Lesson 6 : Contract not verifying

[nishaniyaz]

Hi,
In lesson 6 after deploying the contract to test net goerli, my contract is deploying properly, but it is not verified.

Deploying Contract Please wait.....
Deployed Contract to: 0x1eBd4b7BC00eC9915209b8cE50ca9D44404EDA69
Current Value is : 0
Updated Value is : 7
Done in 37.77s.

No verification is done.
can anyone help me in this.

My code for deploy.js is below

const { ethers, run, network } = require("hardhat")

//async  main
async function main() {
    const SimpleStorageFactory = await ethers.getContractFactory(
        "SimpleStorage"
    )
    console.log("Deploying Contract Please wait.....")
    const simpleStorage = await SimpleStorageFactory.deploy()
    await simpleStorage._deployed()
    console.log(`Deployed Contract to: ${simpleStorage.address}`)
    if (network.config.chainId === 5 && process.env.ETHERSCAN_API_KEY) {
        console.log(`Waiting for block confirmations....`)
        await simpleStorage.deployTransaction.wait(6)
        await verify(simpleStorage.address, [])
    }
    //interacting with the contract
    const currentValue = await simpleStorage.retrieve()
    console.log(`Current Value is : ${currentValue}`)

    //updating the favorite number in our contract
    const transactionResponse = await simpleStorage.store(7)
    await transactionResponse.wait(1)
    const updatedValue = await simpleStorage.retrieve()
    console.log(`Updated Value is : ${updatedValue}`)
}
//async function verify(contractAddress, args) {
const verify = async (contractAddress, args) => {
    console.log("verifying Contract.......")
    try {
        await run("verify:verify", {
            address: contractAddress,
            constructorArguments: args,
        })
    } catch (e) {
        if (e.message.toLowerCase().includes("already verified")) {
            console.log("Already verified!")
        } else {
            console.log(e)
        }
    }
}

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

Hey @nishaniyaz are you sure you were deploying with the flag --network goerli? if not, please make sure you do so. And also check your hardhat.config.js file in the networks section if you have set chainId for goerli to 5

[nishaniyaz]

hey @othaime-en. thank you for your reply. yes i deployed with the flag network goerli. my contract is deployed even my goerli eth is getting reduced from my metamask account. Also if i copy the contract address which is deployed and check it in ether scan, it shows the transaction in ether scan. but it is not getting verified.

here is my hardhat.config.js

require("@nomicfoundation/hardhat-toolbox");
require("dotenv").config();
require("@nomiclabs/hardhat-etherscan");
/** @type import('hardhat/config').HardhatUserConfig */

const GOERLI_RPC_URL = process.env.GOERLI_RPC_URL;
const PRIVATE_KEY = process.env.PRIVATE_KEY;
const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY;

module.exports = {
  defaultNetwork: "hardhat",
  networks: {
    goerli: {
      url: GOERLI_RPC_URL,
      accounts: [PRIVATE_KEY],
      chainid: 5,
    },
  },
  solidity: "0.8.17",
  etherscan: {
    apiKey: ETHERSCAN_API_KEY,
  },
};

Hey @nishaniyaz make this correction. You should use chainId: 5 not chainid: 5. (The I in Id should be capitalized)

[othaime-en]

You see, this line if (network.config.chainId === 5 && process.env.ETHERSCAN_API_KEY) { was trying to find where chainId in your hardhat.config.js was 5. But you only had chainid not chainId so the entire block necessary to verify your contract wasn't getting executed because the if statement was wrong.

hi @othaime-en.
Thank you very much for finding my mistake.
It worked now. I will be more cautious in future to avoid such mistakes.
Thank you once again @othaime-en
