The perfect companion app for your Passport. Secure setup, firmware updates, zen-like Bitcoin wallet. Always open source.
Perfect mobile companion
Quick and easy setup
Envoy offers a guided setup experience for your Passport.
Download and install the latest Passport firmware updates, right from your phone, with the included microSD adapters.
Complete the supply chain validation to ensure your Passport hasn’t been tampered with in-transit.
Learn how to set your PIN, backup your Passport, and automatically pair with Envoy’s wallet – or pair Passport with the software wallet of your choice!
Envoy may be the simplest Bitcoin software wallet on the market.
Envoy’s wallet allows you easily send and receive Bitcoin while your private keys stay on Passport. The only available option is whether to “boost” your transaction (pay a higher fee) – everything else is handled for you automatically.
Are you a sovereign Bitcoiner? Envoy connects to our nodes via Tor by default, but also supports the ability to link your own node instead!
Envoy is open source under GPLv3, and incorporates open source components like BDK and Flutter.
