Technical Implementation

Header Component (`components/Header.tsx`)

// Enhanced coin button with modal
<Dialog open={balanceModalOpen} onOpenChange={setBalanceModalOpen}>
  <DialogTrigger asChild>
    <Button
      variant="ghost"
      className="hover:scale-105 transition-all duration-200"
      onClick={refreshBalances}
      disabled={isRefreshingBalance}
    >
      <Coins className="text-green-500" />
      <span>{balance.toFixed(2)}</span>
      {loggedIn && <div className="animate-pulse bg-green-500 rounded-full" />}
    </Button>
  </DialogTrigger>
  <DialogContent>
    {/* Balance details modal content */}
  </DialogContent>
</Dialog>

Web3Auth Provider (`components/Web3AuthProvider.tsx`)

// Enhanced with real-time balance updates
useEffect(() => {
  if (!loggedIn) return;
  
  const updateBalance = async () => {
    const balance = await getSolanaBalance();
    setSolanaBalance(balance);
  };
  
  const interval = setInterval(updateBalance, 30000);
  return () => clearInterval(interval);
}, [loggedIn]);

Solana Wallet Component (`components/SolanaWallet.tsx`)

// Dedicated wallet component with full functionality
export default function SolanaWallet({ showTransactions = true }) {
  // Wallet state management
  // Transaction history
  // Balance display
  // Address management
}

Usage Instructions

1. Connecting Wallet

Click the "Login" button in the header

Database Integration

Balance Tracking

ScrapAI Points: Stored in database, calculated from transactions
Solana Balance: Fetched from Solana blockchain
Transaction History: Stored in SolanaTransactions table

Key Database Functions

// Get user balance from database
getUserBalance(userId: number): Promise<number>

// Get Solana transactions
getSolanaTransactions(userId: number, limit: number): Promise<any[]>

// Create Solana transaction record
createSolanaTransaction(userId, hash, type, amount, usdValue, description)

Real-time Updates

Event System

Balance Updates: Custom events for real-time balance changes
Transaction Updates: Automatic transaction monitoring
Connection Status: Real-time wallet connection monitoring

Update Intervals

Automatic: Every 30 seconds when logged in
Manual: On button click or modal open
Event-driven: On transaction completion

Error Handling

Connection Errors

Web3Auth Errors: Graceful fallback to demo mode
Network Errors: Retry mechanisms with exponential backoff
User Feedback: Clear error messages and status indicators

Fallback Mechanisms

Demo Mode: Uses demo address and balance when connection fails
Local Storage: Persists user session for offline functionality
Timeout Handling: 5-second timeout for initialization

Testing
