Trezor Bridge — Install, Status & Guide

What was Trezor Bridge?

A small background helper that enabled web browsers and legacy apps to talk to Trezor hardware over USB.

Trezor Bridge used to be the recommended transport layer for communicating with Trezor hardware devices from browsers and third-party wallets. It operated as a lightweight, cross-platform background application that abstracted USB quirks across operating systems and browsers. When WebUSB support was inconsistent across platforms, Bridge provided a reliable way for websites and wallets to connect to your Trezor device without complex driver installations.

Bridge's design focused on stability: it managed device permissions and maintained a local HTTP-style transport that web pages could call into. For several years it helped make web-based wallet experiences usable for both Trezor One and Model T users. But as browsers improved native USB support and Trezor consolidated connectivity into the official Trezor Suite, the role of the standalone Bridge changed.

Current status — short

Standalone Trezor Bridge is no longer the recommended path. Modern users should rely on Trezor Suite (desktop or web) and native browser WebUSB flows. Bridge is effectively deprecated for the majority of users and keeping an old Bridge installation can cause conflicts with newer Suite transports.

When Bridge might still be seen

Bridge can appear in three contexts today: legacy systems that haven't adopted modern WebUSB, very old device firmware that required Bridge for certain flows, or niche third-party wallets that haven't migrated away from Bridge. Even in those rare cases, the better approach is to upgrade the host environment or use Suite where possible.

How to uninstall Bridge (if installed)

If you still have a standalone Bridge installation, follow official OS-specific steps to remove it — keeping it can cause conflicts with modern Suite installations.

Below are the typical steps; exact names and flows can vary by OS version.

macOS (general): 1. Open Finder → Applications 2. Find "TREZOR Bridge" or "Trezor Bridge" 3. Run the provided uninstall script or drag the app to Trash 4. Reboot if necessary Windows (general): 1. Settings → Apps → Installed apps 2. Find "Trezor Bridge" → Uninstall 3. Follow the on-screen uninstall wizard Linux (example): - If installed via package: sudo apt remove trezor-bridge (or relevant package name) - If used a standalone binary, remove installed files from /usr/local/bin or /opt as appropriate

Always consult the official documentation for exact commands—this page provides a practical summary and troubleshooting tips, not an exhaustive OS guide.

Troubleshooting & safe alternatives

If a site fails to connect to your Trezor: do not immediately install random Bridge binaries. Instead:

Try the official Trezor Suite (desktop or web). Suite contains the maintained transport layers and modern connectivity logic.
Use a recent browser (Chrome, Edge, Brave) that supports WebUSB and ensure browser flags or permissions are enabled for WebUSB on the relevant origin.
Test on another machine with current OS/browser to see if the issue persists—this isolates host problems.

Security tip: never download Bridge from an untrusted mirror, or run an installer presented by an unfamiliar site. If you are asked for your recovery seed at any point, stop immediately—Trezor support will never ask for your seed.

Quick fixes

Restart the browser and reconnect the device.
Try a different USB cable or port (prefer a data-capable cable).
Use the official Suite's web option: open trezor.io/start → Continue in browser.

When Bridge is the only option

In extremely legacy setups where nothing else works, obtain the Bridge installer only from the official Trezor documentation links and follow strict verification steps. Prefer upgrading OS/browser where possible instead of keeping outdated tooling.
