README

Phoenix Logo

Phoenix is a Bitcoin wallet developed by ACINQ, that allows you to send and receive bitcoin securely over the Lightning Network. It is self-custodial, which means that you hold the keys of the wallet. It provides a simple and clean UX. Thanks to native Lightning support, payments are faster and cheaper.

🚨 This wallet is self-custodial. It means that, when creating a new wallet, a 12-words recovery phrase is generated. Only you have it. It is your responsibility to make a backup of that recovery phrase. It gives full access to your funds, so do not share it with anyone. If you lose the recovery phrase, your funds are lost.

Download

Phoenix is available for Android and iOS:

for iOS: on the App Store - requires iOS 15+.
for Android: on Google Play, or get the APK from the releases - requires Android 8+.

Build and test Phoenix

Phoenix is separated in 3 modules:

phoenix-shared: business logic written in Kotlin, shared between the iOS and the Android applications. Uses lightning-kmp for everything Lightning/Bitcoin related.
phoenix-android: the UI for the new Android application, written in Kotlin and Jetpack Compose.
phoenix-ios: the UI for the iOS application, written in Swift.

Instructions to build the iOS and the Android apps are provided here.
