Key Features

🔐 1. Dual-chip architecture with hardware-software collaborative protection

• Main control chip uses NXP high-performance MCU, supporting hardware encryption, system integrity check, and anti-malware firmware injection;

• Built-in financial-grade SE security chip dedicated to private key generation, storage, and encryption, with a true random number generator and physical anti-tamper capability;

• Mnemonics and private keys never leave the chip, effectively preventing physical extraction and brute-force attacks.

🆔 2. Device-level anti-counterfeiting certification

• Each KeyPal Plus has a unique hardware identity certificate issued under the official root CA, generated and programmed in a highly secure offline environment;

• Unique serial number + secure chip packaging;

• Anti-counterfeiting can be verified online via official tools to ensure reliability and prevent counterfeit devices from threatening user funds.

🔒 3. PIN code protection mechanism

• Users must set a PIN code for wallet unlocking and authorizing critical operations;

• 9 consecutive incorrect attempts will trigger device initialization, automatically erasing all data to prevent unauthorized access in case of loss or theft.

🧊 4. Fully offline generation and recovery

• Compliant with BIP32 / BIP39 / BIP44 protocols;

• Wallet creation and mnemonic recovery are fully offline to ensure no interception or leakage;

• Compatible with any wallet mnemonics supporting the same standards.

🔗 5. De-sensitized communication channels

• Supports both USB (HID mode) and Bluetooth 4.1 communication;

• No sensitive data is transmitted via Bluetooth, eliminating risks of intercepted private keys, mnemonics, or signatures.

👀 6. Secure visualized operations

• 2.0-inch full-color LCD displays transaction details such as addresses, amounts, and gas fees in real-time;

• Ensures "What You See Is What You Sign," preventing phishing and man-in-the-middle attacks.

🔄 7. Firmware upgrade mechanism

• Firmware can be upgraded with official TokenPocket tools after device identity verification;

• Unlocks additional coin support and updated standards, ensuring continuous adaptation to the blockchain ecosystem.
