同步原生 SOL
同步原生 SOL
封装 SOL (WSOL) 是一种代币账户,它将账户中的 lamport 数量作为代币余额进行跟踪。WSOL 使得与 DeFi 协议的集成成为可能,可以将 SOL 作为 SPL 代币进行转账。
SyncNative
指令用于同步封装 SOL (WSOL) 代币账户余额与实际存储在其中的 SOL
(lamport) 数量。当您将原生 SOL 转入 WSOL 代币账户时,代币余额不会自动更新。您必须调用 SyncNative 来反映正确的 WSOL 余额。
Token Program 和 Token Extension Program 具有类似的实现方式以实现相同的功能。
