I am still new with web3
How can I get balance of token?
On ropsten network, I have 100 LINK token.
Below is my code
const Web3 = require('web3')
const rpcURL = 'https://ropsten.infura.io/v3/xxxx'
const web3 = new Web3(rpcURL)
let tokenAddress = "0x20fe562d797a42dcb3399062ae9546cd06f63280";
let walletAddress = "0xdD440e8eCA5F1F3e6D5ffE903148EFB374942df2";
// The minimum ABI to get ERC20 Token balance
let minABI = [
// balanceOf
{
"constant":true,
"inputs":[{"name":"_owner","type":"address"}],
"name":"balanceOf",
"outputs":[{"name":"balance","type":"uint256"}],
"type":"function"
},
// decimals
{
"constant":true,
"inputs":[],
"name":"decimals",
"outputs":[{"name":"","type":"uint8"}],
"type":"function"
}
];
let contract = new web3.eth.Contract(minABI,tokenAddress);
async function getBalance() {
balance = await contract.methods.balanceOf(walletAddress);
return balance;
}
console.log(getBalance());
The code return:
Promise { <pending> }
based on my search on google, this promise pending should be solved by using async function but in my case, it still showing promise pending.
I am using latest node 14 and web3.js 1.26
