CLI tool to set up CDP (Coinbase Developer Platform) documentation and integration in your project

# 🔧 CDP Wallet Setup Guide

Follow these steps to configure your Coinbase Developer Platform (CDP) wallet integration.

## Step 1: Get CDP API Credentials

1. **Visit the CDP Portal**: Go to [https://portal.cdp.coinbase.com/](https://portal.cdp.coinbase.com/)

2. **Sign in** with your Coinbase account or create a new one

3. **Create API Keys**:
   - Navigate to the "API Keys" section
   - Click "Create API Key"
   - Give your key a descriptive name (e.g., "My Wallet App")
   - Save both the **API Key ID** and **API Key Secret** - you'll need these later

4. **Generate Wallet Secret**:
   - This is used for signing transactions
   - Generate a secure random string or use the CDP portal's generator
   - Keep this secret safe - it's like your master password

## Step 2: Configure Environment Variables

1. **Create Environment File**:
   ```bash
   # In your project root, create .env.local
   touch .env.local
   ```

2. **Add Your Credentials**:
   Open `.env.local` and add your CDP credentials:
   ```bash
   CDP_API_KEY_ID=your_actual_key_id_here
   CDP_API_KEY_SECRET=your_actual_key_secret_here
   CDP_WALLET_SECRET=your_actual_wallet_secret_here
   ```

   **Replace the placeholder values** with your actual credentials from Step 1.

3. **Verify Security**:
   - Confirm `.env.local` is in your `.gitignore` file
   - Never commit this file to version control
   - Never share these credentials publicly

## Step 3: Test the Integration

1. **Start the Development Server**:
   ```bash
   npm run dev
   ```

2. **Open Your Browser**:
   - Navigate to [http://localhost:3000](http://localhost:3000)
   - You should see the CDP Wallet Dashboard

3. **Create Your First Account**:
   - Enter a name for your account (e.g., "My First Wallet")
   - Click "Create Account"
   - You should see your new account appear in the list

4. **Request Test Funds**:
   - Select your account
   - Click "Request Test ETH"
   - Wait a few seconds for the transaction to complete
   - Your balance should update to show testnet ETH

5. **Send a Test Transaction**:
   - Enter a recipient address (you can use your own account address)
   - Enter a small amount (e.g., 0.001)
   - Click "Send Transaction"
   - View the transaction on the Base Sepolia explorer

## 🎉 Success Criteria

Your integration is working correctly if:

- ✅ Dashboard loads without errors
- ✅ You can create new accounts
- ✅ Faucet requests work and fund your accounts
- ✅ You can send transactions successfully
- ✅ Transaction links open on BaseScan explorer

## 🔒 Security Best Practices

- **Never commit** `.env.local` to version control
- **Use testnet only** for development and testing
- **Keep your API keys secure** - treat them like passwords
- **Use different keys** for development vs production
- **Rotate keys regularly** if building production apps

## 🚨 Troubleshooting

### Environment Variable Issues
- Ensure `.env.local` is in your project root directory
- Restart your development server after changing environment variables
- Double-check there are no extra spaces in your credential values

### API Connection Issues
- Verify your API credentials are correct
- Check your internet connection
- Ensure you're using the correct CDP portal account

### Transaction Failures
- Make sure your account has sufficient testnet ETH
- Verify recipient addresses are valid Ethereum addresses
- Check that you're using reasonable gas amounts

### Build Errors
- Run `npm run build` to check for TypeScript errors
- Ensure all dependencies are installed: `npm install`
- Clear your `.next` cache: `rm -rf .next` then restart

## 📚 Next Steps

Once your basic integration is working:

1. **Explore Advanced Features**:
   - Smart accounts with gas sponsorship
   - Batch transactions
   - Multi-network support (Ethereum, Solana)

2. **Build Custom Features**:
   - Custom transaction types
   - Transaction history
   - Address book functionality
   - Portfolio tracking

3. **Prepare for Production**:
   - Set up mainnet credentials
   - Implement proper error handling
   - Add comprehensive testing
   - Security audit your implementation
