#1

So my Dapp right now operates on Polygon Mumbai Network
and i try to get user balance by running this function

const fetchTokenBalances = async () => {
    const options = {
      chain: "mumbai",
      address: walletAddress
    };
    const balances = await Web3Api.account.getTokenBalances(options);
  };

i already connected to metamask

anyone can help me? thanks!

you can try to use console log to see what are the values sent to web3api, you can also look in network tab, you can also try directly in web3api interface: https://admin.moralis.io/web3apis
