Xend

The marketing and waitlist site for Xend — a dollar account for everyday life. Hold dollars on your phone, send to anyone by username in seconds for cents, and fund from local currency.

Overview

This is a Next.js app (App Router) that serves the public Xend site: the landing page, the waitlist form, and legal pages (Terms of Service, Privacy Policy). Waitlist signups are stored in Postgres via Prisma and confirmed by email via Resend.

Tech stack

• Framework: Next.js 16, React 19, TypeScript
• Styling: Tailwind CSS v4, shadcn/ui (Radix primitives)
• Data: Prisma ORM + PostgreSQL (Supabase)
• Email: Resend + React Email
• Analytics: Vercel Analytics
• Hosting: Vercel

Getting started

1. Install dependencies

pnpm install

2. Configure environment variables

Create a .env.local file in the project root:

DATABASE_URL="postgresql://user:password@host:5432/database?schema=public"
DIRECT_URL="postgresql://user:password@host:5432/database"
RESEND_API_KEY="re_your_resend_api_key"

• DATABASE_URL — pooled Postgres connection string (from your Supabase project's Database settings)
• DIRECT_URL — direct (non-pooled) Postgres connection string, used for migrations
• RESEND_API_KEY — API key from your Resend dashboard

For local testing without a verified domain, Resend's default onboarding@resend.dev sender works out of the box. For production, verify your sending domain in Resend and update the from address in lib/emails/send-email.ts.

3. Run database migrations

npx prisma migrate dev

This applies the schema in prisma/schema.prisma — a single users table backing the waitlist (id, email, createdAt, isWaitlistUser).

4. Start the dev server

pnpm dev

The app runs at http://localhost:4030.
