What is Trezor Bridge?
Trezor Bridge is a lightweight background software that facilitates communication between your Trezor hardware wallet and supported web browsers or web-based applications such as Trezor Suite Web. It acts as a bridge between the Trezor device and your internet browser, ensuring smooth, secure, and real-time interaction for transaction confirmations, firmware updates, wallet access, and more.
Unlike browser extensions or other third-party tools, Trezor Bridge is developed and maintained by SatoshiLabs—the creators of Trezor wallets—ensuring trusted and secure communication between your device and Trezor Suite or other compatible apps.
Why Do You Need Trezor Bridge?
Trezor Bridge is required when you are using the web version of Trezor Suite or other tools that interact with your hardware wallet via a browser. Without the Bridge installed, your browser may not detect your Trezor device, making it impossible to manage your assets or confirm transactions.

Trezor Bridge vs WebUSB
Some modern browsers (like Chrome) support direct USB communication using WebUSB. However, WebUSB may have compatibility issues or may not work in all environments. Trezor Bridge offers a more stable, consistent experience across platforms and browsers.

- WebUSB: Optional, but limited support
Troubleshooting Trezor Bridge
Device not detected
If your Trezor is not recognized, check your USB cable or port. Make sure Trezor Bridge is running in the background. Restart the browser and reconnect your device.
Bridge not starting
Ensure that the installation was successful and you have permissions to run system services. On Linux, you may need to enable USB rules.
Firewall or antivirus blocking it
Add Trezor Bridge to your trusted applications or whitelist it in your firewall and antivirus settings.

Trezor Bridge is open-source and does not collect any personal or private data. It runs only on your local machine and connects only to your Trezor device and the Trezor Suite Web.
The application is regularly audited by the developer community and undergoes frequent updates to maintain security standards.
