Here is a detailed article on creating an SPL token using Visual Studio Code (VSCode) with the Solana CLI:
Creating an SPL Token Using Visual Code
As you mentioned, Solana is a popular blockchain platform that requires advanced programming skills to create complex tokens. However, with VSCode and the Solana CLI, you can create a simple SPL token in no time.
In this article, we will show you how to use JavaScript, specifically Solidity, to create a basic SPL token on Solana.
Prerequisites
Before you begin, make sure you have:
- Visual Studio Code (VSCode) installed on your WSL (Windows Subsystem for Linux)
- Solana CLI installed and configured
- Solana wallet with sufficient funds
Step 1: Create a new directory and install dependencies
Create a new directory for your project:
mkdir solana-token
cd solana-token
Install the required dependencies:
npm init -y
npm install solana cli @solana/web3.js
The@solana/web3.jspackage provides the Solana CLI and web3.js libraries that we will use to interact with the Solana blockchain.
Step 2: Create a new Solidity contract
Create a new file calledcontract.solidity:
touch contract.solidity
Open this file in VSCode and add the following code:
pragma solidity ^ 0,8,0;
import "
contract SPLToken {
// Define the token name, symbol, and total supply
string public name = "My SPL Token";
string public symbol = "SPLT";
uint public totalSupply;
// Constructor function to initialize the token metadata
constructor() {
// Initialize the total supply of the token
totalsupply = 1000;
}
// Function to mint a new token
function mint(recipient address, uint amount) public {
// Check if the sender has enough funds
require(msg.sender.hasBalance(), "Insufficient funds");
// Coin the token to the recipient
_mint(msg.sender, amount);
}
}
This contract defines the basic structure of an SPL token with a name, symbol, and total supply. The mintfunction allows users to mint new tokens.
Step 3: Build and deploy the contract
Build and deploy your contract:
cd solana-token
npx solana-compile --bin contract.solidity
This command will compile your Solidity code into a Solana program that can be deployed on the blockchain.
Step 4: Use the contract in visual code
Create a new file called "index.sol" and add the following code:
import "
main contract {
// Import the SPLToken contract
using SafeERC20 for (address, address);
// Initialize variables
public balance;
// Function to print a new token
function mint(recipient address, uint amount) public {
// ISSUE A TOKEN TO THE RECIPIENT
balance += amount;
}
// Function to get the user's current balance
function getBalance() public view returns (uint) {
return balance;
}
}
This contract uses the SafeERC20
library to interact with the SPLToken contract. It allows users to mint new tokens and get their current balance.
Step 5: Run the contract in VSCode
Create a new file namedmain.tsand add the following code:
“ typescript
import { Account } from ‘@solana/web3.js’;
import ‘index.sol’;
// Initialize the Solana program
const program = require(‘@sorve/solana-program’);
// Create a new account
async function main() {
const account = wait getAccount();
console.log(‘Current balance:’, account.
