PQ Attest

Overview

PQ Attest writes a fingerprint of a confirmed transaction onto Algorand and returns a proof anyone can check. The source transaction can come from Algorand, Base, Solana, Bitcoin, Ethereum, and a set of other networks. The attestation itself always lands on Algorand MainNet.

A new attestation costs 0.001 USDC, paid through x402. Checking a proof is free. The public site is pqattest.com. The numbers on this page come from the project's public stats file.

How it works

The service fetches the transaction, hashes a canonical record of it, and submits a 0 ALGO transaction whose note commits to that hash. The proof bundle is signed with ML-DSA-65. The note is authorized with a Falcon-1024 account.

The attestation is on Algorand. Payment can settle on Algorand, Base, or Solana, independent of the source chain.
Verification does not depend on this site staying online. The proof and the on-chain note can be checked on their own.
