Cardware Wallet is a 100% air-gapped & offline hardware wallet designed to provide secure and affordable solutions for managing digital assets. Powered via USB-C with only power and ground connections active—visibly verified through its transparent circuit board—the device ensures that no data connections are possible. This design keeps private keys completely isolated from the internet and eliminates risks associated with data transmission, offering a robust security solution for cryptocurrency holders.
Cardware Wallet addresses the modern demand for verifiable security in digital asset management by operating entirely offline, ensuring that private keys never connect to external networks. Its USB-C port is limited to power and ground only—no data lines—and this transparent design lets users confirm there are no hidden connections. An EAL6+ certified secure element chip, Web Wallet (Watch-Only) accessible, and hardware-level read/write protection combine to guard against physical tampering, unauthorised access, and firmware-based exploits.
Beyond its robust security, Cardware is also designed for practicality: it integrates seamlessly with web-based platforms, offering an NPM package and watch-only wallet features that simplify usage and development. This fusion of powerful security and straightforward web compatibility means users can enjoy convenient monitoring and transaction management without compromising on safety. Finally, Cardware’s “Don’t Trust, Verify” philosophy is embodied in its transparent casing, allowing anyone to visually inspect internal components and gain genuine confidence in the device’s integrity. Together, these features make Cardware Wallet an essential solution for anyone looking to secure their digital assets against modern threats while maintaining user-friendly functionality.
100% Air-Gapped and Offline Operation
Feature: Operates without internet, Bluetooth, or Wi-Fi connectivity.
Benefit: Prevents exposure to online threats and remote hacking attempts, keeping private keys secure.
USB-C Powered with Transparent Design
Feature: Powered via USB-C with only power and ground connections; all data lines are disconnected and visibly so.
Benefit: Users can verify that no data can be transmitted through the USB-C connection, eliminating risks associated with malicious cables or data transfer.
High Entropy Key Generation
Feature: Cardware Wallet uses hashed video streams or repeated dice rolls (D20 or D6) to generate highly unpredictable private keys. Each pixel from the video feed or each dice roll outcome is processed by a cryptographic hash function, ensuring a vast and truly random pool of entropy.
Benefit: By capturing real-world randomness, the private keys become practically impossible to predict or replicate. This robust entropy source sharply reduces the risk of brute-force attacks and guarantees that your keys remain uniquely secure.
Secure Element Chip
Feature: Utilises an EAL6+ certified secure element chip for key storage.
Benefit: Provides a tamper-resistant environment for cryptographic operations, protecting against advanced physical and logical attacks.
Read/Write Protection
Feature: Microchip include read/write protection mechanisms.
Benefit: Prevents unauthorised access or modification of the device's firmware and sensitive data, maintaining data integrity.
Non-Upgradable Firmware
Feature: Firmware is fixed and non-upgradable.
Benefit: Eliminates risks associated with firmware updates, such as introducing vulnerabilities, ensuring the device's code remains secure and immutable.
Web Wallet Integration
Feature: Integrates with web-based platforms through QR codes and our NPM Package, providing easy and accessible functionality for any developers.
Benefit: Allows Web2 and Web3 based businesses to integrate self custody & hardware wallet solutions using NPM packages with little integration.
Advanced Security Features
Feature: Supports multisignature wallets, hierarchical deterministic (HD) wallets, and secure transaction signing via QR codes.
Benefit: Enhances security and flexibility in managing digital assets, allowing for distributed signing authority and organised key management.
By focusing on offline operation, transparent hardware design, and robust security protocols, Cardware Wallet offers a secure and user-friendly solution for managing digital assets, addressing the critical need for trustworthy hardware wallets in the cryptocurrency space.
