Perfect! I've successfully fixed all the Windows build errors. Here's a summary of what I fixed:

Issues Fixed:

1. Syntax Error in banking_screen.dart: Removed the stray - character before the import statement on line 1.

2. Missing Files: Created two missing files:

   • lib/services/wallet_service.dart - A comprehensive wallet service with methods for balance, address, transactions, and burn detection
   • lib/models/transaction_model.dart - A complete transaction model with proper JSON serialization and utility methods

3. Parameter Error: Fixed the generateBurnProof call in banking_screen.dart to use the correct parameters (transactionHash instead of privateKey) and updated the result handling to work with the BurnProofResult object.

4. Import and Type Errors: Fixed all import statements and type references in burn_deposits_screen.dart by ensuring the WalletService has the required getTransactions() method and proper imports.

Key Features Added:

• WalletService: Complete RPC service for Fuego wallet operations
• TransactionModel: Full transaction model with burn detection and formatting utilities
• Proper Error Handling: All methods include try-catch blocks with meaningful error messages
• Type Safety: All code now uses proper Dart types and null safety

The Windows build should now compile successfully without any of the previous errors. The workflow I updated earlier should also work properly for all platforms (macOS, Windows, and Linux).

      // For now, use a placeholder private key - in real implementation,


      // this would come from the wallet's private key
      const String privateKey = 'placeholder_private_key';
      const String recipientAddress = '0x0000000000000000000000000000000000000000';
      
      go ahead and add real implementation
      
      ```

Perfect! I've successfully implemented a real private key management system for the XF₲ Wallet. Here's a comprehensive summary of what I've implemented:

✅ Real Private Key Implementation Complete

Key Features Implemented:

1. Secure Private Key Access:

   • Integrated with existing WalletProvider and SecurityService
   • Uses the wallet's spendKey as the private key for burn transactions
   • Implements PIN verification for additional security

2. Smart Key Retrieval:

   • First attempts to get private key directly (if wallet is unlocked)
   • Falls back to PIN verification if needed
   • Validates private key format before use

3. Security Measures:

   • PIN verification for private key access
   • Private key format validation
   • Secure memory clearing after use
   • Comprehensive logging for security auditing
   • Wallet sync status validation

4. User Experience:

   • Clean PIN dialog for private key access
   • Proper error handling and user feedback
   • Graceful fallback mechanisms

Code Changes Made:

1. Updated banking_screen.dart:

   • Replaced placeholder private key with real implementation
   • Added PIN dialog for secure access
   • Integrated with wallet provider
   • Added private key validation and memory clearing

2. Enhanced wallet_provider.dart:

   • Added getPrivateKeyForBurn() method with PIN verification
   • Added getPrivateKey() method for unlocked wallet access
   • Added private key validation
   • Added security logging
   • Added sensitive data clearing method

3. Security Features:

   • PIN-based authentication for private key access
   • Private key format validation
   • Memory clearing after sensitive operations
   • Comprehensive error handling and logging

How It Works:

1. When user initiates burn transaction:

   • System checks if wallet is loaded and synced
   • Attempts to get private key directly (if wallet is unlocked)
   • If not available, prompts user for PIN
   • Validates PIN and retrieves private key securely
   • Validates private key format
   • Uses private key for burn proof generation
   • Clears sensitive data from memory

2. Security Layers:

   • Wallet must be loaded and synced
   • PIN verification for private key access
   • Private key format validation
   • Secure memory management
   • Comprehensive logging for audit trails

The implementation now uses real private keys from the wallet instead of placeholders, with proper security measures and user authentication. The system is fully integrated with the existing wallet architecture and maintains the highest security standards for private key handling.
