Keycard Launches Pre-Sale For Shell: The Most Open, Modular Hardware Wallet To Date | HackerNoon

Zug, Switzerland, April 23rd, 2025/Chainwire/–Keycard, a hardware wallet company backed by the Status team, is proud to announce the pre-sale launch of Shell, a revolutionary, fully open-source hardware wallet.

Designed with modularity, transparency, and uncompromising security at its core, Shell enables users to seamlessly manage multiple wallets through interchangeable smart cards—called Keycards—for enhanced convenience and safety.

Early supporters can now pre-order Shell bundled with two Keycards at a discounted rate and gain access to exclusive pre-launch rewards ahead of its global release in October 2025.

Redefining the Hardware Wallet Architecture

Current hardware wallets often market themselves as transparent and open source, yet many lack true transparency in their designs—relying on closed-source components, exportable keys, or upgradeable secure elements that weaken user trust. Shell sets a new benchmark in wallet architecture.

“Hardware wallets need a complete rethink,” says Guy-Louis Grau, Project Lead at Keycard. “Users rarely realize that most hardware wallets allow private keys to be exported outside secure elements or rely on upgradable secure elements—both of which compromise the integrity and transparency of the device.”

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.

Shell: Built for Transparency, Security, and Control

Shell is about more than security, it’s designed for those who demand verifiable control over their hardware and digital assets:

• 100% Open Source: Every layer—from chip software to hardware layout and 3D-printable casing—is verifiable and customizable, exceeding the transparency of leading competitors.
• Multiple Stealth Smart Cards: Users can store multiple seed phrases, or use backup cards safely—even if one card is lost, others remain secure.
• Air-Gapped Operation: Users can sign transactions safely using Shell’s integrated camera and QR-code interface—no USB, Bluetooth, or Wi-Fi connection to devices required.
• Duress PIN Support: Defends against physical coercion with a second PIN.
• Cross-Wallet Compatibility: Works seamlessly with major EVM and Bitcoin wallets like MetaMask, Rabby, BackPack,imToken, UniSat, BlueWallet and more using QR-based signing.
• Future-Proof Design: Easily replaceable battery extends the device life, and upgradable Keycards mean Shell adapts as cryptographic standards evolve—unlike most competitors.
