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 the contract name, symbol, chain, proxy type, upgradeability flag, a list of privileged roles (each with role name, power description, holder address, and controller kind/risk), an overall worst-risk level, and a plain-English verdict string indicating whether the contract is one key away from compromise.
Example use cases
Pre-investment DeFi security audit
“Before I put money into this protocol, can you check if the contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum is one stolen key away from being drained? I want to know all the admin roles and whether they're controlled by a real multisig or just someone's wallet.”
Stablecoin issuer key security review
“Who has the power to mint or pause the USDT contract on Polygon — is it an EOA, a Safe, or does it go through a timelock? Pull the full role breakdown for 0xc2132D05D31c914a87C6611C10748AEb04B58e8F on chain 137.”
Protocol upgrade governance check
“I'm writing a report on Arbitrum DeFi governance. Can you tell me whether the proxy admin for 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 on Arbitrum (chain 42161) is a single key or a proper multisig with a timelock?”
Technical details
Endpoint
GEThttps://onekeyaway.appin60.com/api/control?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, structured assessment of who holds privileged on-chain powers for a specific DeFi contract — especially when evaluating protocol security risk before investing, integrating, or reporting. It covers 480 DeFi tokens across 15+ chains and specifically identifies whether control ends at a dangerous single EOA, a threshold Safe, or a timelock. Prefer this over generic block explorer lookups when you want a pre-interpreted risk verdict rather than raw on-chain data.
Side effects
- Contract address not found or invalid hex format returns an error
- Unsupported chain ID returns an error listing valid chains
- Contract not in the 480-token dataset may return limited or no role data
- Non-upgradeable contracts may return empty roles list
- Payment not received or insufficient USDC results in 402 response
