I can provide an example article on how to get mint account details using Web3.js V2 and the @solana-program/token-programs library.
Fetching Mint Account Details Using Web3.js V2 and @solana-program/token-programs
In this article, we will explore how to get mint account details using the new Solana web3.js V2 and the @solana-program/token-programs library. We will cover the steps to create a token program, deploy it to Solana, and then use Web3.js to get mint account details.
Prerequisites
- Solana CLI installed
- Node.js installed
- Web3.js installed
Step 1: Create a Token Program
A token program is an extension to 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-example-program
cd solana-token-example-program
npm initialize -y
Install the required dependencies:
npm install @solana-program/token-programs
Create a file called token-program.json and add the following code:
{
"name": "MyToken",
"author": {
"id": "username"
},
"description": "A simple example token program"
}
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..."
run solo --type script deploy --name MyToken \
solana-program(token-programs) --datafile token-program.json \
--account-name accounts/0 --script-script my-token-script.js
This will create a new deployment of the token program to Solana.
Step 3: Create an Account
To get the mint account details, we need to create a custom account that contains the tokens. We will use the @solana-program/token-programs library again.
Create a file called create-account.sh and add the following code:
#!/bin/sh
echo "Creating custom account..."
run solo --type script deploy \
solana program (token programs) --name MyAccount --datafile create-account.json \
--account-name accounts/1 --script-script my-account-script.js
This will create a new custom account that contains the tokens.
Step 4: Fetch Mint Account Details
To get mint account details, we will use Web3.js to interact with Solana. Create a file called fetch-mint-account.sh and add the following code:
#!/bin/sh
echo "Fetching mint account details..."
const web3 = require('web3');
const accounts = await web3.eth.accounts.get();
const tokenProgramAddress = 'some-token-program-address'; // Replace with your token program address
const transaction = {
from: 'your-username',
to: accounts[0].address, // Replace with your custom account address
value: web3.utils.toWei(1, 'ether'), // Replace with the amount of tokens you want to transfer
gas limit: 20,000,
};
web3.eth.sendTransaction(transaction)
.then((transactionReceipt) => {
console.log(Mint Account Details:, transactionReceipt);
})
.catch((error) => {
console.error('Error fetching mint account details:', error);
});
This will create a new transaction to fetch the mint account details and sign it using Web3.js.
Putting it all together
Here’s an example of how you can put it all together:
./create-account.sh
./fetch-mint-account.sh
Replace MyAccount with your custom account name, some-token-program-address with your token program address, and your-username with your Solana username.
This will create a new custom account that contains the tokens and then fetch the mint account details using Web3.js.
