Синхронізація нативного SOL
Синхронізація нативного SOL
Wrapped SOL (WSOL) — це токен-акаунт, який відстежує кількість лампортів в акаунті як баланс токена. WSOL забезпечує інтеграцію з DeFi-протоколами для передачі SOL як SPL-токена.
Інструкція
SyncNative
синхронізує баланс токен-акаунта wrapped SOL (WSOL) з фактичним SOL
(лампортами), що зберігаються в ньому. Коли ви переказуєте нативний SOL на
токен-акаунт WSOL, баланс токена не оновлюється автоматично. Ви повинні
викликати SyncNative, щоб відобразити правильний баланс WSOL.
Token Program та Token Extension Program мають подібні реалізації для досягнення однакової функціональності.
