Letter of Guarantee Verifier

Legitimate custodial mixers issue a signed letter of guarantee for every deposit. If there is ever a dispute, that letter is the only proof tying your deposit address to the operator, so verify it locally with this OpenPGP-powered tool before sending follow-up messages or relying on a refund.

Paste the letter, pick the service you used, and click verify. The verifier runs in your browser, does not use external APIs, and can be run offline; if the signature is invalid, stop immediately and contact the operator through official support channels. After verifying, store the letter offline together with the transaction ID.
