+# Drift Trading Integration
+
+This document explains how to use the Drift trading functionality in the Trading Bot v3.
+
+## Overview
+
+The application now includes integration with Drift Protocol, a decentralized perpetual futures exchange on Solana. This allows you to:
+
+- Connect to your Drift account using your Solana private key
+- View real-time account balance and collateral information
+- Monitor open positions with live P&L calculations
+- Execute trades directly through the interface
+
+## Setup
+
+### 1. Environment Variables
+
+Make sure you have the following environment variables configured in your `.env` file:
+
+```bash
+# Solana/Drift Trading
+SOLANA_RPC_URL=https://api.mainnet-beta.solana.com
+SOLANA_PRIVATE_KEY=[your_solana_private_key_array]
+```
+
+The `SOLANA_PRIVATE_KEY` should be your Solana wallet private key as a JSON array of numbers (not base58 string).
+
+### 2. Drift Account Initialization
+
+Before you can trade, you need to have a Drift account initialized. If you don't have one:
+
+1. Visit [https://app.drift.trade](https://app.drift.trade)
+2. Connect your Solana wallet
+3. Initialize your account by depositing some USDC collateral
+
+## Features
+
+### Account Status Panel
+
+The **Drift Account Status** panel shows:
+
+- **Connection Status**: Whether your wallet is connected to Drift
+- **Wallet Address**: Your Solana public key (truncated for security)
+- **User Account**: Whether your Drift account is initialized
+- **Account Balance**: Real-time collateral and margin information
+- **Open Positions**: All active positions with live P&L
+
+### Trading Panel
+
+The **Drift Trading** panel allows you to:
+
+- **Select Symbol**: Choose from 20+ available markets (SOL, BTC, ETH, etc.)
+- **Choose Side**: Buy (LONG) or Sell (SHORT)
+- **Order Type**: Market or Limit orders
+- **Set Amount**: Trade size in USD
+- **Set Price**: For limit orders only
+
+### Supported Markets
+
+The following markets are currently supported:
+
+- SOLUSD, BTCUSD, ETHUSD
+- DOTUSD, AVAXUSD, ADAUSD
+- MATICUSD, LINKUSD, ATOMUSD
+- NEARUSD, APTUSD, ORBSUSD
+- RNDUSD, WIFUSD, JUPUSD
+- TNSUSD, DOGEUSD, PEPE1KUSD
+- POPCATUSD, BOMERUSD
+
+## API Endpoints
+
+### Login/Authentication
+```
+POST /api/drift/login
+```
+Authenticates your wallet and checks Drift account status.
+
+### Account Balance
+```
+GET /api/drift/balance
+```
+Returns account collateral, margin, and leverage information.
+
+### Positions
+```
+GET /api/drift/positions
+```
+Returns all open positions with real-time P&L.
+
+### Execute Trade
+```
+POST /api/trading
+```
+Executes a trade through Drift Protocol.
+
+**Request Body:**
+```json
+{
+  "symbol": "SOLUSD",
+  "side": "BUY",
+  "amount": 100,
+  "orderType": "MARKET",
+  "price": 45.50
+}
+```
+
+## Testing
+
+You can test the Drift integration using the provided test script:
+
+```bash
+./test-drift-trading.js
+```
+
+This will test:
+1. Login/authentication
+2. Account balance retrieval
+3. Position fetching
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"User account does not exist"**
+   - You need to initialize your Drift account first
+   - Visit app.drift.trade and deposit some USDC
+
+2. **"Failed to login"**
+   - Check your SOLANA_PRIVATE_KEY is correctly formatted
+   - Ensure you have sufficient SOL for transaction fees
+   - Verify your RPC endpoint is working
+
+3. **"Insufficient collateral"**
+   - Deposit more USDC to your Drift account
+   - Reduce your trade size
+
+### Network Issues
+
+If you experience connection issues:
+- Try switching to a different Solana RPC endpoint
+- Check if Drift Protocol is experiencing downtime
+- Ensure your internet connection is stable
+
+## Security Notes
+
+- Never share your private key
+- The private key is stored securely in environment variables
+- All transactions require your wallet signature
+- The interface only shows truncated public keys
