Lesson 6: New deployment via Hardhat due to new updates

[DylanMaas]

Hi all,

I am currently at lesson 6, and getting some issues with the deploy.js file regarding the .deployed() function. However, after looking through the internet it seems that this happens due to some new hardhat updates.

When looking at their documentation, they say this now for deploying a contract, using the .deployContract() and .waitForDeployment() functions: https://hardhat.org/hardhat-runner/docs/guides/deploying. In addition, I found this article: https://dev.to/muratcanyuksel/deploying-smart-contracts-with-the-new-hardhat-update-576i

Based on this, I have updated my deploy.js file accordingly to import hre and run the updated code:

// imports
const hre = require("hardhat")

// async main function
async function main() {
    const SimpleStorage = await hre.ethers.deployContract("SimpleStorage")
    console.log("Deploying Contract...")
    await SimpleStorage.waitForDeployment()
    console.log(`Deployed contract to: ${SimpleStorage.target}`)
}

// main
main()
    .then(() => process.exit(0))
    .catch((error) => {
        console.error(error)
        process.exit(1)
    })

Could anyone check or confirm that this is right? This new code seems to be running fine, and the old code is not working for me. I am curious if my research was right and that this approach does not hamper progress in future sections. Thanks in advance!

Thanks for your response! Code is working indeed, but due to my inexperience I was curious if this would be the right way based on the current Hardhat version, and if it would hamper future progress in other lessons since it's different from Patrick's code!

Ok, that’s great.
The big issue is with ethers package, there are two versions V5 and V6.
I suggest you use ethersV5 instead of ethersV6, to follow along with the course.
