Noncustodial cryptocurrency mixers use publicly verifiable and transparent smart contracts to avoid any human intervention. Users can deposit their cryptocurrency into the mixer and assign a time interval to when they can withdraw it to a new crypto address. Users can confirm to the service that they deposited without exposing their transaction by using several cryptographic techniques in the withdrawal transaction.
