🚀 Add Universal Stellar Wallet Connect Support

📋 Summary

Implements comprehensive wallet connection functionality for CodeCodely, enabling users to connect their Stellar wallets (Freighter, Albedo, and Lobstr) to the platform. This provides the foundation for wallet-based authentication and future blockchain features.

✨ Features Added

Wallet Support

  • Freighter - Browser extension wallet with auto-detection and 5-second wait time
  • Albedo - Web-based wallet with instant authentication popup
  • Lobstr - Architecture ready (displays "coming soon" message)

UI Components

  • Connect Wallet Button - Gradient-styled button (purple-to-blue) with wallet icon
  • Wallet Selection Modal - Clean dialog with 3 wallet options
  • Connected State - Displays shortened public key (GXXX...XXXX) with disconnect functionality
  • Error Handling - User-friendly error messages displayed in modal

State Management

  • Global wallet context using React Context API
  • Tracks: connected, publicKey, walletName, connecting, error
  • Error clearing on modal reopen
  • Clean disconnect functionality

🏗️ Technical Implementation

Architecture

components/
├── WalletConnect.tsx          # Main wallet logic + UI components
├── ClientWalletProvider.tsx   # Client wrapper for server components
└── ui/
    └── dialog.tsx             # Modal component (Radix UI)

Key Functions

  • connect(walletType) - Handles wallet-specific connection logic
  • disconnect() - Clears wallet state
  • clearError() - Resets error state
  • Auto-detection with retry logic for browser extensions

Dependencies Added

  • @albedo-link/intent - Albedo wallet integration

🎨 Design

  • Matches existing CodeCodely brand (purple/blue gradient)
  • Responsive button with loading states
  • Wallet icon from lucide-react
  • Clean modal with wallet descriptions
  • Error display with red theme

🔒 Security

  • No private keys stored or transmitted
  • Only public key retrieval
  • User must approve each connection
  • Wallet-specific authentication flows respected

✅ Acceptance Criteria Met

  • "Connect Wallet" button visible in navbar
  • Freighter wallet support with extension detection
  • Albedo wallet support (fully functional)
  • Lobstr wallet architecture ready
  • Public key displayed in shortened format
  • Disconnect functionality working
  • Clean error handling with user-friendly messages
  • Extensible architecture for future wallets
  • No mock wallets (production-ready)
  • TypeScript type safety
  • No build or runtime errors

🧪 Testing

Tested with:

  • ✅ Albedo connection (web-based, works immediately)
  • ✅ Freighter detection and error handling
  • ✅ Modal open/close behavior
  • ✅ Error clearing on retry
  • ✅ Disconnect functionality
  • ✅ Responsive design
  • ✅ TypeScript compilation
  • ✅ Build process

📝 Usage

// Wallet is available globally via context
import { useWallet } from '@/components/WalletConnect';

function MyComponent() {
  const { connected, publicKey, connect, disconnect } = useWallet();
  
  if (connected) {
    return <div>Connected: {publicKey}</div>;
  }
  
  return <button onClick={() => connect('albedo')}>Connect</button>;
}

🚀 Future Enhancements

  • Complete Lobstr/WalletConnect integration (requires project ID)
  • Persist wallet connection across page refreshes
  • Add network selection (testnet/mainnet toggle)
  • Transaction signing functionality
  • Multiple account support
  • Wallet-specific icons instead of emojis

📸 Screenshots

  • Connect Wallet button in navbar with gradient styling
  • Modal showing 3 wallet options (Freighter, Albedo, Lobstr)
