PQ Attest turns transaction IDs into proof bundles
A service that fingerprints confirmed transactions from multiple chains, records those fingerprints on Algorand, and returns signed proof bundles.
- For
- Developers and agents needing verifiable transaction records
- Worth noticing
- The sample bundle includes source and attestation transaction IDs, a SHA-256 fingerprint, an Algorand round, and an ML-DSA-65 signature.
Field notes
The documented flow starts with an already-confirmed transaction ID: a requester completes x402 payment, then resubmits that ID. The page says it fingerprints the full record, including inner transactions and confirmation details, and writes the fingerprint to Algorand; a shortened JSON example exposes the source ID, attestation ID, ledger round, public key, and ML-DSA-65 signature. It explicitly notes that there is no separate state proof.
