Trezor Bridge — Comprehensive Guide

What Trezor Bridge was, how it worked, migration to Trezor Suite, troubleshooting, developer hooks, and official resources.

Overview (H2)

Trezor Bridge historically acted as a local communication daemon between a Trezor hardware wallet and browser/web apps or desktop software. It exposed a small webserver or HID interface so apps could securely exchange protobuf messages with the device.

Important: Trezor has deprecated the standalone Trezor Bridge in favor of the integrated approach in Trezor Suite — users are encouraged to uninstall standalone Bridge and use the Suite where possible. :contentReference[oaicite:0]{index=0}

Why the change matters (H3)

Moving Bridge functionality into Trezor Suite creates a single, maintained distribution for device communication, which simplifies updates, reduces compatibility problems with browsers, and lowers the maintenance surface for security patches. Trezor Suite is the actively maintained app for managing devices. :contentReference[oaicite:1]{index=1}

Installation & Uninstall (H3)

Uninstalling standalone Bridge (H4)

If you still have the standalone Bridge installed, follow the official uninstall steps for your OS (macOS: uninstall.pkg; Windows: use the uninstall routine) before switching to the newest Trezor Suite release to avoid conflicts. :contentReference[oaicite:2]{index=2}

Using Trezor Suite instead (H4)

Download the Trezor Suite desktop app (or use the web Suite) and follow the onboarding steps. Suite bundles the communication layer, device drivers, and UI in one package. :contentReference[oaicite:3]{index=3}

Developer notes (H3)

trezord / Bridge daemon (H4)

The open-source trezord / trezord-go repository (Trezor’s communication daemon) remains the reference for how Bridge operated and for advanced integration testing. Developers integrating hardware wallet flows should review the official repo and Trezor Connect resources. :contentReference[oaicite:4]{index=4}

Command-line & advanced tooling (H5)

Advanced users and integrators can also explore trezorctl and other command-line tooling for automation or deep diagnostics. Use the official guides for exact commands and safety notes. :contentReference[oaicite:5]{index=5}

Troubleshooting checklist (H3)

  1. Uninstall any outdated standalone Trezor Bridge packages. :contentReference[oaicite:6]{index=6}
  2. Install or update Trezor Suite to the latest release for your platform. :contentReference[oaicite:7]{index=7}
  3. Check OS permissions for USB/HID access and confirm device appears in system device manager.
  4. Consult Trezor Support for address-poisoning and firmware issues rather than community forks. :contentReference[oaicite:8]{index=8}

Keeping secure & up to date (H3)

Keep firmware, Trezor Suite, and any developer tools up to date. Trezor publishes firmware changelogs and product updates — review the official product updates pages to confirm compatibility and security notices. :contentReference[oaicite:9]{index=9}
