Lesson 6 Insufficient Funds Error

[0xjakefromstatefarm]

Hi Everyone!

after running:
yarn hardhat run scripts/deploy.js --network rinkeby

I received the error:

Error: insufficient funds for intrinsic transaction cost [ See: https://links.ethers.org/v5-errors-INSUFFICIENT_FUNDS ] (error={"name":"ProviderError","code":-32000,"_isProviderError":true}, method="sendTransaction", transaction=undefined, code=INSUFFICIENT_FUNDS, version=providers/5.6.8)

My alchemy node also shows the same error:

I have 0.7 Rinkeby ETH in my metamask and tried pasting the raw private key into the hardhat config file but still ran into the same error.

This is my deploy script:

// imports
const { ethers } = 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}`)
}
//main call

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

This is my hardhat config file:

require("@nomicfoundation/hardhat-toolbox")
require("dotenv").config()

/** @type import('hardhat/config').HardhatUserConfig */

const RINKEBY_RPC_URL = process.env.RINKEBY_RPC_URL
const PRIVATE_KEY = process.env.PRIVATE_KEY

module.exports = {
  defaultNetwork: "hardhat",
  networks: {
    rinkeby: {
      url: RINKEBY_RPC_URL,
      accounts: [PRIVATE_KEY],
      chainId: 4,
    },
  },
  solidity: "0.8.8",
}

Any ideas on how I can fix this?

@masonjake try to console log the private key and rinkeby URL and see the results.

[0xjakefromstatefarm]

They both return the correct values

[alymurtazamemon]

@masonjake let's try to add these in rinkeby object.

gas: 2100000,
gasPrice: 8000000000,

Just tried, it still throws the same error

If you have not been able to solve yours, kindly follow this procedure:

1. Make sure your .env file contain the correct private key and rpc url
2. deleter your ".encryptedKey.json" file as its contains the previous wallet security key.
3. then deploy your encryptKey.js, it will generate the new .encryptedKey.json.
4. then update your deploy.js file with this

const contract = await contractFactory.deploy({ gasLimit: 3000000 })
await contract.deployTransaction.wait(1)

I have the same error when testing with goerli testnet. Can anybody help with a solution?

[Adekokoka]

@genadiN Can you check if you have sufficient funds in your wallet for deploying contract?
