Solana’s token extensions and their role in PYUSD development

Solana 的代幣擴展及其在 PYUSD 開發中的作用

Token extensions (TEs) on the Solana blockchain are powerful tools that expand the functionality of the Solana Program Library (SPL) Token Program, the standard for creating tokens.

Solana 區塊鏈上的代幣擴展 (TE) 是功能強大的工具，可擴展 Solana 程式庫 (SPL) 代幣計劃（創建代幣的標準）的功能。

TEs are composable modules that can be applied to a token to offer specific features or functionalities. Simple metadata additions to intricate compliance and governance systems are examples of these enhancements.

TE 是可組合模組，可應用於代幣以提供特定特性或功能。這些增強功能的範例包括在複雜的合規性和治理系統中添加簡單的元資料。

The specific TEs PYUSD utilizes on Solana are:

PYUSD 在 Solana 上使用的具體 TE 是：

These token extensions enable the following benefits for PYUSD:

這些代幣擴展為 PYUSD 帶來了以下好處：

Enhanced functionality

增強功能

TEs allow PYUSD transactions to be confidential for users while remaining transparent for regulators, striking a balance between confidentiality and compliance.

TE 允許 PYUSD 交易對用戶保密，同時對監管機構保持透明，在保密性和合規性之間取得平衡。
