# Immutable zkEVM API
> Live Immutable zkEVM on-chain data via Blockscout. Immutable zkEVM is a gaming-focused Ethereum L2; gas and balances are in IMX. Network stats, gas prices, latest blocks, a block by height or hash, address detail with IMX balance, a transaction by hash, ERC-20 token metadata and a universal search across addresses, tokens, blocks and transactions. Real data, no key.
