How this service works
Free check: who can upgrade, mint or pause a smart contract. An EOA, a 1-of-n Safe, a real multisig, or a timelock. Results from 480 DeFi tokens.
Output
Returns a JSON object with an 'ok' status flag, a 'verdict' string classifying the controller type (e.g. 'MULTISIG 5-of-10', 'EOA', 'TIMELOCK'), and a 'safe' object containing the owner addresses array, signing threshold, guard address, and active modules for the controlling account.
Example use cases
Pre-investment DeFi protocol audit
“Before I ape into this yield farm, can you check who controls the upgrade key on their contract at 0xAbCd1234... on Arbitrum (chain 42161)? I want to know if it's a real multisig or just a single EOA that could rug me.”
Token listing security due diligence
“We're listing a new token on our exchange and need to verify its contract security — check 0x7Fc66500c84A76Ad7e9c93437bFc5Ac33E2DDaE9 on Ethereum (chain 1) and tell me whether the mint and pause functions are controlled by a multisig or a single wallet.”
DeFi dashboard risk monitoring
“Can you run a security check on the Aave V3 pool contract at 0x87870Bca3F3fD6335C3F4ce8392D69350B4fA4E2 on Ethereum (chain 1) and tell me the ownership structure — specifically whether it's a timelock, multisig threshold, or just a single key?”

Endpoint
GEThttps://onekeyaway.appin60.com/api/safe?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, structured classification of a DeFi smart contract's admin key security posture — specifically whether critical functions (upgrade, mint, pause) are controlled by a single EOA, a Safe multisig, a timelock, or a higher-threshold multisig. It covers 15 major chains and returns a human-readable verdict alongside raw ownership data, making it ideal for pre-investment audits, token listing due diligence, and automated risk monitoring dashboards. Prefer it over general blockchain explorers when you need a direct, opinionated security verdict rather than raw transaction data.
Side effects
- Invalid contract address format returns an error
- Unsupported chain ID returns an error or empty result
- Contract not found on specified chain returns null or error
- Contract has no recognized ownership pattern may return ambiguous verdict
- Network timeout or RPC failure may cause delayed response
- Non-DeFi contracts may return incomplete ownership data
