You can clone this repo and get going right away.

Just make sure to:

• run npm install to set up all the dependencies (hardhat, ethers, etc.)
• rename .env-example to .env and then fill in the environment variables with your own info
• set up an Alchemy account here
• set up a Metamask wallet with fake testnet ether

And then you should be able to:

• run npx hardhat run scripts/deploy.js to deploy the contract to the Ropsten testnet
• run npx hardhat run scripts/interact.js to read and write a new message to the smart contract on Ropsten
• run npx hardhat verify --network ropsten <your deplooyment address> 'Hello World!' to verify your contract on Etherscan
