What is Trézor Bridge®?
Trézor Bridge® is a lightweight, secure helper application that enables your Trézor hardware wallet to communicate with desktop browsers and web-based wallets. It acts as a trusted gateway between the physical device and web interfaces so transactions can be prepared in your browser and safely signed on the device itself. Designed with privacy and minimal footprint in mind, Trézor Bridge keeps your private keys offline while providing a reliable connection for everyday use.
Key Features
- Secure Communication: Encrypted local channel between your browser and Trézor device — no private keys leave the hardware.
- Cross-Platform Support: Available for Windows, macOS, and Linux with easy installers and stable releases.
- Browser Integration: Works with popular browsers to enable trusted web apps and decentralized applications (dApps).
- Small Footprint: Lightweight background service that runs only when needed.
- Automatic Updates: Optional update checks to keep the Bridge secure and compatible with firmware and web apps.
- Compatibility Layer: Smoothly connects Trezor One and Trézor Model T to the Trezor Suite and third-party wallets.
Why Use Trézor Bridge®?
Trézor Bridge brings the convenience of browser-based wallets together with the security of a hardware device. Instead of exposing keys to the internet, Bridge routes transaction requests to your Trézor, where every transaction is displayed and confirmed manually. This separation drastically reduces phishing, malware, and keylogger risks — while keeping the user experience smooth and fast.
How to Install & Connect
- Download the official Trézor Bridge installer from the Trézor website or the Trezor Suite download page.
- Run the installer and follow on-screen instructions (Windows/macOS/Linux packages available).
- Open your browser and visit a supported web app or Trezor Suite. The site will detect Bridge automatically.
- Connect your Trézor via USB. Authorize the connection by confirming on the device screen and entering your PIN if prompted.
- Confirm transactions directly on your Trézor — every sensitive operation requires manual approval.
Tip: If your browser prompts to allow the Bridge connection, accept it only on trusted sites such as the official Trezor web app.
Troubleshooting
- No device detected? Ensure the USB cable is fully connected and try a different USB port or cable.
- Bridge not running? Restart the Bridge service or reboot your computer and relaunch your browser.
- Browser warnings? Only accept permissions on official Trezor domains and avoid third-party links you do not recognize.
- Connection issues on Linux? Confirm udev rules are installed (the installer typically sets them up) and that your user has proper permissions.
- Still stuck? Check the official Trézor support documentation or the Trezor community for step-by-step guides.
