Trézor Bridge® | Secure Hardware Wallet Connection

Trézor Bridge® provides a secure and simple way to connect your Trézor hardware wallet to web applications and desktop interfaces while keeping private keys offline.

What is Trézor Bridge®?

Trézor Bridge® is a small, local-bridge application that runs on your computer and facilitates encrypted communication between Trézor hardware devices and browser-based or desktop wallet software. Trézor Bridge® never transmits private keys to the internet — it only forwards signed requests between your device and the requesting app.

Why use Trézor Bridge®?

Using Trézor Bridge® isolates signing operations on the hardware device, ensuring that sensitive seed material remains offline. Trézor Bridge® reduces attack surface by limiting direct USB access to authorized local applications and supporting secure firmware checks.

Installing & configuring Trézor Bridge®

Follow these steps to install and run Trézor Bridge®:

Download the official Trézor Bridge® installer for your OS and run the package as Administrator / with elevated permissions.
After installation, start Trézor Bridge® (it runs in the background and listens on a local port).
Open your preferred wallet application and choose the Trézor connection option; the app will detect Trézor Bridge® and request device authorization.
Authorize the connection on your physical Trézor device screen when prompted.

Tip: If you need to troubleshoot, restart Trézor Bridge® and reconnect the device. Use Ctrl/⌘ + R where applicable to refresh the wallet UI.

Security considerations for Trézor Bridge®

Trézor Bridge® is designed to minimize risk, but follow these best practices to improve overall safety:

Always install Trézor Bridge® from official sources and verify signatures when available.
Keep your Trézor firmware up to date and verify firmware authenticity on the device during updates.
