Welcome To Cardware Wallet
What is Cardware Wallet?
Cardware Wallet is an 100% air-gapped, 100% 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.
Why Cardware Wallet is Important
In the realm of digital assets, security is paramount. Cardware Wallet addresses this by maintaining an entirely offline environment for managing cryptocurrencies. By powering the device via USB-C with only power and ground connected, and all data lines disconnected and visible to the user, it eliminates the risk of malicious attacks through data cables. The transparent design allows users to verify the absence of active data connections, fostering trust in the device's security. Additionally, the use of an EAL6+ certified secure element chip and non-upgradable firmware provides strong protection against unauthorised access and firmware-based attacks, ensuring the integrity of private keys and transactions. Our microchips come with read/write protection, preventing any unauthorised rewrites of the device's code by malicious actors. Moreover, our ethos of "Don't Trust, Verify" is reflected in the transparent design of our hardware wallets, allowing users to see exactly what is inside their device, adding a layer of openness and trust.
Features and Benefits
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: SHA256 is predicated on the entropic properties of 256 bits. There are 8 bits to a byte which leaves us with 64 bytes providing 256 bits of entropy. With Cardware your private key is generated using a picture you take of the world around you, providing 15534 bytes or 124272 bits of real world randomness which is used to securely generate your seed phrase.
Benefit: Ensures each private key is unique and highly secure, reducing the likelihood of key duplication or prediction.
Secure Element Chip
Feature: Utilizes 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 and write protection mechanisms.
Benefit: Prevents unauthorized 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 accesible functionality for any developers. This further allows watch only wallets.
Benefit: Allows users to monitor transaction history and balances securely, with private keys remaining offline on the hardware device. Transactions can only be executed using the physical device.
Advanced Security Features
