🔧 Technical Debt

  • ⚠️ Using KivyMD 1.2.0 (deprecated but stable)
  • ⚠️ Modal selectors may still use MDDropdownMenu (needs audit)
  • ⚠️ Some screens may benefit from additional polish

🏗️ Architecture Overview

Core Components

  1. app.py - Main application class with screen management
  2. calorieapptestnet.kv - 4000+ line KV file with all UI layouts
  3. 25+ Screen Classes - Modular screen implementations
  4. Utility Modules - XRPL client, navigation, mnemonic, token config

Key Systems

  • Conditional Navigation: Intelligent drawer creation per screen
  • XRPL Multi-Server Failover: 4+ testnet servers with automatic switching
  • Mnemonic Manager: BIP39 implementation for wallet recovery
  • Token Config System: Centralized custom token management
  • Robust Transactions: Retry logic and error handling

Data Flow

User Input → Screen → Utility/Manager → XRPL Client → XRPL Testnet

🧪 Testing Status

✅ Tested Features

  • Wallet creation with mnemonic generation
  • Wallet import via mnemonic
  • Wallet import via keypair
  • XRP sending and receiving
  • Multi-wallet switching
  • Transaction history display
  • Trustline creation
  • Navigation flow across all screens
  • XRPL server failover

🚀 Next Steps

Immediate Priorities

  1. APK Build Testing

    • Build APK with buildozer
    • Install on Android device
    • Test all core features on device
    • Verify performance and responsiveness

  2. UI Polish

    • Audit any remaining MDDropdownMenu usage
    • Ensure consistent spacing/padding
    • Test on various screen sizes
    • Dark mode considerations (if applicable)

  3. Documentation

    • Create user manual/guide
    • Document token addition process
    • Add troubleshooting section
    • Create developer setup guide

Future Enhancements

  • Biometric authentication support
  • QR code scanning for addresses
  • Address book functionality
  • Transaction export (CSV/PDF)
  • Multi-language support
  • Price tracking integration
  • Enhanced NFT gallery
  • Token swap functionality
  • Backup to cloud storage

📋 Known Issues

None Currently Reported

All major bugs from previous versions have been resolved.

Potential Concerns

  • KivyMD 1.2.0 deprecation warnings (addressed by removing problematic components)
  • Large transaction histories may impact load times (needs optimization if issue arises)
  • Network connectivity in poor conditions (failover helps but not perfect)

🔐 Security Considerations

✅ Implemented

  • Encrypted wallet storage
  • Password-protected access
  • Secure mnemonic generation (BIP39)
  • No private keys logged or displayed unnecessarily
  • HTTPS connections to XRPL servers

📝 Recommendations for Production
