HALOWERK kettenwerk Upgrade Risk Analyzer
x402
HALOWERK kettenwerk Upgrade Risk Analyzer is a paid API for AI agents from kette.halowerk.com, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-11).
Analyzes proxy upgrade risk for a smart contract by detecting proxy patterns, resolving the admin, and checking whether the admin is a multisig or timelock with meaningful delay.

How this service works
Upgradeability alone is not a finding — every serious protocol is upgradeable. The finding is who holds the key and how much warning holders get. This endpoint reads the proxy pattern from the EIP-1967 slots, the clone bytecode or an implementation() call, resolves the admin, checks whether that admin is a multisig by asking it for its threshold and signer count, and checks whether it is a timelock by asking for getMinDelay() or delay() — a timelock with a delay of zero is not a timelock and is
Output
Returns the detected proxy pattern (EIP-1967, clone, or implementation() call), the resolved admin address, whether the admin is a multisig (with threshold and signer count), whether the admin is a timelock (with delay in seconds), and an overall upgrade risk classification indicating how much control and warning token holders actually have.
Example use cases
Audit DeFi protocol upgrade governance
“Before I put money into this yield protocol, can you check if the proxy at 0x7Fc66500c84A76Ad7e9c93437bFc5Ac33E2DDaE9 on Ethereum is controlled by a proper multisig or timelock — or if a single dev can just silently upgrade it?”
Validate timelock delay before depositing
“I'm looking at a lending protocol on Arbitrum at 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC6 — is the upgrade admin actually a timelock with a meaningful delay, or is the delay set to zero making it basically meaningless?”
Compare governance risk across chains
“Can you assess the upgrade risk for the contract 0x4200000000000000000000000000000000000042 on Optimism? I need to know the proxy type, who the admin is, and whether it's a real multisig with multiple signers.”
Technical details
Endpoint
POSThttps://kette.halowerk.com/contract/upgrade-risk?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to assess the governance and upgrade security of a specific smart contract proxy — particularly before investing in or integrating with a DeFi protocol. Prefer this over generic contract scanners when you specifically need to know whether the upgrade key is held by a meaningful multisig or a timelock with real delay, rather than just whether the contract is upgradeable at all.
Side effects
- Address is not a proxy contract — returns no proxy pattern detected
- Contract address is not valid or does not exist on the specified chain
- Chain is not in the supported enum — returns validation error
- Admin address resolution fails due to RPC issues — returns partial result
- Timelock or multisig interface not recognized if using non-standard implementations
- Rate limiting or payment failure returns 402 or 429
