The Cosmos Chain Registry is a centralized repository of structured metadata for Cosmos SDK-based blockchains and their assets. It provides standardized JSON schemas (chain.json, assetlist.json, versions.json) that describe chain configurations, token metadata, and Inter-Blockchain Communication (IBC) channel information. This registry enables developers, validators, and applications to easily discover and interact with Cosmos networks. ## Key Features - **Chain Metadata** — Standardized `chain.json` files containing essential data like chain ID, bech32 prefix, RPC/API endpoints, and staking parameters. - **Asset Lists** — `assetlist.json` files that map denoms to metadata (name, symbol, images, social links) for tokens, including IBC assets. - **IBC Data** — JSON files describing IBC channel connections between chains, useful for relayers and cross-chain applications. - **Version History** — Optional `versions.json` tracking chain upgrade history, binaries, and dependencies. - **Tooling Integration** — Provides npm packages, Rust crates, and public APIs for programmatic access to registry data. ## Philosophy The registry follows a community-driven, schema-first approach to standardize blockchain metadata, with the long-term vision of migrating to an on-chain representation via the Cosmos Hub.
