Wrapped SOL

Q: What is the WSOL mint address?

So11111111111111111111111111111111111111112 on all clusters.

Q: How do I unwrap?

spl-token unwrap or close/drain WSOL ATA per SDK patterns.

Wrapped SOL (wSOL) is native SOL held inside an SPL token account. DeFi programs expect SPL token CPIs, so SOL is temporarily wrapped, used, then unwrapped back to native lamports.

Recipe

spl-token wrap 1.5
spl-token unwrap <WSOL_TOKEN_ACCOUNT>

use anchor_lang::system_program;
use anchor_spl::token::{self, sync_native, TokenAccount};
 
// Deposit lamports into WSOL ATA, then sync_native

When to reach for this:

Paying or swapping on AMMs that only accept SPL tokens
Pool deposits where one side is SOL
Programs that unify SOL and SPL in one transfer code path
Closing WSOL ATA to reclaim SOL after DeFi interaction

Working Example

solana balance
spl-token address --token So11111111111111111111111111111111111111112
spl-token wrap 0.5
spl-token balance So11111111111111111111111111111111111111112
spl-token unwrap <WSOL_ATA_ADDRESS>
solana balance

// Many DEX SDKs auto-wrap SOL; manual flows use syncNative instruction after lamport transfer

What this demonstrates:

WSOL mint is the well-known native mint pubkey
Lamports transfer to token account + sync_native updates SPL balance
Unwrap closes or drains WSOL ATA back to native SOL wallet

Deep Dive

How It Works

Native mint address: So11111111111111111111111111111111111111112
Token account can hold lamports directly; sync_native reconciles SPL amount field
9 decimals - matches SOL lamport precision
AMMs often create WSOL ATA, wrap, swap, unwrap in one transaction

Wrap vs Native SOL

Form	Account type	Used by
Native SOL	System-owned wallet	Transfers, fees, staking
wSOL	SPL token account (same mint)	AMMs, unified token vaults

Rust Notes

// Close WSOL account to unwrap - returns lamports to destination
use anchor_spl::token::CloseAccount;
// Ensure amount is 0 or use withdraw pattern per your SDK

Gotchas

Forgetting sync_native - lamports sit in account but SPL amount is 0. Fix: always sync_native after lamport deposit.
Using wrong mint - only native mint is WSOL. Fix: compare to native_mint::ID.
Leaving dust in WSOL ATA - locked lamports until unwrapped. Fix: unwrap or close after DeFi flow.
Paying rent twice - WSOL ATA needs rent-exempt funding. Fix: reuse persistent WSOL ATA per wallet.
Assuming programs accept native SOL - many only CPI SPL transfer. Fix: wrap or use program's native deposit instruction.

Alternatives

FAQs

What is wrapped SOL?

SOL deposited into an SPL token account for the native mint, making it behave like any SPL token in programs.

What is the WSOL mint address?

So11111111111111111111111111111111111111112 on all clusters.

Why wrap SOL at all?

SPL Token program CPIs cannot move native lamports from wallets without wrapping pattern.

How many decimals does WSOL use?

9, matching lamports per SOL.

Does wrap reduce wallet SOL balance?

Yes. Lamports move into WSOL token account (plus fees).

What does sync_native do?

Updates token account amount field to match lamports held by the account.

Can I send WSOL like any SPL token?

Yes. Standard transfer between WSOL token accounts.

How do I unwrap?

spl-token unwrap or close/drain WSOL ATA per SDK patterns.

Do Jupiter swaps auto-wrap?

Yes for most SOL-input swaps - SDK handles wrap/unwrap in transaction.

Is WSOL mint authority revocable?

Native mint is protocol-defined - not a typical launch mint.

Can programs hold WSOL?

Yes in PDA-owned WSOL ATAs with proper signer seeds on transfer.

WSOL on Token-2022?

WSOL uses classic native mint on Token program, not Token-2022.
