What Is Wrapped SOL?
Wrapped SOL (WSOL) is SOL held in a token account for the Token Program's native mint. The native mint is the mint address the Token Program uses for token accounts that wrap SOL. The native mint enables SOL to be used through the Token Program's instructions.
| Program | Native mint address |
|---|---|
| Token Program | So11111111111111111111111111111111111111112 |
| Token Extension Program | 9pan9bMn5HatX4EJdBwg9VgCa7Uz5HL8N1m5D3NdXejP |
A wrapped SOL token account stores SOL in the account's lamports field, but
tracks the SOL held in the wrapped SOL token account as a token balance through
the token account amount field. If you transfer SOL into a wrapped SOL
token account, the lamport balance increases immediately, but the token
amount field does not change until you call the Token Program's
SyncNative instruction.
How to Sync Native SOL
Use the Token Program's SyncNative instruction after transferring SOL into
a wrapped SOL token account. The SyncNative instruction updates the token
account amount field to match the lamports held in the account above its
rent-exempt reserve.

The Kit examples below show the recommended approach using @solana/kit.
Legacy examples using @solana/web3.js are included for reference.
