Invalid address or ENS name

Question

I can't understand what the problem is. When I am run the app I am getting this error:

Unhandled Runtime Error
Error: invalid address or ENS name (argument="name", value=5.050201689117535e+47, code=INVALID_ARGUMENT, version=contracts/5.5.0)

My code is given below:

import {ethers} from 'ethers'
import {useEffect, useState} from 'react'
import axios from 'axios'
import Web3Modal from 'web3modal'

import { nftaddress, nftmarketaddress } from '../config'

import NFT from '../artifacts/contracts/NFT.sol/NFT.json'
import Market from '../artifacts/contracts/Market.sol/Market.json'

export default function Home() {
  const [nfts, setNFts] = useState([])
  const [loadingState, setLoadingState] = useState('not-loaded')

  useEffect(()=> {
    loadNFTs()
  }, [])

  async function loadNFTs() {
    // what we want to load:
    // ***provider, tokenContract, marketContract, data for our marketItems***

    const provider = new ethers.providers.JsonRpcProvider()
    const tokenContract = new ethers.Contract(nftaddress, NFT.abi, provider)
    const marketContract = new ethers.Contract(nftmarketaddress, Market.abi, provider)
    const data = await marketContract.fetchMarketTokens()

    const items = await Promise.all(data.map(async i => {
      const tokenUri = await tokenContract.tokenURI(i.tokenId)
      // we want get the token metadata - json 
      const meta = await axios.get(tokenUri)
      let price = ethers.utils.formatUnits(i.price.toString(), 'ether')

Answer 1

I had exactly the same error message. The problem is your value for nftmarketaddress is most likely invalid.

This is what it should look like:

export const nftmarketaddress = "0xcd3b766ccdd6ae721141f452c550ca635964ce71"

Exported as a string.

In my case I had an empty space after the opening quotation mark.

export const nftmarketaddress = " 0xcd3b766ccdd6ae721141f452c550ca635964ce71"

The error means the address you are passing is not in the right format hence presenting as an INVALID_ARGUMENT. It needs to be in the format 0xcd3b766ccdd6ae721141f452c550ca635964ce71(42 hexadecimal characters) and as mentioned above exported as a string.

Answer 2

I got this error while passing in the addresses as parameters to the contract. What solved the problem was:

const [deployer, acc1, acc2] = await ethers.getSigners();

and then at the contract constructor, I called:

acc1.address, acc2.address 

Instead of:

acc1,acc2

So make sure you've got the .address at the end of each account.

Answer 3

I run into this error while trying to deploy using hardhat. Here is the fix

  const charityWallet = signers[1]
  const marketingWallet =signers[2]

  
  //We Deploy
  const givers = await Givers.deploy(charityWallet.address,marketingWallet.address,process.env.ROUTER02);

Answer 4

I did a mistake while passing the contract address I passed it as a number and that was the issue. ( do NOT do this )

This is the correct way

const contract = await ethers.getContractAt("Token","ADDRESS_OF_WALLET")

Now you can invoke the functions like this

await contract.name()

Answer 5

From reading the other answers and resolving this issue when I encountered it, it seems to me that this error means you are passing a value which is not formatted as an Ethereum address into a function which expects an Ethereum address, i.e.

• What you are passing is not an address but a different object (in my case a "Signer" object which contained an address and its private key as members) or
• Your address is formatted incorrectly (for example, with extra whitespace or as a number).

Answer 6

I get this error by passing an undefined element to a estimateGas Contract function when an address was expected. So if anybody else has this error, check the functions params too.
