+2. Go to **Account & Security** → **API Management**
+3. Click **Create New Key**

+- ✅ **Contract** - Required for futures/perpetual trading
+- ❌ **Withdrawals** - Keep disabled for security
+
+## IP Whitelist (Recommended)
+
+For enhanced security:
+
+1. Click **Edit** on your API key
+2. Add your server's IP address to the whitelist
+3. Save changes
+
+## Save Your Keys
+
+After creation, you'll see:
+- **API Key**: `xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx`
+- **API Secret**: `xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx`
+
+⚠️ **Important**: Save the API Secret immediately - it's only shown once!
+
+## Configure in NOFX
+
+Add your API credentials through the NOFX web interface:
+
+1. Open NOFX dashboard (http://localhost:3000)
+2. Go to **Exchange Configuration**
+3. Enable **Bybit**
+4. Enter your API Key and API Secret
+5. Save configuration
+
+## Troubleshooting
+
+| Error | Solution |

+| `Invalid API key` | Check if API key is correct |
+| `Signature error` | Check if API Secret is correct |
+| `IP not allowed` | Add your IP to whitelist |
+| `Permission denied` | Enable Contract trading permission |
+
+## Security Best Practices
+
+- Never share your API keys
+- Use IP whitelisting
+- Don't enable withdrawal permissions
+- Create separate API keys for different applications
+- Regularly rotate your API keys

+# Lighter Agent Wallet Setup Guide
+
+This guide explains how to create and configure an Agent Wallet for secure trading on Lighter.
+
+## Why Use Agent Wallet?
+
+- ✅ **More Secure**: Never expose your main wallet private key
+- ✅ **Limited Access**: Agent only has trading permissions
+- ✅ **Revocable**: Can be disabled anytime
+- ✅ **Separate Funds**: Keep main holdings safe
+
+## Prerequisites
+
+- A Web3 wallet (MetaMask, WalletConnect, etc.)
+- Access to [Lighter](https://lighter.xyz)
+
+## Step 1: Connect Your Main Wallet
+
+1. Visit [Lighter](https://lighter.xyz)
+2. Click **Connect Wallet**
+3. Choose MetaMask, WalletConnect, or other Web3 wallet
+4. Approve the connection
+
+## Step 2: Create Agent Wallet
+
+1. Navigate to **Settings** or **API** section
+2. Look for **Agent Wallet** or **Trading Wallet** option
+3. Click **Create Agent** or **Generate New Wallet**
+4. Approve the transaction if required
+
+## Step 3: Save Agent Credentials
+
+After creation, save these immediately:
+
+| Field | Description |
+|-------|-------------|
+| **Main Wallet Address** | Your connected wallet address |
+| **Agent Wallet Address** | Generated agent wallet address |
+| **Agent Private Key** | Private key for the agent wallet |
+
+⚠️ **Important**: The private key is only shown once! Save it securely.
+
+## Step 4: Configure in NOFX
+
+Add your agent wallet through the NOFX web interface:
+
+1. Open NOFX dashboard (http://localhost:3000)
+2. Go to **Exchange Configuration**
+3. Enable **Lighter**
+4. Enter:
+   - **Wallet Address**: Your main wallet address (with `0x`)
+   - **Private Key**: Agent private key (remove `0x` prefix)
+5. Save configuration
+
+## Managing Your Agent
+
+### Revoke Agent Access
+
+1. Go to Lighter Settings
+2. Find your agent in the list
+3. Click **Revoke** or **Delete**
+
+### Fund Your Account
+
+1. Deposit supported assets to Lighter
+2. Agent wallet will trade using deposited funds
+
+## Security Best Practices
+
+- Use agent wallet instead of main wallet private key
+- Store agent private key securely
+- Revoke unused agents
+- Monitor agent activity regularly
+- Keep main wallet funds separate from trading funds
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| Agent not working | Check if agent is still active |
+| Invalid signature | Ensure private key doesn't have `0x` prefix |
+| Insufficient funds | Deposit funds to your Lighter account |
+| Connection error | Check network settings |
