How to get BNB token balance in metamask wallet in React?

Question

This is snippet of my code.

    const getBalance = (userAddress: String) => {
    const provider = new Web3((window as any).web3.currentProvider);
    const bnbContract = new provider.eth.Contract(bnbTokenAbi, tokenAddress);
    bnbContract.methods.balanceOf(userAddress).call().then((res: any) => {
      setBalance(res);
    }).catch((err: any) => {
      console.log(err);
    });
  }

But only the catch function works, what's the reason?

Answer 1

balanceof is used for any token but bnb or eth and all the main token of the chains correct function is balance address.balance
