About

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.

Runtime requirements

• Android version 4.4 (API level 19) or higher
• Google Play services

Structure

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.

Build

For instructions on how to build Muun Wallet please refer to BUILD.md.

Auditing

• 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.
