Deploy (Polygon Amoy)

npm run deploy:amoy

This command will:

1. Deploy contracts to Amoy.
2. Verify contracts on PolygonScan (if API key provided).
3. Print the deployed addresses.

Frontend

Update Contract Integration

After deployment, run the ABI extraction script to update the frontend with the new ABIs:

node scripts/extract-abi.js

Then update frontend/.env.local with the new contract addresses.

Run Locally

cd frontend
npm run dev

Deployment (Vercel)

The frontend is ready for deployment on Vercel.

1. Push this repository to GitHub.
2. Import the project in Vercel.
3. Set the Root Directory to frontend.
4. Add the Environment Variables from frontend/.env.local to Vercel Project Settings.
