Verify a Receipt

Check the bridge's signed swap receipts against its own promises. All cryptography runs locally in your browser — nothing you paste here is sent anywhere.

Don't want to trust this website either? Download umbra-verify.html — a single self-contained file you can open from your own disk. It makes zero network requests and verifies the same receipts, checkpoints, and Merkle inclusion proofs.

The API only supplies the data; every signature check happens client-side.

If set, every signature must be made by exactly this key. Without a pin, verification proves internal consistency but not who signed. Stored only in your browser.
