# 11.1 Data Protection & Encryption

SyFu is designed with **the highest priority on safeguarding users’ payment data and digital assets**.\
By leveraging encryption and decentralized technologies, we maintain strict security standards at all times.

***

#### **Security Architecture**

* **MPC Wallet**
  * Private keys are split and distributed; never exposed, even during recovery.
* **Spending Wallet**
  * A smart-account wallet separated for in-game use.
  * Optimized for speed and safety via off-chain conversion.
* **Data Encryption**
  * Only minimal data is collected (merchant name, amount, date/time).
  * Always encrypted; never used externally without consent.
