##### Spending from post-mix wallet
##### Additional Anonymity Set
A post-mix wallet SHOULD provide every means to avoid merging outputs in a way which destroys the benefits of the achieved CoinJoin and diminishes privacy.
A post-mix wallet MAY offer to make a user's first purchase to be a regular CoinJoin transaction, without the usage of fixed denomination so additional anonymity set can be achieved. In this CoinJoin every input transaction is the same denomination, therefore an observer will not be able to tell who wanted to pay who, it can only figure out which change belongs to which active output.
A post-mix wallet SHOULD provide the following means of spending outputs (from most important to least important):
- [Stowaway](https://samouraiwallet.com/stowaway): also known as [PayJoin](https://joinmarket.me/blog/blog/payjoin/).
- STONEWALLx2: 2-wallet STONEWALL.
- [STONEWALL](https://samouraiwallet.com/stonewall): single-wallet STONEWALL.
- any other type spend: only permitted when a single-wallet STONEWALL is not possible.
Outputs from different denominated pools may be used.
