+
+## 📝 Code Examples
+
+### Using Wallet Info in Other Components
+```tsx
+import { useAccount, useBalance } from 'wagmi';
+
+function MyComponent() {
+  const { address, isConnected } = useAccount();
+  const { data: balance } = useBalance({ address });
+
+  return (
+    <div>
+      {isConnected && (
+        <p>Balance: {balance?.formatted} {balance?.symbol}</p>
+      )}
+    </div>
+  );
+}
+```
+
+### Network Switching
+```tsx
+import { useSwitchChain } from 'wagmi';
+import { sepolia } from 'wagmi/chains';
+
+function SwitchNetwork() {
+  const { switchChain } = useSwitchChain();
+
+  const handleSwitch = () => {
+    switchChain({ chainId: sepolia.id });
+  };
+
+  return <button onClick={handleSwitch}>Switch to Sepolia</button>;
+}
+```
+
+## 🐛 Known Issues
+
+1. **Voting History**: Currently uses mock data - needs integration with blockchain indexer or backend API
+2. **ENS Resolution**: May be slow on some networks - consider caching
+3. **Balance Updates**: Real-time updates depend on RPC endpoint reliability
+
+## 🤝 Contributing
+
+When extending this feature:
+1. Follow the existing component structure
+2. Use wagmi hooks for blockchain interactions
+3. Maintain responsive design patterns
+4. Add loading states for async operations
+5. Include error handling with user-friendly messages
+
+## 📄 License
+
+This feature is part of the Agora-Blockchain project and follows the same license.
