This is the source code repository for muun's android wallet. Muun is a non-custodial 2-of-2 multisig wallet with a special focus on security and ease of use.
- Android version 4.4 (API level 19) or higher
- Google Play services
The app follows the clean architecture pattern, and has three layers:
- Data: handles the data backends, such as the database, the operating system, or the network.
- Domain: contains the models and business logic (use cases in clean architecture lingo).
- Presentation: contains the UI code.
There's also a pure java common module with code shared all over.
For instructions on how to build Muun Wallet please refer to BUILD.md.
- Most of the key handling and transaction crafting operations happen in the common module.
- All the keystore and data handling happens in the data layer.
- All the business logic that decides when to sign what happens in the domain layer.
- The presentation layer only depends on the domain layer, it never references data directly.
We are currently not accepting contributions in PR form. We are a small team and our development flow cannot manage external contributions yet. Sadly, this includes contributions for support for other languages. Having said that, we love to get feedback and suggestions for improvements. We have included some external contributions in the past, just not in the "accept and merge" a PR traditional way.
