# 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
|
|
|

|
|
- 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
|
|
|
|
