We spent three years building our own operating system from scratch. No Android. No off-the-shelf firmware. Just a microkernel OS written in Rust. KeyOS powers Passport Prime and delivers real process isolation, every app sandboxed, secure message-passing between processes, running on a 500 MHz security processor. It's fully open-source, built on the Xous kernel, and we're opening it up to third-party developers. Every app must be open-source with reproducible builds.

We're thrilled to announce that Passport Prime is officially shipping. 🎊 We set out to build something that didn't exist, that doesn’t fit neatly into any existing categories. Manufactured in the USA, built on open-source principles. New hardware. New OS. New communication layer. New software. What makes Passport Prime different: We built a brand new operating system from scratch. KeyOS uses a modern microkernel design where only the most critical functions run at the core, keeping apps and sensitive data completely segregated. We created QuantumLink, a quantum-resistant Bluetooth protocol that delivers wireless convenience with air-gapped level security. Before shipping, we commissioned a full third-party security audit by Keylabs. The result: zero critical or high-severity vulnerabilities. The full audit and our response are publicly available here: https://foundation.xyz/2025/10/passport-prime-security-au… Passport Prime ships in a premium package: - 3.5" Gorilla Glass touchscreen - CNC-machined aluminum body - 3x NFC KeyCards with Faraday sleeves - USB-C cable. Looking ahead, we're continuing to build KeyOS improvements, a developer SDK, third-party app support, and accessories are all on the roadmap. This is just the beginning. → Learn more: https://foundation.xyz/passport-prime/
