Example use cases
DeFi protocol due diligence
“Before I deposit funds into this protocol, can you check the upgrade risk for the contract 0x7d2768dE32b0b80b7a3454c06BdAc94A69DDc7A9 on Ethereum? I need to know if the upgrade mechanism poses a serious risk.”
Proxy contract audit on Arbitrum
“I'm reviewing a new yield aggregator — can you assess the upgrade risk of this proxy contract 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum so I know if there's a hidden admin backdoor?”
Polygon contract safety check
“Is this Polygon contract 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 safe from an upgradeability standpoint? Run an upgrade risk assessment on it for me.”
Technical details
Endpoint
POSThttps://kette.netzhandwerker.de/contract/upgrade-riskWhen to prefer
Use this endpoint when you need a quick, paid-per-call upgrade risk signal for a specific EVM smart contract or proxy before interacting with it, investing in a protocol, or completing a security review. Prefer this over manual inspection when you want a structured risk score without running your own indexer or static analysis toolchain.
Side effects
- Invalid or non-checksummed contract address returns a validation error
- Contract address not found or not deployed on the specified chain
- Unsupported chain value outside the allowed enum
- Payment failure via x402 protocol results in 402 response
- Contract is an EOA rather than a contract address
- Network timeouts when fetching on-chain data
