Lesson 6: Can not deploy on Arbitrum

[nugen0x]

Hi, on the 6th lesson/Networks in Hardhat section, I wanted to add Arbitrum network. Code works. But the given tx hash is giving me an empty page on arbiscan.

What I ran: yarn hardhat run scripts/deploy.js --network arbitrum

What I expected: Fail transaction due to not having any ETH on Arbitrum or similar.

What I got:

DEPLOYING CONTRACT...
Deployed contract to: 0x4663Ec474D1405af79148cC2AD79a1f9543Cc566
Current value is: 0.
Updated value is: 7.
✨  Done in 30.82s.

but this 0x hash above, is not giving anything on Arbiscan eventhough I run --network arbitrum . I am only getting tx details on sepolia etherscan.

What is the reason that I can not deploy to Arbitrum?

deploy.js

//  imports
const { ethers, run, network } = require("hardhat");
//  async main
async function main() {
  const SimpleStorageFactory = await ethers.getContractFactory("SimpleStorage");
  console.log("DEPLOYING CONTRACT...");
  const simpleStorage = await SimpleStorageFactory.deploy();
  await simpleStorage.deployed();
  console.log(`Deployed contract to: ${simpleStorage.address}`);
  if (network.chainId === 11155111 && process.env.ETHERSCAN_API_KEY) {
    console.log("Waiting for block txs");
    await simpleStorage.deployTransaction.wait(6);
    await verify(simpleStorage.address, []);
  }

  const currentValue = await simpleStorage.retrieve();
  console.log(`Current value is: ${currentValue}.`);

  //  update the current value
  const txResponse = await simpleStorage.store(7);
  await txResponse.wait(1);
  const updatedValue = await simpleStorage.retrieve();
  console.log(`Updated value is: ${updatedValue}.`);
}

//  verify
async function verify(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.");
    }
    console.log(e);
  }
}

//  call

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

Oh my god, I've just realized I've assigned ARBITRUM_RPC_URL to process.env.SEPOLIA_RPC_URL.

After fixing the error, I got: Error: insufficient funds for intrinsic transaction cost

Looked for the delete discussion button but could not find it. Therefore I'm gonna mark it as resolved.

Sorry for the headache folks 🙋🏻‍♂️
