+# Mobile Wallet Signature Verification Fixes
+
+## Issue Description
+The mobile wallet adapter was experiencing "signature verification failed, missing signature for public key" errors when trying to pay DINO coins. This is a common issue with mobile Solana wallets due to differences in how they handle transaction signing and verification.
+
+## Root Causes Identified
+
+1. **Missing Transaction Fields**: Mobile wallets require specific transaction fields like `lastValidBlockHeight`
+2. **Incorrect Commitment Levels**: Mobile wallets work better with 'confirmed' commitment vs 'finalized'
+3. **Missing Preflight Checks**: Mobile wallets benefit from transaction simulation before sending
+4. **Insufficient Error Handling**: Generic error messages didn't help debug mobile-specific issues
+5. **Transaction Validation**: Missing validation for required transaction properties
+
+## Solutions Implemented
+
+### 1. Enhanced Transaction Construction
+- Added `lastValidBlockHeight` to transactions
+- Set proper commitment levels for mobile devices
+- Added transaction validation before sending
+
+### 2. Mobile-Optimized Transaction Sending
+- Created `sendTransactionWithMobileOptimization` utility function
+- Added retry logic with exponential backoff
+- Implemented proper error handling for mobile wallets
+
+### 3. Enhanced Error Handling
+- Mobile-specific error messages
+- Better debugging information for mobile devices
+- Specific handling for signature verification failures
+
+### 4. Preflight Transaction Checks
+- Added transaction simulation before sending
+- Mobile-specific validation rules
+- Graceful fallback for preflight failures
+
+### 5. Additional Wallet Adapters
+- Added support for more mobile-friendly wallets
+- Better mobile wallet detection
+- Improved wallet connection handling
+
+## Code Changes Made
+
+### `app/page.tsx`
+- Updated transaction construction with mobile-optimized parameters
+- Added mobile-specific validation and error handling
+- Integrated mobile wallet utility functions
+
+### `app/components/WalletProvider.tsx`
+- Added more wallet adapters for better mobile support
+- Enhanced error handling for mobile wallets
+- Added mobile-specific wallet configuration
+
+### `app/utils/mobileWalletUtils.ts` (New File)
+- Mobile-optimized transaction sending function
+- Mobile device detection utilities
+- Transaction validation for mobile wallets
+
+## Testing Recommendations
+
+1. **Test on Multiple Mobile Devices**
+   - iOS Safari with Phantom wallet
+   - Android Chrome with Solflare wallet
+   - Different screen sizes and orientations
+
+2. **Test Different Network Conditions**
+   - Slow network connections
+   - Intermittent connectivity
+   - High latency scenarios
+
+3. **Test Wallet States**
+   - Fresh wallet connections
+   - Reconnected wallets
+   - Wallets with different token balances
+
+## Common Mobile Wallet Issues and Solutions
+
+### Issue: "Signature verification failed"
+**Solution**: Ensure transaction has all required fields and proper commitment levels
+
+### Issue: "Missing signature for public key"
+**Solution**: Validate transaction before sending and use mobile-optimized sending
+
+### Issue: "Transaction simulation failed"
+**Solution**: Check wallet connection and ensure proper transaction construction
+
+### Issue: "User rejected transaction"
+**Solution**: Provide clear error messages and retry options
+
+## Future Improvements
+
+1. **Wallet-Specific Optimizations**
+   - Phantom-specific transaction handling
+   - Solflare-specific optimizations
+   - Hardware wallet support
+
+2. **Better Mobile UX**
+   - Mobile-specific UI components
+   - Touch-friendly interactions
+   - Better mobile error display
+
+3. **Advanced Error Recovery**
+   - Automatic retry mechanisms
+   - Transaction recovery options
+   - Better user guidance
+
+## Monitoring and Debugging
+
+The implementation includes enhanced logging for mobile devices:
+- Device detection information
+- Wallet connection status
+- Transaction validation details
+- Error context for debugging
+
+Check browser console for detailed mobile wallet debugging information when issues occur.
