I am trying to deploy and verify my smart contract in the same script deploy.js

[amitx13]

const hre = require("hardhat");
const { mine } = require("@nomicfoundation/hardhat-network-helpers");
require("dotenv").config();
async function main() {
  const contractFactory = await hre.ethers.deployContract("SimpleStorage");
  await contractFactory.waitForDeployment();
  const address = await contractFactory.getAddress();
  console.log(`the contract address of the contract is ${address}`);
  const currentBlock = await hre.ethers.provider.getBlockNumber();
  const targetBlock = currentBlock + 5; // Wait for 5 blocks after the current block

  console.log(
    `Deployed contract at block ${currentBlock}, waiting for block ${targetBlock}...`
  );

  async function mined() {
    await mine(targetBlock);
  }
  await mined();
  console.log("sucessfully_mined :: ");
  await verify(address, []);
}
async function verify(caddress, args) {
  try {
    console.log("verifying...");
    await hre.run("verify:verify", {
      address: caddress,
      constructor: args,
    });
  } catch (er) {
    console.log(er);
  }
}
main()
  .then(() => {
    process.exit(0);
  })
  .catch(() => {
    process.exit(1);
  });

It is working properly till targetblock but it's throwing an error while invoking mined() if you know something please help
note : i am using the latest version of hardhat i.e ^2.17.1 and ethers : ^6.4.0,

• Mining blocks: you can only mine blocks in Hardhat environment, but in test net you have to wait for blocks confirmation (blocks that the others mined and verified)
• Modify the verify function
  constructorArguments: args,

can you please explain it with code

the code, I'm using ethersV5

  const SimpleStorageFactory = await ethers.getContractFactory("SimpleStorage");
  console.log("Deploying contract...");
  const simpleStorage = await SimpleStorageFactory.deploy();
  console.log("Waiting for block confirmations...");
  await simpleStorage.deployTransaction.wait(1);  
  /* After deploying the contract, we have to wait the block to be
   * confirmed, (1 means one block confirmation), 
   * you can change the number of block confirmation to [usually 6 block confirmations] any number
   * but you have to wait until that number of block confirmation.
   * But in Hardhat environment, one block confirmation is enough, or you have to mine the blocks manually 
   */
  await simpleStorage.deployed();
  console.log(`Deployed contract to: ${simpleStorage.address}`);

yah with the help of ethersV5 it can be done but i want to do it with ethersV6 is there any way in V6 to wait for some blocks to get mined

[alfaqi]

I think it will be like this

    const contractFactory = await ethers.getContractFactory("contractName")
    const contract = await contractFactory.deploy()
    await contract.deploymentTransaction().wait(6)
