Here is a step-by-step article on how to create 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 knowledge 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
- A 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.js
package provides the Solana CLI and web3.js libraries, which we will use to interact with the Solana blockchain.
Step 2: Create a new Solidity contract
Create a new file called contract.solidity
:
touch contract.solidity
Open this file in VSCode and add the following code:
pragma solidity ^0.8.0;
import "
contract SPLToken {
// Set the token name, symbol, and total supply
string public name = "My SPL Token";
string public symbol = "SPLT";
uint public totalSupply;
// Constructor function to initialize token metadata
constructor() {
// Initialize the total supply of the token
totalSupply = 1000;
}
// Function to mint a new token
function mint(address recipient, uint amount) public {
// Check if the sender has sufficient funds
require(msg.sender.hasBalance(), "Insufficient funds");
// Mint the token for the recipient
_mint(msg.sender, amount);
}
}
This contract defines the basic structure of an SPL token with a name, symbol, and total supply. The mint
function allows users to mint new tokens.
Step 3: Compile and Deploy the Contract
Compile and deploy your contract:
cd solana-token
npx solana-compile --bin contract.solidity
This command compiles your Solidity code into a Solana program that can be deployed to the blockchain.
Step 4: Use the Contract in Visual Code
Create a new file called index.sol
and add the following code:
import "
contract Main {
// Import the SPLToken contract
using SafeERC20 for (address, address);
// Initialize the variables
uint public balance;
// Function to mint a new token
function mint(address recipient, uint amount) public {
// MINT THE TOKEN FOR 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 called main.ts
and 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 = await getAccount();
console.log(‘Current balance:’, account.
