignatureErrorMessage(error));
+ // getSignatureErrorMessage returns either:
+ // - WALLET_ERROR_COPY.SIGNATURE_REJECTED (user clicked "Cancel")
+ // - WALLET_ERROR_COPY.SIGNATURE_FAILED (other wallet-side failure)
+};
+```
+
+`getSignatureErrorMessage` is implemented in
+[`src/utils/errorHandling.utils.ts`](./../src/utils/errorHandling.utils.ts)
+and detects the EIP-1193 code `4001`, ethers' `ACTION_REJECTED`, and the
+common message fragments "user rejected" / "declined" / "cancelled".
+
+### Pattern: Off-chain mutation that should NOT use a drawer
+
+Copy-to-clipboard, share-to-Twitter, follow a creator — all of these are
+writes that have no chain side effects. Just toast:
+
+```ts
+// Excerpt from CreatorProfileHeader
+const handleShare = async () => {
+ try {
+ await navigator.clipboard.writeText(profileUrl);
+ showToast.success('Profile link copied to clipboard!');
+ } catch {
+ showToast.error('Could not copy the profile link. Please try again.');
+ }
+};
+```
+
+---
+
+## Mode 2 — Inline Error State for Blocking Query Failures
+
+**Use when:**
+
+- The query is the primary content of the page (e.g. creator profile header).
+- Without the data, the screen is empty; there is nothing else for the user
+ to do here.
+- You want the user to retry without leaving the page — wire `refetch` from
+ React Query.
+
+**Don't use when:**
+
+- The query is enriching a page that can render something else (use Mode 3).
+- The failure came from a mutation (use Mode 1).
+
+### Pattern: Canonical shared component
+
+`CreatorProfileErrorState` is the canonical inline error component. It
+renders a marketplace-styled card with an icon, a message, and an optional
+retry button.
+
+```tsx
+// In a creator profile section
+import { useCreatorProfile } from '@/hooks/useCreatorProfile';
+import CreatorProfileErrorState from '@/components/common/CreatorProfileErrorState';
+import { ApiError } from '@/services/api.service';
+
+function CreatorHeader({ creatorId }: { creatorId: string }) {
+ const { data, isLoading, isError, error, refetch } =
+ useCreatorProfile(creatorId);
+
+ if (isLoading) return void refetch()}
+ isRetrying={
+ false /* wire from your query's isFetching if you want */
+ }
+ title="Unable to load this creator profile"
+ />
+ );
+ }
+
+ return
+ {apiError.status >= 500
+ ? 'Unable to load holdings. Please try again later.'
+ : apiError.message}
+
+
+
+ );
+}
+```
+
+### Inline vs. throw-to-boundary — the rule
+
+> If the failure should leave the rest of the page interactive → render an
+> **inline** state. If it means the route as a whole cannot be useful → throw
+> the error and let the page-level boundary catch it.
+
+Concretely:
+
+- A creator list failing inside the marketplace page? **Inline.** The hero,
+ filters, and holdings are still useful.
+- The creator profile header failing on `/creator/:id`? **Throw** →
+ `CreatorPageErrorBoundary` renders a "Creator not found" or
+ "could not load" page-level state and a back-link.
+
+---
+
+## Mode 3 — Section Error Boundary (Render Falls Here)
+
+**Use when:**
+
+- A sub-component (tab body, sidebar, list section) can throw during render
+ — e.g. it consumes data that is undefined when the parent didn't gate it.
+- A failure in **this section** should not crash the whole page.
+- The user should be able to retry the section without a full reload.
+
+**Don't use when:**
+
+- The error is a query failure (React Query surfaces it via `isError` —
+ branch in the component, don't throw).
+- The error is from an on-chain mutation (use Mode 5).
+
+### Pattern: Wrap any sub-tree that might throw
+
+```tsx
+import SectionErrorBoundary from '@/components/common/SectionErrorBoundary';
+
+// In LandingPage
+
+ ;
+```
+
+The retry button on the fallback resets the boundary's internal error
+state; it does **not** re-fire the underlying `useQuery`. If you need a
+network retry, combine the boundary with a query that has `enabled` tied
+to a "retry counter" `useState` and bump it inside the retry handler.
+
+### Pair with `throwOnError`
+
+If you want React Query to throw a render-time exception (so the boundary
+catches it) instead of branching on `isError` inside the component, opt in
+on the query:
+
+```ts
+useQuery({
+ queryKey: queryKeys.creators.detail(id),
+ queryFn: () => courseService.getById(id),
+ throwOnError: error => {
+ const api = error as ApiError;
+ // 4xx: render inline; 5xx: bubble to boundary
+ return api.status >= 500;
+ },
+});
+```
+
+See [Error Handling in Hooks → SectionErrorBoundary](./error-handling-in-hooks.md#use-sectionerrorboundary-when)
+for the full reasoning.
+
+---
+
+## Mode 4 — Page-Level Error Boundaries
+
+There are two nested page boundaries; pick the **most specific** one that
+fits the route.
+
+### `CreatorPageErrorBoundary` — creator routes
+
+Scoped to `/creator/:id` and any other creator detail route. When a creator
+page throws, this catches it and renders a fallback with a "back to
+creators" link. It special-cases `ApiError` with `status === 404` to render
+a "Creator not found" message instead of a generic failure.
+
+```tsx
+// src/pages/CreatorDetailPage.tsx
+import CreatorPageErrorBoundary from '@/components/common/CreatorPageErrorBoundary';
+
+export default function CreatorDetailPage() {
+ const { id } = useParams<{ id: string }>();
+ const { data, isLoading, error } = useCreatorDetail(id ?? '');
+
+ if (!data && !isLoading) {
+ throw new ApiError('Creator not found', 404);
+ }
+ if (error) {
+ throw error; // → CreatorPageErrorBoundary
+ }
+
+ return {routes} ;
+```
+
+### `AppErrorBoundary` — last line of defense
+
+Mounted once in [`src/App.tsx`](./../src/App.tsx) around the router. When
+something throws that isn't caught by a more specific boundary, this is
+the last chance before React would otherwise unmount the entire tree. The
+fallback offers a **full page reload** rather than resetting local state —
+the rationale is documented in the component's source comment.
+
+Reach: anything that escapes a `SectionErrorBoundary` or
+`CreatorPageErrorBoundary` will land here.
+
+---
+
+## Mode 5 — Transaction Failure Surfaces
+
+Buy / sell / claim trades have **two** surfaces: an inline
+`TransactionRetryNotice` so the user sees a persistent recovery prompt,
+and a modal `TransactionFailureDrawer` for full diagnostic detail.
+
+### When to use both together
+
+A failed trade should:
+
+1. Show a `TransactionRetryNotice` in place of the trade action area —
+ it stays visible until the user retries or dismisses.
+2. Open a `TransactionFailureDrawer` so the user can copy the error code
+ or transaction hash for support.
+
+```tsx
+// src/components/common/CreatorCard.tsx (excerpt)
+import TransactionRetryNotice from '@/components/common/TransactionRetryNotice';
+import TransactionFailureDrawer from '@/components/common/TransactionFailureDrawer';
+import type { TransactionFailureDetails } from '@/components/common/TransactionFailureDrawer';
+
+const [failure, setFailure] = useState(null);
+
+const handleTrade = async (amount: number) => {
+ try {
+ await buyKey({ creatorId, amount });
+ } catch (err) {
+ const apiError = err as ApiError;
+ setFailure({
+ errorMessage: apiError.message,
+ errorCode: apiError.response?.code,
+ txHash: undefined, // chain-specific; pass when available
+ timestamp: Date.now(),
+ developerDetails: apiError.response,
+ });
+ }
+};
+
+return (
+ <>
+ {failure && (
+ <>
+ {
+ setFailure(null);
+ handleTrade(lastAmount);
+ }}
+ />
+ {
+ setFailure(null);
+ handleTrade(lastAmount);
+ }}
+ onDismiss={() => setFailure(null)}
+ />
+
+ )}
+
+);
+```
+
+`TransactionFailureDetails`:
+
+| Field | Type | Purpose |
+| ------------------ | -------------------------- | ---------------------------------------------- |
+| `errorMessage` | `string` (required) | User-facing message displayed in the drawer |
+| `txHash` | `string?` | On-chain hash for support; copy-to-clipboard |
+| `errorCode` | `string?` | Machine code (e.g. `INSUFFICIENT_BALANCE`) |
+| `timestamp` | `number?` | Unix ms; rendered via `formatTimestampTooltip` |
+| `developerDetails` | `Record?` | Hidden behind a `` toggle for devs |
+
+See [`src/components/common/TransactionFailureDrawer.tsx`](./../src/components/common/TransactionFailureDrawer.tsx)
+for the component contract.
+
+### When to NOT use the drawer
+
+If the action is not on-chain (share, copy, follow) — toast only. The
+drawer exists to expose blockchain-detail information; if there is no
+chain context, it adds noise.
+
+---
+
+## Mode 6 — Network Mismatch Banner
+
+`NetworkMismatchBanner` is **always-on**: it reads from
+`useNetworkMismatch()` and returns `null` when the wallet is on the
+correct network. Mount it once in any layout where users can initiate
+trades; it renders nothing in the happy path.
+
+```tsx
+// Wherever the user can trade
+
+
+```
+
+This is **not** an error per se — it's a precondition warning. Do **not**
+also toast "wrong network" on top of this banner; the banner is the
+canonical surface.
+
+---
+
+## Branching on `ApiError.status` — Consolidated Cheat Sheet
+
+The same numeric scale drives every mode. Source:
+[`src/services/api.service.ts`](./../src/services/api.service.ts) →
+[`BaseApiService.handleError`](./../src/services/api.service.ts).
+
+| `apiError.status` | Meaning | Toast copy | Inline copy | Boundary fallback |
+| ----------------- | ------------------------ | ---------------------------------------------------------- | ------------------------------------------- | ----------------------------------------------- |
+| `0` | No network response | "Network error. Check your connection and try again." | "Check your connection and try again." | `AppErrorBoundary` |
+| `400` | Malformed request | `apiError.message` (safe) | `apiError.message` | `AppErrorBoundary` |
+| `401` | Session expired | (interceptor handles — auto-refresh, redirect to `/login`) | n/a | n/a |
+| `403` | Insufficient permissions | `apiError.message` | "You don't have access to this." | `AppErrorBoundary` |
+| `404` | Resource not found | `apiError.message` | "Not found." | `CreatorPageErrorBoundary` (404 special-cases) |
+| `422` | Validation failure | `apiError.response.errors[0].message` (first field error) | Map every `response.errors[i]` to its input | `AppErrorBoundary` |
+| `429` | Rate limited | "Too many requests. Please wait a moment and retry." | "Rate limited. Try again shortly." | `AppErrorBoundary` |
+| `>= 500` | Server error | "The server ran into a problem. Please try again shortly." | "Unable to load this. Try again later." | Section-level (skeleton→empty→relies on inline) |
+
+---
+
+## Adding a New Error Type to the Classification System
+
+The codebase has **two** classification helpers that capture domain
+specifics. Pick the one that matches your domain; do not invent a new
+helper unless neither fits.
+
+### 1. Wallet & signature errors → extend `WALLET_ERROR_COPY`
+
+File: [`src/utils/errorHandling.utils.ts`](./../src/utils/errorHandling.utils.ts).
+
+Centralized map of wallet-and-signature messages, plus detection helpers:
+
+```ts
+export const WALLET_ERROR_COPY = {
+ SIGNATURE_REJECTED:
+ "Signature request was declined. Please try again when you're ready to confirm.",
+ SIGNATURE_FAILED:
+ 'The signature request failed. Please ensure your wallet is unlocked and try again.',
+ GENERIC_TRANSACTION_FAILED:
+ 'Transaction failed. Please check your balance or connection and try again.',
+};
+
+export function isUserRejection(error: unknown): boolean {
+ /* … */
+}
+export function getSignatureErrorMessage(error: unknown): string {
+ /* … */
+}
+```
+
+**To add a new wallet error type:**
+
+1. Append a new key to `WALLET_ERROR_COPY` with a sentence that states the
+ cause and the next step.
+2. If the detector matters, extend `isUserRejection`-style recognition in
+ a new exported predicate (`isRateLimited(error)`, `isChainSwitchRequired(error)`).
+3. Wire the predicate + key into the calling hook's `onError` — usually
+ by extending `getSignatureErrorMessage` or introducing a sibling
+ `getWalletErrorMessage` if the surface is broader than signatures.
+4. Add a Vitest unit test under
+ `src/utils/__tests__/errorHandling.utils.test.ts` that pins the new
+ copy and predicate behavior.
+
+### 2. Pre-action disabled reasons → extend the typed helper
+
+File: [`src/utils/claimActionDisabledReason.ts`](./../src/utils/claimActionDisabledReason.ts).
+
+Pattern: a **closed union** of reason keys + a **single `Record`** that
+maps each key to a standardized copy. This pattern is reused for other
+disabled-reason surfaces (see `BuyActionHelperText` and
+`ClaimActionHelperText` documentation).
+
+```ts
+export type ClaimActionDisabledReasonKey =
+ | 'wallet_not_connected'
+ | 'no_claimable_rewards'
+ | 'claim_in_progress'
+ | 'network_mismatch'
+ | 'insufficient_gas'
+ | 'unknown';
+
+const CLAIM_ACTION_DISABLED_REASON_TEXT: Record<
+ ClaimActionDisabledReasonKey,
+ string
+> = {
+ // Every entry follows the same shape:
+ // "{Action} is unavailable because {cause}. {Next step}."
+ wallet_not_connected:
+ 'Claim is unavailable because your wallet is not connected. Connect your wallet to continue.',
+ // …
+};
+
+export const getClaimActionDisabledReasonText = (
+ reason: ClaimActionDisabledReasonKey
+): string => CLAIM_ACTION_DISABLED_REASON_TEXT[reason];
+```
+
+**To add a new disabled reason:**
+
+1. Append the new key to the union — **don't** fall back to `unknown`
+ silently; force every caller to make a decision.
+2. Add a matching entry to `CLAIM_ACTION_DISABLED_REASON_TEXT` using the
+ "{Action} is unavailable because {cause}. {Next step}." template so
+ tones stay consistent.
+3. Compute the new key at the call site (the component that evaluates
+ pre-conditions) and pass it to `getClaimActionDisabledReasonText`.
+4. Extend
+ `src/utils/__tests__/claimActionDisabledReason.test.ts` to cover the
+ new key.
+
+### 3. When neither helper fits
+
+If your error surface is genuinely new (e.g. diverging-chain detection,
+on-chain simulation errors), create a new sibling helper in
+`src/utils/ErrorHandling.utils.ts` following the same shape:
+
+1. **Closed key union** — TypeScript exhaustiveness forces callers to
+ pick a copy.
+2. **One Record/Map** that owns _all_ English copy — no copy scattered
+ across components.
+3. **Pure functions** — no React, no hooks, no side effects. Easy to
+ unit-test.
+4. **Side-by-side tests** — colocated unit test in
+ `src/utils/__tests__/`.
+
+Do not duplicate copy inline in components; always go through a typed
+helper so future copy edits stay coherent.
+
+---
+
+## Shared Error State Components — Reference
+
+| Component | Mode | Purpose | Key props |
+| -------------------------------------------------- | ---- | --------------------------------------------------- | ------------------------------------------------------------------------- |
+| `showToast` (`@/utils/toast.util`) | 1 | Mutation feedback (success, error, loading, tx) | `showToast.{success,error,loading,transactionSuccess}(message, options?)` |
+| `CreatorProfileErrorState` (`@/components/common`) | 2 | Canonical inline error card for creator profile | `error?, onRetry?, isRetrying?, title?, message?` |
+| `SectionErrorBoundary` (`@/components/common`) | 3 | Catches sub-tree render throws with retry | `sectionName?, minHeight?, className?` |
+| `CreatorPageErrorBoundary` (`@/components/common`) | 4 | Catches creator-route render throws | none (wraps ``) |
+| `AppErrorBoundary` (`@/components/common`) | 4 | App-wide last-line-of-defense; full reload on retry | none (wraps ``) |
+| `TransactionRetryNotice` (`@/components/common`) | 5 | Persistent inline retry banner for failed trades | `title?, message, onRetry, retryLabel?, disabled?, className?` |
+| `TransactionFailureDrawer` (`@/components/common`) | 5 | Modal with error code, hash, and developer details | `open, onOpenChange?, failureDetails, onRetry?, onDismiss?` |
+| `NetworkMismatchBanner` (`@/components/common`) | 6 | Persistent "wrong network" warning | `className?` |
+

+[Adding a Page and Data Fetching](./adding-page-and-data-fetching.md)
+and [Shared Components](./shared-components.md).
+
+---
+
+## Worked Examples
+
+### Example A — Marketplace search list (read failure → Mode 2)
+
+The creator list inside the marketplace is critical content, so a query
+failure renders an inline state with retry. The rest of the page
+(hero, holdings, footer) stays interactive.
+
+```tsx
+// src/pages/LandingPage.tsx (excerpt)
+const { data: creators, isError, error, refetch } = useCreatorList();
+
+if (isError) {
+ const apiError = error as ApiError;
+ return (
+
+ Couldn't load the creator list
+
+ {apiError.status >= 500
+ ? 'Something went wrong on our end. Please try again.'
+ : apiError.message}
+
+
+
+ );
+}
+
+return
+
+ );
+}
+```
+
+### Example C — Buy flow (mutation failure → Mode 1 + Mode 5)
+
+A trade mutation has both the prompt (toast), the persistent retry
+banner, and the detail drawer:
+
+```tsx
+// src/components/common/CreatorCard.tsx (excerpt)
+const buy = useBuyCreatorKey();
+
+const handleBuy = async (amount: number) => {
+ try {
+ await buy.mutateAsync({ creatorId, amount });
+ } catch (err) {
+ const apiError = err as ApiError;
+
+ // Mode 1: quick prompt
+ showToast.error(
+ apiError.status === 0
+ ? 'Network error. Check your connection.'
+ : apiError.message
+ );
+
+ // Mode 5: persistent banner + drawer for support detail
+ setFailure({
+ errorMessage: apiError.message,
+ errorCode: apiError.response?.code,
+ timestamp: Date.now(),
+ });
+ }
+};
+```
+
+---
+
+## Quick Reference
+
+| Question | Answer |
+| ----------------------------------------------------- | ----------------------------------------------------- |
+| Failure from a button click? | Toast (Mode 1), add drawer for on-chain trades |
+| Failure from `useQuery` that **is** the page? | Throw → Page boundary (Mode 4) |
+| Failure from `useQuery` that **enriches** the page? | Inline state with `refetch` (Mode 2) |
+| Component throws during render (not a query error)? | Wrap in `SectionErrorBoundary` (Mode 3) |
+| Wallet is connected but wrong chain? | `NetworkMismatchBanner` (Mode 6) |
+| User clicked "Cancel" on the wallet signature prompt? | `getSignatureErrorMessage` (Mode 1, specialised copy) |
+| New kind of wallet error? | Extend `WALLET_ERROR_COPY` |
+| New pre-action disabled reason? | Extend `ClaimActionDisabledReasonKey` + lookup |

+# Error Handling in React Query Hooks
+
+This guide documents the standard pattern for handling API errors in React Query hooks across this codebase. Follow it when writing new `useQuery` or `useMutation` hooks so error behavior is consistent and predictable for users.
+
+---
+
+## How Errors Flow In
+
+All HTTP requests go through the service layer (`src/services/`), which extends `BaseApiService`. The `handleError` method on that base class normalises every failure into an `ApiError` before it reaches the hook:
+
+| Raw failure | What you receive |
+| ------------------------------------- | ------------------------------------------------------ |
+| HTTP response with an error status | `ApiError(message, httpStatus, responseBody)` |
+| Request sent but no response received | `ApiError('Network error - check your connection', 0)` |
+| Unexpected non-HTTP exception | `ApiError(error.message, 500)` |
+
+One important exception: **401 + `TOKEN_EXPIRED`** is handled transparently by the Axios interceptor in `BaseApiService`. The interceptor silently retries the original request after refreshing the access token. If the refresh also fails the user is redirected to `/login`; the hook never sees this error.
+
+---
+
+## The `ApiError` Shape
+
+```ts
+// src/services/api.service.ts
+class ApiError extends Error {
+ status: number; // HTTP status code; 0 means no network response
+ response?: {
+ success: false;
+ message: string;
+ code?: string; // machine-readable code from the API, e.g. "INSUFFICIENT_BALANCE"
+ errors?: Array<{
+ field?: string; // present on 422 validation failures
+ message: string;
+ }>;
+ };
+}
+```
+
+Always cast the error to `ApiError` before inspecting it:
+
+```ts
+import { ApiError } from '@/services/api.service';
+
+onError: error => {
+ const apiError = error as ApiError;
+ console.log(apiError.status); // 0, 400, 403, 422, 500 …
+ console.log(apiError.message); // human-readable message from the API
+ console.log(apiError.response?.errors); // field-level details on 422
+};
+```
+
+---
+
+## Distinguishing Error Types
+
+### Network errors (`status === 0`)
+
+No response was received — the user is offline, the server is unreachable, or a timeout occurred. The user cannot fix the request payload; they need to retry later.
+
+```ts
+if (apiError.status === 0) {
+ showToast.error('Network error. Check your connection and try again.');
+ return;
+}
+```
+
+### 4xx — Client errors
+
+The request was received but rejected because of something the client sent. The message from the API is usually safe to show to the user.
+
+| Status | Cause | Typical UI response |
+| ------ | ------------------------ | ---------------------------------------------------- |
+| 400 | Malformed request | Toast with `apiError.message` |
+| 401 | Session expired | Auto-handled by the interceptor |
+| 403 | Insufficient permissions | Inline error or redirect |
+| 404 | Resource not found | Inline error state |
+| 422 | Validation failure | Inline field errors from `apiError.response?.errors` |
+| 429 | Rate limited | Toast with retry suggestion |
+
+### 5xx — Server errors
+
+The API itself failed. The user cannot fix the payload; they can only retry after the server recovers. Avoid showing raw server messages — use a generic fallback instead.
+
+```ts
+if (apiError.status >= 500) {
+ showToast.error('The server ran into a problem. Please try again shortly.');
+ return;
+}
+```
+
+---
+
+## Deciding: Toast vs. Inline Error vs. Error Boundary
+
+### Use a toast when
+
+- The failure came from a **user-initiated action** (mutation): buying a key, submitting a form, enrolling in a course.
+- The error **does not block the current view** — the page can still render usefully.
+- The fix is to retry or change input: one line of feedback is enough.
+
+```ts
+onError: error => {
+ const apiError = error as ApiError;
+ showToast.error(
+ apiError.status >= 500
+ ? 'Something went wrong. Try again.'
+ : apiError.message
+ );
+};
+```
+
+### Use an inline error state when
+
+- The error **blocks the primary purpose of the screen** — for example, the creator list failed to load so the page is empty.
+- The error contains **field-level detail** (422) that needs to map to specific form inputs.
+- The user needs to take **corrective action** (fix a field, switch networks) before retrying makes sense.
+
+```tsx
+const { data, isError, error } = useCreatorKeys(creatorId);
+
+if (isError) {
+ const apiError = error as ApiError;
+ return (
+
+ {apiError.status >= 500
+ ? 'Unable to load data. Please try again later.'
+ : apiError.message}
+
+ );
+}
+```
+
+### Use `SectionErrorBoundary` when
+
+- A **component throws during render**, not from an API call.
+- You want to **isolate a section** so one broken widget does not crash the whole page.
+- React Query's `throwOnError` option is enabled on a query.
+
+```tsx
+import SectionErrorBoundary from '@/components/common/SectionErrorBoundary';
+
+
+ ;
+```
+
+`SectionErrorBoundary` renders a retry button that resets its own error state. Use it as a safety net around sections that fetch and render data together.
+
+---
+
+## `useQuery` Pattern
+
+React Query v5 removed the `onError` callback from `useQuery`. Errors surface through `isError` and `error` in the component. Keep the hook thin and handle the error at the call site:
+
+```ts
+// src/hooks/useCreatorProfile.ts
+import { useQuery } from '@tanstack/react-query';
+import { creatorService } from '@/services/creator.service';
+
+export function useCreatorProfile(creatorId: string) {
+ return useQuery({
+ queryKey: ['creator-profile', creatorId],
+ queryFn: () => creatorService.getProfile(creatorId),
+ staleTime: 30_000,
+ });
+}
+```
+
+```tsx
+// In the component
+import { ApiError } from '@/services/api.service';
+import { useCreatorProfile } from '@/hooks/useCreatorProfile';
+
+function CreatorProfileSection({ creatorId }: { creatorId: string }) {
+ const { data, isLoading, isError, error } = useCreatorProfile(creatorId);
+
+ if (isLoading) return
+ {apiError.status >= 500
+ ? 'Unable to load keys right now. Please try again later.'
+ : apiError.message}
+
+
+ );
+ }
+
+ return (
+ // SectionErrorBoundary catches any render-time throws inside KeysList
+
+ buyKey({ creatorId, amount })}
+ isBuying={isPending}
+ />
+
+ );
+}
+```
+
+---
+
+## Quick Reference
+
+| Condition | Check | UI response |
+| ------------------- | ------------------------------- | ------------------------------------------------------------ |
+| No network response | `apiError.status === 0` | Toast: "Network error. Check your connection." |
+| Server error | `apiError.status >= 500` | Toast: generic "something went wrong" message |
+| Validation failure | `apiError.status === 422` | Toast or inline: first item from `apiError.response?.errors` |
+| Other 4xx | `apiError.status >= 400` | Toast or inline: `apiError.message` (safe from the API) |
+| Read query fails | `isError === true` in component | Inline error state replacing the content area |
+| Render throws | Component boundary | Wrap with `` |

+# Editing Marketing Page Copy
+
+This guide is for non-technical contributors who want to suggest changes to the
+marketing page copy. You can edit the text directly on GitHub and open a pull
+request — no local development environment is required.
+
+## Where the copy lives
+
+All marketing page copy is in a single file:
+
+**`src/pages/MarketingPage.tsx`**
+
+The page is a single React component. Each visible section is a block of JSX
+with inline text. Use the table below to find the section you want to change.
+
+| Visible section on the page | Location in `MarketingPage.tsx` | What to look for |
+| ------------------------------- | ----------------------------------------- | ------------------------------------------------------------------------------ |
+| Page title ("Access Layer") | Hero / Title | `` with the `Access Layer` heading |
+| Intro paragraph under the title | Intro | First `
` after the title |
+| **The idea** | `{/* The idea */}` section | Eyebrow text `The idea` and the two body paragraphs below it |
+| **How it works** | `{/* How it works */}` section | Eyebrow text `How it works` and the two body paragraphs below it |
+| **What makes it different** | `{/* What makes it different */}` section | Eyebrow text `What makes it different` and the body paragraph below it |
+| **Built on Stellar** | `{/* Built on Stellar */}` section | Eyebrow text `Built on Stellar` and the two body paragraphs below it |
+| **Join the community** | `{/* Community */}` section | Eyebrow text `Join the community`, the subtitle, and the GitHub/Telegram links |
+| Footer | `{/* Footer */}` section | Logo label and the "Built on Stellar" tagline |
+
+Section eyebrows use this pattern — a short uppercase label in blue:
+
+```tsx
+
+ The idea

+```

+/**
+ * Integration test for holdings entry count after buy/sell sequence (#TBD).
+ *
+ * The holdings list should add an entry when a buy confirms for a new creator
+ * and remove it when all keys for that creator are sold. Additional keys for
+ * an existing creator must not produce a duplicate entry.
+ *
+ * Held positions are derived from the API response:
+ * index 0 → featuredHoldings (mutable via TradeDialog, starts at 3)
+ * index 1+ → DEMO_HELD_KEY_QUANTITIES (fixed per session)
+ *
+ * Flow (2 creators returned by the API):
+ * 1. Initial: featuredHoldings=3 (Creator A) + 2 keys (Creator B) → 2 entries
+ * 2. Sell all 3 keys of Creator A → 1 entry (only Creator B)
+ * 3. Buy 1 key of Creator A → 2 entries (A re-added, B still present)
+ * 4. Buy 2 more keys of Creator A → still 2 entries (no duplicate)
+ * 5. Sell all 3 keys of Creator A → 1 entry (only Creator B again)
+ *
+ * Acceptance criteria covered:
+ * - Entry added when a buy confirms for a new creator (step 3)
+ * - Entry not duplicated when additional keys are bought (step 4)
+ * - Entry removed when all keys for a creator are sold (steps 2, 5)
+ * - Entry count correct after each state change (all steps)

` following semantic hierarchy.
+- **Import shared components** with the `@/` alias (e.g., `@/components/common/Button`).
+- **Use existing fonts and colors** — don't introduce new global styles for a single page. Stick to `font-grotesque`, `font-jakarta`, and the dark blue palette (`bg-[#06111f]`, `text-white/70`).
+
+---
+
+## Part 2: Route Registration
+
+Routes are registered in a **single source of truth** at `src/routes.tsx`. Add your new page there:
+
+```tsx
+// src/routes.tsx
+import HomePage from './pages/HomePage';
+import CreatorDetailPage from './pages/CreatorDetailPage';
+import YourNewPage from './pages/YourNewPage'; // ← import your page
+
+export const routes = [
+ {
+ path: '/',
+ element: {/* render your page with data */} ;
+}
+```
+
+### Query Key Factory Pattern
+
+All React Query keys are defined in a **single central factory** at `src/lib/queryKeys.ts`. This keeps key shapes predictable and invalidation reliable.
+
+**Key structure:**
+
+```ts
+export const queryKeys = {
+ yourEntity: {
+ all: ['yourEntity'] as const,
+ list: (params?: GetYourParams) =>
+ ['yourEntity', 'list', params ?? null] as const,
+ detail: (id: string) => ['yourEntity', 'detail', id] as const,
+ holders: (entityId: string) =>
+ ['yourEntity', entityId, 'holders'] as const,
+ },
+};
+```
+
+**Key rules:**
+
+1. **`all` key** — every entity group has a static `all` key for bulk invalidation.
+2. **Shared prefixes** — all keys in a group start with the same entity name so prefix-based invalidation works.
+3. **`as const`** — return `as const` tuples so TypeScript infers literal types.
+4. **Optional params become `null`** — when a list query has no filters, store `null` at the param position for consistent key shape.
+
+**Add your entity to the factory:**
+
+```ts
+// src/lib/queryKeys.ts (existing)
+
+import type { GetYourParams } from '@/services/your.service';
+
+export const queryKeys = {
+ creators: {
+ /* ... */
+ },
+ wallet: {
+ /* ... */
+ },
+ yourEntity: {
+ all: ['yourEntity'] as const,
+ list: (params?: GetYourParams) =>
+ ['yourEntity', 'list', params ?? null] as const,
+ detail: (id: string) => ['yourEntity', 'detail', id] as const,
+ },
+};
+```
+
+See [docs/react-query-cache-conventions.md](./react-query-cache-conventions.md) for full details on cache invalidation patterns.
+
+### Loading and Error States
+
+Always handle the three states: `isLoading`, `error`, and `data`:
+
+```tsx
+import { CreatorProfileHeaderSkeleton } from '@/components/common/CreatorSkeleton';
+import { ApiError } from '@/services/api.service';
+
+export default function YourDetailPage() {
+ const { id } = useParams<{ id: string }>();
+ const { data, isLoading, error } = useYourData(id || '');
+
+ // 1. LOADING: Show a skeleton while fetching
+ if (isLoading) {
+ return (
+
+
+ );
+ }
+
+ // 2. ERROR: Throw to error boundary or render error UI
+ if (error) {
+ throw error; // handled by error boundary (see Part 5)
+ }
+
+ // 3. NO DATA: Throw a 404 error
+ if (!data) {
+ throw new ApiError('Not found', 404);
+ }
+
+ // 4. SUCCESS: Render your page
+ return (
+
+ {data.title}
+ {/* render data */}
+
+ );
+}
+```
+
+### Stale Time Configuration
+
+React Query data is stale immediately by default (`staleTime: 0`). Override this for data that changes infrequently:
+
+```ts
+useQuery({
+ queryKey: queryKeys.yourEntity.detail(id),
+ queryFn: () => yourService.fetchData(id),
+ staleTime: 30_000, // data is fresh for 30 seconds
+});
+```
+
+| Data Type | Recommended staleTime | Rationale |
+| -------------------------------- | --------------------- | ------------------------------ |
+| Real-time (prices, balances) | `0` (default) | Always show the latest value |
+| Semi-static (profiles, metadata) | `30_000` – `60_000` | Balance freshness vs refetches |
+| Rarely-changing (lists, config) | `5 * 60_000` (5 min) | Reduce bandwidth |
+| Truly static | `Infinity` | Fetch once per session |
+
+See [docs/react-query-cache-conventions.md](./react-query-cache-conventions.md#stale-time-and-cache-time) for full details.
+
+---
+
+## Part 4: Service Layer and Data Types
+
+Data fetching happens through a **service layer** in `src/services/`. Each service is a class that extends `BaseApiService` and handles a domain (creators, wallet, etc.).
+
+**Example:**
+
+```ts
+// src/services/your.service.ts
+import { BaseApiService, type APIResponse } from './api.service';
+
+export interface YourEntity {
+ id: string;
+ title: string;
+ description: string;
+ // ... other fields
+}
+
+class YourService extends BaseApiService {
+ async getYourData(id: string): Promise {
+ try {
+ const response = await this.api.get>(
+ `/your-endpoint/${id}`
+ );
+ return response.data.data;
+ } catch (error) {
+ throw this.handleError(error);
+ }
+ }
+}
+
+export const yourService = new YourService();
+```
+
+Then import and use it in your hook:
+
+```ts
+// src/hooks/useYourData.ts
+import { yourService } from '@/services/your.service';
+
+export function useYourData(id: string) {
+ return useQuery({
+ queryKey: queryKeys.yourEntity.detail(id),
+ queryFn: () => yourService.getYourData(id),
+ enabled: !!id,
+ });
+}
+```
+
+See [docs/api-layer.md](./api-layer.md) for full service layer conventions.
+
+---
+
+## Part 5: Layout Components and Error Boundaries
+
+### When to Use Shared Layouts
+
+Check `src/components/common/` for existing layout and wrapper components:
+
+- **`CreatorPageErrorBoundary`** — wraps creator pages to catch and handle errors
+- **`SectionErrorBoundary`** — wraps individual sections to handle errors in one area without crashing the whole page
+- **`SectionHeading`** — formats section titles consistently
+- **`CardMetaRow`** — displays metadata in a consistent card row style
+
+Use these when they fit. Don't create a new layout component unless an existing one truly doesn't match your needs.
+
+### Error Boundaries for Pages
+
+Wrap your page content in an error boundary to catch and display errors gracefully:
+
+```tsx
+// src/pages/YourDetailPage.tsx
+import YourPageErrorBoundary from '@/components/common/YourPageErrorBoundary';
+
+function YourDetailPageContent() {
+ // ... your page logic with data fetching
+ return {/* content */} ;
+}
+
+export default function YourDetailPage() {
+ return (
+
+
+ );
+}
+```
+
+If a similar error boundary exists (e.g., `CreatorPageErrorBoundary`), study it and reuse or adapt it. Create a new one only if your error handling is significantly different.
+
+---
+
+## Part 6: Complete Minimal Example
+
+Here's a full example adding a new page called `/creators` that lists all creators:
+
+### Step 1: Create the Page
+
+```tsx
+// src/pages/CreatorListPage.tsx
+import { useCreatorList } from '@/hooks/useCreatorList';
+import CreatorCard from '@/components/common/CreatorCard';
+import { CreatorCardGridSkeleton } from '@/components/common/CreatorCardSkeleton';
+import { ApiError } from '@/services/api.service';
+
+function CreatorListPageContent() {
+ const { data: creators, isLoading, error } = useCreatorList();
+
+ if (isLoading) {
+ return (
+
+
+ );
+ }
+
+ if (error) {
+ throw error;
+ }
+
+ if (!creators || creators.length === 0) {
+ throw new ApiError('No creators found', 404);
+ }
+
+ return (
+
+
+ All Creators
+
+
+ {creators.map(creator => (
+
+ );
+}
+
+export default function CreatorListPage() {
+ return Page'` path shown above, matching the existing imports.
+- **Do not** create a second router or wrap the app in another `Page` | `export default function AboutPage()` |
+
+The component itself uses `export default function Page()` — not a named export, and not an arrow const. This keeps imports straightforward and matches every existing page in `src/pages/`:
+
+```
+src/pages/
+├── HomePage.tsx // registered as '/'
+├── MarketingPage.tsx // exists on disk, not yet registered
+├── LandingPage.tsx // exists on disk, not yet registered
+└── NotFoundPage.tsx // registered as '*' (catch-all)
+```
+
+A few pages exist as files but are not currently wired into the router in `src/App.tsx`. They are kept on disk because they are planned routes waiting on the marketplace flows to land. If you need one of them live, follow this guide to register it like any other page.
+
+### What a page component looks like
+
+Top-level page components take **no props**. They own their own layout, fetching, and state. A minimal page is just a function that returns JSX:
+
+```tsx
+// src/pages/AboutPage.tsx
+export default function AboutPage() {
+ return (
+
+
+ About Access Layer
+
+
+ Access Layer is a Stellar-native creator keys marketplace.
+
+
+ );
+}
+```
+
+Conventions to follow:
+
+- **Default export only.** Named exports break the import in `App.tsx`.
+- **One component per file.** Don't lump multiple pages into a single file.
+- **No props.** Reach for URL params via `useParams()` from `react-router` instead of prop drilling.
+- **Accessibility:** wrap content in a single `` landmark and use semantic headings (`` for the page title).
+- **Match the project styling.** Use the existing `font-grotesque`, `font-jakarta`, and dark-on-blue palette referenced throughout the codebase. Don't introduce new global styles for a single page.
+- **Use the `@/` alias for component imports.** The project-wide path alias `@/` maps to `src/` (configured via Vite + TypeScript path mapping). Use it freely from any component file; reserve short relative paths like `'../pages/Page'` for tight sibling-file imports.
+
+---
+
+## Public vs auth-protected routes
+
+There is **no existing `RequireAuth` / `ProtectedRoute` wrapper** in the codebase yet. Every route registered today is public. When a feature needs auth gating, follow the pattern below — and ship the wrapper component with that feature, since the client doesn't have a standalone auth-guard component yet.
+
+### Recommended pattern
+
+1. Create a small wrapper component, conventionally `src/components/auth/RequireAuth.tsx` (create the `auth/` subfolder if it doesn't exist yet).
+2. Inside the wrapper, check the appropriate auth state — wagmi's `useAccount` for wallet-gated flows, or `authService.isAuthenticated()` for email/login-gated flows.
+3. While the state is resolving, render a lightweight placeholder (the existing `PendingOnboardingPlaceholder` makes a good model).
+4. If unauthenticated, render a redirect or a connect-wallet CTA — do **not** render the protected page.
+5. Wrap the protected page's `element` with the wrapper inside `App.tsx`.
+
+```tsx
+// src/components/auth/RequireAuth.tsx
+import type { ReactNode } from 'react';
+import { useAccount } from 'wagmi';
+import { Navigate, useLocation } from 'react-router';
+import PendingOnboardingPlaceholder from '@/components/common/PendingOnboardingPlaceholder';
+
+interface RequireAuthProps {
+ children: ReactNode;
+}
+
+export default function RequireAuth({ children }: RequireAuthProps) {
+ const { isConnected, isConnecting } = useAccount();
+ const location = useLocation();
+
+ // Show the placeholder while a fresh wallet connection is in flight
+ // so the user isn't redirected to "/" mid-connect. Once it resolves,
+ // isConnected flips to true and we render the protected page below.
+ // Note: isReconnecting is intentionally NOT in this branch — a
+ // reconnect of a prior session keeps the user authenticated, so
+ // rendering the protected page during a reconnect is fine.
+ if (isConnecting) {
+ return :
+ element: (
+
+
+ ),
+ },
+ { path: '*', element: ` is not currently mounted above ``. Any wagmi hook — including `useAccount` inside `RequireAuth` — will throw at runtime because the `WagmiProvider` context is missing. Wiring `` here is an app-level change and should be tracked separately; reference the tracking issue in your route PR description rather than embedding the wiring fix in your route PR.
+2. **Wagmi has a transient `isConnecting` state** while a fresh wallet handshake is in flight. During this window `isConnected` is `false`, but redirecting the user mid-connect would bounce them away. The example above handles this by rendering `PendingOnboardingPlaceholder` for the `isConnecting` branch — copy that pattern verbatim. (Note: `isReconnecting` is _not_ included in that branch — a reconnect of a prior, already-authenticated session keeps the user authenticated, so rendering the protected page during a reconnect is fine and avoids a UX flash.)
+
+If your guard only uses `authService.isAuthenticated()` (no wagmi hooks), neither caveat applies — the helper reads `localStorage` directly.
+
+---
+
+## Worked example — adding a new public page
+
+This walks a contributor end-to-end through adding `AboutPage` at `/about`. The page is public, so no `RequireAuth` wrapper is involved.
+
+### 1. Create the page component
+
+Add a new file at `src/pages/AboutPage.tsx`:
+
+```tsx
+// src/pages/AboutPage.tsx
+import { Link } from 'react-router';
+import { Button } from '@/components/ui/button';
+
+export default function AboutPage() {
+ return (
+
+
+ About Access Layer
+
+
+ Access Layer is a Stellar-native creator keys marketplace built on
+ the open AccessLayer protocol.
+
+
+
+
+
+
+ );
+}
+```
+
+### 2. Register the route
+
+Add the import and a new entry to the router array in `src/App.tsx`:
+
+```tsx
+// src/App.tsx
+import HomePage from './pages/HomePage';
+import NotFoundPage from './pages/NotFoundPage';
+import AboutPage from './pages/AboutPage'; // ← added
+
+const router = createBrowserRouter([
+ { path: '/', element: .service.ts` | `wallet.service.ts` |
+| Class name | `Service` | `WalletService` |
+| Exported singleton | `Service` | `walletService` |
+
+Every service class **extends `BaseApiService`** from `api.service.ts`, which provides:
+
+- A pre-configured Axios instance (`this.api`) pointing at `VITE_BACKEND_URL`
+- Automatic token refresh on `401 TOKEN_EXPIRED` responses
+- A shared `handleError(error)` method that normalises any thrown value to `ApiError`
+
+---
+
+## Error handling
+
+Every service method wraps its Axios call in a `try/catch` and re-throws via `this.handleError`:
+
+```ts
+async getWalletHoldings(address: string): Promise {
+ try {
+ const response = await this.api.get>(
+ `/wallets/${address}/holdings`
+ );
+ return response.data.data;
+ } catch (error) {
+ throw this.handleError(error);
+ }
+}
+```
+
+`handleError` always returns an `ApiError` instance with:
+
+| Field | Type | Description |
+| ---------- | ------------------------------- | ------------------------------------------ |
+| `message` | `string` | Human-readable error message |
+| `status` | `number` | HTTP status code; `0` for network failures |
+| `response` | `APIErrorResponse \| undefined` | Full server error payload when available |
+
+Callers can check `error instanceof ApiError` and inspect `error.status` for branching logic.
+
+---
+
+## How to add a new endpoint
+
+### 1. Add the method to the relevant service file
+
+Open `src/services/.service.ts` (or create a new one if the domain is new). Add a method that:
+
+1. Calls `this.api.get/post/patch/delete`
+2. Extracts `response.data.data`
+3. Re-throws any error via `this.handleError`
+
+```ts
+// src/services/wallet.service.ts
+import { BaseApiService, type APIResponse } from './api.service';
+
+export interface Holding {
+ creatorId: string;
+ quantity: number;
+ priceStroops: number;
+}
+
+class WalletService extends BaseApiService {
+ async getHoldings(address: string): Promise {
+ try {
+ const response = await this.api.get>(
+ `/wallets/${address}/holdings`
+ );
+ return response.data.data;
+ } catch (error) {
+ throw this.handleError(error);
+ }
+ }
+}
+
+export const walletService = new WalletService();
+```
+
+### 2. Define a query key in `src/lib/queryKeys.ts`
+
+Add an entry for the new endpoint so all hooks that reference the same data use an identical cache key:
+
+```ts
+// src/lib/queryKeys.ts
+wallet: {
+ holdings: (address: string) => ['wallet', address, 'holdings'] as const,
+ // ...
+},
+```
+
+### 3. Write a React Query hook
+
+`QueryClientProvider` is already wired up in `src/providers/Web3Provider.tsx` — no setup changes needed.
+
+```ts
+// src/hooks/useWalletHoldings.ts
+import { useQuery } from '@tanstack/react-query';
+import { walletService } from '@/services/wallet.service';
+import { queryKeys } from '@/lib/queryKeys';
+
+export function useWalletHoldings(address: string | undefined) {
+ return useQuery({
+ queryKey: queryKeys.wallet.holdings(address ?? ''),
+ queryFn: () => walletService.getHoldings(address!),
+ enabled: Boolean(address),
+ });
+}
+```
+
+### 4. Consume the hook in a component
+
+```tsx
+import { useWalletHoldings } from '@/hooks/useWalletHoldings';
+
+function HoldingsList({ address }: { address: string }) {
+ const { data: holdings, isLoading, error } = useWalletHoldings(address);
+
+ if (isLoading) return Loading…
;
+ if (error) return Failed to load holdings.
;
+
+ return (
+
+ {holdings?.map(h => (
+ -
+ {h.creatorId} — {h.quantity} keys
+
+ ))}
+
+ );
+}
+```
+
+---
+
+## Worked example — full GET call
+
+The following shows a complete end-to-end flow for a `GET /wallets/:address/holdings` endpoint.
+
+### Service method
+
+```ts
+// src/services/wallet.service.ts
+import { BaseApiService, type APIResponse } from './api.service';
+
+export interface Holding {
+ creatorId: string;
+ quantity: number;
+ priceStroops: number;
+}
+
+class WalletService extends BaseApiService {
+ async getHoldings(address: string): Promise {
+ try {
+ const response = await this.api.get>(
+ `/wallets/${address}/holdings`
+ );
+ return response.data.data;
+ } catch (error) {
+ throw this.handleError(error);
+ }
+ }
+}
+
+export const walletService = new WalletService();
+```
+
+### Query key
+
+```ts
+// src/lib/queryKeys.ts (existing file — add the entry)
+wallet: {
+ holdings: (address: string) => ['wallet', address, 'holdings'] as const,
+},
+```
+
+### Hook
+
+```ts
+// src/hooks/useWalletHoldings.ts
+import { useQuery } from '@tanstack/react-query';
+import { walletService } from '@/services/wallet.service';
+import { queryKeys } from '@/lib/queryKeys';
+
+export function useWalletHoldings(address: string | undefined) {
+ return useQuery({
+ queryKey: queryKeys.wallet.holdings(address ?? ''),
+ queryFn: () => walletService.getHoldings(address!),
+ enabled: Boolean(address),
+ });
+}
+```
+
+### Component
+
+```tsx
+// Usage in any component
+import { useAccount } from 'wagmi';
+import { useWalletHoldings } from '@/hooks/useWalletHoldings';
+
+function HoldingsSummary() {
+ const { address } = useAccount();
+ const { data: holdings, isLoading, error } = useWalletHoldings(address);
+
+ if (isLoading) return Loading…
;
+ if (error) return Could not load holdings.
;
+ if (!holdings?.length) return No holdings yet.
;
+
+ return (
+
+ {holdings.map(h => (
+ -
+ {h.creatorId} — {h.quantity} keys at {h.priceStroops} stroops
+
+ ))}
+
+ );
+}
+```

+# Environment Variable Guide
+
+This guide explains how to add a new client environment variable safely and consistently in Access Layer Client.
+
+The client is built with Vite, so any value that must be available in browser code must use the `VITE_` prefix. Values without that prefix are not exposed to the client bundle.
+
+## Files involved
+
+| File | Purpose |
+| ------------------------ | ---------------------------------------------------------------------------------------------------------------- |
+| `.env.example` | Documents every supported variable and provides safe local defaults or blank optional placeholders. |
+| `src/utils/env.utils.ts` | Validates environment variables at startup with Zod and exports the typed `env` object used by application code. |
+| `.env` | Local developer overrides. This file should not be committed. |
+
+## Add a new variable
+
+1. Add the variable to `.env.example`.
+2. Add validation for the variable in `src/utils/env.utils.ts`.
+3. Pass the raw `import.meta.env` value into the `envSchema.parse(...)` call in `src/utils/env.utils.ts`.
+4. Import the validated `env` object in application code.
+5. Avoid reading `import.meta.env` directly from components, hooks, or service files.
+
+## Declaration pattern
+
+Add the new variable to `.env.example` near related settings. Use a short comment that explains what the value controls and whether it is required.
+
+```env
+# Feature flag for the creator discovery experiment. Use `true` to enable locally.
+VITE_ENABLE_CREATOR_DISCOVERY=false
+```
+
+Prefer safe development defaults when the app can run without secrets. Leave optional third-party keys blank if a contributor can work without them.
+
+## Runtime validation pattern
+
+All supported variables should be declared in `src/utils/env.utils.ts` so missing or malformed configuration is caught in one place.
+
+```ts
+const envSchema = z.object({
+ VITE_ENABLE_CREATOR_DISCOVERY: z.coerce.boolean().default(false),
+});
+
+export const env = envSchema.parse({
+ VITE_ENABLE_CREATOR_DISCOVERY: import.meta.env.VITE_ENABLE_CREATOR_DISCOVERY,
+});
+```
+
+Use the Zod type that matches how the app consumes the value:
+
+| Value type | Validation example |
+| --------------- | ----------------------------------------------- |
+| Required string | `z.string().min(1, "VITE_API_KEY is required")` |
+| Optional string | `z.string().optional()` |
+| Number | `z.coerce.number().default(84532)` |
+| Boolean flag | `z.coerce.boolean().default(false)` |
+
+If a value is required for the app to start, avoid a silent fallback. Use `.min(1, "... is required")` or another explicit validation rule so the startup error points to the missing variable.
+
+## Access pattern in application code
+
+Import `env` from the validation module and read the typed value from there:
+
+```ts
+import { env } from '@/utils/env.utils';
+
+if (env.VITE_ENABLE_CREATOR_DISCOVERY) {
+ // Render or enable the feature.
+}
+```
+
+This keeps validation, defaults, and type coercion centralized.
+
+## Anti-pattern: direct component access
+
+Do not import or read `import.meta.env` directly in components, hooks, services, or utilities outside the validation module.
+
+```tsx
+// Avoid this.
+const backendUrl = import.meta.env.VITE_BACKEND_URL;
+```
+
+Direct access bypasses schema validation, makes defaults inconsistent, and spreads environment knowledge across the app. Use `env` instead:
+
+```tsx
+import { env } from '@/utils/env.utils';
+
+const backendUrl = env.VITE_BACKEND_URL;
+```
+
+## Required vs optional checklist
+
+Use this checklist before opening a PR that adds a new variable:
+
+- The variable is listed in `.env.example`.
+- The variable has a clear comment describing its purpose.
+- Required values fail fast in `src/utils/env.utils.ts` with a useful error.
+- Optional values use `.optional()` or a safe `.default(...)`.
+- Application code reads from `env`, not `import.meta.env`.
+- The variable name starts with `VITE_` if browser code needs it.

+# Error Handling Conventions
+
+> Issue #630 — Establish the expected pattern for every error category
+> (boundary, query state, mutation feedback, transaction surface, network
+> warning) so the UI feels consistent regardless of which component rendered
+> the error.
+
+This guide is the **single source of truth** for how errors are surfaced in
+the Access Layer client. Pair it with
+[Error Handling in React Query Hooks](./error-handling-in-hooks.md) for the
+hook-side `ApiError` branching detail and
+[State Management](./state-management.md) for the
+[Error Architecture Strategy](./state-management.md#3-error-architecture-strategy-boundary-vs-inline-states)
+section that motivates the boundary/inline split.
+
+---
+
+## The Five Error Display Modes
+
+Every error in the client surfaces through **one of five modes**. Pick the
+right one based on where the error came from and what the user still needs
+to be able to do.
+
+| # | Mode | Trigger | Audience | Component (canonical) |
+| --- | -------------------- | --------------------------------------- | --------------- | ----------------------------------------------------- |
+| 1 | **Toast** | `useMutation.onError` (user action) | Glanceable | `showToast.error` from `@/utils/toast.util` |
+| 2 | **Inline state** | `useQuery` `isError` (blocking content) | Focused | `CreatorProfileErrorState`, section-level cards |
+| 3 | **Section boundary** | Render-time throw in a sub-component | Isolated retry | `SectionErrorBoundary` from `@/components/common` |
+| 4 | **Page boundary** | Render-time throw on a whole page | Whole route | `CreatorPageErrorBoundary`, `AppErrorBoundary` |
+| 5 | **Tx surface** | On-chain trade write failure | Detail-oriented | `TransactionRetryNotice` + `TransactionFailureDrawer` |
+
+**Plus one always-on overlay** for a precondition state:
+
+| # | Mode | Trigger | Audience | Component |
+| --- | ------------------ | ----------------------------- | ----------------- | -------------------------------------------------- |
+| 6 | **Network banner** | Connected wallet, wrong chain | Persistent notice | `NetworkMismatchBanner` from `@/components/common` |
+
+---
+
+## Decision Flowchart
+
+Walk this top to bottom. The first matching branch wins.
+
+```
+Did the error come from a user-initiated write (buy, sell, enroll, claim, …)?
+├── YES → Mode 1 (Toast) — see "Mode 1: Toasts"
+│ Special: On-chain writes → also open Mode 5 drawer for detail
+└── NO → Did it come from a useQuery that blocks the page?
+ ├── YES → Mode 2 (Inline state) — see "Mode 2: Inline"
+ └── NO → Did something throw while rendering JSX?
+ ├── YES inside a sub-component →
+ │ Mode 3 (SectionErrorBoundary)
+ ├── YES at the route level →
+ │ Mode 4 (Page boundary)
+ └── NO → Re-check the trigger; you may have an
+ unhandled case — default to Mode 4 (the last
+ line of defense is `AppErrorBoundary`).
+
+Network mismatch? → Mode 6 banner (always-on; renders nothing when healthy).
+```
+
+> **Cross-link.** The same boundary vs inline split is described from the
+> loading-state angle in
+> [State Management → 3. Error Architecture Strategy](./state-management.md#3-error-architecture-strategy-boundary-vs-inline-states).
+> This document is the full convention; that section is the executive summary.
+
+---
+
+## Mode 1 — Toasts for Mutation Errors
+
+**Use when:**
+
+- The failure came from a user-initiated write (buy, sell, course enroll,
+ profile update, share, copy).
+- The page can still render usefully without retrying.
+- One short line of feedback is enough — the user needs to know "this
+ didn't work" and either retry or change input.
+
+**Don't use when:**
+
+- The failure blocks the primary purpose of the screen (use Mode 2).
+- The failure contains field-level validation detail that must attach to a
+ specific input (use Mode 2 inline errors with `apiError.response?.errors`).
+- You need to retry automatically — toasts disappear, they don't retry.
+
+### Pattern: `useMutation.onError`
+
+Cast the error to `ApiError` and branch on `status`. The numeric scale is
+documented in
+[Error Handling in Hooks → Distinguishing Error Types](./error-handling-in-hooks.md#distinguishing-error-types);
+here is the consolidated decision:
+
+```ts
+// src/hooks/useBuyCreatorKey.ts
+import { useMutation, useQueryClient } from '@tanstack/react-query';
+import { ApiError } from '@/services/api.service';
+import showToast from '@/utils/toast.util';
+import { queryKeys } from '@/lib/queryKeys';
+import { creatorKeysService } from '@/services/creatorKeys.service';
+
+export function useBuyCreatorKey() {
+ const queryClient = useQueryClient();
+
+ return useMutation({
+ mutationFn: ({
+ creatorId,
+ amount,
+ }: {
+ creatorId: string;
+ amount: number;
+ }) => creatorKeysService.buyKey(creatorId, amount),
+
+ onError: error => {
+ const apiError = error as ApiError;
+
+ // 1. Network failure — user is offline / server unreachable
+ if (apiError.status === 0) {
+ showToast.error(
+ 'Network error. Check your connection and try again.'
+ );
+ return;
+ }
+
+ // 2. Server failure — not the user's fault; generic + retry
+ if (apiError.status >= 500) {
+ showToast.error(
+ 'The server ran into a problem. Please try again shortly.'
+ );
+ return;
+ }
+
+ // 3. Validation — surface the first field error if present
+ if (apiError.status === 422 && apiError.response?.errors?.length) {
+ showToast.error(apiError.response.errors[0].message);
+ return;
+ }
+
+ // 4. Other 4xx — API message is safe for the user
+ showToast.error(apiError.message);
+ },
+
+ onSuccess: (_, { creatorId }) => {
+ queryClient.invalidateQueries({
+ queryKey: queryKeys.creators.detail(creatorId),
+ });
+ queryClient.invalidateQueries({ queryKey: queryKeys.wallet.all });
+ showToast.success('Key purchased successfully!');
+ },
+ });
+}
+```
+
+### Pattern: User rejection (wallet signature)
+
+Wallet signatures can be rejected by the user mid-flow. Detect this with
+the shared helper and skip the noisy generic toast:
+
+```ts
+// src/hooks/useWalletConnection.ts (excerpt)
+import { getSignatureErrorMessage } from '@/utils/errorHandling.utils';
+import showToast from '@/utils/toast.util';
+
+onError: error => {
+ showToast.error(getSignatureErrorMessage(error));
+ // getSignatureErrorMessage returns either:
+ // - WALLET_ERROR_COPY.SIGNATURE_REJECTED (user clicked "Cancel")
+ // - WALLET_ERROR_COPY.SIGNATURE_FAILED (other wallet-side failure)
+};
+```
+
+`getSignatureErrorMessage` is implemented in
+[`src/utils/errorHandling.utils.ts`](./../src/utils/errorHandling.utils.ts)
+and detects the EIP-1193 code `4001`, ethers' `ACTION_REJECTED`, and the
+common message fragments "user rejected" / "declined" / "cancelled".
+
+### Pattern: Off-chain mutation that should NOT use a drawer
+
+Copy-to-clipboard, share-to-Twitter, follow a creator — all of these are
+writes that have no chain side effects. Just toast:
+
+```ts
+// Excerpt from CreatorProfileHeader
+const handleShare = async () => {
+ try {
+ await navigator.clipboard.writeText(profileUrl);
+ showToast.success('Profile link copied to clipboard!');
+ } catch {
+ showToast.error('Could not copy the profile link. Please try again.');
+ }
+};
+```
+
+---
+
+## Mode 2 — Inline Error State for Blocking Query Failures
+
+**Use when:**
+
+- The query is the primary content of the page (e.g. creator profile header).
+- Without the data, the screen is empty; there is nothing else for the user
+ to do here.
+- You want the user to retry without leaving the page — wire `refetch` from
+ React Query.
+
+**Don't use when:**
+
+- The query is enriching a page that can render something else (use Mode 3).
+- The failure came from a mutation (use Mode 1).
+
+### Pattern: Canonical shared component
+
+`CreatorProfileErrorState` is the canonical inline error component. It
+renders a marketplace-styled card with an icon, a message, and an optional
+retry button.
+
+```tsx
+// In a creator profile section
+import { useCreatorProfile } from '@/hooks/useCreatorProfile';
+import CreatorProfileErrorState from '@/components/common/CreatorProfileErrorState';
+import { ApiError } from '@/services/api.service';
+
+function CreatorHeader({ creatorId }: { creatorId: string }) {
+ const { data, isLoading, isError, error, refetch } =
+ useCreatorProfile(creatorId);
+
+ if (isLoading) return void refetch()}
+ isRetrying={
+ false /* wire from your query's isFetching if you want */
+ }
+ title="Unable to load this creator profile"
+ />
+ );
+ }
+
+ return
+ {apiError.status >= 500
+ ? 'Unable to load holdings. Please try again later.'
+ : apiError.message}
+
+
+
+ );
+}
+```
+
+### Inline vs. throw-to-boundary — the rule
+
+> If the failure should leave the rest of the page interactive → render an
+> **inline** state. If it means the route as a whole cannot be useful → throw
+> the error and let the page-level boundary catch it.
+
+Concretely:
+
+- A creator list failing inside the marketplace page? **Inline.** The hero,
+ filters, and holdings are still useful.
+- The creator profile header failing on `/creator/:id`? **Throw** →
+ `CreatorPageErrorBoundary` renders a "Creator not found" or
+ "could not load" page-level state and a back-link.
+
+---
+
+## Mode 3 — Section Error Boundary (Render Falls Here)
+
+**Use when:**
+
+- A sub-component (tab body, sidebar, list section) can throw during render
+ — e.g. it consumes data that is undefined when the parent didn't gate it.
+- A failure in **this section** should not crash the whole page.
+- The user should be able to retry the section without a full reload.
+
+**Don't use when:**
+
+- The error is a query failure (React Query surfaces it via `isError` —
+ branch in the component, don't throw).
+- The error is from an on-chain mutation (use Mode 5).
+
+### Pattern: Wrap any sub-tree that might throw
+
+```tsx
+import SectionErrorBoundary from '@/components/common/SectionErrorBoundary';
+
+// In LandingPage
+
+ ;
+```
+
+The retry button on the fallback resets the boundary's internal error
+state; it does **not** re-fire the underlying `useQuery`. If you need a
+network retry, combine the boundary with a query that has `enabled` tied
+to a "retry counter" `useState` and bump it inside the retry handler.
+
+### Pair with `throwOnError`
+
+If you want React Query to throw a render-time exception (so the boundary
+catches it) instead of branching on `isError` inside the component, opt in
+on the query:
+
+```ts
+useQuery({
+ queryKey: queryKeys.creators.detail(id),
+ queryFn: () => courseService.getById(id),
+ throwOnError: error => {
+ const api = error as ApiError;
+ // 4xx: render inline; 5xx: bubble to boundary
+ return api.status >= 500;
+ },
+});
+```
+
+See [Error Handling in Hooks → SectionErrorBoundary](./error-handling-in-hooks.md#use-sectionerrorboundary-when)
+for the full reasoning.
+
+---
+
+## Mode 4 — Page-Level Error Boundaries
+
+There are two nested page boundaries; pick the **most specific** one that
+fits the route.
+
+### `CreatorPageErrorBoundary` — creator routes
+
+Scoped to `/creator/:id` and any other creator detail route. When a creator
+page throws, this catches it and renders a fallback with a "back to
+creators" link. It special-cases `ApiError` with `status === 404` to render
+a "Creator not found" message instead of a generic failure.
+
+```tsx
+// src/pages/CreatorDetailPage.tsx
+import CreatorPageErrorBoundary from '@/components/common/CreatorPageErrorBoundary';
+
+export default function CreatorDetailPage() {
+ const { id } = useParams<{ id: string }>();
+ const { data, isLoading, error } = useCreatorDetail(id ?? '');
+
+ if (!data && !isLoading) {
+ throw new ApiError('Creator not found', 404);
+ }
+ if (error) {
+ throw error; // → CreatorPageErrorBoundary
+ }
+
+ return {routes} ;
+```
+
+### `AppErrorBoundary` — last line of defense
+
+Mounted once in [`src/App.tsx`](./../src/App.tsx) around the router. When
+something throws that isn't caught by a more specific boundary, this is
+the last chance before React would otherwise unmount the entire tree. The
+fallback offers a **full page reload** rather than resetting local state —
+the rationale is documented in the component's source comment.
+
+Reach: anything that escapes a `SectionErrorBoundary` or
+`CreatorPageErrorBoundary` will land here.
+
+---
+
+## Mode 5 — Transaction Failure Surfaces
+
+Buy / sell / claim trades have **two** surfaces: an inline
+`TransactionRetryNotice` so the user sees a persistent recovery prompt,
+and a modal `TransactionFailureDrawer` for full diagnostic detail.
+
+### When to use both together
+
+A failed trade should:
+
+1. Show a `TransactionRetryNotice` in place of the trade action area —
+ it stays visible until the user retries or dismisses.
+2. Open a `TransactionFailureDrawer` so the user can copy the error code
+ or transaction hash for support.
+
+```tsx
+// src/components/common/CreatorCard.tsx (excerpt)
+import TransactionRetryNotice from '@/components/common/TransactionRetryNotice';
+import TransactionFailureDrawer from '@/components/common/TransactionFailureDrawer';
+import type { TransactionFailureDetails } from '@/components/common/TransactionFailureDrawer';
+
+const [failure, setFailure] = useState(null);
+
+const handleTrade = async (amount: number) => {
+ try {
+ await buyKey({ creatorId, amount });
+ } catch (err) {
+ const apiError = err as ApiError;
+ setFailure({
+ errorMessage: apiError.message,
+ errorCode: apiError.response?.code,
+ txHash: undefined, // chain-specific; pass when available
+ timestamp: Date.now(),
+ developerDetails: apiError.response,
+ });
+ }
+};
+
+return (
+ <>
+ {failure && (
+ <>
+ {
+ setFailure(null);
+ handleTrade(lastAmount);
+ }}
+ />
+ {
+ setFailure(null);
+ handleTrade(lastAmount);
+ }}
+ onDismiss={() => setFailure(null)}
+ />
+
+ )}
+
+);
+```
+
+`TransactionFailureDetails`:
+
+| Field | Type | Purpose |
+| ------------------ | -------------------------- | ---------------------------------------------- |
+| `errorMessage` | `string` (required) | User-facing message displayed in the drawer |
+| `txHash` | `string?` | On-chain hash for support; copy-to-clipboard |
+| `errorCode` | `string?` | Machine code (e.g. `INSUFFICIENT_BALANCE`) |
+| `timestamp` | `number?` | Unix ms; rendered via `formatTimestampTooltip` |
+| `developerDetails` | `Record?` | Hidden behind a `` toggle for devs |
+
+See [`src/components/common/TransactionFailureDrawer.tsx`](./../src/components/common/TransactionFailureDrawer.tsx)
+for the component contract.
+
+### When to NOT use the drawer
+
+If the action is not on-chain (share, copy, follow) — toast only. The
+drawer exists to expose blockchain-detail information; if there is no
+chain context, it adds noise.
+
+---
+
+## Mode 6 — Network Mismatch Banner
+
+`NetworkMismatchBanner` is **always-on**: it reads from
+`useNetworkMismatch()` and returns `null` when the wallet is on the
+correct network. Mount it once in any layout where users can initiate
+trades; it renders nothing in the happy path.
+
+```tsx
+// Wherever the user can trade
+
+
+```
+
+This is **not** an error per se — it's a precondition warning. Do **not**
+also toast "wrong network" on top of this banner; the banner is the
+canonical surface.
+
+---
+
+## Branching on `ApiError.status` — Consolidated Cheat Sheet
+
+The same numeric scale drives every mode. Source:
+[`src/services/api.service.ts`](./../src/services/api.service.ts) →
+[`BaseApiService.handleError`](./../src/services/api.service.ts).
+

+| `400` | Malformed request | `apiError.message` (safe) | `apiError.message` | `AppErrorBoundary` |
+| `401` | Session expired | (interceptor handles — auto-refresh, redirect to `/login`) | n/a | n/a |
+| `403` | Insufficient permissions | `apiError.message` | "You don't have access to this." | `AppErrorBoundary` |
+| `404` | Resource not found | `apiError.message` | "Not found." | `CreatorPageErrorBoundary` (404 special-cases) |
+| `422` | Validation failure | `apiError.response.errors[0].message` (first field error) | Map every `response.errors[i]` to its input | `AppErrorBoundary` |
+| `429` | Rate limited | "Too many requests. Please wait a moment and retry." | "Rate limited. Try again shortly." | `AppErrorBoundary` |
+| `>= 500` | Server error | "The server ran into a problem. Please try again shortly." | "Unable to load this. Try again later." | Section-level (skeleton→empty→relies on inline) |

+
+## Adding a New Error Type to the Classification System
+
+The codebase has **two** classification helpers that capture domain
+specifics. Pick the one that matches your domain; do not invent a new
+helper unless neither fits.
+
+### 1. Wallet & signature errors → extend `WALLET_ERROR_COPY`
+
+File: [`src/utils/errorHandling.utils.ts`](./../src/utils/errorHandling.utils.ts).
+
+Centralized map of wallet-and-signature messages, plus detection helpers:
+
+```ts
+export const WALLET_ERROR_COPY = {
+ SIGNATURE_REJECTED:
+ "Signature request was declined. Please try again when you're ready to confirm.",
+ SIGNATURE_FAILED:
+ 'The signature request failed. Please ensure your wallet is unlocked and try again.',
+ GENERIC_TRANSACTION_FAILED:
+ 'Transaction failed. Please check your balance or connection and try again.',
+};
+
+export function isUserRejection(error: unknown): boolean {
+ /* … */
+}
+export function getSignatureErrorMessage(error: unknown): string {
+ /* … */
+}
+```
+
+**To add a new wallet error type:**
+
+1. Append a new key to `WALLET_ERROR_COPY` with a sentence that states the
+ cause and the next step.
+2. If the detector matters, extend `isUserRejection`-style recognition in
+ a new exported predicate (`isRateLimited(error)`, `isChainSwitchRequired(error)`).
+3. Wire the predicate + key into the calling hook's `onError` — usually
+ by extending `getSignatureErrorMessage` or introducing a sibling
+ `getWalletErrorMessage` if the surface is broader than signatures.
+4. Add a Vitest unit test under
+ `src/utils/__tests__/errorHandling.utils.test.ts` that pins the new
+ copy and predicate behavior.
+
+### 2. Pre-action disabled reasons → extend the typed helper
+
+File: [`src/utils/claimActionDisabledReason.ts`](./../src/utils/claimActionDisabledReason.ts).
+
+Pattern: a **closed union** of reason keys + a **single `Record`** that
+maps each key to a standardized copy. This pattern is reused for other
+disabled-reason surfaces (see `BuyActionHelperText` and
+`ClaimActionHelperText` documentation).
+
+```ts
+export type ClaimActionDisabledReasonKey =
+ | 'wallet_not_connected'
+ | 'no_claimable_rewards'
+ | 'claim_in_progress'
+ | 'network_mismatch'
+ | 'insufficient_gas'
+ | 'unknown';
+
+const CLAIM_ACTION_DISABLED_REASON_TEXT: Record<
+ ClaimActionDisabledReasonKey,
+ string
+> = {
+ // Every entry follows the same shape:
+ // "{Action} is unavailable because {cause}. {Next step}."
+ wallet_not_connected:
+ 'Claim is unavailable because your wallet is not connected. Connect your wallet to continue.',
+ // …
+};
+
+export const getClaimActionDisabledReasonText = (
+ reason: ClaimActionDisabledReasonKey
+): string => CLAIM_ACTION_DISABLED_REASON_TEXT[reason];
+```
+
+**To add a new disabled reason:**
+
+1. Append the new key to the union — **don't** fall back to `unknown`
+ silently; force every caller to make a decision.
+2. Add a matching entry to `CLAIM_ACTION_DISABLED_REASON_TEXT` using the
+ "{Action} is unavailable because {cause}. {Next step}." template so
+ tones stay consistent.
+3. Compute the new key at the call site (the component that evaluates
+ pre-conditions) and pass it to `getClaimActionDisabledReasonText`.
+4. Extend
+ `src/utils/__tests__/claimActionDisabledReason.test.ts` to cover the
+ new key.
+
+### 3. When neither helper fits
+
+If your error surface is genuinely new (e.g. diverging-chain detection,
+on-chain simulation errors), create a new sibling helper in
+`src/utils/ErrorHandling.utils.ts` following the same shape:
+
+1. **Closed key union** — TypeScript exhaustiveness forces callers to
+ pick a copy.
+2. **One Record/Map** that owns _all_ English copy — no copy scattered
+ across components.
+3. **Pure functions** — no React, no hooks, no side effects. Easy to
+ unit-test.
+4. **Side-by-side tests** — colocated unit test in
+ `src/utils/__tests__/`.
+
+Do not duplicate copy inline in components; always go through a typed
+helper so future copy edits stay coherent.
+
+---
+
+## Shared Error State Components — Reference
+
+| Component | Mode | Purpose | Key props |
+| -------------------------------------------------- | ---- | --------------------------------------------------- | ------------------------------------------------------------------------- |
+| `showToast` (`@/utils/toast.util`) | 1 | Mutation feedback (success, error, loading, tx) | `showToast.{success,error,loading,transactionSuccess}(message, options?)` |
+| `CreatorProfileErrorState` (`@/components/common`) | 2 | Canonical inline error card for creator profile | `error?, onRetry?, isRetrying?, title?, message?` |
+| `SectionErrorBoundary` (`@/components/common`) | 3 | Catches sub-tree render throws with retry | `sectionName?, minHeight?, className?` |
+| `CreatorPageErrorBoundary` (`@/components/common`) | 4 | Catches creator-route render throws | none (wraps ``) |
+| `AppErrorBoundary` (`@/components/common`) | 4 | App-wide last-line-of-defense; full reload on retry | none (wraps ``) |
+| `TransactionRetryNotice` (`@/components/common`) | 5 | Persistent inline retry banner for failed trades | `title?, message, onRetry, retryLabel?, disabled?, className?` |
+| `TransactionFailureDrawer` (`@/components/common`) | 5 | Modal with error code, hash, and developer details | `open, onOpenChange?, failureDetails, onRetry?, onDismiss?` |
+| `NetworkMismatchBanner` (`@/components/common`) | 6 | Persistent "wrong network" warning | `className?` |
+
+For accessible state components (skeletons, empty states), see
+[Adding a Page and Data Fetching](./adding-page-and-data-fetching.md)
+and [Shared Components](./shared-components.md).
+
+---
+
+## Worked Examples
+
+### Example A — Marketplace search list (read failure → Mode 2)
+
+The creator list inside the marketplace is critical content, so a query
+failure renders an inline state with retry. The rest of the page
+(hero, holdings, footer) stays interactive.
+
+```tsx
+// src/pages/LandingPage.tsx (excerpt)
+const { data: creators, isError, error, refetch } = useCreatorList();
+
+if (isError) {
+ const apiError = error as ApiError;
+ return (
+
+ Couldn't load the creator list
+
+ {apiError.status >= 500
+ ? 'Something went wrong on our end. Please try again.'
+ : apiError.message}
+
+
+
+ );
+}
+
+return
+
+ );
+}
+```
+
+### Example C — Buy flow (mutation failure → Mode 1 + Mode 5)
+
+A trade mutation has both the prompt (toast), the persistent retry
+banner, and the detail drawer:
+
+```tsx
+// src/components/common/CreatorCard.tsx (excerpt)
+const buy = useBuyCreatorKey();
+
+const handleBuy = async (amount: number) => {
+ try {
+ await buy.mutateAsync({ creatorId, amount });
+ } catch (err) {
+ const apiError = err as ApiError;
+
+ // Mode 1: quick prompt
+ showToast.error(
+ apiError.status === 0
+ ? 'Network error. Check your connection.'
+ : apiError.message
+ );
+
+ // Mode 5: persistent banner + drawer for support detail
+ setFailure({
+ errorMessage: apiError.message,
+ errorCode: apiError.response?.code,
+ timestamp: Date.now(),
+ });
+ }
+};
+```
+
+---
+
+## Quick Reference
+
+| Question | Answer |
+| ----------------------------------------------------- | ----------------------------------------------------- |
+| Failure from a button click? | Toast (Mode 1), add drawer for on-chain trades |
+| Failure from `useQuery` that **is** the page? | Throw → Page boundary (Mode 4) |
+| Failure from `useQuery` that **enriches** the page? | Inline state with `refetch` (Mode 2) |
+| Component throws during render (not a query error)? | Wrap in `SectionErrorBoundary` (Mode 3) |
+| Wallet is connected but wrong chain? | `NetworkMismatchBanner` (Mode 6) |
+| User clicked "Cancel" on the wallet signature prompt? | `getSignatureErrorMessage` (Mode 1, specialised copy) |
+| New kind of wallet error? | Extend `WALLET_ERROR_COPY` |
+| New pre-action disabled reason? | Extend `ClaimActionDisabledReasonKey` + lookup |

+# Error Handling in React Query Hooks
+
+This guide documents the standard pattern for handling API errors in React Query hooks across this codebase. Follow it when writing new `useQuery` or `useMutation` hooks so error behavior is consistent and predictable for users.
+
+---
+
+## How Errors Flow In
+
+All HTTP requests go through the service layer (`src/services/`), which extends `BaseApiService`. The `handleError` method on that base class normalises every failure into an `ApiError` before it reaches the hook:
+
+| Raw failure | What you receive |
+| ------------------------------------- | ------------------------------------------------------ |
+| HTTP response with an error status | `ApiError(message, httpStatus, responseBody)` |
+| Request sent but no response received | `ApiError('Network error - check your connection', 0)` |
+| Unexpected non-HTTP exception | `ApiError(error.message, 500)` |
+
+One important exception: **401 + `TOKEN_EXPIRED`** is handled transparently by the Axios interceptor in `BaseApiService`. The interceptor silently retries the original request after refreshing the access token. If the refresh also fails the user is redirected to `/login`; the hook never sees this error.
+
+---
+
+## The `ApiError` Shape
+
+```ts
+// src/services/api.service.ts
+class ApiError extends Error {
+ status: number; // HTTP status code; 0 means no network response
+ response?: {
+ success: false;
+ message: string;
+ code?: string; // machine-readable code from the API, e.g. "INSUFFICIENT_BALANCE"
+ errors?: Array<{
+ field?: string; // present on 422 validation failures
+ message: string;
+ }>;
+ };
+}
+```
+
+Always cast the error to `ApiError` before inspecting it:
+
+```ts
+import { ApiError } from '@/services/api.service';
+
+onError: error => {
+ const apiError = error as ApiError;
+ console.log(apiError.status); // 0, 400, 403, 422, 500 …
+ console.log(apiError.message); // human-readable message from the API
+ console.log(apiError.response?.errors); // field-level details on 422
+};
+```
+
+---
+
+## Distinguishing Error Types
+
+### Network errors (`status === 0`)
+
+No response was received — the user is offline, the server is unreachable, or a timeout occurred. The user cannot fix the request payload; they need to retry later.
+
+```ts
+if (apiError.status === 0) {
+ showToast.error('Network error. Check your connection and try again.');
+ return;
+}
+```
+
+### 4xx — Client errors
+
+The request was received but rejected because of something the client sent. The message from the API is usually safe to show to the user.
+
+| Status | Cause | Typical UI response |
+| ------ | ------------------------ | ---------------------------------------------------- |
+| 400 | Malformed request | Toast with `apiError.message` |
+| 401 | Session expired | Auto-handled by the interceptor |
+| 403 | Insufficient permissions | Inline error or redirect |
+| 404 | Resource not found | Inline error state |
+| 422 | Validation failure | Inline field errors from `apiError.response?.errors` |
+| 429 | Rate limited | Toast with retry suggestion |
+
+### 5xx — Server errors
+
+The API itself failed. The user cannot fix the payload; they can only retry after the server recovers. Avoid showing raw server messages — use a generic fallback instead.
+
+```ts
+if (apiError.status >= 500) {
+ showToast.error('The server ran into a problem. Please try again shortly.');
+ return;
+}
+```
+
+---
+
+## Deciding: Toast vs. Inline Error vs. Error Boundary
+
+### Use a toast when
+
+- The failure came from a **user-initiated action** (mutation): buying a key, submitting a form, enrolling in a course.
+- The error **does not block the current view** — the page can still render usefully.
+- The fix is to retry or change input: one line of feedback is enough.
+
+```ts
+onError: error => {
+ const apiError = error as ApiError;
+ showToast.error(
+ apiError.status >= 500
+ ? 'Something went wrong. Try again.'
+ : apiError.message
+ );
+};
+```
+
+### Use an inline error state when
+
+- The error **blocks the primary purpose of the screen** — for example, the creator list failed to load so the page is empty.
+- The error contains **field-level detail** (422) that needs to map to specific form inputs.
+- The user needs to take **corrective action** (fix a field, switch networks) before retrying makes sense.
+
+```tsx
+const { data, isError, error } = useCreatorKeys(creatorId);
+
+if (isError) {
+ const apiError = error as ApiError;
+ return (
+
+ {apiError.status >= 500
+ ? 'Unable to load data. Please try again later.'
+ : apiError.message}
+
+ );
+}
+```
+
+### Use `SectionErrorBoundary` when
+
+- A **component throws during render**, not from an API call.
+- You want to **isolate a section** so one broken widget does not crash the whole page.
+- React Query's `throwOnError` option is enabled on a query.
+
+```tsx
+import SectionErrorBoundary from '@/components/common/SectionErrorBoundary';
+
+
+ ;
+```
+
+`SectionErrorBoundary` renders a retry button that resets its own error state. Use it as a safety net around sections that fetch and render data together.
+
+---
+
+## `useQuery` Pattern
+
+React Query v5 removed the `onError` callback from `useQuery`. Errors surface through `isError` and `error` in the component. Keep the hook thin and handle the error at the call site:
+
+```ts
+// src/hooks/useCreatorProfile.ts
+import { useQuery } from '@tanstack/react-query';
+import { creatorService } from '@/services/creator.service';
+
+export function useCreatorProfile(creatorId: string) {
+ return useQuery({
+ queryKey: ['creator-profile', creatorId],
+ queryFn: () => creatorService.getProfile(creatorId),
+ staleTime: 30_000,
+ });
+}
+```
+
+```tsx
+// In the component
+import { ApiError } from '@/services/api.service';
+import { useCreatorProfile } from '@/hooks/useCreatorProfile';
+
+function CreatorProfileSection({ creatorId }: { creatorId: string }) {
+ const { data, isLoading, isError, error } = useCreatorProfile(creatorId);
+
+ if (isLoading) return
+ {apiError.status >= 500
+ ? 'Unable to load keys right now. Please try again later.'
+ : apiError.message}
+
+
+ );
+ }
+
+ return (
+ // SectionErrorBoundary catches any render-time throws inside KeysList
+
+ buyKey({ creatorId, amount })}
+ isBuying={isPending}
+ />
+
+ );
+}
+```
+
+---
+
+## Quick Reference
+
+| Condition | Check | UI response |
+| ------------------- | ------------------------------- | ------------------------------------------------------------ |
+| No network response | `apiError.status === 0` | Toast: "Network error. Check your connection." |
+| Server error | `apiError.status >= 500` | Toast: generic "something went wrong" message |
+| Validation failure | `apiError.status === 422` | Toast or inline: first item from `apiError.response?.errors` |
+| Other 4xx | `apiError.status >= 400` | Toast or inline: `apiError.message` (safe from the API) |
+| Read query fails | `isError === true` in component | Inline error state replacing the content area |
+| Render throws | Component boundary | Wrap with `` |

+# Editing Marketing Page Copy
+
+This guide is for non-technical contributors who want to suggest changes to the
+marketing page copy. You can edit the text directly on GitHub and open a pull
+request — no local development environment is required.
+
+## Where the copy lives
+
+All marketing page copy is in a single file:
+
+**`src/pages/MarketingPage.tsx`**
+
+The page is a single React component. Each visible section is a block of JSX
+with inline text. Use the table below to find the section you want to change.
+
+| Visible section on the page | Location in `MarketingPage.tsx` | What to look for |
+| ------------------------------- | ----------------------------------------- | ------------------------------------------------------------------------------ |
+| Page title ("Access Layer") | Hero / Title | `` with the `Access Layer` heading |
+| Intro paragraph under the title | Intro | First `
` after the title |
+| **The idea** | `{/* The idea */}` section | Eyebrow text `The idea` and the two body paragraphs below it |
+| **How it works** | `{/* How it works */}` section | Eyebrow text `How it works` and the two body paragraphs below it |
+| **What makes it different** | `{/* What makes it different */}` section | Eyebrow text `What makes it different` and the body paragraph below it |
+| **Built on Stellar** | `{/* Built on Stellar */}` section | Eyebrow text `Built on Stellar` and the two body paragraphs below it |
+| **Join the community** | `{/* Community */}` section | Eyebrow text `Join the community`, the subtitle, and the GitHub/Telegram links |
+| Footer | `{/* Footer */}` section | Logo label and the "Built on Stellar" tagline |
+
+Section eyebrows use this pattern — a short uppercase label in blue:
+
+```tsx
+
+ The idea

+```

+/**
+ * Integration test for holdings entry count after buy/sell sequence (#TBD).
+ *
+ * The holdings list should add an entry when a buy confirms for a new creator
+ * and remove it when all keys for that creator are sold. Additional keys for
+ * an existing creator must not produce a duplicate entry.
+ *
+ * Held positions are derived from the API response:
+ * index 0 → featuredHoldings (mutable via TradeDialog, starts at 3)
+ * index 1+ → DEMO_HELD_KEY_QUANTITIES (fixed per session)
+ *
+ * Flow (2 creators returned by the API):
+ * 1. Initial: featuredHoldings=3 (Creator A) + 2 keys (Creator B) → 2 entries
+ * 2. Sell all 3 keys of Creator A → 1 entry (only Creator B)
+ * 3. Buy 1 key of Creator A → 2 entries (A re-added, B still present)
+ * 4. Buy 2 more keys of Creator A → still 2 entries (no duplicate)
+ * 5. Sell all 3 keys of Creator A → 1 entry (only Creator B again)
+ *
+ * Acceptance criteria covered:
+ * - Entry added when a buy confirms for a new creator (step 3)
+ * - Entry not duplicated when additional keys are bought (step 4)
+ * - Entry removed when all keys for a creator are sold (steps 2, 5)
+ * - Entry count correct after each state change (all steps)

+
+## Public vs auth-protected routes
+
+There is **no existing `RequireAuth` / `ProtectedRoute` wrapper** in the codebase yet. Every route registered today is public. When a feature needs auth gating, follow the pattern below — and ship the wrapper component with that feature, since the client doesn't have a standalone auth-guard component yet.
+
+### Recommended pattern
+
+1. Create a small wrapper component, conventionally `src/components/auth/RequireAuth.tsx` (create the `auth/` subfolder if it doesn't exist yet).
+2. Inside the wrapper, check the appropriate auth state — wagmi's `useAccount` for wallet-gated flows, or `authService.isAuthenticated()` for email/login-gated flows.
+3. While the state is resolving, render a lightweight placeholder (the existing `PendingOnboardingPlaceholder` makes a good model).
+4. If unauthenticated, render a redirect or a connect-wallet CTA — do **not** render the protected page.
+5. Wrap the protected page's `element` with the wrapper inside `App.tsx`.
+
+```tsx
+// src/components/auth/RequireAuth.tsx
+import type { ReactNode } from 'react';
+import { useAccount } from 'wagmi';
+import { Navigate, useLocation } from 'react-router';
+import PendingOnboardingPlaceholder from '@/components/common/PendingOnboardingPlaceholder';
+
+interface RequireAuthProps {
+ children: ReactNode;
+}
+
+export default function RequireAuth({ children }: RequireAuthProps) {
+ const { isConnected, isConnecting } = useAccount();
+ const location = useLocation();
+
+ // Show the placeholder while a fresh wallet connection is in flight
+ // so the user isn't redirected to "/" mid-connect. Once it resolves,
+ // isConnected flips to true and we render the protected page below.
+ // Note: isReconnecting is intentionally NOT in this branch — a
+ // reconnect of a prior session keeps the user authenticated, so
+ // rendering the protected page during a reconnect is fine.
+ if (isConnecting) {
+ return :
+ element: (
+
+
+ ),
+ },
+ { path: '*', element: ` is not currently mounted above ``. Any wagmi hook — including `useAccount` inside `RequireAuth` — will throw at runtime because the `WagmiProvider` context is missing. Wiring `` here is an app-level change and should be tracked separately; reference the tracking issue in your route PR description rather than embedding the wiring fix in your route PR.
+2. **Wagmi has a transient `isConnecting` state** while a fresh wallet handshake is in flight. During this window `isConnected` is `false`, but redirecting the user mid-connect would bounce them away. The example above handles this by rendering `PendingOnboardingPlaceholder` for the `isConnecting` branch — copy that pattern verbatim. (Note: `isReconnecting` is _not_ included in that branch — a reconnect of a prior, already-authenticated session keeps the user authenticated, so rendering the protected page during a reconnect is fine and avoids a UX flash.)
+
+If your guard only uses `authService.isAuthenticated()` (no wagmi hooks), neither caveat applies — the helper reads `localStorage` directly.
+
+---
+
+## Worked example — adding a new public page
+
+This walks a contributor end-to-end through adding `AboutPage` at `/about`. The page is public, so no `RequireAuth` wrapper is involved.
+
+### 1. Create the page component
+
+Add a new file at `src/pages/AboutPage.tsx`:
+
+```tsx
+// src/pages/AboutPage.tsx
+import { Link } from 'react-router';
+import { Button } from '@/components/ui/button';
+
+export default function AboutPage() {
+ return (
+
+
+ About Access Layer
+
+
+ Access Layer is a Stellar-native creator keys marketplace built on
+ the open AccessLayer protocol.
+
+
+
+
+
+
+ );
+}
+```
+
+### 2. Register the route
+
+Add the import and a new entry to the router array in `src/App.tsx`:
+
+```tsx
+// src/App.tsx
+import HomePage from './pages/HomePage';
+import NotFoundPage from './pages/NotFoundPage';
+import AboutPage from './pages/AboutPage'; // ← added
+
+const router = createBrowserRouter([
+ { path: '/', element: .service.ts` | `wallet.service.ts` |
+| Class name | `Service` | `WalletService` |
+| Exported singleton | `Service` | `walletService` |
+
+Every service class **extends `BaseApiService`** from `api.service.ts`, which provides:
+
+- A pre-configured Axios instance (`this.api`) pointing at `VITE_BACKEND_URL`
+- Automatic token refresh on `401 TOKEN_EXPIRED` responses
+- A shared `handleError(error)` method that normalises any thrown value to `ApiError`
+
+---
+
+## Error handling
+
+Every service method wraps its Axios call in a `try/catch` and re-throws via `this.handleError`:
+
+```ts
+async getWalletHoldings(address: string): Promise {
+ try {
+ const response = await this.api.get>(
+ `/wallets/${address}/holdings`
+ );
+ return response.data.data;
+ } catch (error) {
+ throw this.handleError(error);
+ }
+}
+```
+
+`handleError` always returns an `ApiError` instance with:
+
+| Field | Type | Description |
+| ---------- | ------------------------------- | ------------------------------------------ |
+| `message` | `string` | Human-readable error message |
+| `status` | `number` | HTTP status code; `0` for network failures |
+| `response` | `APIErrorResponse \| undefined` | Full server error payload when available |
+
+Callers can check `error instanceof ApiError` and inspect `error.status` for branching logic.
+
+---
+
+## How to add a new endpoint
+
+### 1. Add the method to the relevant service file
+
+Open `src/services/.service.ts` (or create a new one if the domain is new). Add a method that:
+
+1. Calls `this.api.get/post/patch/delete`
+2. Extracts `response.data.data`
+3. Re-throws any error via `this.handleError`
+
+```ts
+// src/services/wallet.service.ts
+import { BaseApiService, type APIResponse } from './api.service';
+
+export interface Holding {
+ creatorId: string;
+ quantity: number;
+ priceStroops: number;
+}
+
+class WalletService extends BaseApiService {
+ async getHoldings(address: string): Promise {
+ try {
+ const response = await this.api.get>(
+ `/wallets/${address}/holdings`
+ );
+ return response.data.data;
+ } catch (error) {
+ throw this.handleError(error);
+ }
+ }
+}
+
+export const walletService = new WalletService();
+```
+
+### 2. Define a query key in `src/lib/queryKeys.ts`
+
+Add an entry for the new endpoint so all hooks that reference the same data use an identical cache key:
+
+```ts
+// src/lib/queryKeys.ts
+wallet: {
+ holdings: (address: string) => ['wallet', address, 'holdings'] as const,
+ // ...
+},
+```
+
+### 3. Write a React Query hook
+
+`QueryClientProvider` is already wired up in `src/providers/Web3Provider.tsx` — no setup changes needed.
+
+```ts
+// src/hooks/useWalletHoldings.ts
+import { useQuery } from '@tanstack/react-query';
+import { walletService } from '@/services/wallet.service';
+import { queryKeys } from '@/lib/queryKeys';
+
+export function useWalletHoldings(address: string | undefined) {
+ return useQuery({
+ queryKey: queryKeys.wallet.holdings(address ?? ''),
+ queryFn: () => walletService.getHoldings(address!),
+ enabled: Boolean(address),
+ });
+}
+```
+
+### 4. Consume the hook in a component
+
+```tsx
+import { useWalletHoldings } from '@/hooks/useWalletHoldings';
+
+function HoldingsList({ address }: { address: string }) {
+ const { data: holdings, isLoading, error } = useWalletHoldings(address);
+
+ if (isLoading) return Loading…
;
+ if (error) return Failed to load holdings.
;
+
+ return (
+
+ {holdings?.map(h => (
+ -
+ {h.creatorId} — {h.quantity} keys
+
+ ))}
+
+ );
+}
+```
+
+---
+
+## Worked example — full GET call
+
+The following shows a complete end-to-end flow for a `GET /wallets/:address/holdings` endpoint.
+
+### Service method
+
+```ts
+// src/services/wallet.service.ts
+import { BaseApiService, type APIResponse } from './api.service';
+
+export interface Holding {
+ creatorId: string;
+ quantity: number;
+ priceStroops: number;
+}
+
+class WalletService extends BaseApiService {
+ async getHoldings(address: string): Promise {
+ try {
+ const response = await this.api.get>(
+ `/wallets/${address}/holdings`
+ );
+ return response.data.data;
+ } catch (error) {
+ throw this.handleError(error);
+ }
+ }
+}
+
+export const walletService = new WalletService();
+```
+
+### Query key
+
+```ts
+// src/lib/queryKeys.ts (existing file — add the entry)
+wallet: {
+ holdings: (address: string) => ['wallet', address, 'holdings'] as const,
+},
+```
+
+### Hook
+
+```ts
+// src/hooks/useWalletHoldings.ts
+import { useQuery } from '@tanstack/react-query';
+import { walletService } from '@/services/wallet.service';
+import { queryKeys } from '@/lib/queryKeys';
+
+export function useWalletHoldings(address: string | undefined) {
+ return useQuery({
+ queryKey: queryKeys.wallet.holdings(address ?? ''),
+ queryFn: () => walletService.getHoldings(address!),
+ enabled: Boolean(address),
+ });
+}
+```
+
+### Component
+
+```tsx
+// Usage in any component
+import { useAccount } from 'wagmi';
+import { useWalletHoldings } from '@/hooks/useWalletHoldings';
+
+function HoldingsSummary() {
+ const { address } = useAccount();
+ const { data: holdings, isLoading, error } = useWalletHoldings(address);
+
+ if (isLoading) return Loading…
;
+ if (error) return Could not load holdings.
;
+ if (!holdings?.length) return No holdings yet.
;
+
+ return (
+
+ {holdings.map(h => (
+ -
+ {h.creatorId} — {h.quantity} keys at {h.priceStroops} stroops
+
+ ))}
+
+ );
+}
+```

+# Environment Variable Guide
+
+This guide explains how to add a new client environment variable safely and consistently in Access Layer Client.
+
+The client is built with Vite, so any value that must be available in browser code must use the `VITE_` prefix. Values without that prefix are not exposed to the client bundle.
+
+## Files involved
+
+| File | Purpose |
+| ------------------------ | ---------------------------------------------------------------------------------------------------------------- |
+| `.env.example` | Documents every supported variable and provides safe local defaults or blank optional placeholders. |
+| `src/utils/env.utils.ts` | Validates environment variables at startup with Zod and exports the typed `env` object used by application code. |
+| `.env` | Local developer overrides. This file should not be committed. |
+
+## Add a new variable
+
+1. Add the variable to `.env.example`.
+2. Add validation for the variable in `src/utils/env.utils.ts`.
+3. Pass the raw `import.meta.env` value into the `envSchema.parse(...)` call in `src/utils/env.utils.ts`.
+4. Import the validated `env` object in application code.
+5. Avoid reading `import.meta.env` directly from components, hooks, or service files.
+
+## Declaration pattern
+
+Add the new variable to `.env.example` near related settings. Use a short comment that explains what the value controls and whether it is required.
+
+```env
+# Feature flag for the creator discovery experiment. Use `true` to enable locally.
+VITE_ENABLE_CREATOR_DISCOVERY=false
+```
+
+Prefer safe development defaults when the app can run without secrets. Leave optional third-party keys blank if a contributor can work without them.
+
+## Runtime validation pattern
+
+All supported variables should be declared in `src/utils/env.utils.ts` so missing or malformed configuration is caught in one place.
+
+```ts
+const envSchema = z.object({
+ VITE_ENABLE_CREATOR_DISCOVERY: z.coerce.boolean().default(false),
+});
+
+export const env = envSchema.parse({
+ VITE_ENABLE_CREATOR_DISCOVERY: import.meta.env.VITE_ENABLE_CREATOR_DISCOVERY,
+});
+```
+
+Use the Zod type that matches how the app consumes the value:
+
+| Value type | Validation example |
+| --------------- | ----------------------------------------------- |
+| Required string | `z.string().min(1, "VITE_API_KEY is required")` |
+| Optional string | `z.string().optional()` |
+| Number | `z.coerce.number().default(84532)` |
+| Boolean flag | `z.coerce.boolean().default(false)` |
+
+If a value is required for the app to start, avoid a silent fallback. Use `.min(1, "... is required")` or another explicit validation rule so the startup error points to the missing variable.
+
+## Access pattern in application code
+
+Import `env` from the validation module and read the typed value from there:
+
+```ts
+import { env } from '@/utils/env.utils';
+
+if (env.VITE_ENABLE_CREATOR_DISCOVERY) {
+ // Render or enable the feature.
+}
+```
+
+This keeps validation, defaults, and type coercion centralized.
+
+## Anti-pattern: direct component access
+
+Do not import or read `import.meta.env` directly in components, hooks, services, or utilities outside the validation module.
+
+```tsx
+// Avoid this.
+const backendUrl = import.meta.env.VITE_BACKEND_URL;
+```
+
+Direct access bypasses schema validation, makes defaults inconsistent, and spreads environment knowledge across the app. Use `env` instead:
+
+```tsx
+import { env } from '@/utils/env.utils';
+
+const backendUrl = env.VITE_BACKEND_URL;
+```
+
+## Required vs optional checklist
+
+Use this checklist before opening a PR that adds a new variable:
+
+- The variable is listed in `.env.example`.
+- The variable has a clear comment describing its purpose.
+- Required values fail fast in `src/utils/env.utils.ts` with a useful error.
+- Optional values use `.optional()` or a safe `.default(...)`.
+- Application code reads from `env`, not `import.meta.env`.
+- The variable name starts with `VITE_` if browser code needs it.

+# Error Handling Conventions
+
+> Issue #630 — Establish the expected pattern for every error category
+> (boundary, query state, mutation feedback, transaction surface, network
+> warning) so the UI feels consistent regardless of which component rendered
+> the error.
+
+This guide is the **single source of truth** for how errors are surfaced in
+the Access Layer client. Pair it with
+[Error Handling in React Query Hooks](./error-handling-in-hooks.md) for the
+hook-side `ApiError` branching detail and
+[State Management](./state-management.md) for the
+[Error Architecture Strategy](./state-management.md#3-error-architecture-strategy-boundary-vs-inline-states)
+section that motivates the boundary/inline split.
+
+---
+
+## The Five Error Display Modes
+
+Every error in the client surfaces through **one of five modes**. Pick the
+right one based on where the error came from and what the user still needs
+to be able to do.
+
+| # | Mode | Trigger | Audience | Component (canonical) |
+| --- | -------------------- | --------------------------------------- | --------------- | ----------------------------------------------------- |
+| 1 | **Toast** | `useMutation.onError` (user action) | Glanceable | `showToast.error` from `@/utils/toast.util` |
+| 2 | **Inline state** | `useQuery` `isError` (blocking content) | Focused | `CreatorProfileErrorState`, section-level cards |
+| 3 | **Section boundary** | Render-time throw in a sub-component | Isolated retry | `SectionErrorBoundary` from `@/components/common` |
+| 4 | **Page boundary** | Render-time throw on a whole page | Whole route | `CreatorPageErrorBoundary`, `AppErrorBoundary` |
+| 5 | **Tx surface** | On-chain trade write failure | Detail-oriented | `TransactionRetryNotice` + `TransactionFailureDrawer` |
+
+**Plus one always-on overlay** for a precondition state:
+
+| # | Mode | Trigger | Audience | Component |
+| --- | ------------------ | ----------------------------- | ----------------- | -------------------------------------------------- |
+| 6 | **Network banner** | Connected wallet, wrong chain | Persistent notice | `NetworkMismatchBanner` from `@/components/common` |
+
+---
+
+## Decision Flowchart
+
+Walk this top to bottom. The first matching branch wins.
+
+```
+Did the error come from a user-initiated write (buy, sell, enroll, claim, …)?
+├── YES → Mode 1 (Toast) — see "Mode 1: Toasts"
+│ Special: On-chain writes → also open Mode 5 drawer for detail
+└── NO → Did it come from a useQuery that blocks the page?
+ ├── YES → Mode 2 (Inline state) — see "Mode 2: Inline"
+ └── NO → Did something throw while rendering JSX?
+ ├── YES inside a sub-component →
+ │ Mode 3 (SectionErrorBoundary)
+ ├── YES at the route level →
+ │ Mode 4 (Page boundary)
+ └── NO → Re-check the trigger; you may have an
+ unhandled case — default to Mode 4 (the last
+ line of defense is `AppErrorBoundary`).
+
+Network mismatch? → Mode 6 banner (always-on; renders nothing when healthy).
+```
+
+> **Cross-link.** The same boundary vs inline split is described from the
+> loading-state angle in
+> [State Management → 3. Error Architecture Strategy](./state-management.md#3-error-architecture-strategy-boundary-vs-inline-states).
+> This document is the full convention; that section is the executive summary.
+
+---
+
+## Mode 1 — Toasts for Mutation Errors
+
+**Use when:**
+
+- The failure came from a user-initiated write (buy, sell, course enroll,
+ profile update, share, copy).
+- The page can still render usefully without retrying.
+- One short line of feedback is enough — the user needs to know "this
+ didn't work" and either retry or change input.
+
+**Don't use when:**
+
+- The failure blocks the primary purpose of the screen (use Mode 2).
+- The failure contains field-level validation detail that must attach to a
+ specific input (use Mode 2 inline errors with `apiError.response?.errors`).
+- You need to retry automatically — toasts disappear, they don't retry.
+
+### Pattern: `useMutation.onError`
+
+Cast the error to `ApiError` and branch on `status`. The numeric scale is
+documented in
+[Error Handling in Hooks → Distinguishing Error Types](./error-handling-in-hooks.md#distinguishing-error-types);
+here is the consolidated decision:
+
+```ts
+// src/hooks/useBuyCreatorKey.ts
+import { useMutation, useQueryClient } from '@tanstack/react-query';
+import { ApiError } from '@/services/api.service';
+import showToast from '@/utils/toast.util';
+import { queryKeys } from '@/lib/queryKeys';
+import { creatorKeysService } from '@/services/creatorKeys.service';
+
+export function useBuyCreatorKey() {
+ const queryClient = useQueryClient();
+
+ return useMutation({
+ mutationFn: ({
+ creatorId,
+ amount,
+ }: {
+ creatorId: string;
+ amount: number;
+ }) => creatorKeysService.buyKey(creatorId, amount),
+
+ onError: error => {
+ const apiError = error as ApiError;
+
+ // 1. Network failure — user is offline / server unreachable
+ if (apiError.status === 0) {
+ showToast.error(
+ 'Network error. Check your connection and try again.'
+ );
+ return;
+ }
+
+ // 2. Server failure — not the user's fault; generic + retry
+ if (apiError.status >= 500) {
+ showToast.error(
+ 'The server ran into a problem. Please try again shortly.'
+ );
+ return;
+ }
+
+ // 3. Validation — surface the first field error if present
+ if (apiError.status === 422 && apiError.response?.errors?.length) {
+ showToast.error(apiError.response.errors[0].message);
+ return;
+ }
+
+ // 4. Other 4xx — API message is safe for the user
+ showToast.error(apiError.message);
+ },
+
+ onSuccess: (_, { creatorId }) => {
+ queryClient.invalidateQueries({
+ queryKey: queryKeys.creators.detail(creatorId),
+ });
+ queryClient.invalidateQueries({ queryKey: queryKeys.wallet.all });
+ showToast.success('Key purchased successfully!');
+ },
+ });
+}
+```
+
+### Pattern: User rejection (wallet signature)
+
+Wallet signatures can be rejected by the user mid-flow. Detect this with
+the shared helper and skip the noisy generic toast:
+
+```ts
+// src/hooks/useWalletConnection.ts (excerpt)
+import { getSignatureErrorMessage } from '@/utils/errorHandling.utils';
+import showToast from '@/utils/toast.util';
+
+onError: error => {
+ showToast.error(getSignatureErrorMessage(error));
+ // getSignatureErrorMessage returns either:
+ // - WALLET_ERROR_COPY.SIGNATURE_REJECTED (user clicked "Cancel")
+ // - WALLET_ERROR_COPY.SIGNATURE_FAILED (other wallet-side failure)
+};
+```
+
+`getSignatureErrorMessage` is implemented in
+[`src/utils/errorHandling.utils.ts`](./../src/utils/errorHandling.utils.ts)
+and detects the EIP-1193 code `4001`, ethers' `ACTION_REJECTED`, and the
+common message fragments "user rejected" / "declined" / "cancelled".
+
+### Pattern: Off-chain mutation that should NOT use a drawer
+
+Copy-to-clipboard, share-to-Twitter, follow a creator — all of these are
+writes that have no chain side effects. Just toast:
+
+```ts
+// Excerpt from CreatorProfileHeader
+const handleShare = async () => {
+ try {
+ await navigator.clipboard.writeText(profileUrl);
+ showToast.success('Profile link copied to clipboard!');
+ } catch {
+ showToast.error('Could not copy the profile link. Please try again.');
+ }
+};
+```
+
+---
+
+## Mode 2 — Inline Error State for Blocking Query Failures
+
+**Use when:**
+
+- The query is the primary content of the page (e.g. creator profile header).
+- Without the data, the screen is empty; there is nothing else for the user
+ to do here.
+- You want the user to retry without leaving the page — wire `refetch` from
+ React Query.
+
+**Don't use when:**
+
+- The query is enriching a page that can render something else (use Mode 3).
+- The failure came from a mutation (use Mode 1).
+
+### Pattern: Canonical shared component
+
+`CreatorProfileErrorState` is the canonical inline error component. It
+renders a marketplace-styled card with an icon, a message, and an optional
+retry button.
+
+```tsx
+// In a creator profile section
+import { useCreatorProfile } from '@/hooks/useCreatorProfile';
+import CreatorProfileErrorState from '@/components/common/CreatorProfileErrorState';
+import { ApiError } from '@/services/api.service';
+
+function CreatorHeader({ creatorId }: { creatorId: string }) {
+ const { data, isLoading, isError, error, refetch } =
+ useCreatorProfile(creatorId);
+
+ if (isLoading) return void refetch()}
+ isRetrying={
+ false /* wire from your query's isFetching if you want */
+ }
+ title="Unable to load this creator profile"
+ />
+ );
+ }
+
+ return
+ {apiError.status >= 500
+ ? 'Unable to load holdings. Please try again later.'
+ : apiError.message}
+
+
+
+ );
+}
+```
+
+### Inline vs. throw-to-boundary — the rule
+
+> If the failure should leave the rest of the page interactive → render an
+> **inline** state. If it means the route as a whole cannot be useful → throw
+> the error and let the page-level boundary catch it.
+
+Concretely:
+
+- A creator list failing inside the marketplace page? **Inline.** The hero,
+ filters, and holdings are still useful.
+- The creator profile header failing on `/creator/:id`? **Throw** →
+ `CreatorPageErrorBoundary` renders a "Creator not found" or
+ "could not load" page-level state and a back-link.
+
+---
+
+## Mode 3 — Section Error Boundary (Render Falls Here)
+
+**Use when:**
+
+- A sub-component (tab body, sidebar, list section) can throw during render
+ — e.g. it consumes data that is undefined when the parent didn't gate it.
+- A failure in **this section** should not crash the whole page.
+- The user should be able to retry the section without a full reload.
+
+**Don't use when:**
+
+- The error is a query failure (React Query surfaces it via `isError` —
+ branch in the component, don't throw).
+- The error is from an on-chain mutation (use Mode 5).
+
+### Pattern: Wrap any sub-tree that might throw
+
+```tsx
+import SectionErrorBoundary from '@/components/common/SectionErrorBoundary';
+
+// In LandingPage
+
+ ;
+```
+
+The retry button on the fallback resets the boundary's internal error
+state; it does **not** re-fire the underlying `useQuery`. If you need a
+network retry, combine the boundary with a query that has `enabled` tied
+to a "retry counter" `useState` and bump it inside the retry handler.
+
+### Pair with `throwOnError`
+
+If you want React Query to throw a render-time exception (so the boundary
+catches it) instead of branching on `isError` inside the component, opt in
+on the query:
+
+```ts
+useQuery({
+ queryKey: queryKeys.creators.detail(id),
+ queryFn: () => courseService.getById(id),
+ throwOnError: error => {
+ const api = error as ApiError;
+ // 4xx: render inline; 5xx: bubble to boundary
+ return api.status >= 500;
+ },
+});
+```
+
+See [Error Handling in Hooks → SectionErrorBoundary](./error-handling-in-hooks.md#use-sectionerrorboundary-when)
+for the full reasoning.
+
+---
+
+## Mode 4 — Page-Level Error Boundaries
+
+There are two nested page boundaries; pick the **most specific** one that
+fits the route.
+
+### `CreatorPageErrorBoundary` — creator routes
+
+Scoped to `/creator/:id` and any other creator detail route. When a creator
+page throws, this catches it and renders a fallback with a "back to
+creators" link. It special-cases `ApiError` with `status === 404` to render
+a "Creator not found" message instead of a generic failure.
+
+```tsx
+// src/pages/CreatorDetailPage.tsx
+import CreatorPageErrorBoundary from '@/components/common/CreatorPageErrorBoundary';
+
+export default function CreatorDetailPage() {
+ const { id } = useParams<{ id: string }>();
+ const { data, isLoading, error } = useCreatorDetail(id ?? '');
+
+ if (!data && !isLoading) {
+ throw new ApiError('Creator not found', 404);
+ }
+ if (error) {
+ throw error; // → CreatorPageErrorBoundary
+ }
+
+ return {routes} ;
+```
+
+### `AppErrorBoundary` — last line of defense
+
+Mounted once in [`src/App.tsx`](./../src/App.tsx) around the router. When
+something throws that isn't caught by a more specific boundary, this is
+the last chance before React would otherwise unmount the entire tree. The
+fallback offers a **full page reload** rather than resetting local state —
+the rationale is documented in the component's source comment.
+
+Reach: anything that escapes a `SectionErrorBoundary` or
+`CreatorPageErrorBoundary` will land here.
+
+---
+
+## Mode 5 — Transaction Failure Surfaces
+
+Buy / sell / claim trades have **two** surfaces: an inline
+`TransactionRetryNotice` so the user sees a persistent recovery prompt,
+and a modal `TransactionFailureDrawer` for full diagnostic detail.
+
+### When to use both together
+
+A failed trade should:
+
+1. Show a `TransactionRetryNotice` in place of the trade action area —
+ it stays visible until the user retries or dismisses.
+2. Open a `TransactionFailureDrawer` so the user can copy the error code
+ or transaction hash for support.
+
+```tsx
+// src/components/common/CreatorCard.tsx (excerpt)
+import TransactionRetryNotice from '@/components/common/TransactionRetryNotice';
+import TransactionFailureDrawer from '@/components/common/TransactionFailureDrawer';
+import type { TransactionFailureDetails } from '@/components/common/TransactionFailureDrawer';
+
+const [failure, setFailure] = useState(null);
+
+const handleTrade = async (amount: number) => {
+ try {

+`TransactionFailureDetails`:
+
+| Field | Type | Purpose |
+| ------------------ | -------------------------- | ---------------------------------------------- |
+| `errorMessage` | `string` (required) | User-facing message displayed in the drawer |
+| `txHash` | `string?` | On-chain hash for support; copy-to-clipboard |
+| `errorCode` | `string?` | Machine code (e.g. `INSUFFICIENT_BALANCE`) |
+| `timestamp` | `number?` | Unix ms; rendered via `formatTimestampTooltip` |
+| `developerDetails` | `Record?` | Hidden behind a `` toggle for devs |
+
+See [`src/components/common/TransactionFailureDrawer.tsx`](./../src/components/common/TransactionFailureDrawer.tsx)
+for the component contract.
+
+### When to NOT use the drawer
+
+If the action is not on-chain (share, copy, follow) — toast only. The
+drawer exists to expose blockchain-detail information; if there is no
+chain context, it adds noise.
+
+---
+
+## Mode 6 — Network Mismatch Banner
+
+`NetworkMismatchBanner` is **always-on**: it reads from
+`useNetworkMismatch()` and returns `null` when the wallet is on the
+correct network. Mount it once in any layout where users can initiate
+trades; it renders nothing in the happy path.
+
+```tsx
+// Wherever the user can trade
+
+
+```
+
+This is **not** an error per se — it's a precondition warning. Do **not**
+also toast "wrong network" on top of this banner; the banner is the
+canonical surface.
+
+---
+
+## Branching on `ApiError.status` — Consolidated Cheat Sheet
+
+The same numeric scale drives every mode. Source:
+[`src/services/api.service.ts`](./../src/services/api.service.ts) →
+[`BaseApiService.handleError`](./../src/services/api.service.ts).
+
+| `apiError.status` | Meaning | Toast copy | Inline copy | Boundary fallback |
+| ----------------- | ------------------------ | ---------------------------------------------------------- | ------------------------------------------- | ----------------------------------------------- |
+| `0` | No network response | "Network error. Check your connection and try again." | "Check your connection and try again." | `AppErrorBoundary` |
+| `400` | Malformed request | `apiError.message` (safe) | `apiError.message` | `AppErrorBoundary` |
+| `401` | Session expired | (interceptor handles — auto-refresh, redirect to `/login`) | n/a | n/a |
+| `403` | Insufficient permissions | `apiError.message` | "You don't have access to this." | `AppErrorBoundary` |
+| `404` | Resource not found | `apiError.message` | "Not found." | `CreatorPageErrorBoundary` (404 special-cases) |
+| `422` | Validation failure | `apiError.response.errors[0].message` (first field error) | Map every `response.errors[i]` to its input | `AppErrorBoundary` |
+| `429` | Rate limited | "Too many requests. Please wait a moment and retry." | "Rate limited. Try again shortly." | `AppErrorBoundary` |
+| `>= 500` | Server error | "The server ran into a problem. Please try again shortly." | "Unable to load this. Try again later." | Section-level (skeleton→empty→relies on inline) |
+
+---
+
+## Adding a New Error Type to the Classification System
+
+The codebase has **two** classification helpers that capture domain
+specifics. Pick the one that matches your domain; do not invent a new
+helper unless neither fits.
+
+### 1. Wallet & signature errors → extend `WALLET_ERROR_COPY`
+
+File: [`src/utils/errorHandling.utils.ts`](./../src/utils/errorHandling.utils.ts).
+
+Centralized map of wallet-and-signature messages, plus detection helpers:
+
+```ts
+export const WALLET_ERROR_COPY = {
+ SIGNATURE_REJECTED:
+ "Signature request was declined. Please try again when you're ready to confirm.",
+ SIGNATURE_FAILED:
+ 'The signature request failed. Please ensure your wallet is unlocked and try again.',
+ GENERIC_TRANSACTION_FAILED:
+ 'Transaction failed. Please check your balance or connection and try again.',
+};
+
+export function isUserRejection(error: unknown): boolean {
+ /* … */
+}
+export function getSignatureErrorMessage(error: unknown): string {
+ /* … */
+}
+```
+
+**To add a new wallet error type:**
+
+1. Append a new key to `WALLET_ERROR_COPY` with a sentence that states the
+ cause and the next step.
+2. If the detector matters, extend `isUserRejection`-style recognition in
+ a new exported predicate (`isRateLimited(error)`, `isChainSwitchRequired(error)`).
+3. Wire the predicate + key into the calling hook's `onError` — usually
+ by extending `getSignatureErrorMessage` or introducing a sibling
+ `getWalletErrorMessage` if the surface is broader than signatures.
+4. Add a Vitest unit test under
+ `src/utils/__tests__/errorHandling.utils.test.ts` that pins the new
+ copy and predicate behavior.
+
+### 2. Pre-action disabled reasons → extend the typed helper
+
+File: [`src/utils/claimActionDisabledReason.ts`](./../src/utils/claimActionDisabledReason.ts).
+
+Pattern: a **closed union** of reason keys + a **single `Record`** that
+maps each key to a standardized copy. This pattern is reused for other
+disabled-reason surfaces (see `BuyActionHelperText` and
+`ClaimActionHelperText` documentation).
+
+```ts
+export type ClaimActionDisabledReasonKey =
+ | 'wallet_not_connected'
+ | 'no_claimable_rewards'
+ | 'claim_in_progress'
+ | 'network_mismatch'
+ | 'insufficient_gas'
+ | 'unknown';
+
+const CLAIM_ACTION_DISABLED_REASON_TEXT: Record<
+ ClaimActionDisabledReasonKey,
+ string
+> = {
+ // Every entry follows the same shape:
+ // "{Action} is unavailable because {cause}. {Next step}."
+ wallet_not_connected:
+ 'Claim is unavailable because your wallet is not connected. Connect your wallet to continue.',
+ // …
+};
+
+export const getClaimActionDisabledReasonText = (
+ reason: ClaimActionDisabledReasonKey
+): string => CLAIM_ACTION_DISABLED_REASON_TEXT[reason];
+```
+
+**To add a new disabled reason:**
+
+1. Append the new key to the union — **don't** fall back to `unknown`
+ silently; force every caller to make a decision.
+2. Add a matching entry to `CLAIM_ACTION_DISABLED_REASON_TEXT` using the
+ "{Action} is unavailable because {cause}. {Next step}." template so
+ tones stay consistent.
+3. Compute the new key at the call site (the component that evaluates
+ pre-conditions) and pass it to `getClaimActionDisabledReasonText`.
+4. Extend
+ `src/utils/__tests__/claimActionDisabledReason.test.ts` to cover the
+ new key.
+
+### 3. When neither helper fits
+
+If your error surface is genuinely new (e.g. diverging-chain detection,
+on-chain simulation errors), create a new sibling helper in
+`src/utils/ErrorHandling.utils.ts` following the same shape:
+
+1. **Closed key union** — TypeScript exhaustiveness forces callers to
+ pick a copy.
+2. **One Record/Map** that owns _all_ English copy — no copy scattered
+ across components.
+3. **Pure functions** — no React, no hooks, no side effects. Easy to
+ unit-test.
+4. **Side-by-side tests** — colocated unit test in
+ `src/utils/__tests__/`.
+
+Do not duplicate copy inline in components; always go through a typed
+helper so future copy edits stay coherent.
+
+---
+
+## Shared Error State Components — Reference
+
+| Component | Mode | Purpose | Key props |
+| -------------------------------------------------- | ---- | --------------------------------------------------- | ------------------------------------------------------------------------- |
+| `showToast` (`@/utils/toast.util`) | 1 | Mutation feedback (success, error, loading, tx) | `showToast.{success,error,loading,transactionSuccess}(message, options?)` |
+| `CreatorProfileErrorState` (`@/components/common`) | 2 | Canonical inline error card for creator profile | `error?, onRetry?, isRetrying?, title?, message?` |
+| `SectionErrorBoundary` (`@/components/common`) | 3 | Catches sub-tree render throws with retry | `sectionName?, minHeight?, className?` |
+| `CreatorPageErrorBoundary` (`@/components/common`) | 4 | Catches creator-route render throws | none (wraps ``) |
+| `AppErrorBoundary` (`@/components/common`) | 4 | App-wide last-line-of-defense; full reload on retry | none (wraps ``) |
+| `TransactionRetryNotice` (`@/components/common`) | 5 | Persistent inline retry banner for failed trades | `title?, message, onRetry, retryLabel?, disabled?, className?` |
+| `TransactionFailureDrawer` (`@/components/common`) | 5 | Modal with error code, hash, and developer details | `open, onOpenChange?, failureDetails, onRetry?, onDismiss?` |
+| `NetworkMismatchBanner` (`@/components/common`) | 6 | Persistent "wrong network" warning | `className?` |
+
+For accessible state components (skeletons, empty states), see
+[Adding a Page and Data Fetching](./adding-page-and-data-fetching.md)
+and [Shared Components](./shared-components.md).
+
+---
+
+## Worked Examples
+
+### Example A — Marketplace search list (read failure → Mode 2)
+
+The creator list inside the marketplace is critical content, so a query
+failure renders an inline state with retry. The rest of the page
+(hero, holdings, footer) stays interactive.
+
+```tsx
+// src/pages/LandingPage.tsx (excerpt)
+const { data: creators, isError, error, refetch } = useCreatorList();
+
+if (isError) {
+ const apiError = error as ApiError;
+ return (
+
+ Couldn't load the creator list
+
+ {apiError.status >= 500
+ ? 'Something went wrong on our end. Please try again.'
+ : apiError.message}
+
+
+
+ );
+}
+
+return
+
+ );
+}
+```
+
+### Example C — Buy flow (mutation failure → Mode 1 + Mode 5)
+
+A trade mutation has both the prompt (toast), the persistent retry
+banner, and the detail drawer:
+
+```tsx
+// src/components/common/CreatorCard.tsx (excerpt)
+const buy = useBuyCreatorKey();
+
+const handleBuy = async (amount: number) => {
+ try {
+ await buy.mutateAsync({ creatorId, amount });
+ } catch (err) {
+ const apiError = err as ApiError;
+
+ // Mode 1: quick prompt
+ showToast.error(
+ apiError.status === 0
+ ? 'Network error. Check your connection.'
+ : apiError.message
+ );
+
+ // Mode 5: persistent banner + drawer for support detail
+ setFailure({
+ errorMessage: apiError.message,
+ errorCode: apiError.response?.code,
+ timestamp: Date.now(),
+ });
+ }
+};
+```
+
+---
+
+## Quick Reference
+
+| Question | Answer |
+| ----------------------------------------------------- | ----------------------------------------------------- |
+| Failure from a button click? | Toast (Mode 1), add drawer for on-chain trades |
+| Failure from `useQuery` that **is** the page? | Throw → Page boundary (Mode 4) |
+| Failure from `useQuery` that **enriches** the page? | Inline state with `refetch` (Mode 2) |
+| Component throws during render (not a query error)? | Wrap in `SectionErrorBoundary` (Mode 3) |
+| Wallet is connected but wrong chain? | `NetworkMismatchBanner` (Mode 6) |
+| User clicked "Cancel" on the wallet signature prompt? | `getSignatureErrorMessage` (Mode 1, specialised copy) |
+| New kind of wallet error? | Extend `WALLET_ERROR_COPY` |
+| New pre-action disabled reason? | Extend `ClaimActionDisabledReasonKey` + lookup |

+# Error Handling in React Query Hooks
+
+This guide documents the standard pattern for handling API errors in React Query hooks across this codebase. Follow it when writing new `useQuery` or `useMutation` hooks so error behavior is consistent and predictable for users.
+
+---
+
+## How Errors Flow In
+
+All HTTP requests go through the service layer (`src/services/`), which extends `BaseApiService`. The `handleError` method on that base class normalises every failure into an `ApiError` before it reaches the hook:
+
+| Raw failure | What you receive |
+| ------------------------------------- | ------------------------------------------------------ |
+| HTTP response with an error status | `ApiError(message, httpStatus, responseBody)` |
+| Request sent but no response received | `ApiError('Network error - check your connection', 0)` |
+| Unexpected non-HTTP exception | `ApiError(error.message, 500)` |
+
+One important exception: **401 + `TOKEN_EXPIRED`** is handled transparently by the Axios interceptor in `BaseApiService`. The interceptor silently retries the original request after refreshing the access token. If the refresh also fails the user is redirected to `/login`; the hook never sees this error.
+
+---
+
+## The `ApiError` Shape
+
+```ts
+// src/services/api.service.ts
+class ApiError extends Error {
+ status: number; // HTTP status code; 0 means no network response
+ response?: {
+ success: false;
+ message: string;
+ code?: string; // machine-readable code from the API, e.g. "INSUFFICIENT_BALANCE"
+ errors?: Array<{
+ field?: string; // present on 422 validation failures
+ message: string;
+ }>;
+ };
+}
+```
+
+Always cast the error to `ApiError` before inspecting it:
+
+```ts
+import { ApiError } from '@/services/api.service';
+
+onError: error => {
+ const apiError = error as ApiError;
+ console.log(apiError.status); // 0, 400, 403, 422, 500 …
+ console.log(apiError.message); // human-readable message from the API
+ console.log(apiError.response?.errors); // field-level details on 422
+};
+```
+
+---
+
+## Distinguishing Error Types
+
+### Network errors (`status === 0`)
+
+No response was received — the user is offline, the server is unreachable, or a timeout occurred. The user cannot fix the request payload; they need to retry later.
+
+```ts
+if (apiError.status === 0) {
+ showToast.error('Network error. Check your connection and try again.');
+ return;
+}
+```
+
+### 4xx — Client errors
+
+The request was received but rejected because of something the client sent. The message from the API is usually safe to show to the user.
+
+| Status | Cause | Typical UI response |
+| ------ | ------------------------ | ---------------------------------------------------- |
+| 400 | Malformed request | Toast with `apiError.message` |
+| 401 | Session expired | Auto-handled by the interceptor |
+| 403 | Insufficient permissions | Inline error or redirect |
+| 404 | Resource not found | Inline error state |
+| 422 | Validation failure | Inline field errors from `apiError.response?.errors` |
+| 429 | Rate limited | Toast with retry suggestion |
+
+### 5xx — Server errors
+
+The API itself failed. The user cannot fix the payload; they can only retry after the server recovers. Avoid showing raw server messages — use a generic fallback instead.
+
+```ts
+if (apiError.status >= 500) {
+ showToast.error('The server ran into a problem. Please try again shortly.');
+ return;
+}
+```
+
+---
+
+## Deciding: Toast vs. Inline Error vs. Error Boundary
+
+### Use a toast when
+
+- The failure came from a **user-initiated action** (mutation): buying a key, submitting a form, enrolling in a course.
+- The error **does not block the current view** — the page can still render usefully.
+- The fix is to retry or change input: one line of feedback is enough.
+
+```ts
+onError: error => {
+ const apiError = error as ApiError;
+ showToast.error(
+ apiError.status >= 500
+ ? 'Something went wrong. Try again.'
+ : apiError.message
+ );
+};
+```
+
+### Use an inline error state when
+
+- The error **blocks the primary purpose of the screen** — for example, the creator list failed to load so the page is empty.
+- The error contains **field-level detail** (422) that needs to map to specific form inputs.
+- The user needs to take **corrective action** (fix a field, switch networks) before retrying makes sense.
+
+```tsx
+const { data, isError, error } = useCreatorKeys(creatorId);
+
+if (isError) {
+ const apiError = error as ApiError;
+ return (
+
+ {apiError.status >= 500
+ ? 'Unable to load data. Please try again later.'
+ : apiError.message}
+
+ );
+}
+```
+
+### Use `SectionErrorBoundary` when
+
+- A **component throws during render**, not from an API call.
+- You want to **isolate a section** so one broken widget does not crash the whole page.
+- React Query's `throwOnError` option is enabled on a query.
+
+```tsx
+import SectionErrorBoundary from '@/components/common/SectionErrorBoundary';
+
+
+ ;
+```
+
+`SectionErrorBoundary` renders a retry button that resets its own error state. Use it as a safety net around sections that fetch and render data together.
+
+---
+
+## `useQuery` Pattern
+
+React Query v5 removed the `onError` callback from `useQuery`. Errors surface through `isError` and `error` in the component. Keep the hook thin and handle the error at the call site:
+
+```ts
+// src/hooks/useCreatorProfile.ts
+import { useQuery } from '@tanstack/react-query';
+import { creatorService } from '@/services/creator.service';
+
+export function useCreatorProfile(creatorId: string) {
+ return useQuery({
+ queryKey: ['creator-profile', creatorId],
+ queryFn: () => creatorService.getProfile(creatorId),
+ staleTime: 30_000,
+ });
+}
+```
+
+```tsx
+// In the component
+import { ApiError } from '@/services/api.service';
+import { useCreatorProfile } from '@/hooks/useCreatorProfile';
+
+function CreatorProfileSection({ creatorId }: { creatorId: string }) {
+ const { data, isLoading, isError, error } = useCreatorProfile(creatorId);
+
+ if (isLoading) return
+ {apiError.status >= 500
+ ? 'Unable to load keys right now. Please try again later.'
+ : apiError.message}
+
+
+ );
+ }
+
+ return (
+ // SectionErrorBoundary catches any render-time throws inside KeysList
+
+ buyKey({ creatorId, amount })}
+ isBuying={isPending}
+ />
+
+ );
+}
+```
+
+---
+
+## Quick Reference
+
+| Condition | Check | UI response |
+| ------------------- | ------------------------------- | ------------------------------------------------------------ |
+| No network response | `apiError.status === 0` | Toast: "Network error. Check your connection." |
+| Server error | `apiError.status >= 500` | Toast: generic "something went wrong" message |
+| Validation failure | `apiError.status === 422` | Toast or inline: first item from `apiError.response?.errors` |
+| Other 4xx | `apiError.status >= 400` | Toast or inline: `apiError.message` (safe from the API) |
+| Read query fails | `isError === true` in component | Inline error state replacing the content area |
+| Render throws | Component boundary | Wrap with `` |

+# Editing Marketing Page Copy
+
+This guide is for non-technical contributors who want to suggest changes to the
+marketing page copy. You can edit the text directly on GitHub and open a pull
+request — no local development environment is required.
+
+## Where the copy lives
+
+All marketing page copy is in a single file:
+
+**`src/pages/MarketingPage.tsx`**
+
+The page is a single React component. Each visible section is a block of JSX
+with inline text. Use the table below to find the section you want to change.
+
+| Visible section on the page | Location in `MarketingPage.tsx` | What to look for |
+| ------------------------------- | ----------------------------------------- | ------------------------------------------------------------------------------ |
+| Page title ("Access Layer") | Hero / Title | `` with the `Access Layer` heading |
+| Intro paragraph under the title | Intro | First `
` after the title |
+| **The idea** | `{/* The idea */}` section | Eyebrow text `The idea` and the two body paragraphs below it |
+| **How it works** | `{/* How it works */}` section | Eyebrow text `How it works` and the two body paragraphs below it |
+| **What makes it different** | `{/* What makes it different */}` section | Eyebrow text `What makes it different` and the body paragraph below it |
+| **Built on Stellar** | `{/* Built on Stellar */}` section | Eyebrow text `Built on Stellar` and the two body paragraphs below it |
+| **Join the community** | `{/* Community */}` section | Eyebrow text `Join the community`, the subtitle, and the GitHub/Telegram links |
+| Footer | `{/* Footer */}` section | Logo label and the "Built on Stellar" tagline |
+
+Section eyebrows use this pattern — a short uppercase label in blue:
+

+
+ The idea

+```

+/**
+ * Integration test for holdings entry count after buy/sell sequence (#TBD).
+ *
+ * The holdings list should add an entry when a buy confirms for a new creator
+ * and remove it when all keys for that creator are sold. Additional keys for
+ * an existing creator must not produce a duplicate entry.
+ *
+ * Held positions are derived from the API response:
+ * index 0 → featuredHoldings (mutable via TradeDialog, starts at 3)
+ * index 1+ → DEMO_HELD_KEY_QUANTITIES (fixed per session)
+ *
+ * Flow (2 creators returned by the API):
+ * 1. Initial: featuredHoldings=3 (Creator A) + 2 keys (Creator B) → 2 entries
+ * 2. Sell all 3 keys of Creator A → 1 entry (only Creator B)
+ * 3. Buy 1 key of Creator A → 2 entries (A re-added, B still present)
+ * 4. Buy 2 more keys of Creator A → still 2 entries (no duplicate)
+ * 5. Sell all 3 keys of Creator A → 1 entry (only Creator B again)
+ *
+ * Acceptance criteria covered:
+ * - Entry added when a buy confirms for a new creator (step 3)
+ * - Entry not duplicated when additional keys are bought (step 4)
+ * - Entry removed when all keys for a creator are sold (steps 2, 5)
+ * - Entry count correct after each state change (all steps)

+one and the user has no escape hatch.
+
+```tsx
+const { data, isError, error, refetch } = useHoldings(address);
+
+if (isError) {
+ const apiError = error as ApiError;
+ return (
+
+ ;
+```
+
+The retry button on the fallback resets the boundary's internal error
+state; it does **not** re-fire the underlying `useQuery`. If you need a
+network retry, combine the boundary with a query that has `enabled` tied
+to a "retry counter" `useState` and bump it inside the retry handler.
+
+### Pair with `throwOnError`
+
+If you want React Query to throw a render-time exception (so the boundary
+catches it) instead of branching on `isError` inside the component, opt in
+on the query:
+
+```ts
+useQuery({
+ queryKey: queryKeys.creators.detail(id),
+ queryFn: () => courseService.getById(id),
+ throwOnError: error => {
+ const api = error as ApiError;
+ // 4xx: render inline; 5xx: bubble to boundary
+ return api.status >= 500;
+ },
+});
+```
+
+See [Error Handling in Hooks → SectionErrorBoundary](./error-handling-in-hooks.md#use-sectionerrorboundary-when)
+for the full reasoning.
+
+---
+
+## Mode 4 — Page-Level Error Boundaries
+
+There are two nested page boundaries; pick the **most specific** one that
+fits the route.
+
+### `CreatorPageErrorBoundary` — creator routes
+
+Scoped to `/creator/:id` and any other creator detail route. When a creator
+page throws, this catches it and renders a fallback with a "back to
+creators" link. It special-cases `ApiError` with `status === 404` to render
+a "Creator not found" message instead of a generic failure.
+
+```tsx
+// src/pages/CreatorDetailPage.tsx
+import CreatorPageErrorBoundary from '@/components/common/CreatorPageErrorBoundary';
+
+export default function CreatorDetailPage() {
+ const { id } = useParams<{ id: string }>();
+ const { data, isLoading, error } = useCreatorDetail(id ?? '');
+
+ if (!data && !isLoading) {
+ throw new ApiError('Creator not found', 404);
+ }
+ if (error) {
+ throw error; // → CreatorPageErrorBoundary
+ }
+
+ return {routes} ;
+```
+
+### `AppErrorBoundary` — last line of defense
+
+Mounted once in [`src/App.tsx`](./../src/App.tsx) around the router. When
+something throws that isn't caught by a more specific boundary, this is
+the last chance before React would otherwise unmount the entire tree. The
+fallback offers a **full page reload** rather than resetting local state —
+the rationale is documented in the component's source comment.
+
+Reach: anything that escapes a `SectionErrorBoundary` or
+`CreatorPageErrorBoundary` will land here.
+
+---
+
+## Mode 5 — Transaction Failure Surfaces
+
+Buy / sell / claim trades have **two** surfaces: an inline
+`TransactionRetryNotice` so the user sees a persistent recovery prompt,
+and a modal `TransactionFailureDrawer` for full diagnostic detail.
+
+### When to use both together
+
+A failed trade should:
+
+1. Show a `TransactionRetryNotice` in place of the trade action area —
+ it stays visible until the user retries or dismisses.
+2. Open a `TransactionFailureDrawer` so the user can copy the error code
+ or transaction hash for support.
+
+```tsx
+// src/components/common/CreatorCard.tsx (excerpt)
+import TransactionRetryNotice from '@/components/common/TransactionRetryNotice';
+import TransactionFailureDrawer from '@/components/common/TransactionFailureDrawer';
+import type { TransactionFailureDetails } from '@/components/common/TransactionFailureDrawer';
+
+const [failure, setFailure] = useState(null);
+
+const handleTrade = async (amount: number) => {
+ try {
+ await buyKey({ creatorId, amount });
+ } catch (err) {
+ const apiError = err as ApiError;
+ setFailure({
+ errorMessage: apiError.message,
+ errorCode: apiError.response?.code,
+ txHash: undefined, // chain-specific; pass when available
+ timestamp: Date.now(),
+ developerDetails: apiError.response,
+ });
+ }
+};
+
+return (
+ <>
+ {failure && (
+ <>
+ {
+ setFailure(null);
+ handleTrade(lastAmount);
+ }}
+ />
+ {
+ setFailure(null);
+ handleTrade(lastAmount);
+ }}
+ onDismiss={() => setFailure(null)}
+ />
+
+ )}
+
+);
+```
+
+`TransactionFailureDetails`:
+
+| Field | Type | Purpose |
+| ------------------ | -------------------------- | ---------------------------------------------- |
+| `errorMessage` | `string` (required) | User-facing message displayed in the drawer |
+| `txHash` | `string?` | On-chain hash for support; copy-to-clipboard |
+| `errorCode` | `string?` | Machine code (e.g. `INSUFFICIENT_BALANCE`) |
+| `timestamp` | `number?` | Unix ms; rendered via `formatTimestampTooltip` |
+| `developerDetails` | `Record?` | Hidden behind a `
)}
- {/* Sparkline placeholder */}
-
+
+ );
+}
+```
+
+### Inline vs. throw-to-boundary — the rule
+
+> If the failure should leave the rest of the page interactive → render an
+> **inline** state. If it means the route as a whole cannot be useful → throw
+> the error and let the page-level boundary catch it.
+
+Concretely:
+
+- A creator list failing inside the marketplace page? **Inline.** The hero,
+ filters, and holdings are still useful.
+- The creator profile header failing on `/creator/:id`? **Throw** →
+ `CreatorPageErrorBoundary` renders a "Creator not found" or
+ "could not load" page-level state and a back-link.
+
+---
+
+## Mode 3 — Section Error Boundary (Render Falls Here)
+
+**Use when:**
+
+- A sub-component (tab body, sidebar, list section) can throw during render
+ — e.g. it consumes data that is undefined when the parent didn't gate it.
+- A failure in **this section** should not crash the whole page.
+- The user should be able to retry the section without a full reload.
+
+**Don't use when:**
+
+- The error is a query failure (React Query surfaces it via `isError` —
+ branch in the component, don't throw).
+- The error is from an on-chain mutation (use Mode 5).
+
+### Pattern: Wrap any sub-tree that might throw
+
+```tsx
+import SectionErrorBoundary from '@/components/common/SectionErrorBoundary';
+
+// In LandingPage
++ {apiError.status >= 500 + ? 'Unable to load holdings. Please try again later.' + : apiError.message} +
+ +` toggle for devs |
+
+See [`src/components/common/TransactionFailureDrawer.tsx`](./../src/components/common/TransactionFailureDrawer.tsx)
+for the component contract.
+
+### When to NOT use the drawer
+
+If the action is not on-chain (share, copy, follow) — toast only. The
+drawer exists to expose blockchain-detail information; if there is no
+chain context, it adds noise.
+
+---
+
+## Mode 6 — Network Mismatch Banner
+
+`NetworkMismatchBanner` is **always-on**: it reads from
+`useNetworkMismatch()` and returns `null` when the wallet is on the
+correct network. Mount it once in any layout where users can initiate
+trades; it renders nothing in the happy path.
+
+```tsx
+// Wherever the user can trade
+
+
+```
+
+This is **not** an error per se — it's a precondition warning. Do **not**
+also toast "wrong network" on top of this banner; the banner is the
+canonical surface.
+
+---
+
+## Branching on `ApiError.status` — Consolidated Cheat Sheet
+
+The same numeric scale drives every mode. Source:
+[`src/services/api.service.ts`](./../src/services/api.service.ts) →
+[`BaseApiService.handleError`](./../src/services/api.service.ts).
+
+| `apiError.status` | Meaning | Toast copy | Inline copy | Boundary fallback |
+| ----------------- | ------------------------ | ---------------------------------------------------------- | ------------------------------------------- | ----------------------------------------------- |
+| `0` | No network response | "Network error. Check your connection and try again." | "Check your connection and try again." | `AppErrorBoundary` |
+| `400` | Malformed request | `apiError.message` (safe) | `apiError.message` | `AppErrorBoundary` |
+| `401` | Session expired | (interceptor handles — auto-refresh, redirect to `/login`) | n/a | n/a |
+| `403` | Insufficient permissions | `apiError.message` | "You don't have access to this." | `AppErrorBoundary` |
+| `404` | Resource not found | `apiError.message` | "Not found." | `CreatorPageErrorBoundary` (404 special-cases) |
+| `422` | Validation failure | `apiError.response.errors[0].message` (first field error) | Map every `response.errors[i]` to its input | `AppErrorBoundary` |
+| `429` | Rate limited | "Too many requests. Please wait a moment and retry." | "Rate limited. Try again shortly." | `AppErrorBoundary` |
+| `>= 500` | Server error | "The server ran into a problem. Please try again shortly." | "Unable to load this. Try again later." | Section-level (skeleton→empty→relies on inline) |
+
+---
+
+## Adding a New Error Type to the Classification System
+
+The codebase has **two** classification helpers that capture domain
+specifics. Pick the one that matches your domain; do not invent a new
+helper unless neither fits.
+
+### 1. Wallet & signature errors → extend `WALLET_ERROR_COPY`
+
+File: [`src/utils/errorHandling.utils.ts`](./../src/utils/errorHandling.utils.ts).
+
+Centralized map of wallet-and-signature messages, plus detection helpers:
+
+```ts
+export const WALLET_ERROR_COPY = {
+ SIGNATURE_REJECTED:
+ "Signature request was declined. Please try again when you're ready to confirm.",
+ SIGNATURE_FAILED:
+ 'The signature request failed. Please ensure your wallet is unlocked and try again.',
+ GENERIC_TRANSACTION_FAILED:
+ 'Transaction failed. Please check your balance or connection and try again.',
+};
+
+export function isUserRejection(error: unknown): boolean {
+ /* … */
+}
+export function getSignatureErrorMessage(error: unknown): string {
+ /* … */
+}
+```
+
+**To add a new wallet error type:**
+
+1. Append a new key to `WALLET_ERROR_COPY` with a sentence that states the
+ cause and the next step.
+2. If the detector matters, extend `isUserRejection`-style recognition in
+ a new exported predicate (`isRateLimited(error)`, `isChainSwitchRequired(error)`).
+3. Wire the predicate + key into the calling hook's `onError` — usually
+ by extending `getSignatureErrorMessage` or introducing a sibling
+ `getWalletErrorMessage` if the surface is broader than signatures.
+4. Add a Vitest unit test under
+ `src/utils/__tests__/errorHandling.utils.test.ts` that pins the new
+ copy and predicate behavior.
+
+### 2. Pre-action disabled reasons → extend the typed helper
+
+File: [`src/utils/claimActionDisabledReason.ts`](./../src/utils/claimActionDisabledReason.ts).
+
+Pattern: a **closed union** of reason keys + a **single `Record`** that
+maps each key to a standardized copy. This pattern is reused for other
+disabled-reason surfaces (see `BuyActionHelperText` and
+`ClaimActionHelperText` documentation).
+
+```ts
+export type ClaimActionDisabledReasonKey =
+ | 'wallet_not_connected'
+ | 'no_claimable_rewards'
+ | 'claim_in_progress'
+ | 'network_mismatch'
+ | 'insufficient_gas'
+ | 'unknown';
+
+const CLAIM_ACTION_DISABLED_REASON_TEXT: Record<
+ ClaimActionDisabledReasonKey,
+ string
+> = {
+ // Every entry follows the same shape:
+ // "{Action} is unavailable because {cause}. {Next step}."
+ wallet_not_connected:
+ 'Claim is unavailable because your wallet is not connected. Connect your wallet to continue.',
+ // …
+};
+
+export const getClaimActionDisabledReasonText = (
+ reason: ClaimActionDisabledReasonKey
+): string => CLAIM_ACTION_DISABLED_REASON_TEXT[reason];
+```
+
+**To add a new disabled reason:**
+
+1. Append the new key to the union — **don't** fall back to `unknown`
+ silently; force every caller to make a decision.
+2. Add a matching entry to `CLAIM_ACTION_DISABLED_REASON_TEXT` using the
+ "{Action} is unavailable because {cause}. {Next step}." template so
+ tones stay consistent.
+3. Compute the new key at the call site (the component that evaluates
+ pre-conditions) and pass it to `getClaimActionDisabledReasonText`.
+4. Extend
+ `src/utils/__tests__/claimActionDisabledReason.test.ts` to cover the
+ new key.
+
+### 3. When neither helper fits
+
+If your error surface is genuinely new (e.g. diverging-chain detection,
+on-chain simulation errors), create a new sibling helper in
+`src/utils/ErrorHandling.utils.ts` following the same shape:
+
+1. **Closed key union** — TypeScript exhaustiveness forces callers to
+ pick a copy.
+2. **One Record/Map** that owns _all_ English copy — no copy scattered
+ across components.
+3. **Pure functions** — no React, no hooks, no side effects. Easy to
+ unit-test.
+4. **Side-by-side tests** — colocated unit test in
+ `src/utils/__tests__/`.
+
+Do not duplicate copy inline in components; always go through a typed
+helper so future copy edits stay coherent.
+
+---
+
+## Shared Error State Components — Reference
+
+| Component | Mode | Purpose | Key props |
+| -------------------------------------------------- | ---- | --------------------------------------------------- | ------------------------------------------------------------------------- |
+| `showToast` (`@/utils/toast.util`) | 1 | Mutation feedback (success, error, loading, tx) | `showToast.{success,error,loading,transactionSuccess}(message, options?)` |
+| `CreatorProfileErrorState` (`@/components/common`) | 2 | Canonical inline error card for creator profile | `error?, onRetry?, isRetrying?, title?, message?` |
+| `SectionErrorBoundary` (`@/components/common`) | 3 | Catches sub-tree render throws with retry | `sectionName?, minHeight?, className?` |
+| `CreatorPageErrorBoundary` (`@/components/common`) | 4 | Catches creator-route render throws | none (wraps ``) |
+| `AppErrorBoundary` (`@/components/common`) | 4 | App-wide last-line-of-defense; full reload on retry | none (wraps ``) |
+| `TransactionRetryNotice` (`@/components/common`) | 5 | Persistent inline retry banner for failed trades | `title?, message, onRetry, retryLabel?, disabled?, className?` |
+| `TransactionFailureDrawer` (`@/components/common`) | 5 | Modal with error code, hash, and developer details | `open, onOpenChange?, failureDetails, onRetry?, onDismiss?` |
+| `NetworkMismatchBanner` (`@/components/common`) | 6 | Persistent "wrong network" warning | `className?` |
+

+[Adding a Page and Data Fetching](./adding-page-and-data-fetching.md)
+and [Shared Components](./shared-components.md).
+
+---
+
+## Worked Examples
+
+### Example A — Marketplace search list (read failure → Mode 2)
+
+The creator list inside the marketplace is critical content, so a query
+failure renders an inline state with retry. The rest of the page
+(hero, holdings, footer) stays interactive.
+
+```tsx
+// src/pages/LandingPage.tsx (excerpt)
+const { data: creators, isError, error, refetch } = useCreatorList();
+
+if (isError) {
+ const apiError = error as ApiError;
+ return (
+
+
+ );
+}
+
+return
+
+ );
+}
+```
+
+### Example C — Buy flow (mutation failure → Mode 1 + Mode 5)
+
+A trade mutation has both the prompt (toast), the persistent retry
+banner, and the detail drawer:
+
+```tsx
+// src/components/common/CreatorCard.tsx (excerpt)
+const buy = useBuyCreatorKey();
+
+const handleBuy = async (amount: number) => {
+ try {
+ await buy.mutateAsync({ creatorId, amount });
+ } catch (err) {
+ const apiError = err as ApiError;
+
+ // Mode 1: quick prompt
+ showToast.error(
+ apiError.status === 0
+ ? 'Network error. Check your connection.'
+ : apiError.message
+ );
+
+ // Mode 5: persistent banner + drawer for support detail
+ setFailure({
+ errorMessage: apiError.message,
+ errorCode: apiError.response?.code,
+ timestamp: Date.now(),
+ });
+ }
+};
+```
+
+---
+
+## Quick Reference
+
+| Question | Answer |
+| ----------------------------------------------------- | ----------------------------------------------------- |
+| Failure from a button click? | Toast (Mode 1), add drawer for on-chain trades |
+| Failure from `useQuery` that **is** the page? | Throw → Page boundary (Mode 4) |
+| Failure from `useQuery` that **enriches** the page? | Inline state with `refetch` (Mode 2) |
+| Component throws during render (not a query error)? | Wrap in `SectionErrorBoundary` (Mode 3) |
+| Wallet is connected but wrong chain? | `NetworkMismatchBanner` (Mode 6) |
+| User clicked "Cancel" on the wallet signature prompt? | `getSignatureErrorMessage` (Mode 1, specialised copy) |
+| New kind of wallet error? | Extend `WALLET_ERROR_COPY` |
+| New pre-action disabled reason? | Extend `ClaimActionDisabledReasonKey` + lookup |

+# Error Handling in React Query Hooks
+
+This guide documents the standard pattern for handling API errors in React Query hooks across this codebase. Follow it when writing new `useQuery` or `useMutation` hooks so error behavior is consistent and predictable for users.
+
+---
+
+## How Errors Flow In
+
+All HTTP requests go through the service layer (`src/services/`), which extends `BaseApiService`. The `handleError` method on that base class normalises every failure into an `ApiError` before it reaches the hook:
+
+| Raw failure | What you receive |
+| ------------------------------------- | ------------------------------------------------------ |
+| HTTP response with an error status | `ApiError(message, httpStatus, responseBody)` |
+| Request sent but no response received | `ApiError('Network error - check your connection', 0)` |
+| Unexpected non-HTTP exception | `ApiError(error.message, 500)` |
+
+One important exception: **401 + `TOKEN_EXPIRED`** is handled transparently by the Axios interceptor in `BaseApiService`. The interceptor silently retries the original request after refreshing the access token. If the refresh also fails the user is redirected to `/login`; the hook never sees this error.
+
+---
+
+## The `ApiError` Shape
+
+```ts
+// src/services/api.service.ts
+class ApiError extends Error {
+ status: number; // HTTP status code; 0 means no network response
+ response?: {
+ success: false;
+ message: string;
+ code?: string; // machine-readable code from the API, e.g. "INSUFFICIENT_BALANCE"
+ errors?: Array<{
+ field?: string; // present on 422 validation failures
+ message: string;
+ }>;
+ };
+}
+```
+
+Always cast the error to `ApiError` before inspecting it:
+
+```ts
+import { ApiError } from '@/services/api.service';
+
+onError: error => {
+ const apiError = error as ApiError;
+ console.log(apiError.status); // 0, 400, 403, 422, 500 …
+ console.log(apiError.message); // human-readable message from the API
+ console.log(apiError.response?.errors); // field-level details on 422
+};
+```
+
+---
+
+## Distinguishing Error Types
+
+### Network errors (`status === 0`)
+
+No response was received — the user is offline, the server is unreachable, or a timeout occurred. The user cannot fix the request payload; they need to retry later.
+
+```ts
+if (apiError.status === 0) {
+ showToast.error('Network error. Check your connection and try again.');
+ return;
+}
+```
+
+### 4xx — Client errors
+
+The request was received but rejected because of something the client sent. The message from the API is usually safe to show to the user.
+
+| Status | Cause | Typical UI response |
+| ------ | ------------------------ | ---------------------------------------------------- |
+| 400 | Malformed request | Toast with `apiError.message` |
+| 401 | Session expired | Auto-handled by the interceptor |
+| 403 | Insufficient permissions | Inline error or redirect |
+| 404 | Resource not found | Inline error state |
+| 422 | Validation failure | Inline field errors from `apiError.response?.errors` |
+| 429 | Rate limited | Toast with retry suggestion |
+
+### 5xx — Server errors
+
+The API itself failed. The user cannot fix the payload; they can only retry after the server recovers. Avoid showing raw server messages — use a generic fallback instead.
+
+```ts
+if (apiError.status >= 500) {
+ showToast.error('The server ran into a problem. Please try again shortly.');
+ return;
+}
+```
+
+---
+
+## Deciding: Toast vs. Inline Error vs. Error Boundary
+
+### Use a toast when
+
+- The failure came from a **user-initiated action** (mutation): buying a key, submitting a form, enrolling in a course.
+- The error **does not block the current view** — the page can still render usefully.
+- The fix is to retry or change input: one line of feedback is enough.
+
+```ts
+onError: error => {
+ const apiError = error as ApiError;
+ showToast.error(
+ apiError.status >= 500
+ ? 'Something went wrong. Try again.'
+ : apiError.message
+ );
+};
+```
+
+### Use an inline error state when
+
+- The error **blocks the primary purpose of the screen** — for example, the creator list failed to load so the page is empty.
+- The error contains **field-level detail** (422) that needs to map to specific form inputs.
+- The user needs to take **corrective action** (fix a field, switch networks) before retrying makes sense.
+
+```tsx
+const { data, isError, error } = useCreatorKeys(creatorId);
+
+if (isError) {
+ const apiError = error as ApiError;
+ return (
+
+ ;
+```
+
+`SectionErrorBoundary` renders a retry button that resets its own error state. Use it as a safety net around sections that fetch and render data together.
+
+---
+
+## `useQuery` Pattern
+
+React Query v5 removed the `onError` callback from `useQuery`. Errors surface through `isError` and `error` in the component. Keep the hook thin and handle the error at the call site:
+
+```ts
+// src/hooks/useCreatorProfile.ts
+import { useQuery } from '@tanstack/react-query';
+import { creatorService } from '@/services/creator.service';
+
+export function useCreatorProfile(creatorId: string) {
+ return useQuery({
+ queryKey: ['creator-profile', creatorId],
+ queryFn: () => creatorService.getProfile(creatorId),
+ staleTime: 30_000,
+ });
+}
+```
+
+```tsx
+// In the component
+import { ApiError } from '@/services/api.service';
+import { useCreatorProfile } from '@/hooks/useCreatorProfile';
+
+function CreatorProfileSection({ creatorId }: { creatorId: string }) {
+ const { data, isLoading, isError, error } = useCreatorProfile(creatorId);
+
+ if (isLoading) return
+ buyKey({ creatorId, amount })}
+ isBuying={isPending}
+ />
+
+ );
+}
+```
+
+---
+
+## Quick Reference
+
+| Condition | Check | UI response |
+| ------------------- | ------------------------------- | ------------------------------------------------------------ |
+| No network response | `apiError.status === 0` | Toast: "Network error. Check your connection." |
+| Server error | `apiError.status >= 500` | Toast: generic "something went wrong" message |
+| Validation failure | `apiError.status === 422` | Toast or inline: first item from `apiError.response?.errors` |
+| Other 4xx | `apiError.status >= 400` | Toast or inline: `apiError.message` (safe from the API) |
+| Read query fails | `isError === true` in component | Inline error state replacing the content area |
+| Render throws | Component boundary | Wrap with `` |

+# Editing Marketing Page Copy
+
+This guide is for non-technical contributors who want to suggest changes to the
+marketing page copy. You can edit the text directly on GitHub and open a pull
+request — no local development environment is required.
+
+## Where the copy lives
+
+All marketing page copy is in a single file:
+
+**`src/pages/MarketingPage.tsx`**
+
+The page is a single React component. Each visible section is a block of JSX
+with inline text. Use the table below to find the section you want to change.
+
+| Visible section on the page | Location in `MarketingPage.tsx` | What to look for |
+| ------------------------------- | ----------------------------------------- | ------------------------------------------------------------------------------ |
+| Page title ("Access Layer") | Hero / Title | `
Couldn't load the creator list
++ {apiError.status >= 500 + ? 'Something went wrong on our end. Please try again.' + : apiError.message} +
+ +
+ {apiError.status >= 500
+ ? 'Unable to load data. Please try again later.'
+ : apiError.message}
+
+ );
+}
+```
+
+### Use `SectionErrorBoundary` when
+
+- A **component throws during render**, not from an API call.
+- You want to **isolate a section** so one broken widget does not crash the whole page.
+- React Query's `throwOnError` option is enabled on a query.
+
+```tsx
+import SectionErrorBoundary from '@/components/common/SectionErrorBoundary';
+
+
+ {apiError.status >= 500

+ * End-to-end integration test for the buy flow (#642): from quantity input
+ * through simulated on-chain confirmation to the success toast and updated
+ * holdings cache.
+ *
+ * Mirrors the sell-flow E2E structure (see LandingPage.sellFlow.integration.test.tsx,
+ * #644): the wallet layer is the app's real demo wallet (react-query +
+ * useWallet, no hook mocks), so the holdings assertion exercises the real
+ * cache update path instead of a mocked one. Trading in this app is scoped
+ * to a single featured-creator panel (there is no per-card trade UI, and
+ * CreatorDetailPage has no trade panel), so "connect a mock wallet" here
+ * means rendering with a fresh QueryClient — the app's demo wallet address
+ * is used automatically and starts the featured creator at its baseline
+ * holdings.

+/**
+ * Integration test for holdings entry count after buy/sell sequence (#TBD).
+ *
+ * The holdings list should add an entry when a buy confirms for a new creator
+ * and remove it when all keys for that creator are sold. Additional keys for
+ * an existing creator must not produce a duplicate entry.
+ *
+ * Held positions are derived from the API response:
+ * index 0 → featuredHoldings (mutable via TradeDialog, starts at 3)
+ * index 1+ → DEMO_HELD_KEY_QUANTITIES (fixed per session)
+ *
+ * Flow (2 creators returned by the API):
+ * 1. Initial: featuredHoldings=3 (Creator A) + 2 keys (Creator B) → 2 entries
+ * 2. Sell all 3 keys of Creator A → 1 entry (only Creator B)
+ * 3. Buy 1 key of Creator A → 2 entries (A re-added, B still present)
+ * 4. Buy 2 more keys of Creator A → still 2 entries (no duplicate)
+ * 5. Sell all 3 keys of Creator A → 1 entry (only Creator B again)
+ *
+ * Acceptance criteria covered:
+ * - Entry added when a buy confirms for a new creator (step 3)
+ * - Entry not duplicated when additional keys are bought (step 4)
+ * - Entry removed when all keys for a creator are sold (steps 2, 5)
+ * - Entry count correct after each state change (all steps)
