How to Close Token Accounts

You can close a token account if you don't want to use it anymore. There are two situations:

  1. Wrapped SOL - Closing converts Wrapped SOL to SOL
  2. Other Tokens - You can close it only if token account's balance is 0.
import {
clusterApiUrl,
Connection,
PublicKey,
Keypair,
Transaction,
sendAndConfirmTransaction,
} from "@solana/web3.js";
import { closeAccount, createCloseAccountInstruction } from "@solana/spl-token";
import bs58 from "bs58";

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

const feePayer = Keypair.fromSecretKey(
bs58.decode(
"588FU4PktJWfGfxtzpAAXywSNt74AvtroVzGfKkVN1LwRuvHwKGr851uH8czM5qm4iqLbs1kKoMKtMJG4ATR7Ld2",

const alice = Keypair.fromSecretKey(
bs58.decode(
"4NMwxzmYj2uvHuq8xoqhY8RXg63KSVJM1DXkpbmkUY7YQWuoyQgFnnzn6yo3CMnqZasnNPNuAT2TLwQsCaKkUddp",
),
);

const tokenAccountPubkey = new PublicKey(
"2XYiFjmU1pCXmC2QfEAghk6S7UADseupkNQdnRBXszD5",
);

// 1) use build-in function
{
let txhash = await closeAccount(
connection, // connection
feePayer, // payer
tokenAccountPubkey, // token account which you want to close
alice.publicKey, // destination
alice, // owner of token account
);
console.log(`txhash: ${txhash}`);
}

// or

// 2) compose by yourself
{
let tx = new Transaction().add(
createCloseAccountInstruction(
tokenAccountPubkey, // token account which you want to close
alice.publicKey, // destination
alice.publicKey, // owner of token account
),
);
console.log(
`txhash: ${await sendAndConfirmTransaction(connection, tx, [
feePayer,
alice /* fee payer + owner */,
])}`,
);
}
})();
