BALANCING TOKENS ON SOLANA with 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 encounter issues with getting token balances. In this article, we’ll explore the correct ways to get token balances on Solana Using Web3.JS V2.

why Connection.gettokenacountsbyowner () is no longer available

Before diving into the solution, it’s essential to understand why the Old API (Connection.Gettokenaccountsbyowner ()) has been deprecated. The rpc object in web3.js v1 include a method called

Solution 1: Using the new GetTokenacountsbyowner 'API

In web3js@2, theGetTokenaccountsbyowner ‘function is available. You can use it to retrieve token balances for a specific owner.

`JavaScript

Const Connection = New Web3 (New Web3.Providers.httprovider ("

const solanawallet = await connection.get wallet ();

Const accounts = await solanawallet.gettokenacountsbyowner (youraccountaddress);

Replace Your_account_address with the actual address of your Solana Wallet.

Solution 2: Using the RPC Endpoint

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

`JavaScript

Const Connection = New Web3 (New Web3.Providers.httprovider ("

const solanawallet = await connection.get wallet ();

const rpcendpoint = "

Const rpcoptions = {{

Method: "Get",

Params: [

Accounts 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 a RPC endpoint provided by the Solana Network. You can find the RPC endpoint for your specific Solana Wallet Address.

tips and variations

• Make sure to use the correct rpc object, which ishttps: // api.manet.dev/solana.

• If you’re using a non-mainet wallet address, replace `YouracCountaddress’ with the actual address of your wallet.

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

By following these steps, you should be able to get token balances on Solana using web3.js v2 successfully. Remember to check the official documentation for more information and updates to the API. Happy Coding!
