This is a feature release that brings major changes to Phoenix: taproot channels and support for multiple wallets.

Changes

Taproot channels

Lightning channels created by Phoenix now use taproot, meaning that they are cheaper (by about 15%), and more private, since they cannot be distinguished from regular transactions. Beforehand, it was easy for third parties to detect if a Bitcoin transaction was related to a Lightning channel operation.

Existing channels are automatically transformed to taproot channels when they perform an on-chain operation. For example, if they receive a Lightning payment that needs to expand the channel (splice-in) ; or if they send funds on-chain (splice-out).

Newly created channels are always taproot channels.

Multi-wallets

You can now manage multiple wallets on the same instance of Phoenix. To help distinguish between wallets, you can give a name and a photo to your wallets. Lock/Spending PIN codes are specific to a wallet.

To create a new wallet or switch to another one, go to Settings and tap on the Wallet button in the top section.
