full UTXO set. This reduces storage requirements from tens of gigabytes to just a few megabytes, making it practical to run a full validating node on mobile devices.\n\n## Installation\n\n### Requirements\n- Android 10 (API 29) or higher\n- ARM64 device (arm64-v8a architecture)\n- Internet connection\n\n### Releases\nDownload the latest APK from [GitHub Releases](https://github.com/jvsena42/mandacaru/releases).\n\n### From Source\n1. Clone the repository:\n```bash\ngit clone https://github.com/jvsena42/mandacaru.git\ncd mandacaru\n```\n\n2. Build the project:\n```bash\n./gradlew assembleDebug\n```\n\n3. Install on your device:\n```bash\n./gradlew installDebug\n```\n\n## Usage\n\n### Getting Started\n1. Launch the app and enable notifications when prompted\n2. Add a wallet descriptor to track your addresses (in Settings \u003e Descriptors)\n3. Copy the Electrum server address (in Settings), then configure your wallet to use it as an Electrum server\n\n### Node Info Screen\nMonitor your node's status:\n- **Sync Progress**: Current blockchain synchronization percentage\n- **Network Info**: Connected network, peer count, and difficulty\n- **Peers** (expandable): View connected peers, connect to new nodes, disconnect, or ping\n- **Diagnostics** (expandable): Node uptime and memory usage\n\n### Transaction Screen\nSearch and broadcast transactions:\n- Enter a transaction ID (txid) to look up transaction details\n- Broadcast a raw transaction to the network\n- View complete transaction details and confirmations\n\n### Blockchain Screen\nExplore the blockchain:\n- **Block Search**: Look up blocks by height or hash\n- **Chain Status**: View block count, best block hash, and validated blocks\n- **Block Headers**: View detailed block header information\n\n### Settings Screen\nConfigure your node:\n- **Electrum Address**: Copy the local Electrum server address to pair with your wallet\n- **Descriptors**: Add or list wallet descriptors to track your addresses\n- **Network**: Switch between Bitcoin networks (requires app restart)\n- **Node**: Connect directly to specific Bitcoin nodes\n- **About**: App version and project information\n- **Donate**: Support the project via Lightning\n\n## Architecture\n\nBuilt with modern Android development practices:\n- **Kotlin**: 100% Kotlin codebase\n- **Jetpack Compose**: Declarative UI framework\n- **Material Design 3**: Modern, adaptive design system\n- **HorizontalPager + BottomNavigationBar**: Swipeable screen navigation\n- **MVVM Architecture**: Clean separation of concerns\n- **Coroutines \u0026 Flow**: Async operations and reactive streams\n- **DataStore**: Persistent preferences\n- **Koin**: Lightweight dependency injection\n- **OkHttp**: Network communication\n- **JSON-RPC**: Bitcoin Core compatible RPC interface\n\n## Related Projects\n\n- [Floresta Wallet](https://github.com/jvsena42/floresta_app) - A wallet client running Floresta\n- [Floresta Core](https://github.com/vinteumorg/Floresta) - The underlying Floresta implementation\n\n## Support the Project\n\nIf you find this project useful, consider supporting development:\n\n**Lightning**: `jvsena42@blink.sv`\n\n## License\n\nThis project is open source.
