This is a repository to implements a complete solution based on ReactJS frontend + NodeJS relayer + Solidity Smart Contract to interact with blockchain with gasless policy.

Usage

Before all, install node_modules dependencies in every component that is: root, hardhat folder and frontend folder

• Create .env file and write 2 variables: PROVIDER_URL y ADMIN_PRIVATE_KEY. The first one typically is http://localhost:8545 and the second one is the private key of the relayer account (Account 0 in Hardhat).
• Start NodeJS server in root with npm run server
• Run Hardhat node in ./hardhat with npm run node
• Deploy PointsCounter SC in ./hardhat with npm run deploy
• And finally, in ./frontend start your ReactJS app with npm start

Enjoy!
