How this service works
Publish a deterministic claim about a Base proxy and let the market try to break it. You assert that a contract's implementation slot held one address across a block range, fund a reward for whoever finds a block where it did not, and Tereno writes the claim onchain and adjudicates counterexamples by historical storage reads. If nobody collects before your deadline, you get a reproducible survival receipt: not an audit, but proof the claim stood in public with money on it.
Output
Returns an on-chain claim record including a unique claim ID, the asserted contract address, implementation slot address, block range, reward amount escrowed, deadline, and transaction reference. If the deadline passes without a successful counterexample, a survival receipt is returned as cryptographic proof the claim stood publicly with money on it. If a counterexample is found, the adjudication result and winner are returned.
Example use cases
Protocol upgrade stability proof
“We just upgraded our Base proxy contract and want public proof it stayed at implementation 0xDef...456 from block 20100000 to 20400000 — publish a Tereno claim with a 25 USDC reward and a 60-day deadline so anyone can try to disprove it.”
DeFi protocol pre-launch assurance
“Before our DeFi launch I want to assert on-chain that our proxy at 0xABC...789 never changed implementation between blocks 19800000 and 20000000 — fund the claim with 50 USDC and let the market try to break it for 14 days.”
Compliance audit trail
“I need a reproducible on-chain claim that our escrow contract proxy at 0x123...DEF held implementation 0x456...ABC from block 18500000 to 19000000 — put 5 USDC on it with a 7-day window as evidence for our compliance report.”
Technical details
Endpoint
POSThttps://www.tereno.xyz/api/v1/claimsWhen to prefer
Use this endpoint when you need a publicly verifiable, market-tested assertion that a Base proxy contract's implementation slot was stable across a specific block range — especially when a traditional audit isn't sufficient and you want cryptoeconomic proof via a funded public challenge. Prefer this over off-chain attestations or private audits when you need a reproducible survival receipt that anyone can independently verify.
Side effects
- Invalid or non-existent Base proxy contract address — claim rejected
- Block range invalid (start block > end block or blocks not yet finalized) — error returned
- Insufficient USDC balance or approval for reward escrow — payment fails
- Implementation slot address does not match historical chain data — claim may be immediately challenged
- Deadline too short or in the past — validation error
- Network congestion causing on-chain write delays
