How this service works
Live feed of proxy upgrades, ownership transfers, pauses and role changes across 911 contracts of 85 DeFi protocols on Ethereum, Base, Arbitrum and OP.
Output
Returns a JSON object containing: a risk level (e.g. low/medium/high), the chain, proxy type (e.g. oz-legacy), current implementation address, upgrade authority type (e.g. EOA or multisig), full upgrade history with transaction hashes and timestamps, a plain-English summary of admin risk, and a list of findings each with severity and descriptive text.
Example use cases
Audit proxy upgrade authority before investing
“Before I deposit into this protocol, check the admin risk for 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 on Base — is it upgradeable, and is the upgrade key controlled by a single wallet or a multisig?”
Alert on recent ownership transfers in a DeFi protocol
“I want to know if there have been any ownership transfers or proxy upgrades on 0xc3d688B66703497DAA19211EEdff47f25384cdc3 on Arbitrum recently — pull the full admin-change history and flag any high-severity findings.”
Screen a new token contract for admin risks
“Can you run an admin-watch risk check on this Ethereum contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and tell me the overall risk level, proxy type, and any pause or role-change findings I should know about?”
Technical details
Endpoint
GEThttps://admin-watch.quietworklabs.workers.dev/x402/verdict?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, pre-indexed admin risk intelligence for DeFi contracts across Ethereum, Base, Arbitrum, and Optimism — particularly proxy upgrade history, ownership authority type, and pause mechanisms. It covers 911 contracts across 85 protocols, so it is far faster and cheaper than running your own on-chain indexing. Prefer it over raw RPC calls or block explorers when you need a parsed risk verdict rather than raw event logs, and when the contract is likely to be in its curated watchlist.
Side effects
- Contract address not in the monitored set of 911 contracts — returns no data or a 404-style error
- Invalid or malformed contract address — request rejected
- Chain not supported or not specified correctly — may return empty or error
- Payment not settled via x402 protocol — request blocked with 402 Payment Required
- Transient upstream node or indexing outage — may return stale or partial data
