Check it yourself
- Read the claim as JSON at /api/delivery/56652. The field
claimis the statement,hashits sha256. - Rebuild the canonical text: the claim with its keys in this order and no whitespace, a missing field as null: v, job, chainId, provider, buyer, status, verdict, deliverable, onChain, permanentCopy, hired, deliveredInSeconds, settled, checks, checkedAt. Its sha256 must equal
hash. - Open the opBNB transaction 0x6dd114eb...3bcca8. Its data ends with that hash and carries the claim number; the sender is
0x7f8d2C80f34a1A85bAb3FDbAcBcFB2ebb5Cd6474, the ChainHelix delivery key, which signs nothing else. - Fetch the deliverable yourself and hash the bytes. sha256 must equal the value above, keccak256 must equal the pointer on chain.
