# IOTA EVM Chain API
> Live on-chain data for IOTA EVM — the EVM Layer 1 of the IOTA network — via its public Blockscout explorer (no wallet, no key). The stats endpoint returns chain-wide totals (blocks, transactions, addresses, average block time, gas used); gas gives the current gas-price oracle (slow/average/fast). Blocks lists the latest blocks, and a single block resolves by height or by hash with its transaction count, gas, validator and timestamp. The address endpoint returns any account's IOTA balance, nonce, contract flag and token holdings; transaction resolves a tx by hash with its from/to, value in IOTA, fee, status and block. The token endpoint returns an ERC-20 token's metadata (name, symbol, decimals, total supply, holders) by contract address, and search runs a universal lookup across addresses, tokens, blocks and transactions. Gas, balances, values and fees are denominated in IOTA, the native coin. Real on-chain data straight from the explorer, refreshed every call — no key. 9 endpoints. For multi-chain coverage combine with the other oanor chain APIs (Ethereum, Base, Arbitrum and more).
