### **Overview**

The Cardware BTC is a Bitcoin Only hardware wallet specifically designed for Bitcoin maxis seeking a secure and offline solution for managing their digital assets. The device is powered via USB-C with only power and ground connections active—all data lines are disconnected and visibly shown on the circuit board through our transparent casing. This design ensures that private keys remain isolated from the internet and eliminates risks associated with data transmission through cables. The wallet aligns with the stringent security standards valued by Bitcoin maximalists, providing a robust and verifiable solution for secure Bitcoin storage.

### **Device Description:**

Cardware (BTC) is an affordable and secure hardware wallet that offers a truly air-gapped and offline solution for managing your Bitcoin ($BTC) assets. Powered via USB-C with no data rails active—only the power and ground connections are utilised—the device ensures that no data can be transmitted through the USB-C port, maintaining a secure and isolated environment. Utilising Cardware's QR code connection method, you can pair the device in under two seconds and interact with your assets instantly via our Web App, all while ensuring that your private keys are never exposed to the internet. The wallet generates high-entropy private keys through Video Streaming or Dice Rolls upon setup, enhancing the security and uniqueness of your keys. With the absence of data connections (purely power), the device provides easy portability and quick access without the risks associated with external connections, unauthorised code modifications, or malicious actors. Designed for individual or institutional users, Cardware Wallet BTC seamlessly integrates with our watch-only Web Based wallet and is accessible from any device with a browser, offering secure and convenient BTC management. With a strong focus on Web Integration, Cardware Wallet's B2B arm allows for simple and easy integration via NPM packages.&#x20;
