#chains

A live directory of every EVM-compatible blockchain, keyless. Look up any chain by its chain ID or by name and get its native currency, public RPC endpoints, block explorers, info URL, faucets and testnet flag; search the 2,600+ networks; or just get a chain working public RPC URLs. The networks / chain-ID layer for wallets, dapps, RPC routers, block explorers and multi-chain tooling. Live, nothing stored beyond a short cache. Backed by the open chainid.network (ethereum-lists/chains) registry.

Live DeFi total-value-locked per blockchain as an API, streamed from the DefiLlama chains feed. For every chain DefiLlama tracks: the dollar value of assets locked in its DeFi protocols, its native token symbol, and its share of all DeFi value (dominance), plus 7-day and 30-day change for a chain. Rank the blockchains by how much capital they hold, drill into one chain, read the total DeFi market and its leader, or search. The blockchain-level view of where DeFi capital lives. Live, no key. Distinct from protocol-level TVL, fees, DEX-volume and yield APIs — here the entity is the chain, not the protocol.
