Gnosis Chain On-Chain API

healthy 4,963 Subscribers

Live Gnosis Chain on-chain data as an API, built on the open Blockscout explorer. Gnosis Chain (chain id 100, formerly xDAI) is a long-running Ethereum-compatible network whose native currency is the xDAI stable token, so gas and balances are denominated in a dollar-pegged coin. Pull network stats (total blocks and transactions, native price, live gas), a gas oracle with slow, average and fast prices in gwei, the most recent blocks and full block detail by height or hash. Look up any address for its balance and contract status, any transaction by hash for its value, fee, status, sender and receiver, and any ERC-20 token by contract for its name, symbol, decimals, holders and USD rate. A universal search resolves addresses, tokens, blocks and transactions in one call. Real on-chain data, no key needed upstream. Ideal for Gnosis wallets, block explorers, gas trackers, DeFi dashboards and on-chain analytics.
