Open Application

Foundation Devices, Inc. is a Bitcoin and self-custody hardware company that designs, manufactures, and sells open-source hardware wallets and companion software. Its products include Passport Core and Passport Prime hardware devices, the Envoy mobile wallet app, and KeyOS, a Rust-microkernel operating system that powers sandboxed apps on Passport Prime with features such as QuantumLink encrypted Bluetooth, secure element protection, NFC keycards, and encrypted backups. The company positions Passport Prime as 'Human Authority Hardware,' extending beyond Bitcoin custody into 2FA, security keys, encrypted file storage, and general approval/signing workflows for both individual users and enterprises. Foundation emphasizes open-source hardware and firmware, independent third-party security audits (e.g., by Keylabs), reproducible builds, and a responsible disclosure program. It maintains developer documentation and an SDK for building KeyOS apps, an active blog with product updates and privacy/freedom-tech commentary, and a community support forum. The company has raised seed and pre-seed funding rounds and, per its blog, a recent $6.4M raise tied to the Passport Prime launch, and manufactures its hardware in the USA at an ITAR facility.
