    const Contract = await ContractFactory.deploy(param1, param2, ...) // the constructor params

    await Contract.deployed()

    console.log("Contract deployed to:", Contract.handle)


    // // You may take a look at the perform.

    // let txn = await nftContract.functionName()

    // // Watch for it to be mined.

    // await txn.wait()

    // console.log("perform invoked!")

}


const runMain = async () => {

    attempt {

        await foremost()

        course of.exit(0) // emit the exit occasion that ends all duties instantly, even when there are nonetheless asynchronous operations that haven't been executed. The shell that executed node ought to see the exit code as 0.

    } catch (error) {

        console.log(error)

        course of.exit(1)

    }

}

runMain()

The code supplies a transparent rationalization for the totally different parts with readability. You may make the most of ‘hre.ethers’ for acquiring the contract and deploying it. Nonetheless, it is very important observe sure precautions, reminiscent of,

Refraining from utilizing ‘.sol’ within the ‘your-contract-name’ part in line 2. You may solely use ‘myContract’ on this case. 

Within the subsequent line, it’s important to present all of the parameters wanted for the ‘constructor’ in your sensible contract. 

The traces from 7 to 11 may also help you work together with sensible contracts by invoking the specified features.
