How to Create a Token Account

A token account is required for a user to hold tokens.

A user will have at least one token account for every type of token they own.

Associated Token Accounts are deterministicly created accounts for every keypair. ATAs are the recommended method of managing token accounts.

import {
clusterApiUrl,
Connection,
PublicKey,
Keypair,
Transaction,
sendAndConfirmTransaction,
} from "@solana/web3.js";
import {
createAssociatedTokenAccount,
getAssociatedTokenAddress,
createAssociatedTokenAccountInstruction,
} from "@solana/spl-token";
import bs58 from "bs58";

(async () => {
// connection
const connection = new Connection(clusterApiUrl("devnet"), "confirmed");

const mintPubkey = new PublicKey(

// 1) use build-in function

// 2) composed by yourself
{
// calculate ATA
let ata = await getAssociatedTokenAddress(
mintPubkey, // mint
alice.publicKey, // owner

console.log(`ATA: ${ata.toBase58()}`);

// if your wallet is off-curve, you should use
// let ata = await getAssociatedTokenAddress(
// mintPubkey, // mint
// alice.publicKey // owner
// true, // allowOwnerOffCurve
// );

let transaction = new Transaction().add(
createAssociatedTokenAccountInstruction(
feePayer.publicKey, // payer
ata, // ata
alice.publicKey, // owner
mintPubkey, // mint
),
);

const signature = await sendAndConfirmTransaction(

transaction,
[feePayer], // Signers
);

console.log(`txhash: ${await signature}`);
}
})();
