Chain Registry Types (chainregistry)

The chainregistry package defines strongly-typed Go structs for Cosmos chain-registry data (chain.json and assetlist.json).

For full API details, see the chainregistry Go package documentation.

When to use​

  • Parse chain-registry JSON into typed values.
  • Build tooling that reads chain metadata (APIs, fees, staking tokens, assets).
  • Validate or transform registry documents before writing them back.

Key APIs​

  • type Chain struct{ ... }
  • type APIs struct{ ... }
  • type APIProvider struct{ ... }
  • type AssetList struct{ ... }
  • type Asset struct{ ... }
  • type Fees struct{ ... }
  • type Staking struct{ ... }
  • type Codebase struct{ ... }
  • type ChainStatus string
  • type ChainType string

Common Tasks​

  • Decode chain.json data into a Chain value and inspect RPC/REST metadata.
  • Decode assetlist.json into AssetList to access denom units and logo URIs.
  • Use enum-like types (ChainStatus, NetworkType, ChainType) to keep metadata checks explicit.
