https://beta.solpg.io/660ce716cffcf4b13384d010

Starter Code

  • open solana playground
  • starter code
client.ts
import {
  ACCOUNT_SIZE,
  TOKEN_2022_PROGRAM_ID,
  createInitializeAccountInstruction,
  getMinimumBalanceForRentExemptAccount,
  createMint,
} from "@solana/spl-token";
import {
  Connection,
  Keypair,
  SystemProgram,
  Transaction,
  clusterApiUrl,
  sendAndConfirmTransaction,
} from "@solana/web3.js";
 
const wallet = pg.wallet;
const connection = new Connection(clusterApiUrl("devnet"), "confirmed");
 
// Create new mint account
const mint = await createMint(
  connection,
  wallet.keypair, // payer
  wallet.publicKey, // mint authority
  wallet.publicKey, // freeze authority
  2, // decimals
  new Keypair(), // keypair for mint account
  null, // confirmOptions
  TOKEN_2022_PROGRAM_ID,
);

Generate Keypair

client.ts
// Generate keypair to use as address of token account
const token = Keypair.generate();
 
// Calculate minimum lamports for space required by token account
const rentLamports = await getMinimumBalanceForRentExemptAccount(connection);

Build Create Account Instruction

client.ts
// Instruction to create new account with space for new token account
const createAccountInstruction = SystemProgram.createAccount({
  fromPubkey: wallet.publicKey,
  newAccountPubkey: token.publicKey,
  space: ACCOUNT_SIZE,
  lamports: rentLamports,
  programId: TOKEN_2022_PROGRAM_ID,
});

Build Initialize Account Instruction

client.ts
// Instruction to initialize token account
const initializeAccountInstruction = createInitializeAccountInstruction(
  token.publicKey, // token account address
  mint, // mint address
  wallet.publicKey, // token account owner
  TOKEN_2022_PROGRAM_ID,
);

Add Instructions to Transaction

client.ts
const transaction = new Transaction().add(
  createAccountInstruction,
  initializeAccountInstruction,
);

Send Transaction

client.ts
const transactionSignature = await sendAndConfirmTransaction(
  connection,
  transaction,
  [
    wallet.keypair, // payer
    token, // token address keypair
  ],
);
client.ts
console.log(
  "\nTransaction Signature:",
  `https://explorer.solana.com/tx/${transactionSignature}?cluster=devnet`,
);
 
console.log(
  "\nToken Account: ",
  `https://explorer.solana.com/address/${token.publicKey}?cluster=devnet`,
);
