Example

import { 
  getBalancesSingleToken,
  getBalanceMultipleTokens,
  getNativePrice,
  getTokensPrice,
} from "@dapp-builder/use-muticall";

const BSC_RPC_URL = "https://bsc-dataseed1.ninicoin.io";

const userAddresses = [
  "0xF977814e90dA44bFA03b6295A0616a897441aceC", // Binance wallet
  "0x8894E0a0c962CB723c1976a4421c95949bE2D4E3", // Binance wallet

const contractTokens = [
  "0x55d398326f99059fF775485246999027B3197955", // USDT
  "0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d", // USDC
];

let balances;

balances = await getBalanceMultipleTokens({
  userAddress: userAddresses[0],
  contractTokens,
  rpcUrl: BSC_RPC_URL,
});

console.log(balances);

balances = await getBalancesSingleToken({
  userAddresses,
  contractToken: contractTokens[0],
  rpcUrl: BSC_RPC_URL
})

console.log(balances);

const price = await getNativePrice(BSC_RPC_URL);
console.log(price.toString())

const tokensPrice = await getTokensPrice(
    [
      "0x3e098C23DCFBbE0A3f468A6bEd1cf1a59DC1770D", // YU
