How this service works
Who deployed an EVM contract and when: creator address (named when known), creation transaction and date, contract name, verification, proxy type and implementation, and scam flag.
Output
A JSON object containing: the contract address and network, the deployer's address (with ENS name and named label if known), the creation transaction hash, the ISO 8601 creation date, the contract name, a verified boolean, proxy type (null if not a proxy), an array of implementation addresses (for proxies), a scam flag, and the data source (e.g. Blockscout).
Example use cases
Due diligence on a new DeFi token
“Before I ape into this token, can you check who deployed 0x532f27101965dd16442E59d40670FaF5eBB142E4 on Base — I want to know the creator address, when it was launched, if the contract is verified, and whether it's been flagged as a scam?”
Investigating a suspicious Ethereum contract
“There's a contract at 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum that someone sent me — can you find out who created it, when, and if it's a proxy or has any scam warnings?”
Research on a known protocol's deployment
“I'm writing up some research on Uniswap — can you look up the contract 0x1F98431c8aD98523631AE4a59f267346ea31F984 on Ethereum and tell me who deployed it, the exact creation date, the creation transaction hash, and whether it's verified?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/contract-creator?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to identify the original deployer of an EVM smart contract, verify its deployment history, or flag potential scams across Ethereum, Base, Arbitrum, Optimism, Polygon, or zkSync. Prefer it over block explorer UIs when you need machine-readable deployment metadata in a single API call. It is especially valuable when auditing unknown contracts, researching DeFi protocols, or building security tooling that needs creator provenance and proxy detection in one response.
Side effects
- Contract address not found on the specified network — returns null fields
- Invalid contract address format — returns validation error
- Network not supported — enum validation error if network is outside the allowed list
- Contract is unverified — verified field returns false, name may be null
- Proxy implementation not resolvable — implementations array may be empty
- External data source (Blockscout etc.) temporarily unavailable — may return partial or null data
