+
+## Development Patterns
+
+### Context Usage
+
+#### Using SmartWalletContext
+
+```typescript
+import { useSmartWallet } from "@/contexts/SmartWalletContext";
+
+function MyComponent() {
+  const {
+    activeWallet,
+    smartWallets,
+    connectToWallet,
+    createWallet,
+    addOwner,
+    removeOwner,
+    updateThreshold,
+  } = useSmartWallet();
+
+  // Use context values and methods
+}
+```
+
+#### Using TransactionContext
+
+```typescript
+import { useTransaction } from "@/contexts/TransactionContext";
+
+function MyComponent() {
+  const {
+    transactions,
+    pendingTransactions,
+    createTransaction,
+    approveTransaction,
+    executeTransaction,
+    estimateGas,
+  } = useTransaction();
+
+  // Use context values and methods
+}
+```
+
+#### Using SafeInjectContext
+
+```typescript
+import { useSafeInject } from "@/contexts/SafeInjectContext";
+
+function MyComponent() {
+  const {
+    address,
+    appUrl,
+    setAddress,
+    setAppUrl,
+    iframeRef,
+    latestTransaction,
+  } = useSafeInject();
+
+  // Use context values and methods
+}
+```
+
+### Component Patterns
+
+#### Functional Components with Hooks
+
+```typescript
+"use client";
+
+import { useState, useEffect } from "react";
+import { Box, Button } from "@chakra-ui/react";
+
+export default function MyComponent() {
+  const [state, setState] = useState<string>("");
+
+  useEffect(() => {
+    // Side effects
+  }, []);
+
+  return (
+    <Box>
+      <Button onClick={() => setState("new value")}>
+        Click me
+      </Button>
+    </Box>
+  );
+}
+```
+
+#### Form Handling
+
+```typescript
+import { useState } from "react";
+import { useToast } from "@chakra-ui/react";
+import { validateAddress } from "@/utils/security";
+
+function AddressForm() {
+  const [address, setAddress] = useState("");
+  const toast = useToast();
+
+  const handleSubmit = async () => {
+    // Validate input
+    const validation = validateAddress(address);
+    if (!validation.valid) {
+      toast({
+        title: "Invalid Address",
+        description: validation.error,
+        status: "error",
+      });
+      return;
+    }
+
+    // Process valid address
+    const checksummed = validation.checksummed!;
+    // ... rest of logic
+  };
+
+  return (
+    // Form JSX
+  );
+}
+```
+
+### Error Handling
+
+#### Try-Catch Pattern
+
+```typescript
+try {
+  const result = await someAsyncOperation();
+  // Handle success
+} catch (error: any) {
+  console.error("Operation failed:", error);
+  toast({
+    title: "Error",
+    description: error.message || "Operation failed",
+    status: "error",
+  });
+}
+```
+
+#### Error Boundary
+
+```typescript
+import ErrorBoundary from "@/components/ErrorBoundary";
+
+function App() {
+  return (
+    <ErrorBoundary>
+      <YourComponent />
+    </ErrorBoundary>
+  );
+}
+```
+
+### Validation Patterns
+
+#### Address Validation
+
+```typescript
+import { validateAddress } from "@/utils/security";
+
+const validation = validateAddress(address);
+if (!validation.valid) {
+  throw new Error(validation.error);
+}
+const checksummed = validation.checksummed!;
+```
+
+#### Transaction Validation
+
+```typescript
+import { validateTransactionRequest } from "@/utils/security";
+
+const validation = validateTransactionRequest({
+  from: "0x...",
+  to: "0x...",
+  value: "1000000000000000000",
+  data: "0x",
+});
+
+if (!validation.valid) {
+  console.error("Validation errors:", validation.errors);
+}
+```
+
+### Async Operations
+
+#### Using Async/Await
+
+```typescript
+async function fetchData() {
+  try {
+    const data = await someAsyncCall();
+    return data;
+  } catch (error) {
+    console.error("Failed to fetch:", error);
+    throw error;
+  }
+}
+```
+
+#### Promise Handling
+
+```typescript
+someAsyncCall()
+  .then((result) => {
+    // Handle success
+  })
+  .catch((error) => {
+    // Handle error
+  });
+```
+
+### State Management
+
+#### Local State
+
+```typescript
+const [value, setValue] = useState<string>("");
+const [loading, setLoading] = useState<boolean>(false);
+```
+
+#### Context State
+
+```typescript
+// Access context state
+const { activeWallet } = useSmartWallet();
+```
+
+#### Derived State
+
+```typescript
+const pendingCount = transactions.filter(
+  (tx) => tx.status === TransactionStatus.PENDING
+).length;
+```
+
+## Security Best Practices
+
+### Input Validation
+
+Always validate user input:
+
+```typescript
+import { validateAddress, validateTransactionValue } from "@/utils/security";
+
+// Validate address
+const addressValidation = validateAddress(userInput);
+if (!addressValidation.valid) {
+  // Handle invalid input
+}
+
+// Validate transaction value
+const valueValidation = validateTransactionValue(value);
+if (!valueValidation.valid) {
+  // Handle invalid value
+}
+```
+
+### Secure Storage
+
+Use SecureStorage for sensitive data:
+
+```typescript
+import { SecureStorage } from "@/utils/encryption";
+
+const storage = new SecureStorage();
+await storage.setItem("key", JSON.stringify(sensitiveData));
+const data = await storage.getItem("key");
+```
+
+### Rate Limiting
+
+Respect rate limits:
+
+```typescript
+import { RateLimiter } from "@/utils/security";
+
+const limiter = new RateLimiter();
+if (!limiter.checkLimit(userAddress)) {
+  throw new Error("Rate limit exceeded");
+}
+```
+
+## Code Style Guidelines
+
+### TypeScript
+
+- Use strict mode
+- Define types for all functions
+- Use interfaces for object shapes
+- Avoid `any` type
+- Use type guards when needed
+
+### Naming Conventions
+
+- **Components**: PascalCase (`WalletManager`)
+- **Functions**: camelCase (`validateAddress`)
+- **Constants**: UPPER_SNAKE_CASE (`MAX_GAS_LIMIT`)
+- **Types/Interfaces**: PascalCase (`SmartWalletConfig`)
+- **Files**: Match export name
+
+### Code Formatting
+
+- Use Prettier for formatting
+- 2 spaces for indentation
+- Semicolons required
+- Single quotes for strings
+- Trailing commas in objects/arrays
+
+### Comments
+
+- Use JSDoc for public APIs
+- Explain "why" not "what"
+- Keep comments up to date
+- Remove commented-out code
+
+## Testing Patterns
+
+### Unit Tests
+
+```typescript
+import { validateAddress } from "@/utils/security";
+
+describe("validateAddress", () => {
+  it("should validate correct addresses", () => {
+    const result = validateAddress("0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb");
+    expect(result.valid).toBe(true);
+  });
+
+  it("should reject invalid addresses", () => {
+    const result = validateAddress("invalid");
+    expect(result.valid).toBe(false);
+  });
+});
+```
+
+### Component Tests
+
+```typescript
+import { render, screen } from "@testing-library/react";
+import WalletManager from "@/components/SmartWallet/WalletManager";
+
+describe("WalletManager", () => {
+  it("should render wallet list", () => {
+    render(<WalletManager />);
+    expect(screen.getByText("Wallets")).toBeInTheDocument();
+  });
+});
+```
+
+## Debugging
+
+### Console Logging
+
+```typescript
+// Use monitoring service for production
+import { monitoring } from "@/utils/monitoring";
+
+monitoring.debug("Debug message", { context });
+monitoring.info("Info message", { context });
+monitoring.warn("Warning message", { context });
+monitoring.error("Error message", error, { context });
+```
+
+### React DevTools
+
+- Install React DevTools browser extension
+- Inspect component tree
+- View props and state
+- Profile performance
+
+### Browser DevTools
+
+- Use Network tab for API calls
+- Use Console for errors
+- Use Application tab for storage
+- Use Sources for debugging
+
+## Performance Optimization
+
+### Memoization
+
+```typescript
+import { useMemo, useCallback } from "react";
+
+// Memoize expensive calculations
+const expensiveValue = useMemo(() => {
+  return computeExpensiveValue(data);
+}, [data]);
+
+// Memoize callbacks
+const handleClick = useCallback(() => {
+  doSomething();
+}, [dependencies]);
+```
+
+### Lazy Loading
+
+```typescript
+import { lazy, Suspense } from "react";
+
+const HeavyComponent = lazy(() => import("./HeavyComponent"));
+
+function App() {
+  return (
+    <Suspense fallback={<div>Loading...</div>}>
+      <HeavyComponent />
+    </Suspense>
+  );
+}
+```
+
+### Code Splitting
+
+Next.js automatically code-splits by route. For manual splitting:
+
+```typescript
+import dynamic from "next/dynamic";
+
+const DynamicComponent = dynamic(() => import("./Component"), {
+  ssr: false,
+});
+```
+
