Everything you can verify about our bitcoin mixer.

The signed receipt from every mix.

Before you send a single satoshi, we hand you a plain-text letter listing your deposit address, the fee, every payout, and the amount going to each one. It's signed with the same key we've used since 2020.

That letter is your proof. If a payout doesn't show up when we said it would, the signature ties us to what we promised — there's nothing to argue about.

Save both the plain text and the PDF version. Both check against our key the same way.

The Anonymixer PGP key.

One key. Same one since we turned the service on in 2020. If it ever changes, we'd tell you in the warrant canary — and even then, we'd want you to be suspicious.

How to verify a signed letter

1. Get the public key from the onion address below (or a keyserver you trust).
2. Import it: gpg --import anonymixer-pubkey.asc
3. Check the fingerprint matches what's on this page. If it doesn't, stop.
4. Verify the signed letter: gpg --verify letter.txt.asc letter.txt
5. Look for "Good signature" and the same fingerprint. Anything else means don't trust it.

Warrant canary.

Every quarter, on the 15th of the first month, we publish a signed statement saying no one's leaned on us during the period. If you show up here on the 16th of April, July, October, or January and don't see a fresh one — treat that as a red flag.

We mirror the canary to three locations we don't control. If someone forced us to fake it here, they'd have to fake it in all four places. That's the point.

Tor onion address.

Same v3 onion since April 2021. Same interface as clearnet, same features, no captcha, no reduced functionality. Your IP never touches our servers this way.

First published April 2021 · Rotated: never · Verified in every quarterly canary.

If someone tells you the onion has changed, check the warrant canary. If it hasn't been mentioned there, it hasn't changed. That's a rule we don't break.

What to do if something's wrong.

If a payout hasn't arrived after its release window — and only after — PGP-encrypt the signed letter and send it to the dispute address. Include the session ID in the subject. We answer within 72 hours in the vast majority of cases.
