How this service works
Contract Check — Who owns it, is it a proxy, can supply still change. Read straight from bytecode and storage.
Output
Returns structured on-chain data including the contract owner address, whether the contract is a proxy (and proxy type if applicable), and whether the token supply is mutable (e.g. mintable, burnable, or fixed), all derived directly from bytecode inspection and storage slot reads.
Example use cases
Rug pull risk check before buying
“Before I ape into this token, check the contract 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Base — can the owner still mint new tokens or change the supply?”
Proxy upgrade risk for DeFi protocol
“Is the contract at 0x6B175474E89094C44Da98b954EedeAC495271d0F on Base a proxy? I need to know if someone can swap out the implementation.”
Ownership verification for token launch
“Who owns the contract at 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Robinhood chain, and is there any way the supply can still be inflated?”
Technical details
Endpoint
POSThttps://wafermap.xyz/v1/contract-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, trustless, low-level read of contract ownership and upgrade/mint risk without relying on third-party indexers or block explorers that may have stale or incomplete data. Ideal for pre-trade due diligence, automated token vetting pipelines, or any agent that needs to flag centralization or rug-pull risk signals directly from chain state.
Side effects
- Invalid contract address format returns a validation error
- Contract address not found on the specified network returns a not-found error
- Unverified or highly obfuscated bytecode may limit analysis accuracy
- Network parameter typo or unsupported network returns an enum validation error
- Rate limiting or payment failure returns a 402 or 429 error
