IPI Scan

Official source for the zero-dependency IPI Testnet explorer published at scan.ipi.io.

OpenSpec starts here

OpenSpec is initialized in openspec/. The first change captures the current production source without redesigning or extending it:

• publish-ipi-scan-source

The current source files are intentionally small and deployment-neutral:

• index.html powers the main IPI Scan interface
• evm.html provides the standalone IPI EVM diagnostic view
• explorer.css contains the responsive IPI Scan presentation
• explorer.js reads public CometBFT, Cosmos REST, and EVM JSON-RPC data
• dev-server.mjs serves the explorer locally and proxies public testnet APIs

The main explorer supports:

• dashboard and network health
• recent and paginated blocks
• block details and block transactions
• recent native transactions and transaction receipts
• native account balances, metadata, and recent activity
• bonded validators and validator details
• EVM transaction lookup
• EVM address balance, nonce, and bytecode lookup
• global search by block height (with or without #), native/EVM transaction hash, consensus/EVM block hash (with or without 0x), native account, validator, or EVM address
• ambiguous 64-character hashes are resolved against the live transaction and block RPC methods before navigation
• numbers, compact token amounts, and dates use the fixed en-US display locale instead of inheriting Polish or another browser locale

In production, chain data is read through same-origin /api/ routes configured by the deployment environment. No secret or write endpoint is required. The infrastructure configuration itself is not stored in this repository.

Local preview

Requires a Node.js version with built-in fetch.

From the repository root, run:

node dev-server.mjs

Then open http://127.0.0.1:8787/. The local server proxies requests to the current public testnet endpoints, so local verification uses live chain data.

Verification

The application has no compilation step. Verify the JavaScript and start the local server with:

node --check explorer.js
node --check dev-server.mjs
node dev-server.mjs

OpenSpec validation requires Node.js 20.19 or newer:

openspec validate publish-ipi-scan-source --strict --no-interactive

The complete historical EVM address transaction list and ranked account list remain dependent on a future PostgreSQL-backed indexer and are not implemented in this repository.
