Foundation designs and manufactures Bitcoin-centric tools that empower you to reclaim your sovereignty.

We aimed to build a different kind of hardware company with an emphasis on open source and local manufacturing.

This starts with Passport and Envoy – but we are just getting started!

About US >

Thoughtful Design


Passport is designed to be simple and elegant with a distinctive industrial design.

Crafted from premium materials, Passport includes a hardened glass display, magnetic rear cover, and copper-plated zinc-alloy substructure.

Intuitive Interface

Passport’s larger screen and familiar menus offer a refreshingly simple user experience. You already know how to use Passport.

The physical keypad offers quick text entry, and QR codes allow for secure, airgapped Bitcoin transactions.

Ideal Mobile Companion

Envoy, our new mobile app, perfectly pairs with Passport for a best-in-class onboarding experience.

Setup Passport, install the latest firmware, and use a simple and private Bitcoin wallet – no need to touch your computer.

Unparalleled Software


Passport’s beautiful and intuitive user interface makes you feel right at home. We overhauled the UI to take advantage of Passport’s color screen, with easier left-to-right navigation.

Passport natively uses PSBTs (partially signed Bitcoin transactions), a universal transaction format, to ensure openness and compatibility.


Envoy is a cross-platform mobile app for iOS and Android. Designed to be a mobile companion to your Passport, Envoy walks you through onboarding, supply chain verification, and firmware updates. Support resources and important notifications are available in-app.

Envoy also offers a simple Bitcoin software wallet that provides a zen-like experience. Envoy’s wallet is perfect for new Bitcoiners.

Broad Compatibility

For power users looking to connect Passport with the software wallet of your choice – you’re in luck! Passport is compatible with the most popular software wallets on mobile and desktop, via microSD and QR codes.

New integrations are being rolled out regularly. Let us know if you’d like a Passport integration with your favorite wallet.

Transparent Security

Truly Open Source

Foundation believes that the best security is through openness, not secrecy. Passport and Envoy are proudly open source – all software, electrical, and mechanical components are open and auditable. There is no hidden code or restricted information.

Passport’s hardware is open sourced via CERN’s Open Hardware License and our firmware via GPL. This means that Passport meets the legal definition of open source hardware.

Likewise, our Envoy mobile app is open source under GPLv3, and incorporates open source components like Bitcoin Development Kit (BDK) and Flutter.

Airgapped Security

Passport has no USB ports or wireless communications. To transact, simply scan a QR code or insert a microSD card. This more robust security model ensures that you know exactly what information is being received by Passport – and makes it significantly more difficult for potential attackers to communicate with the device.

Passport connects with Envoy in seconds using QR codes to transact securely and privately.


Passport uses a secure element chip to protect your keys from physical attacks.

Trustable Entropy

Passport uses an open source true random number generator to generate secure keys.

Supply Chain

Ensure your Passport was not tampered with during shipping with our validation process.

With TOR

Envoy connects to the Internet through Tor, offering maximum privacy.

assembled in the USA

In a Bitcoin world, we need more trustable hardware. We need components from reputable suppliers and tight control over supply chains. We need to be physically present on the factory floor. We need open source, auditable designs. And we need to build our hardware in jurisdictions which stand for basic human rights and freedoms.

This is why Foundation assembles Passport in the USA.
