How to use

  1. 01

    Run a verification

    Start from the Demo page or paste a record here. The verifier accepts a full FLINT artifact JSON or a compact JWS.

  2. 02

    Use the one-click handoff

    From the demo receipt, click Verify. You land here with the record filled in and checked automatically.

  3. 03

    Verify a record you received

    Paste the full exported artifact or a raw compact JWS string that starts with eyJ, then click VERIFY SIGNATURE.

  4. 04

    Try tampering with it

    Change a verdict, alter an amount, or flip one character, then verify again. FLINT rejects the record because the signature no longer matches.
