Keycard Launches Pre-Sale for Modular Hardware Wallet Shell

Keycard, a hardware wallet company supported by the Status team, has launched the pre-sale for Shell, a revolutionary hardware wallet designed to be the most open and modular to date. The pre-sale, which began on April 23rd, 2025, in Zug, Switzerland, offers early supporters the opportunity to pre-order Shell bundled with two Keycards at a discounted rate. This bundle also provides access to exclusive pre-launch rewards, making it an attractive option for those looking to secure their cryptocurrency assets with cutting-edge technology.

Shell stands out in the hardware wallet market due to its open and modular design. This design allows users to customize their wallet according to their specific needs, providing a level of flexibility that is unmatched by other hardware wallets. The modular nature of Shell means that users can easily upgrade or replace components, ensuring that their wallet remains secure and up-to-date with the latest technology.

The pre-sale launch of Shell is a significant milestone for Keycard, as it marks the company's commitment to innovation and user empowerment. By offering a hardware wallet that is both open and modular, Keycard is providing users with a tool that can adapt to their changing needs, rather than being limited by the constraints of traditional hardware wallets. This approach not only enhances the security of users' cryptocurrency assets but also ensures that they have a wallet that can grow and evolve with them.

The pre-sale launch of Shell also highlights the growing demand for secure and customizable hardware wallets in the cryptocurrency market. As the value of cryptocurrencies continues to rise, so does the need for secure storage solutions. Shell's open and modular design addresses this need by providing users with a wallet that can be tailored to their specific requirements, ensuring that their assets are protected against potential threats.

In addition to its open and modular design, Shell also offers a range of features that make it an attractive option for cryptocurrency users. These features include support for multiple cryptocurrencies, a user-friendly interface, and advanced security measures. By combining these features with its open and modular design, Shell provides users with a comprehensive solution for securing their cryptocurrency assets.

Shell is powered by Keycard, an EAL6+ certified, open-source smart card that signs transactions and stores keys internally—ensuring they never leave secure hardware. Moreover, Keycard firmware is not upgradable by design, providing long-term assurance that the device behavior will never change post-manufacture. This ensures that users have complete control over their digital assets, with no risk of unauthorized access or tampering.

One of the key features of Shell is its support for multiple stealth smart cards, allowing users to store multiple seed phrases or use backup cards safely. Even if one card is lost, others remain secure, providing an additional layer of protection for users' assets. Additionally, Shell supports air-gapped operation, enabling users to sign transactions safely using its integrated camera and QR-code interface, without the need for USB, Bluetooth, or Wi-Fi connections.

Shell also includes duress PIN support, which defends against physical coercion with a second PIN. This feature ensures that users' assets remain secure even in the event of physical threats. Furthermore, Shell is compatible with major EVM and Bitcoin wallets, including MetaMask, Rabby, BackPack, imToken, UniSat, and BlueWallet, using QR-based signing. This cross-wallet compatibility makes Shell a versatile option for users who manage multiple cryptocurrencies.

The future-proof design of Shell includes an easily replaceable battery, extending the device life, and upgradable Keycards, meaning Shell adapts as cryptographic standards evolve. This ensures that users' wallets remain secure and up-to-date with the latest technology, providing long-term value and peace of mind.

The pre-sale launch of Shell is a testament to Keycard's dedication to innovation and user empowerment. By offering a hardware wallet that is both open and modular, Keycard is providing users with a tool that can adapt to their changing needs, ensuring that their assets are protected against potential threats. As the cryptocurrency market continues to evolve, it is clear that secure and customizable hardware wallets will play an increasingly important role in protecting users' assets. With its open and modular design, Shell is well-positioned to meet this demand and provide users with a secure and adaptable solution for their cryptocurrency needs.
