Trezor Bridge

What is Trezor Bridge?

Trezor Bridge is an official background service developed by SatoshiLabs that allows your computer’s web browser or the Trezor Suite desktop app to communicate with your Trezor hardware wallet.

When you plug in your Trezor device, the Bridge acts as a “middleman,” securely transferring data between your Trezor and the software interface. Without it, browsers and desktop applications would not be able to detect or interact with your Trezor device properly.

Think of Trezor Bridge as the “driver” for your hardware wallet — similar to how a printer driver allows your computer to communicate with your printer. It ensures smooth, encrypted, and secure communication between your device and your apps.

How to Install Trezor Bridge

Follow these simple steps to download and install Trezor Bridge safely:

1. Visit the official website: Go to https://trezor.io/bridge/. Avoid using links from unofficial or third-party websites.
2. Download the installer: Choose the version compatible with your operating system — Windows, macOS, or Linux.
3. Install the Bridge: Run the installer file and follow on-screen instructions. You may need to grant administrative permissions.
4. Restart your browser or system: Once installed, restart your web browser or computer to activate the Bridge service.
5. Connect your Trezor device: Plug in your Trezor, open Trezor Suite Web, or launch the desktop version. The device should now be detected automatically.

If your browser still cannot detect your Trezor device, check your USB connection, update your browser, or reinstall the Bridge using the official link.

Key Features of Trezor Bridge

• Secure Communication: Establishes encrypted channels between your Trezor device and Trezor Suite, ensuring data privacy.
• Automatic Device Detection: Instantly recognizes when a Trezor wallet is connected or disconnected.
• Background Operation: Runs silently in the background, requiring minimal user interaction.
• Cross-Browser Support: Compatible with Chrome, Brave, Firefox, and other modern browsers.
• Stable Performance: Prevents connection interruptions and ensures consistent device recognition.
• Automatic Updates: Keeps your Bridge version current to match firmware and software upgrades.

Supported Systems and Browsers

Trezor Bridge is designed to be lightweight and highly compatible with most devices. Below are the supported platforms:

• Operating Systems: Windows 10 and later, macOS 10.15 (Catalina) or newer, and major Linux distributions such as Ubuntu and Fedora.
• Browsers: Google Chrome, Mozilla Firefox, Brave, and Microsoft Edge (Chromium-based versions).

On browsers that support the WebUSB standard, such as Chrome and Brave, you can also connect your Trezor directly without Bridge. However, installing Trezor Bridge ensures wider compatibility, especially on browsers that do not natively support WebUSB.

Troubleshooting Common Issues

If you encounter problems connecting your Trezor device, here are some solutions:

• Device Not Detected: Ensure that Trezor Bridge is installed and running in the background. Restart the Bridge service if necessary.
• Connection Timeout: Try a different USB cable or port. Avoid USB hubs or extension cords.
• Browser Compatibility: Switch to Chrome or Brave for the best results with Trezor Bridge.
• Firewall Restrictions: Disable any software firewall temporarily if it blocks Bridge communication.
• Reinstall Bridge: Uninstall and reinstall the latest version from trezor.io/bridge.

If problems persist, open Trezor Suite Web and follow on-screen troubleshooting steps or contact Trezor Support.
