Registry

The Recoil Link registry is a public GitHub repository holding:

  • chains/<name>/metadata.yaml: chain id, domain id, RPC URLs, block explorers, native token, block times. Around 350 chains.
  • chains/<name>/addresses.yaml: Recoil Link's deployed contracts, only for the chains Recoil Link runs on (Networks).

rlink, the SDK and the agents read it by default. Tools can fetch it directly:

The chain metadata is inherited from the Hyperlane registry (MIT). Hyperlane's own deployment addresses have been removed, so Recoil Link tooling never uses Hyperlane's contracts by accident.
