✨ Key Features

hashtag
🔐 1. Triple-Core Chip Architecture, Building the Strongest Hardware Security System

KeyPal 2 is equipped with three independent chips internally, each responsible for different functional domains, isolated yet working together for protection:

  • Main Control Chip MCU (GD32F470): Handles OS operations, interaction logic, and function scheduling.

  • Security Chip SE (THD89): Used to generate and store mnemonics, supports signing, non-readable, non-writable, non-exportable.

  • Bluetooth Chip (nRF52832): Dedicated to BLE communication, preventing the main control layer from leaking any sensitive information.

💡 Encrypted communication channels between chips fully block malicious firmware injection and physical attacks.
