[boldbitcoin]

Summary

This PR includes all features and fixes for version 2.1.7, with a focus on improving transaction display, Docker build infrastructure, QR code enhancements, and various bug fixes.

🚀 New Features

Transaction Display Improvements

• Multiple Address Display in Transactions: Transaction details now show all recipient addresses for sent transactions and all sender addresses for received transactions
  • Sent transactions with multiple outputs (e.g., PSBT transactions) display all recipient addresses with individual amounts
  • Received transactions with multiple inputs display all sender addresses with the received output amount
  • Each address shows its BTC amount and fiat equivalent
  • Transaction list shows count indicator for multiple recipients: "To: address... (+2 more)"

Docker Build System

• Complete Docker-based build infrastructure for Android APK compilation with cross-platform support
• New docker/scripts/ directory with comprehensive build automation
• Cross-platform support (macOS and Linux) with QEMU emulation for macOS/ARM
• BuildKit optimizations with layer caching, cache mounts, and inline cache
• Comprehensive documentation in docker/README.md

Enhanced QR Code for Send Bitcoin

• QR codes now include address type, derivation path, and network
• Prevents session timeouts when scanning QR codes between devices
• Enables second device to use exact same source address and network as first device
• Backward compatible with older QR code formats

From Address Display

• Transaction details now show the source (from) address in pairing screens
• Helps users verify both devices are using the same source address
• Shown in both Nostr and Local WiFi pairing screens

Watch-Only Wallet Export

• Streamlined to output descriptors only (removed xpub/tpub export)
• Focus on output descriptors (Legacy, SegWit Native, SegWit Compatible) for better compatibility
• Added Taproot support warning in export UI

🔧 Changes

• Docker Build System: Moved Docker scripts to organized docker/scripts/ directory
• Android Build Configuration: Enhanced build system with Docker-specific Gradle settings and improved ProGuard rules

🐛 Bug Fixes

• Nostr Transport Panic Recovery: Enhanced panic recovery in co-signing operations with better error handling
• Legacy Wallet Migration Modal: New modal appears for users with legacy wallets, advising migration to new wallet setup
• Network Reset on Wallet Import: Network always resets to mainnet when importing a keyshare to ensure clean state
• Address Flickering Issue: Fixed address changing/flickering after lock/unlock by making UserContext the single source of truth
• Session Timeout Fix for QR Code Scanning: Fixed session timeouts when scanning send Bitcoin QR codes from second device
• TransactionList Loading State: Fixed infinite "Loading..." state and network errors when restoring wallet for the first time

📝 Files Changed

• CHANGELOG.md - Updated with all v2.1.7 features
• components/TransactionDetailsModal.tsx - Multiple address display with amounts
• components/TransactionList.tsx - Multiple recipient address collection and display
• components/Styles.tsx - Style improvements
• Docker build scripts and configuration files

✅ Testing

• Tested with PSBT transactions having multiple outputs
• Tested with received transactions having multiple inputs
• Verified amount calculations are correct
• Verified UI displays properly formatted
• Docker build system tested on macOS and Linux
• QR code scanning tested with enhanced format

📋 Related

• Fixes issue where transactions with multiple outputs only showed the first recipient address
• Improves Docker build workflow and cross-platform compatibility
• Enhances QR code reliability for multi-device transactions
