Platon Chainlist

---

name: platon-chainlist description: Query Chainlist data and return a validated summary for a requested chain and network such as PlatON, Avalanche, or Ethereum. Use when a user asks for inputs like dev info, mainnet info, avalanche test, ethereum mainnet, or similar chain-plus-network endpoint lookups.

Chainlist Query

Overview

Query https://chainlist.org/rpcs.json for the requested chain and network, then format the result for the user. Use the bundled TypeScript script for deterministic parsing instead of manually scanning the JSON.

Prerequisites

Require Node.js 24+ because the script uses the built-in fetch and WebSocket APIs.

Workflow

1. Run scripts/lookup_chain.ts with the user's query text.
2. Let the script fetch Chainlist directly unless the task provides a local JSON file.
3. Return the summary view for the requested chain and network.

Commands

Use these forms:

node scripts/lookup_chain.ts dev info
node scripts/lookup_chain.ts testnet info
node scripts/lookup_chain.ts mainnet info
node scripts/lookup_chain.ts main info
node scripts/lookup_chain.ts avalanche test
node scripts/lookup_chain.ts avalanche test --chainid 43113
node scripts/lookup_chain.ts avalanche mainnet
node scripts/lookup_chain.ts ethereum mainnet
node scripts/lookup_chain.ts platon dev --chainid 20250407

Supported network aliases:

• dev, test, testnet, devnet
• mainnet, main

Optional filters:

• --chainid <id>: require the selected Chainlist entry to match the exact chain ID

Default Chain Info

Official site:

• https://www.platon.network

Mainnet defaults:

• Explorer: https://scan.platon.network/
• Explorer: https://blockscout.platon.network/
• HTTP RPC: https://openapi2.platon.network/rpc
• WebSocket RPC: wss://openapi2.platon.network/ws
• Chain ID: 210425 (0x335f9)

Devnet defaults:

• Explorer: https://devnet3scan.platon.network/
• Explorer: https://devnet3blockscout.platon.network/
• HTTP RPC: https://devnet3openapi.platon.network/rpc
• WebSocket RPC: wss://devnet3openapi.platon.network/ws
• Chain ID: 20250407 (0x134ff27)

Faucet:

• Devnet faucet: https://devnet3faucet.platon.network/faucet

Notes

Only the info command is supported.

If no chain name is provided, default to platon.

If --chainid is provided, it is an additional exact-match filter after chain name and network selection.

Validate HTTP RPC endpoints by calling eth_getBlockByNumber. Validate ws / wss RPC endpoints with a WebSocket JSON-RPC request using the same method.

If multiple test/dev entries exist for the same chain, prefer the best-ranked entry for the requested network and then the largest chainId.

If the user needs machine-readable output, use --format json.
