# Cold Wallet Storage

Tychi Wallet offers a secure cold storage solution designed for users who prioritize maximum asset protection. This system ensures that private keys are never exposed to online threats.

### 🔐 Key Security Features

* **True Offline Key Storage**\
  Private keys are stored entirely offline, never touching internet-connected systems—qualifying Tychi’s cold wallet as true cold storage.
* **Three-Factor Authentication (3FA)**\
  Access requires three layers of security:
  1. Password/PIN
  2. Biometric verification (fingerprint or facial recognition)
  3. Hardware token authentication
* **Tamper-Resistant Architecture**\
  The infrastructure is designed to prevent unauthorized access attempts through physical or digital means. All access attempts are logged and monitored.
* **Tier-Based Access Control**\
  Cold wallet features are reserved for users with verified credentials, and in some cases, active subscriptions with appropriate tier status.

### 💽 USB Drive or External Device

* Private keys are exported and stored on a secure, encrypted **USB drive**.
* Can be **decrypted only through the Tychi Wallet app** using proprietary decryption logic.
* Built-in **tamper-proof hardware** alerts users if unauthorized access attempts are detected.
