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');
})();
