Signed proof documents for official exchange rates

Keep source attribution, selected date, document id, payload hash, and public verification together.

Verification

Verify an exchange rate proof PDF

Enter the FXProof document id and payload hash from the PDF header. Verification checks the proof payload metadata, not the byte hash of the signed PDF file.

How proof verification works

FXProof public verification uses document id + payload_hash. It checks whether the stored proof payload metadata matches the submitted values; it does not decide legal, tax, audit, regulator, court, or recipient acceptance.
