In the high-stakes world of digital asset management, speed and security are often at odds. For the Inabit ecosystem, the mobile app was not merely a companion—it was designed to be the definitive security gatekeeper. My objective was to architect a mobile-first governance experience that empowered administrators and account owners to authorize critical transactions, manage wallet access, and enforce complex organizational policies on the go. As the design lead, I focused on the intersection of Role-Based Access Control (RBAC) and mobile usability. This involved translating multi-signature (Multi-sig) workflows—which are traditionally cumbersome—into a streamlined, high-trust mobile interface. By prioritizing real-time clarity and biometrically-secured approval flows, we created a tool that allows SMB leaders to maintain total control over their treasury without being tethered to a desktop.
