Get ETH Balance with Ethersjs

Question

I'm trying to get the balance of my wallet address to render on my frontend. Here's what I have so far.


const [balance, setBalance] = useState("");

const handleWalletBalance = async () => {
      const { ethereum } = window;
      
      if(ethereum) {
        const balance = await ethereum.request({method: 'eth_getBalance'})
        const provider = new ethers.providers.Web3Provider(ethereum)
        await provider.getBalance(balance)
        setBalance(balance)
        console.log(balance)
     }
  }

The error I'm getting is MetaMask - RPC Error: missing value for required argument 0 .

I'm using a method for querying accounts. What am I missing?

You can use:

const getBalance = async (address) => {
    const provider = new ethers.providers.Web3Provider(window.ethereum);
    const balance = await provider.getBalance(address);
    const balanceInEth = ethers.utils.formatEther(balance);
    console.log(balanceInEth);
}

You set the provider, then you ask for balance through the provider (account must be logged in), and finally you format the result of BigNumber to Eth.

this is correct answer, but often when a network halted or error, the balance is not visible in the console. the solution is replace rpc node or use another network – alvin Christianto Apr 18 '23 at 02:16

I think that you need to specify the account you want to use from your MetaMask. You can do it with the following code.

const provider = new ethers.providers.Web3Provider(window.ethereum, "any");
const accounts = await provider.send("eth_requestAccounts", []);

Then, to check the balance, you don't need MetaMask, you can do it with the following code.

const balance = await provider.getBalance(accounts[0])
ethers.utils.formatEther(balance)

I know how to get the account. I need to get the balance once I have it. – solidityguy Jan 14 '22 at 01:22
Ahh, I see, I updated my answer to get the account balance. – Rafał Leszko Jan 14 '22 at 09:41
**Error: Objects are not valid as a React child (found: object with keys {_hex, _isBigNumber}). If you meant to render a collection of children, use an array instead.** – solidityguy Jan 17 '22 at 23:17
Is balance a key-value pair? – solidityguy Jan 17 '22 at 23:18
In Etherjs 5, it should be a single value, not an array. https://docs.ethers.io/v5/api/providers/provider/#Provider-getBalance – Rafał Leszko Jan 18 '22 at 08:25
Thanks. Yeah, started with the docs, so I don't know. That's the error I get. – solidityguy Jan 19 '22 at 18:55
