+# Code Quality Guide
+
+Standards and practices for maintaining high code quality in the Impersonator project.
+
+## Code Standards
+
+### TypeScript
+
+- **Strict Mode:** Enabled
+- **Type Safety:** All functions typed
+- **No `any`:** Avoid `any` type
+- **Interfaces:** Use interfaces for object shapes
+- **Type Guards:** Use type guards when needed
+
+### Code Style
+
+- **Formatting:** Prettier
+- **Indentation:** 2 spaces
+- **Semicolons:** Required
+- **Quotes:** Single quotes
+- **Trailing Commas:** Yes
+
+### Naming Conventions
+
+- **Components:** PascalCase (`WalletManager`)
+- **Functions:** camelCase (`validateAddress`)
+- **Constants:** UPPER_SNAKE_CASE (`MAX_GAS_LIMIT`)
+- **Types/Interfaces:** PascalCase (`SmartWalletConfig`)
+- **Files:** Match export name
+
+## Linting
+
+### ESLint Configuration
+
+The project uses ESLint with Next.js configuration.
+
+**Run Linter:**
+```bash
+pnpm lint
+```
+
+**Fix Issues:**
+```bash
+pnpm lint --fix
+```
+
+### Common Rules
+
+- No unused variables
+- No console.log in production
+- Consistent return statements
+- Proper error handling
+- No magic numbers
+
+## Formatting
+
+### Prettier Configuration
+
+Automatic formatting on save (VS Code).
+
+**Manual Format:**
+```bash
+npx prettier --write .
+```
+
+### Formatting Rules
+
+- 2 space indentation
+- Single quotes
+- Semicolons required
+- Trailing commas
+- 80 character line length (soft)

+
+## Best Practices
+
+### 1. Function Design
+
+```typescript
+// ✅ Good: Single responsibility, typed, documented
+/**
+ * Validates Ethereum address
+ * @param address - Address to validate
+ * @returns Validation result with checksummed address
+ */
+function validateAddress(address: string): ValidationResult {
+  // Implementation
+}
+
+// ❌ Bad: Multiple responsibilities, no types
+function process(address) {
+  // Does too much
+}
+```
+
+### 2. Error Handling
+
+```typescript
+// ✅ Good: Proper error handling
+try {
+  const result = await operation();
+  return result;
+} catch (error: any) {
+  monitoring.error("Operation failed", error);
+  throw new Error("Operation failed");
+}
+
+// ❌ Bad: Swallowed errors
+try {
+  await operation();
+} catch (error) {
+  // Silent failure
+}
+```
+
+### 3. Constants
+
+```typescript
+// ✅ Good: Constants extracted
+import { SECURITY } from "@/utils/constants";
+const maxGas = SECURITY.MAX_GAS_LIMIT;
+
+// ❌ Bad: Magic numbers
+const maxGas = 10000000;
+```
+
+### 4. Type Safety
+
+```typescript
+// ✅ Good: Proper typing
+interface Config {
+  address: string;
+  networkId: number;
+}
+
+function createWallet(config: Config): Promise<Wallet> {
+  // Implementation
+}
+
+// ❌ Bad: No types
+function createWallet(config) {
+  // Implementation
+}
+```
+
+### 5. Component Structure
+
+```typescript
+// ✅ Good: Clean component
+export default function WalletManager() {
+  const { activeWallet } = useSmartWallet();
+  const [loading, setLoading] = useState(false);
+
+  const handleAction = useCallback(async () => {
+    // Implementation
+  }, [dependencies]);
+
+  return (
+    <Box>
+      {/* JSX */}
+    </Box>
+  );
+}
+
+// ❌ Bad: Messy component
+export default function WalletManager() {
+  // Too much logic
+  // Unclear structure
+  // No memoization
+}
+```
+
+## Code Metrics
+
+### Complexity
+
+- **Cyclomatic Complexity:** < 10 per function
+- **Function Length:** < 50 lines
+- **File Length:** < 500 lines
+- **Component Props:** < 10 props
+
+### Maintainability
+
+- **Code Duplication:** < 5%
+- **Test Coverage:** > 80%
+- **Documentation:** All public APIs
+- **Comments:** Explain "why" not "what"
+
+## Refactoring Guidelines
+
+### When to Refactor
+
+- Code duplication detected
+- Function too long/complex
+- Poor naming
+- Hard to test
+- Performance issues
+
+### Refactoring Steps
+
+1. Write tests first
+2. Make small changes
+3. Run tests frequently
+4. Keep functionality same
+5. Improve incrementally
+
+## Documentation Standards
+
+### JSDoc Comments
+
+```typescript
+/**
+ * Validates Ethereum address with checksum verification
+ * @param address - The Ethereum address to validate
+ * @returns Validation result with checksummed address if valid
+ * @example
+ * const result = validateAddress("0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb");
+ * if (result.valid) {
+ *   const checksummed = result.checksummed!;
+ * }
+ */
+export function validateAddress(address: string): ValidationResult {
+  // Implementation
+}
+```
+
+### README Updates
+
+Update README when:
+- Adding new features
+- Changing setup process
+- Updating dependencies
+- Breaking changes
+
+## Performance Considerations
+
+### Optimization
+
+- Use `useMemo` for expensive calculations
+- Use `useCallback` for callbacks
+- Lazy load heavy components
+- Code split by route
+- Optimize images
+
+### Monitoring
+
+- Track performance metrics
+- Monitor bundle size
+- Check render times
+- Profile slow operations
+
+## Dependency Management
+
+### Adding Dependencies
+
+1. Check if already exists
+2. Verify security
+3. Check bundle size
+4. Review documentation
+5. Test thoroughly
+
+### Updating Dependencies
+
+```bash
+# Check for updates
+pnpm outdated
+
+# Update dependencies
+pnpm update
+
+# Security audit
+pnpm audit
+```
+
+## CI/CD Quality Gates
+
+### Automated Checks
+
+- Linting passes
+- Tests pass
+- Coverage maintained
+- Build succeeds
+- Security audit clean
+
+### Manual Review
+
+- Code review required
+- Architecture review for large changes
+- Security review for sensitive changes
+
+## Tools
+
+### VS Code Extensions
+
+- ESLint
+- Prettier
+- TypeScript
+- Jest
+- GitLens
+
+### Pre-commit Hooks
+
+Consider adding:
+- Linting
+- Formatting
+- Tests
+- Type checking
