Verify a receipt without trusting us
Every Queldrex decision comes with a signed Trust Receipt. Paste one below and this page checks its Ed25519 signature against the key the receipt carries, right here in your browser. Nothing is uploaded. If the signature holds, the receipt is genuine and unaltered, whether or not you trust Queldrex or this page.

How this works
The signature is checked against the receipt's own embedded public key, so the proof needs nothing from us. The one optional step that contacts our servers is confirming that key is the one Queldrex publishes at /api/trust/pubkey, and it never affects the signature result. Prefer the command line? The zero-dependency @queldrex/verify does the same check offline, and the format is documented in the open receipt spec.Have a receipt ID instead of the JSON? Open /verify/receipt/{id} to look it up, or fetch /api/trust/receipt/{id} and paste the result here.
