TRUSTLESS CHECK

[ VERIFY A RECEIPT ]

Paste an attestation digest, a report sha256, or a transaction signature. We recompute the canonical payload and check the on-chain memo — verification that doesn't trust this website.

1 · recompute
sha256 over the canonical receipt fields — same bytes, same digest, or it didn't happen.
2 · check the chain
the memo cachorro:v1:<digest> must exist on-chain — anchored, not claimed.
3 · watch staleness
program upgraded? the digest stops matching and the receipt expires itself.
