Solana, with its high throughput and low transaction costs, has emerged as a prominent blockchain for developing decentralized applications using Solana blockchain development services. The Solana Program Library (SPL) facilitates the creation of various tokens, from fungible to non-fungible assets. In this blog, we will explore how to create SPL tokens on Solana using JavaScript.
SPL Token Development
Prerequisites:
- Node.js and npm: Ensure that you have Node.js and npm installed on your machine.
- Solana Wallet: You'll need a Solana wallet to interact with the blockchain. Example - Phantom.
- Code Editor: Choose a code editor of your choice. Example - VS Code.
Getting Started:
Follow the instructions below to create your own SPL tokens on Solana:
- Initialize a Node.js Project:
Create a new Node.js project for creating your spl-token by running the following commands in your terminal:
mkdir solana-spl-token
cd solana-spl-token
npm init -y

- Install Required Packages:
Install the necessary npm packages for interacting with the Solana blockchain
npm install @solana/web3.js @solana/spl-token bs58
- Write token creation script:
Connect to a solana cluster.
const connection = new Connection(
'https://api.devnet.solana.com',
'confirmed'
);
Add your wallet's secret key which will be used to create the token and pay for the network and transaction costs (your wallet needs to have SOL for the network fees).
const privateKey = "˜';
const walletKeypair = Keypair.fromSecretKey(
new Uint8Array(bs58.decode(privateKey))
);
Create a new SPL token using the "createMint" function provided by @solana/spl-token library. We are setting the mint authority and freeze authority of the token to the wallet whose secret key is used above.
const mint = await createMint(
connection,
walletKeypair, // payer
walletKeypair.publicKey, // mint authority
walletKeypair.publicKey, // freeze authority
9 // Decimals for the token
);
Run this command and execute the code to create your SPL token:
node createToken.js
Below is the output:
SPL Token created successfully!
