How to Use Wrapped SOL
Wrapped SOL just like any other token mint. The difference is using syncNative
and creating token accounts specifically on the NATIVE_MINT
address.
Create Token Account
Like
Create Token Account
but replace mint with NATIVE_MINT
import { NATIVE_MINT } from "@solana/spl-token";
Add Balance
There are two ways to add balance for Wrapped SOL
1. By SOL Transfer
import {
clusterApiUrl,
Connection,
Keypair,
Transaction,
SystemProgram,
sendAndConfirmTransaction,
} from "@solana/web3.js";
import {
NATIVE_MINT,
getAssociatedTokenAddress,
createSyncNativeInstruction,
} from "@solana/spl-token";
import bs58 from "bs58";
(async () => {
// connection
const connection = new Connection(clusterApiUrl("devnet"), "confirmed");
// 5YNmS1R9nNSCDzb5a7mMJ1dwK9uHeAAF4CmPEwKgVWr8
const feePayer = Keypair.fromSecretKey(
bs58.decode(
"588FU4PktJWfGfxtzpAAXywSNt74AvtroVzGfKkVN1LwRuvHwKGr851uH8czM5qm4iqLbs1kKoMKtMJG4ATR7Ld2",
),
);
// G2FAbFQPFa5qKXCetoFZQEvF9BVvCKbvUZvodpVidnoY
const alice = Keypair.fromSecretKey(
bs58.decode(
"4NMwxzmYj2uvHuq8xoqhY8RXg63KSVJM1DXkpbmkUY7YQWuoyQgFnnzn6yo3CMnqZasnNPNuAT2TLwQsCaKkUddp",
),
);
// remember to create ATA first
let ata = await getAssociatedTokenAddress(
NATIVE_MINT, // mint
alice.publicKey, // owner
);
let amount = 1 * 1e9; /* Wrapped SOL's decimals is 9 */
let tx = new Transaction().add(
// trasnfer SOL
SystemProgram.transfer({
fromPubkey: alice.publicKey,
toPubkey: ata,
lamports: amount,
}),
// sync wrapped SOL balance
createSyncNativeInstruction(ata),
);
console.log(
`txhash: ${await sendAndConfirmTransaction(connection, tx, [feePayer, alice])}`,
);
})();
2. By Token Transfer
import {
clusterApiUrl,
Connection,
Keypair,
Transaction,
SystemProgram,
sendAndConfirmTransaction,
} from "@solana/web3.js";
import {
TOKEN_PROGRAM_ID,
NATIVE_MINT,
getMinimumBalanceForRentExemptAccount,
getAssociatedTokenAddress,
ACCOUNT_SIZE,
createInitializeAccountInstruction,
createTransferInstruction,
createCloseAccountInstruction,
} from "@solana/spl-token";
import bs58 from "bs58";
(async () => {
// connection
const connection = new Connection(clusterApiUrl("devnet"), "confirmed");
// 5YNmS1R9nNSCDzb5a7mMJ1dwK9uHeAAF4CmPEwKgVWr8
const feePayer = Keypair.fromSecretKey(
bs58.decode(
"588FU4PktJWfGfxtzpAAXywSNt74AvtroVzGfKkVN1LwRuvHwKGr851uH8czM5qm4iqLbs1kKoMKtMJG4ATR7Ld2",
),
);
// G2FAbFQPFa5qKXCetoFZQEvF9BVvCKbvUZvodpVidnoY
const alice = Keypair.fromSecretKey(
bs58.decode(
"4NMwxzmYj2uvHuq8xoqhY8RXg63KSVJM1DXkpbmkUY7YQWuoyQgFnnzn6yo3CMnqZasnNPNuAT2TLwQsCaKkUddp",
),
);
// remember to create ATA first
let ata = await getAssociatedTokenAddress(
NATIVE_MINT, // mint
alice.publicKey, // owner
);
let auxAccount = Keypair.generate();
let amount = 1 * 1e9; /* Wrapped SOL's decimals is 9 */
let tx = new Transaction().add(
// create token account
SystemProgram.createAccount({
fromPubkey: alice.publicKey,
newAccountPubkey: auxAccount.publicKey,
space: ACCOUNT_SIZE,
lamports:
(await getMinimumBalanceForRentExemptAccount(connection)) + amount, // rent + amount
programId: TOKEN_PROGRAM_ID,
}),
// init token account
createInitializeAccountInstruction(
auxAccount.publicKey,
NATIVE_MINT,
alice.publicKey,
),
// transfer WSOL
createTransferInstruction(
auxAccount.publicKey,
ata,
alice.publicKey,
amount,
),
// close aux account
createCloseAccountInstruction(
auxAccount.publicKey,
alice.publicKey,
alice.publicKey,
),
);
console.log(
`txhash: ${await sendAndConfirmTransaction(connection, tx, [
feePayer,
auxAccount,
alice,
])}`,
);
})();
