✅ Blockchain immutability
✅ AI verification for fraud prevention
✅ Local-first approach (no external APIs)
✅ MetaMask wallet integration

Note: Test accounts are safe for localhost only. Never use these private keys on mainnet!

🚀 Scaling to Production

To move from localhost to production:

Blockchain: Deploy to Polygon Mumbai/Mainnet
AI: Replace Flask mock with OpenAI/Google Cloud Vision
Storage: Switch to Pinata IPFS or AWS S3
Database: Upgrade to MongoDB Atlas
Hosting: Deploy frontend to Vercel, backend to Render

Estimated production cost: ₹1,850/month

Common Issues

MongoDB not running:
- Windows: net start MongoDB
- Mac/Linux: brew services start mongodb-community
Port conflicts: Check ports 3000, 5000, 8000, 8545 are free
Dependencies: Verify Node.js 18+, Python 3.8+, MongoDB installed
3D scene not visible:
- Ensure WebGL is enabled
- Update graphics drivers
- Try different browser
Animations laggy:
- Close other browser tabs
- Enable hardware acceleration in browser
- Check reduced motion settings

Troubleshooting

Run test-services.bat to verify all services
Run test-typescript.bat to check for TypeScript errors
Check browser console for errors
Ensure MetaMask is installed and configured
