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…
