How this service works
Detect upgradeable proxies on Ethereum via eth_getStorageAt - EIP-1967 (transparent, UUPS, beacon), legacy OpenZeppelin (zos), EIP-1822, Safe, EIP-1167 clones and EIP-7702 delegation - and return the implementation, admin and beacon addresses behind the proxy.
Output
Returns a JSON object containing the queried address, a boolean isProxy indicating whether a proxy pattern was detected, and when applicable: the proxy standard detected (EIP-1967 transparent/UUPS/beacon, EIP-1822, EIP-1167 minimal clone, legacy OpenZeppelin/zos, Safe, EIP-7702), the implementation contract address, the admin address, and the beacon address.
Example use cases
Auditing a DeFi protocol's upgradeability
“I need to audit Uniswap V3's factory contract at 0x1F98431c8aD98523631AE4a59f267346ea31F984 — can you check whether it's a proxy and reveal the current implementation address so I know if it can be upgraded?”
Verifying Safe multisig proxy setup
“Before I send funds to 0xd9Db270c1B5E3Bd161E8c8503c55cEABeE709552, can you tell me if it's a Safe proxy and what the singleton implementation address behind it is?”
Tracking implementation changes for a monitored contract
“I want to know the current implementation contract behind the USDC proxy at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — is it an upgradeable proxy, and if so, who is the admin?”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/eth/proxy/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to determine whether an Ethereum address is an upgradeable proxy and resolve the underlying implementation, admin, or beacon addresses. It supports a broad range of proxy standards (EIP-1967, EIP-1822, EIP-1167, OpenZeppelin legacy, Safe, EIP-7702) in a single call, making it ideal for smart contract auditing, security research, DeFi protocol analysis, and on-chain monitoring workflows where understanding contract upgradeability is critical.
Side effects
- Address is not a proxy — returns isProxy: false with no implementation/admin fields
- Invalid or malformed address — likely returns a 400 error or validation failure
- Address does not exist on Ethereum — may return isProxy: false or an error
- Network/RPC timeout when reading storage slots — transient 5xx error
- Rate limiting or payment failure (x402) — 402 Payment Required response
