How to manage wrapped SOL
you can use thisWrapped 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
let tx = new Transaction().add(
// trasnfer SOL
SystemProgram.transfer({
fromPubkey: alice.publicKey,
toPubkey: ata,
lamports: amount,
}),
// sync wrapped SOL balance
createSyncNativeInstruction(ata)
);
2. By Token Transfer
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
)
);
