Overview
Mixy is a Bitcoin mixer: bitcoin privacy service with several anonymization modes, automated order processing and a guarantee letter confirming the terms of each order.
You send coins to a one-time deposit address and receive the same amount, minus the fee, from the service's own reserves at the address you specify, which breaks the on-chain link between sender and receiver.
Privacy & KYC
No account, email or ID is needed: the only input is the address that should receive the mixed coins.
Every order comes with a PGP-signed letter of guarantee that can be verified against the published key.
Fees & limits
The service fee is 3–5% + 0.0007 BTC.
Orders from 0.002 BTC to 50 BTC are accepted.
Supported coins: BTC.
Verdict
Mixy does what a no-KYC mixer should: no signup, no identity data and a fixed, published fee, backed by a track record since 2022.
As with any custodial mixer, test with a small amount first and keep the order details until the payout arrives.
