Coinjoins are available to use for privacy !

Types of CoinJoins
There are two types of CoinJoins available in the app that can be used via QR with existing Samourai users and either QR or Soroban with Ashigaru users. There is no service fee to be paid for either of these transaction types, only the transaction miner fee paid by the sender, or shared between the sender and collaborator to ensure transaction entropy.
Stowaway:
A type of “PayJoin” between supporting wallet users that looks like a typical Bitcoin transaction with two outputs, yet has inputs that are not from a single entity. Additionally input UTXOs are always from different transactions. Together with the amount transacted not being viewable on the blockchain in any output, this results in multiple possible interpretations.
STONEWALLx2:
This is identical on chain to a STONEWALL (aka “Private Spend” in Sparrow) that is created by a single user, yet is a transaction where a supporting wallet sender and collaborator work together to spend to an external wallet address or PayNym. This is useful for sending to recipients that are offline or don’t have a wallet that supports CoinJoins. This transaction always has four outputs; a spend, a decoy and two change outputs. Inputs are always UTXOs from different transactions and always involve both the sender and collaborator. There is no single, certain interpretation for an outside observer, or the recipient to make.
