How this service works
EVM Contract Introspection (optimism). Optimism contract introspection: contract vs wallet (incl. EIP-7702 delegation), bytecode size, proxy detection (EIP-1967 and legacy OpenZeppelin slots) and ERC-20 name, symbol, decimals, total supply.
Output
Returns on-chain contract introspection data for the specified Optimism address, which may include bytecode, contract type indicators, deployment metadata, ABI fragments, or other EVM-level contract details available from the Optimism network node.
Example use cases
Verify deployed contract on Optimism
“I need to check if the address 0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45 is actually a deployed contract on Optimism and see what its bytecode or ABI looks like.”
Audit token contract before trading
“Before I interact with this DeFi protocol, can you pull the contract info for 0x7F5c764cBc14f9669B88837ca1490cCa17c31607 on Optimism so I can verify what I'm dealing with?”
Monitor contract metadata for dApp
“I'm building a dashboard — can you fetch the contract introspection data for 0x1F98431c8aD98523631AE4a59f267346ea31F984 on Optimism so I can display its details to my users?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/optimism/contract/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need contract introspection data from the Optimism (OP Mainnet) L2 network. Prefer this over generic Ethereum mainnet endpoints when working with Optimism-native or bridged contracts. Choose this over the sibling Arbitrum endpoint when the contract is deployed on Optimism. Useful for agents that need to verify, audit, or display contract-level on-chain data without running their own Optimism node.
Side effects
- Invalid or malformed contract address returns an error
- Address is an EOA (externally owned account), not a contract — may return empty bytecode
- Contract not deployed on Optimism (wrong network) — returns null or empty result
- Network connectivity issues to Optimism RPC node — timeout or 503 error
- Rate limiting or payment failure — 402 or 429 response
