This repository is a community-maintained, curated registry of EVM-compatible blockchain networks. It contains thousands of JSON files under `_data/chains/`, each defining a chain's metadata: RPC endpoints, native currency, explorers, icons (IPFS CIDs), status (active/deprecated/incubating), parent L2 relationships, and feature flags. The dataset is the primary asset, designed for consumption by wallets, dApps, block explorers, and infrastructure tooling that needs up-to-date chain information. Beyond the data, the repository includes a Kotlin-based processor that validates all chain definitions (schema compliance, icon size/format, IPFS retrievability, ENS address checks) and produces aggregated `chains.json` and `chains_mini.json` outputs. A published Kotlin model library (`model/`) and an HTTP loader (`httpsloader/`) enable programmatic access. CI pipelines enforce formatting, schema validation, and per-PR checks. The project is hybrid: its core value is the dataset, but it also delivers a well-engineered application layer for validation, aggregation, and distribution. The registry answers questions like 'What RPC endpoints are available for chain X?', 'What is the native currency of chain Y?', 'Which chains are L2s of Ethereum?', and 'What explorers support EIP3091?'. It serves as a single source of truth for EVM chain metadata, reducing fragmentation across the ecosystem.
This repository is the canonical metadata registry for the Initia blockchain ecosystem. It contains structured JSON files describing chains (Cosmos SDK L1 and L2 minitias), their asset lists with full provenance traces (IBC, OP-bridge, wrapped), profile metadata for ecosystem projects, and error codes for Move smart contracts. The data is validated against JSON Schema (chain.schema.json, assetlist.schema.json, profile.schema.json) via GitHub Actions, ensuring consistency and correctness. The registry also includes TypeScript packages that export aggregated data and auto-generated Zod schemas for runtime validation, as well as an API build system that transforms and deploys the data to a CDN. While the core is data, there are significant application components: npm packages, validation workflows, and utility scripts for syncing images and computing IBC denoms. The repository solves the problem of discovering chains, assets, and bridge routes within the Initia network, serving wallets, explorers, and frontends.
