How to extract the contract address from an ERC20 token owned by a user using Ethers.js

index.jsx

import { ethers } from 'ethers';

const ERC20_ABI = ... // Replace with the ABI of your ERC20 token

async function getContractAddress(tokenAddress, userAddress) {
  const provider = new ethers.providers.InfuraProvider('mainnet', 'YOUR_INFURA_PROJECT_ID');

  const contract = new ethers.Contract(tokenAddress, ERC20_ABI, provider);
  const balance = await contract.balanceOf(userAddress);

  console.log(`Contract address of ${tokenAddress}: ${contract.address}`);
}

getContractAddress('0x123...', '0x456...');

/*In this example, we are creating a new ethers.Contract instance with the ERC20 token's ABI and address.
*We can then use the contract.address property to retrieve the contract address of the ERC20 token.
*Note that we are using ethers.providers.InfuraProvider as the provider for the ethers.js library. 
*This allows us to connect to the Ethereum network using Infura, which provides a reliable and stable API
*endpoint for interacting with the network.
