Supported blockchains and chain IDs for Zerion API
Reference list of mainnet and testnet blockchains supported by Zerion API, with chain IDs and coverage for tokens, transactions, and NFTs.
Building something that needs to stay current? Call the chains endpoint to fetch this list at runtime instead of hard-coding it. This page is regenerated from that same endpoint every day.
Zerion serves testnet data from a separate environment. Pass the X-Env: testnet header with your request to query these chains.
