8 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
Is this address a contract, and what code does it hold? Returns isContract, deployed bytecode size, and the keccak-256 hash of the bytecode (stable fingerprint for comparing deployments) on Ethereum, Base, Polygon, Arbit...
Is this address a contract? Bytecode size, EIP-1967 proxy implementation and EIP-7702 delegation. Default chain Base; prefix another: ethereum:, arbitrum:, optimism:, polygon:, bsc:. $0.01 per call.
Tells whether an address is a smart contract or a plain wallet, and how big its bytecode is. A cheap safety check before sending funds. Via eth_getCode.
Check whether a Base mainnet address is a contract via eth_getCode - returns bytecode size, zero for an externally-owned account.
🆕 What sits at a Base address: contract or plain wallet, and if a contract, whether it declares ERC-721 or ERC-1155 via ERC-165 or carries the ERC-20 shape, plus name, symbol, decimals and code size. Interface support i...
Is this Ethereum address a contract or a wallet? EOA, EIP-7702 delegated wallet or smart contract, bytecode size, ETH balance and ERC-20 symbol. Safety check before sending funds.
Is this address a contract or a wallet? Checks any Base address: EOA, EIP-7702 delegated wallet or smart contract, bytecode size, ETH balance and ERC-20 symbol. Cheap safety check before sending funds.
Determine whether an address on Base is a contract or an externally owned account. POST {"address":"0x..."} and receive isContract, the bytecode size in bytes and its keccak-256 hash. Useful before sending funds to an un...
