KeyPal 2 Main Features Overview
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.
📸 2. EIP-4527 QR Code Signing, Supporting Multi-Chain Offline Signature Scenarios
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.
USB Connection: For firmware upgrades.
Compatible with:
TokenPocket App (Android / iOS / Chrome Extension).
MetaMask (via QR protocol).
All wallets or Web applications that meet signature standards.
🌐 6. Comprehensive Coin and Network Upgrade Support
Supports BTC, ETH, TRON, BNB, SOL, DOGE, EVM ecosystem and other mainstream blockchains and tokens.
Firmware upgrades continuously add support for new networks and assets.
🔒 7. Factory Anti-Counterfeiting and Identity Verification Mechanism
Each KeyPal 2 device contains a unique certificate issued by the official authority, recorded in the SE chip.
With the TokenPocket App, users can perform online authenticity checks to prevent counterfeit devices from non-official channels.
