Quantum Secure Hardware Wallet
Air-Gapped Cold Storage for Digital Assets
A purely offline cold wallet that never connects to the internet — no USB, WiFi, or Bluetooth interfaces. Physical air-gapping eliminates network-based hacking at the source. Powered by MPC (Multi-Party Computation) technology with sharded private key storage, combined with an open-source architecture and multi-signature protocols, delivering decentralized security management for digital assets.
Six Core Features
Air-Gapped · Open-Source · Easy Recovery · Tamper-Proof · Extensible · Lightweight UX — Comprehensive digital asset protection
Complete Physical Air-Gap
A purely offline cold wallet that is never connected to any network — no USB, WiFi, or Bluetooth interfaces. Physical isolation eliminates network hacking and private key leakage risks at the source.
Fully Open-Source & Auditable
Source code is fully open-sourced on GitHub, open to global user and developer scrutiny. This eliminates any possibility of hidden malicious code or unauthorized private key extraction at the code level.
Multi-Scenario Recovery
If the device is lost or damaged, the wallet program can be regenerated on a new device via the open-source code. Uses the 12-word mnemonic industry standard (BIP39/44), compatible with all wallets following the same standard.
Anti-Tamper Mechanism
Built-in tamper detection that automatically wipes all key data upon detecting physical attacks or firmware vulnerabilities, preventing private key extraction from stolen or compromised devices.
Highly Extensible & Customizable
Continuously updated codebase with open development interfaces. Users and developers can add new cryptocurrency support on top of the source code, leveraging the developer community for feature iteration and customization.
Lightweight & User-Friendly Design
Data transfer is done exclusively via QR codes — no complex device connections required. No device serial numbers, no vendor-side mnemonic recovery — completely eliminating vendor-side asset risks.
Core Technology
Integrating MPC sharding, offline transfer, open-source architecture, and multi-signature protocols into a multi-layered security framework
MPC Multi-Party Computation
Utilizes industry-leading 2-of-3 MPC sharding technology — private keys are split into 3 independent shards stored separately. The complete private key never exists in a single location.
- Assets remain safe even if one shard is lost
- Any 2 of 3 shards can recover the wallet
- Multi-layered protection with absolute control
Offline Data Transfer
Abandons traditional wired/wireless transmission in favor of uni-directional/bi-directional QR code data transfer, where asset verification and synchronization occur only upon user-initiated action.
- Zero network data exchange
- User retains full control over data transfer timing
- Eliminates network eavesdropping and MITM attacks
Open-Source Architecture
Core program built on an open-source ecosystem with no closed-source black-box modules. All encryption, verification, and key generation logic is publicly auditable, eliminating security vulnerabilities and malicious logic at the code level.
- Global developer community review and audit
- Continuous updates and security patches
- Supports secondary development and customization
Advanced Signature & Encryption Protocols
Employs advanced multi-signature protocols combined with Secure Secret Sharing for secure interaction, achieving an optimized cryptographic operation workflow.
- Multi-signature protocols ensure transaction security
- Hardware-to-application secure interaction mechanism
- Supports mainstream blockchain encryption standards
Hardware-Level Tamper Detection
Built-in real-time sensors for physical attacks and firmware vulnerabilities. Upon risk detection, the key self-destruct mechanism is triggered, providing the last line of defense for private key security at the hardware level.
- Real-time physical attack monitoring
- Automatic key destruction on breach
- Prevents cracking after device theft
Industry-Standard Mnemonic Algorithm
Follows the 12-word mnemonic BIP39/44 industry standard, enabling cross-brand, cross-device asset compatibility and recovery, ensuring mnemonic universality and security.
- Compatible with all BIP39/44 standard wallets
- Can recover assets from other brands' cold wallets
- No manual mnemonic transcription required
How It Works
Offline signing via QR code — private keys never touch the internet, achieving true cold storage security
Create Wallet
Generate private keys and store them as shards using MPC technology — split into 3 independent shards
Initiate Transaction
Create a transaction request on the mobile app or desktop, generating unsigned data
QR Code Transfer
Transfer transaction data to the offline hardware wallet via QR code
Offline Signing
The hardware wallet signs the transaction using the private key in a completely offline state
Key Advantage: The private key remains offline throughout the entire process. Signing is completed via one-way QR code transfer, and the signed transaction data is returned to the online device via QR code for broadcasting. Private keys never touch the network, fundamentally eliminating cyberattack risks.
Competitive Advantages
Compared to traditional hardware wallets, the Quantum Secure Wallet offers significant advantages in security, usability, and user control

Frequently Asked Questions
Common questions about the Quantum Secure Hardware Wallet
What if I lose my hardware wallet device?
If the device is lost or damaged, you can regenerate the wallet program on a new device using the open-source code. Assets can be recovered using your 12-word mnemonic phrase or any 2 of the 3 MPC shards, ensuring permanent asset preservation. Anyone who finds the device cannot access your private keys or assets without the password.
How does MPC sharding technology work?
The private key is split into 3 independent shards stored separately — the complete private key never exists in a single location. Even if one shard is lost, your assets remain safe. Recovery requires only any 2 of the 3 shards, providing multi-layered security and absolute control over your assets.
Does open-source mean less secure?
Quite the opposite — open-source provides a higher level of security assurance. The code is publicly reviewed by developers worldwide, and any vulnerability is quickly identified and patched. Compared to closed-source "black box" wallets, an open-source wallet eliminates the possibility of vendors planting backdoors or illegally extracting private keys, giving users true control over their assets.
Is it compatible with other wallet brands?
Yes. The Quantum Secure Hardware Wallet uses the BIP39/44 industry standard. You can recover assets from other cold wallets that follow the same standard, and migrate assets to any other BIP39/44-compatible wallet — enabling full cross-brand and cross-device asset interoperability.
