# 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 });
```
