A community-maintained dataset of metadata for EVM-based blockchain networks, keyed by CAIP-2 chain identifiers. It provides chain IDs, RPC endpoints, native currency info, explorers, and icons, aggregated into downloadable JSON files at chainid.network.
Use cases
- look up the chain ID for an EVM network
- get RPC endpoints and currency metadata for a blockchain
- add a new EVM chain to a wallet
- avoid chain ID collisions when launching a network
- download a full list of EVM chains as JSON
When to choose
- you need canonical EIP-155 chain IDs and network metadata for wallets or dapps
- you want aggregated, up-to-date chain data via a simple JSON endpoint
When to avoid
- you need non-EVM chain data like Bitcoin or Solana
- you need real-time RPC health or node status monitoring
