Solana: Get Mint Account Details using web.3js V2

I can provide you with a sample article on how to get mint account information using Web3.js V2 and the @solana-program/token-programs library.

Getting Mint Account Information Using Web3.js V2 and @solana-program/token-program

In this article, we will explore how to get mint account information using the new Solana web3.js V2 and the @solana-program/token-programs library. We will cover the steps required to create a token program, deploy it to Solana, and then use Web3.js to get mint account information.

Prerequisites

• Sound CLI installed

• Node.js installed

• Web3.js installed

Step 1: Create a Token Program

A Token Program is an extension of the Solana blockchain that allows you to create custom tokens. To create a token program, we will use the “solana-program/token-programs” library.

Create a new directory for your project and initialize it with npm:

mkdir solana-token-program-example
cd solana-token-program-example
npm init -y

Install the required dependencies:

npm install @solanaprogram/tokenprograms

Create a file called “token-program.json” and add the following code:

{
"name": "MyToken"
"author": {
"id": "username"
},
"description": "Simple token program example"
} }

This will create a new token program with a default name, author, and description.

Step 2: Deploy the token program

To deploy the token program to Solana, we will use the “solana-program/token-programs” library. Create a file called “deploy.sh” and add the following code:

#!/bin/sh
echo "Deploying token program..."
solo run -- type script deploy -- name MyToken \
solana-program(token-programs) --data-file token-program.json\;
-- account - name accounts / 0 -- script - script my - token - script . js

This will create a new token program deployment in Solana.

Step 3: Create an account

To get the information about the mint account, we need to create a custom account that contains the tokens. We will again use the “@solana-program/token-programs” library.

Create a file called “create-account.sh” and add the following code:

#!/bin/sh
echo "Creating custom account.
solo run --type script deployment\
solana-program(token-programs) --name MyAccount --data-file create-account.json\
--account-name accounts/1 --script-script my-account-script.js

This will create a new custom account containing tokens.

Step 4: Get Mint Account Information

To get Mint account information, we will use Web3.js to communicate with Solana. Create a file called “fetch-mint-account.sh” and add the following code:

#!/bin/sh
echo "Fetching account information.
const web3 = require('web3');
const accounts = await web3.eth.accounts.get();
const tokenProgramAddress = 'some-token-program-address'; // Replace with the token program address
const transaction = {
from: 'your username',
to: accounts[0].address, // Replace with the custom account address
value : web3.utils.toWei(1, 'ether'), // Replace with the number of tokens you want to transfer
gas limit: 20000,
};
web3.eth.sendTransaction(transaction) .
.then((transactionReceipt) => { .
console.log(Mint account information:, transaction receipt);
})
.catch((error) => { .
console.error('Error importing mint account information:', error);
});

This will create a new transaction to fetch the Mint account information and then sign it using Web3.js.

Putting it all together

Here is an example of how it can be put together:

./create-account.sh
./fetch-mint-account.sh

Replace “MyAccount” with your custom account name, “Some Token-Program-Address” with your Solana username.

This will create a new custom account to store your tokens in, and then fetch your Mint account information using Web3.js.
