EVM Transaction Status

Look up a transaction on Base or Ethereum mainnet: status (success, failed, pending or not_found), block, confirmations, timestamp, from, to, ETH value, gas used, fee, method id and decoded ERC20 transfers with symbols and amounts. Useful to confirm that a payment arrived. Params: hash (0x transaction hash, required), chain ('base' default or 'ethereum').
