What is Trezor Bridge?

Trezor Bridge was a small background application that allowed desktop web browsers to communicate with Trezor hardware wallets over USB ports. Historically it filled gaps in browser USB support and provided a stable bridge between the device and web-based wallet interfaces.

Status (short)

As of 2025, Trezor has deprecated the standalone Trezor Bridge. Users are encouraged to rely on Trezor Suite (desktop/web) and modern browser WebUSB support for device connectivity. If you still have a standalone Bridge installation, official guidance recommends uninstalling it to avoid compatibility issues with newer releases.

When Bridge was used

Bridge was commonly required for older browsers or older operating systems where direct WebUSB communication was unreliable. It ran in the background, allowed persistent connections, and avoided repeated permission prompts in some workflows. Many third-party wallet integrations historically relied on Bridge to provide consistent USB communication.

Why it was deprecated

Modern browsers (Chrome, Edge, Brave, and others) have improved WebUSB support, and the Trezor Suite desktop app bundles connection layers that cover most use cases. Consolidating connectivity into Suite and WebUSB reduces duplicated tooling, simplifies updates, and avoids conflicts caused by multiple bridge-like components running on the same machine.

Should you install or uninstall Bridge?

Short answer: mostly no. For most users, you should use Trezor Suite (desktop or web) and only install software recommended by the official site. If you currently have standalone Trezor Bridge installed, follow the official uninstall steps — leaving it installed may interfere with future Suite releases.

How to connect your Trezor today

  1. Open trezor.io/start and download Trezor Suite for your OS, or choose "Continue in browser".
  2. Use a modern, updated browser if you opt for the web Suite (Chrome, Edge, Brave recommended).
  3. Connect your Trezor via USB, follow on-device prompts, and approve actions on the device screen.

Troubleshooting & legacy cases

If you have an old OS or browser and cannot use WebUSB or the Suite, Bridge installers previously existed for Windows/macOS/Linux. However, because the standalone Bridge is deprecated by Trezor, avoid installing unofficial copies. If you truly need legacy support, check the official Trezor guides or community forum for sanctioned instructions — and be cautious about security risks.

Security considerations

Only download connectivity tools from trezor.io or official Trezor channels. Avoid third‑party mirror sites and packaged copies unless they are explicitly linked from the official documentation. If a site or a popup asks for your recovery seed, stop immediately — Trezor support will never request your seed phrase.

Quick command: how to remove Bridge (example)

Official uninstall instructions vary by OS; here are short pointers (see the official article for exact steps):

macOS: Finder → Applications → Utilities → TREZOR Bridge → run uninstall.pkg

Windows: Use Add/Remove Programs → select TREZOR Bridge → Uninstall

Linux: use package manager or remove the installed package (varies by distro)
