Section 2: Write and deploy your WavePortal smart contract to a local Ethereum network

deploy.js

const main = async () => {
  const [deployer] = await hre.ethers.getSigners();
  const accountBalance = await deployer.getBalance();

  console.log('Deploying contracts with account: ', deployer.address);
  console.log('Account balance: ', accountBalance.toString());

  const Token = await hre.ethers.getContractFactory('WavePortal');
  const portal = await Token.deploy();

  console.log('WavePortal address: ', portal.address);
};

const runMain = async () => {
  try {
    await main();
    process.exit(0);
  } catch (error) {
    console.error(error);
    process.exit(1);
  }
};

runMain();

run.js

const main = async () => {
  const [owner, randoPerson] = await hre.ethers.getSigners();
  const waveContractFactory = await hre.ethers.getContractFactory('WavePortal');
  const waveContract = await waveContractFactory.deploy();
  await waveContract.deployed();

  console.log('Contract deployed to:', waveContract.address);
  console.log('Contract deployed by:', owner.address);

  let waveCount;
  waveCount = await waveContract.getTotalWaves();

  let waveTxn = await waveContract.wave();
  await waveTxn.wait();

  waveCount = await waveContract.getTotalWaves();

  waveTxn = await waveContract.connect(randoPerson).wave();
  await waveTxn.wait();

  waveCount = await waveContract.getTotalWaves();
};

const runMain = async () => {
  try {
    await main();
    process.exit(0);
  } catch (error) {
    console.log(error);
