Trezor Bridge

Secure & Smooth Crypto Access — Official connectivity layer for Trezor devices
A lightweight, secure bridge between your Trezor hardware and desktop/web apps

What is Trezor Bridge?

Trezor Bridge is a small, trusted application that facilitates communication between your Trezor hardware wallet and desktop or browser-based wallets and services. It runs locally on your computer and allows web interfaces (like Trezor Suite web) or other compatible applications to talk with the device over a secure channel. The Bridge ensures compatibility across operating systems and browsers while keeping your seed and private keys on-device — where they belong.

Why the Bridge matters

Modern browsers restrict direct USB access for security reasons. Trezor Bridge provides a controlled, auditable pathway to enable device interactions while minimizing attack surface. It avoids exposing low-level USB APIs directly to the browser and offers a simple path to maintain cross-browser support without forcing users into complicated manual drivers. For end users, this means straightforward setup and safer interactions with dApps and the official Trezor Suite.

Design goals

  • Security: keep private keys on the Trezor device and limit what is transmitted between the device and host apps.
  • Compatibility: support Windows, macOS, and Linux with browsers and desktop apps that rely on standard WebUSB/WebHID patterns.
  • Simplicity: provide a one-click installer and automatic updates (where supported) so users spend less time configuring and more time transacting securely.

Installation & first-time setup

Installing Bridge is straightforward: download the official installer for your platform from the Trezor website and run the installer. On first run Bridge will start a local service that listens only on loopback (localhost). Many users will then be directed to open Trezor Suite (web or desktop) or another supported app which will automatically detect the Bridge and the connected device.

Step-by-step

  1. Go to the official Trezor Bridge download page.
  2. Choose the correct installer for your operating system and follow the guided steps.
  3. Once installed, connect your Trezor device via USB and open the Trezor Suite or a compatible web app.
  4. Approve the device connection on the Trezor hardware when prompted; never approve unexpected requests.

Security & privacy considerations

Bridge is intentionally minimal: it does not collect your seed, mnemonic, private keys, or transaction data. It only passes requests between approved local applications and the device. Still, treat the Bridge like any other local service: install it from the official site, keep it updated, and avoid running untrusted applications that request device access.

Best practices

  • Always download Bridge from the official domain or links provided in official Trezor documentation.
  • Keep your Bridge and Trezor firmware up to date — updates contain security improvements and compatibility fixes.
  • Only authorize device connections from sites or apps you trust; verify domain names in the browser and check for HTTPS.
  • Use a dedicated browser profile for crypto interactions to reduce cross-extension risks and minimize exposure.

Troubleshooting common issues

Users occasionally experience problems such as the device not being detected, Bridge not starting, or browser prompts failing. Most of these are resolved with a few quick checks.

Quick fixes

  • Restart Bridge: quit the Bridge application and relaunch it.
  • Try a different USB cable or port; faulty cables are a common cause of connection issues.
  • Ensure your browser is up to date and supports the required APIs (WebUSB/WebHID); try another browser if needed.
  • Check firewall or antivirus settings — some security tools may block local loopback services. Allow Bridge when prompted.

Advanced topics for power users

Advanced users may want to run their own node, use specific browser settings, or integrate Bridge with custom tooling. Bridge can be combined with local services for enhanced privacy and control, but each change increases complexity. If you choose advanced configurations, document your steps, backup any important configuration files, and consult official developer resources.

Developer & integration resources

Developers can explore Trezor’s GitHub repositories and developer docs to learn more about the communication protocols, signing flows, and ways to validate Bridge behavior. If you are integrating with a service, make sure to follow the recommended security model and respect user consent flows.

FAQs — quick answers

Do I need Bridge to use Trezor Suite?

For many desktop integrations the Bridge is required to allow the browser or local app to detect and communicate with the device. Some native desktop versions may bundle the necessary connectivity or require alternative drivers.

Is Bridge safe to run on my machine?

Yes — Bridge is designed to run locally and only listens on your computer. Install from official sources and keep it updated to maintain security.

Final words — keep control, stay informed

Trezor Bridge plays an essential role in the secure user experience by enabling seamless, safe connections between your Trezor hardware and the digital services you rely on. It is deliberately minimal and local-first so you retain custody of your keys while enjoying modern web and desktop functionality. When in doubt, consult the official resources above, verify downloads and domains, and follow security best practices: your recovery seed and device PIN are the ultimate gatekeepers to your crypto.
