What is @solana/spl-token?

@solana/spl-token is an npm package that provides a set of tools and utilities for interacting with the Solana blockchain's SPL Token program. This package allows developers to create, manage, and interact with SPL tokens, which are the standard tokens on the Solana blockchain.

What are @solana/spl-token's main functionalities?

Create a New Token

This feature allows you to create a new SPL token on the Solana blockchain. The code sample demonstrates how to set up a connection to the Solana network, generate keypairs for the payer, mint authority, and freeze authority, and then create a new token with specified decimal places.

const { Connection, Keypair } = require('@solana/web3.js');
const { createMint } = require('@solana/spl-token');

(async () => {
  const connection = new Connection('https://api.mainnet-beta.solana.com');
  const payer = Keypair.generate();
  const mintAuthority = Keypair.generate();
  const freezeAuthority = Keypair.generate();

  const mint = await createMint(
    connection,
    payer,
    mintAuthority.publicKey,
    freezeAuthority.publicKey,
    9 // Decimals
  );
  console.log('Created new token:', mint.toBase58());
})();

Create a Token Account

This feature allows you to create a new token account for a specific SPL token. The code sample demonstrates how to set up a connection, generate keypairs for the payer, mint, and owner, and then create a new token account associated with the specified mint and owner.

const { Connection, Keypair } = require('@solana/web3.js');
const { createAccount } = require('@solana/spl-token');

(async () => {
  const connection = new Connection('https://api.mainnet-beta.solana.com');
  const payer = Keypair.generate();
  const mint = Keypair.generate(); // Assume this is your token mint
  const owner = Keypair.generate();

  const tokenAccount = await createAccount(
    connection,
    payer,
    mint.publicKey,
    owner.publicKey
  );
  console.log('Created new token account:', tokenAccount.toBase58());
})();

Mint New Tokens

This feature allows you to mint new tokens to a specified token account. The code sample demonstrates how to set up a connection, generate keypairs for the payer, mint, destination account, and mint authority, and then mint a specified amount of tokens to the destination account.

const { Connection, Keypair } = require('@solana/web3.js');
const { mintTo } = require('@solana/spl-token');

(async () => {
  const connection = new Connection('https://api.mainnet-beta.solana.com');
  const payer = Keypair.generate();
  const mint = Keypair.generate(); // Assume this is your token mint
  const destination = Keypair.generate(); // Assume this is your token account
  const mintAuthority = Keypair.generate();

  await mintTo(
    connection,
    payer,
    mint.publicKey,
    destination.publicKey,
    mintAuthority,
    1000000 // Amount to mint
  );
  console.log('Minted new tokens');
})();

Transfer Tokens

This feature allows you to transfer tokens from one token account to another. The code sample demonstrates how to set up a connection, generate keypairs for the payer, source account, destination account, and owner, and then transfer a specified amount of tokens from the source account to the destination account.

const { Connection, Keypair } = require('@solana/web3.js');
const { transfer } = require('@solana/spl-token');

(async () => {
  const connection = new Connection('https://api.mainnet-beta.solana.com');
  const payer = Keypair.generate();
  const source = Keypair.generate(); // Assume this is your source token account
  const destination = Keypair.generate(); // Assume this is your destination token account
  const owner = Keypair.generate();

  await transfer(
    connection,
    payer,
    source.publicKey,
    destination.publicKey,
    owner,
    500000 // Amount to transfer
  );
  console.log('Transferred tokens');
})();
