A More Professional Hardware Wallet Designed for Users.
Product Introduction
KeyPal 2 is a professional-grade hardware wallet product developed by the TokenPocket team. It integrates a high-security dual-chip architecture, a camera module supporting QR code signing, NFC mnemonic backup/recovery, and multiple hardware security mechanisms. Compared with the previous generation KeyPal Plus, KeyPal 2 achieves comprehensive upgrades in security, usability, and interaction, designed specifically for crypto asset holders who pursue more professional and safer solutions.
✨ Key Features
🔐 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.
KeyPal 2 comes with a built-in high-performance camera, supporting QR code interaction protocols (such as EIP-4527), enabling completely offline QR code data transmission and signing:
Supports Bitcoin, Solana, TRON, and EVM multi-chain QR code signing.
Works with the TokenPocket App and plugin wallets supporting the 4527 QR code protocol, ensuring cold-hot isolation.
QR code wallet address display, adapting to mainstream Web3 scenarios (such as DApp, Swap, Bridge, NFT, etc.)
🔄 3. NFC Mnemonic Recovery & Offline Backup
KeyPal 2 features NFC backup/recovery mechanisms, supporting touch-based backup/import of mnemonics via KeyPal Card:
Compatible with BIP39 mnemonic standard.
Quick recovery without manual input.
Mnemonics are processed only within the SE chip, fully isolated throughout the proces.
PIN code encryption.
🔢 4. 15-Key Interaction Design, Supporting Faster and More Accurate Input
Adopts a 5×3 keypad layout, offering a more flexible and secure PIN and mnemonic input experience:
Supports quick input of letters and numbers.
Independent NFC and camera switch buttons.
More efficient and secure interaction input.
📱 5. Multi-Channel Connection Support, Compatible with Mainstream Wallet Ecosystems
KeyPal 2 supports the following connection methods:
QR Code Interaction (AirGap): Supports wallets using EIP-4527 QR code protocols.
Bluetooth (BLE): For pairing with TokenPocket App, iOS/Android devices.
