Starter React Typescript Ethers.js Hardhat Project

This repo contains a Hardhat and React Dapp starter project. The React Dapp in the frontend dir of this repo interacts with Hardhat's example Greeter.sol smart contract running on a local blockchain. The Hardhat Greeter.sol example contract is the boilerplate contract that Hardhat creates when creating a new Hardhat project via yarn hardhat init.

The React Dapp in this repo looks like this:

The Dapp uses the @web3-react npm package's injected web3 provider to connect to MetaMask and demonstrates the following functionality:

• Connecting a Dapp to the blockchain
• Reading account data from the blockchain
• Cryptographically signing digital messages
• Deploying new instances of a smart contract
• Reading and writing data to and from the deployed smart contract

This repo can be useful to anyone looking to get a local Ethereum blockchain running and to get a Dapp up and communicating with the local node quickly.

Additionally, this repo is a companion project to ChainShot's How to Build a React Dapp with Hardhat and MetaMask Medium article. The article and this GitHub repo are recommended for anyone wanting to build up their web3 skills and are helpful resources for anyone interested in joining any of ChainShot's bootcamps.

The smart contract and Hardhat node part of this project were created by installing the Hardhat npm package and bootstrapping a Hardhat project by running: yarn hardhat init. For more details you can read more in the Hardhat README doc. The frontend part of this project was created using Create React App.

Pull this project down from GitHub, cd into the project directory and run the following commands to get setup and running.

yarn
yarn compile
yarn hardhat node

The commands above will install the project dependencies, compile the sample contract and run a local Hardhat node on port 8545, using chain id 31337.

After running the above tasks checkout the frontend README.md to run a React Dapp using ethers.js that will interact with the sample contract on the local Hardhat node.

Some other hardhat tasks to try out are:

yarn hardhat accounts
yarn hardhat clean
yarn hardhat compile
yarn hardhat deploy
yarn hardhat help
yarn hardhat node
yarn hardhat test
