Phoenix Logo

Phoenix is a Bitcoin wallet developed by ACINQ, that allows you to send and receive bitcoins 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. Your key, your bitcoins. But make sure you backup your key so you do not lose your money. Do not share your key with anyone.

Phoenix is available for Android and iOS:

Build and test Phoenix

Phoenix is currently separated into two codebases:

  • the legacy Android app, found in the phoenix-legacy folder, using our own Scala eclair-core library for Lightning. Instructions to build this app are provided here
  • the iOS app found in the phoenix-ios folder, using our own Kotlin MultiPlatform lightning-kmp library for Lightning. Instructions to build this app are provided here

The phoenix-android folder contains the new Android app that shares code with the iOS app and use lightning-kmp. This app is not ready yet. It will eventually replace the legacy Android app.


We use GitHub for bug tracking. Search the existing issues for your bug and create a new one if needed.

You can also contribute to the project by submitting pull requests to improve the codebase or bring new features. Pull requests will be reviewed by members of the ACINQ team.

To contribute to Lightning in general, take a look at the Eclair repository for routing nodes, or the lightning-kmp repository for mobile nodes.
