Official code at: https://github.com/PatrickAlphaC/hardhat-fund-me-fcc

Notes

• using hardhat-toolbox instead of hardhat-waffle
  • this also forces ethers version 6.x instead of 5.x
  • ethers.utils.parseEther was replaced with ethers.parseEther
  • replaced

    fundMe = await ethers.getContract("FundMe", deployer)

    with

    const fundMeDeployment = await deployments.get("FundMe")
    fundMe = await ethers.getContractAt(
        fundMeDeployment.abi,
        fundMeDeployment.address
    )

  • similar replacement for mockV3Aggregator.

  • hardhat-toolbox migration from hardhat-waffle: https://hardhat.org/hardhat-runner/docs/advanced/migrating-from-hardhat-waffle
