Offline Payment Vouchers

Demo: https://voucher-84h8hn.spheron.app/

Pay offline using Polygon Payment Vouchers:

1. Login using your Metamask wallet.
2. Generate payment vouchers (it will lock your funds in the smart contract).
3. Send link or show QR-code to make a payment.

Quick Start (run this project locally)

Step 0: Prerequisites: Make sure you've installed Node.js ≥ 12

Step 1: Create .env on the root dir. && enter all configs using env.example

Step 2: Install dependency

yarn install or npm install

Step 3: Deploy contract to Mumbai Testnet

yarn deploy:mumbai or npm deploy:mumbai

Step 4: Run frontend locally

yarn start or npm start

As you can see in package.json, this does two things:

1. builds & deploys smart contract to Mumbai TestNet
2. builds & run frontend code on localhost

Go ahead and play with the app and the code. As you make code changes, the app will automatically reload. Every smart contract in Polygon has its [own associated account]. When you run deploy:mumbai, your smart contract gets deployed to the Mumbai Test Network TestNet with a throwaway account.
