## 🚀 How to Use

### Test the Frontend
1. Open http://localhost:3000 in your browser
2. Connect MetaMask or use a web3 provider
3. Use one of the test account private keys to sign in

### Test the API
```bash
# Health check
curl http://localhost:5000/api/health

# Dashboard stats
curl http://localhost:5000/api/dashboard/comprehensive-stats
```

### Test Smart Contract Interaction
```bash
# Check contract details
curl -X POST http://127.0.0.1:8545 \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_getCode","params":["0x5FbDB2315678afecb367f032d93F642f64180aa3","latest"],"id":1}'
```

## 🛑 Stopping Services

### Stop All Services Gracefully
```bash
# Backend (if running in terminal)
# Press Ctrl+C

# Frontend (if running in terminal)
# Press Ctrl+C

# Anvil (if running in terminal)
# Press Ctrl+C

# MongoDB
killall mongod

# Or stop individual processes
pkill -f "python3.*main.py"
pkill -f "next dev"
pkill anvil
killall mongod
```

### Restart Services

#### Terminal 1: MongoDB
```bash
mongod --dbpath ~/mongodata --logpath /tmp/mongodb.log
```

#### Terminal 2: Anvil
```bash
export PATH="/home/w4nn4d13/.foundry/bin:$PATH"
anvil
```

#### Terminal 3: Backend
```bash
cd /home/w4nn4d13/Project/OpenLearnX/backend
source venv/bin/activate
python3 main.py
```

#### Terminal 4: Frontend
```bash
cd /home/w4nn4d13/Project/OpenLearnX/frontend
pnpm dev
```

## 📝 Troubleshooting

### Port Already in Use
```bash
# Find process on port
lsof -i :5000    # Backend
lsof -i :3000    # Frontend
lsof -i :8545    # Anvil
lsof -i :27017   # MongoDB

# Kill process
kill -9 <PID>
```

### MongoDB Connection Error
```bash
# Restart MongoDB
pkill mongod
rm -rf ~/mongodata/mongod.lock
mongod --dbpath ~/mongodata
```

### Frontend Build Issues
```bash
cd frontend
rm -rf .next node_modules pnpm-lock.yaml
pnpm install
pnpm dev
```

### Backend Import Errors
```bash
cd backend
source venv/bin/activate
pip install -r ../requirements.txt
```

## 🔐 Security Notes

⚠️ **IMPORTANT FOR PRODUCTION:**
- These are development credentials with default secrets
- NEVER use these in production environments
- Change `SECRET_KEY` and `JWT_SECRET_KEY`
- Update MetaMask networks with real RPC endpoints
- Configure proper environment variables
- Use a real database (not localhost)
- Enable HTTPS/SSL

---

## ✅ Deployment Complete!

Your OpenLearnX platform is now running on localhost. You can:
- Develop and test features
- Make API calls from applications
- Deploy smart contracts
- Create and manage certificates
- Test the full application flow

**Happy coding! 🎉**
