How this service works
Contract or wallet check on 16 EVM chains: deployed bytecode size, account kind including EIP-7702 delegated accounts, optional runtime bytecode.
Output
A JSON object containing the queried chain name and chain ID, the address checked, a boolean is_contract flag, an account_kind string (contract, eoa_or_empty, or eip7702_delegated_eoa), the deployed code size in bytes, optionally the runtime bytecode as hex (when full=true), and for EIP-7702 accounts the delegate_target contract address.
Example use cases
Smart contract deployment verification
“Can you confirm that 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 is actually a deployed contract on Ethereum and tell me its bytecode size?”
EIP-7702 delegated account detection
“Check if 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base is an EIP-7702 delegated account and if so, what contract does it delegate to?”
Cross-chain account type audit
“I need to know whether 0x4200000000000000000000000000000000000006 is a contract or an EOA on Optimism — also grab the full runtime bytecode if you can.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/chain/code?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to classify an EVM address as a contract, plain EOA, or EIP-7702 delegated account across any of 16 supported chains, especially when bytecode size or the delegation target matters. It is particularly valuable for detecting EIP-7702 smart accounts, which many generic RPC calls misclassify. Prefer this over raw RPC calls when you want structured, normalized output across chains without managing individual node connections.
Side effects
- Invalid or malformed address returns an error response
- Unsupported chain name or chain ID returns an error
- Address not found on chain returns code_size_bytes of 0 and is_contract false
- Network or RPC timeout may cause temporary unavailability
- EIP-7702 delegate_target only populated for delegated EOA accounts; null otherwise
