+# Quick Reference Guide
+
+Quick reference for common tasks and patterns in the Impersonator Smart Wallet system.
+
+## Common Code Patterns
+
+### Validate Address
+
+```typescript
+import { validateAddress } from "@/utils/security";
+
+const validation = validateAddress(address);
+if (!validation.valid) {
+  throw new Error(validation.error);
+}
+const checksummed = validation.checksummed!;
+```
+
+### Create Transaction
+
+```typescript
+import { useTransaction } from "@/contexts/TransactionContext";
+
+const { createTransaction } = useTransaction();
+const tx = await createTransaction({
+  from: walletAddress,
+  to: recipientAddress,
+  value: ethers.utils.parseEther("1.0").toHexString(),
+  data: "0x",
+  method: TransactionExecutionMethod.DIRECT_ONCHAIN,
+});
+```
+
+### Use Secure Storage
+
+```typescript
+import { SecureStorage } from "@/utils/encryption";
+
+const storage = new SecureStorage();
+await storage.setItem("key", JSON.stringify(data));
+const data = await storage.getItem("key");
+```
+
+### Rate Limiting
+
+```typescript
+import { RateLimiter } from "@/utils/security";
+
+const limiter = new RateLimiter();
+if (!limiter.checkLimit(userAddress)) {
+  throw new Error("Rate limit exceeded");
+}
+```
+
+### Monitor Events
+
+```typescript
+import { monitoring } from "@/utils/monitoring";
+
+monitoring.info("Event occurred", { context });
+monitoring.error("Error occurred", error, { context });
+```
+

+## Common Tasks
+
+### Add New Network
+1. Add to `NETWORKS.SUPPORTED_NETWORK_IDS` in `utils/constants.ts`
+2. Update network list component
+3. Test connection
+
+### Add New Validation
+1. Add function to `utils/security.ts`
+2. Add JSDoc comment
+3. Write tests
+4. Use in components
+
+### Add New Component
+1. Create in appropriate `components/` subdirectory
+2. Export component
+3. Add to parent
+4. Write tests
+
+## Testing Commands
+
+```bash
+# Run all tests
+pnpm test
+
+# Run specific test
+pnpm test __tests__/security.test.ts
+
+# Watch mode
+pnpm test:watch
+
+# Coverage
+pnpm test:coverage
+```
