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