Token Balance in Solana Using Web3.js v2: A Step-by-Step Guide

Solana is a fast and scalable blockchain platform that has gained popularity in recent years. When it comes to interacting with web3.js, users may face issues while retrieving token balances. In this article, we will explore the proper ways to retrieve token balances in Solana using web3.js v2.

Why connection.getTokenAccountsByOwner() is deprecated

Before diving into the solution, it is very important to understand why the old API (connection.getTokenAccountsByOwner()) is deprecated. The web3.js v1 object rpc includes a method called getTokenAccountsByOwner, which was later renamed to getTokenAccountsByOwner in web3js@2.

Solution 1: Use the new getTokenAccountsByOwner API

The function getTokenAccountsByOwner is available in Web3js@2. You can use it to get the token balances of a specific owner.

const connection = new Web3(new Web3.providers.HttpProvider("
const solanaWallet = await login.get Wallet();
const accounts = await solanaWallet.getTokenAccountsByOwner(YourAccountAddress);

Replace YOUR_ACCOUNT_ADDRESS with the actual Solana wallet address.

Solution 2: Using an RPC Endpoint

You can also get the token balances using the RPC endpoint provided by the Solana network. This method is more verbose, but it is a good alternative.

const connection = new Web3(new Web3.providers.HttpProvider("
const solanaWallet = await login.get Wallet();
const rpcEndpoint = "
const rpcOptions = {
method: "GET",
parameters: [
"account balance ${solanaWallet.address}",
],
};
try {
const response = await fetch(rpcEndpoint, rpcOptions);
const data = JSON.parse(response.text);
console.log(data.balance);
} catch (error) {
console.error(error);
}

Note that this method requires an RPC endpoint provided by the Solana Network. You can find the RPC endpoint for your specific Solana wallet address.

Tips and Variations

• Make sure you are using the correct “rpc” object, which is “

• If you are using a non-mainnet wallet address, replace “YourAccountAddress” with your actual wallet address.

• Be aware of the gas cost when sending transactions. You can adjust the gas limit or transaction fee to optimize performance.

After following these steps, you will be able to successfully receive token balances in Solana using web3.js v2. Don’t forget to read the official documentation for more information and API updates. Happy coding!
