Returns deployment metadata for each supported chain, including contract addresses for the multicall and transfer delegate contracts. Use this endpoint to look up the correct contract addresses for building transactions or verifying approvals on a specific chain.

Reference

Response

Returns an object keyed by chain name, where each chain contains a deployments object with contract addresses.
