Trezor Bridge — Secure & Smooth Crypto Access®

A concise, practical overview of what Trezor Bridge is, how it fits into the Trezor ecosystem, and secure migration paths.

Executive summary

Trezor Bridge historically provided a local, encrypted communication channel between Trezor hardware wallets and web apps or desktop software. It acted as a trusted intermediate daemon that enabled legacy browsers and standalone apps to securely talk to the device without exposing keys. Over time Trezor has moved functionality into Trezor Suite and WebUSB-friendly flows while maintaining compatibility tooling for developers.:contentReference[oaicite:0]{index=0}

Why Bridge mattered

The Bridge solved two problems: (1) browser security policies prevented direct USB access for pages without WebUSB support, and (2) it offered a controlled, local API that minimized accidental exposure of device interfaces. For many users, Bridge simplified connectivity and reduced friction for on-web interactions.:contentReference[oaicite:1]{index=1}

Current state & migration

Deprecation & migration

Trezor has deprecated the standalone Bridge in favor of integrated solutions and modern browser APIs. Users are encouraged to use Trezor Suite (desktop or web) for the most seamless and secure experience. If you still run a standalone Bridge, follow official uninstall or update instructions to avoid conflicts.:contentReference[oaicite:2]{index=2}

Alternatives for developers

Developers should evaluate Trezor Connect, WebUSB and the trezord/trezord-go tooling (the Bridge daemon written in Go) when crafting integrations — these provide developer-friendly APIs and open-source code you can inspect.:contentReference[oaicite:3]{index=3}

Security & best practices

Always download software only from official domains and verify signatures where possible. Use Trezor Suite for the integrated experience, avoid third-party mirror installers, and confirm that any connection request requires the physical device confirmation (on-device interaction).:contentReference[oaicite:4]{index=4}

Quick checklist

Use official downloads and verify checksums.
Prefer Trezor Suite or trusted WebUSB flows.
Uninstall old standalone Bridge installations if migrating.
Inspect GitHub repos for release notes and signed assets.

Troubleshooting highlights

If Trezor Suite does not detect a device: check USB cable/port, confirm OS permissions, and ensure no legacy Bridge instance conflicts. Use official support resources for step-by-step guides.:contentReference[oaicite:5]{index=5}

Developer tip

For headless systems or custom integrations, consider the trezord-go binary or packaged distributions (Homebrew, AUR) that provide a system daemon with logs you can inspect.:contentReference[oaicite:6]{index=6}
