Trézor Bridge® | Introducing the New Trezor® App

Trezor Bridge is a lightweight software component that enables communication between your Trezor hardware wallet and supported web browsers. It acts as a background service, allowing your browser-based applications—such as Trezor Suite Web—to securely detect and interact with your Trezor device.

If you use Trezor through a browser instead of the desktop version of Trezor Suite, Trezor Bridge ensures smooth and secure connectivity.

What Is Trezor Bridge?

Trezor Bridge is a small program installed on your computer that creates a secure connection between:

• Your Trezor hardware wallet (Model One or Model T)
• Your web browser (Chrome, Firefox, Edge, etc.)
• Web-based Trezor applications

Without Trezor Bridge, your browser may not recognize your connected Trezor device.

Why Is Trezor Bridge Important?

Modern browsers have strict security policies that limit direct USB communication with hardware devices. Trezor Bridge solves this by:

• Acting as a secure background service
• Enabling device detection
• Allowing encrypted communication
• Maintaining compatibility with web-based wallet interfaces

It ensures your private keys remain protected while allowing browser-based access.

When Do You Need Trezor Bridge?

You typically need Trezor Bridge if:

• You use Trezor Suite Web instead of the desktop app
• Your browser does not detect your device
• You are setting up your device via web interface
• You experience connection errors in browser mode

If you use the Trezor Suite Desktop app, Trezor Bridge is usually not required.

How Trezor Bridge Works

1. You connect your Trezor device via USB.

Private keys never leave your Trezor hardware wallet.

Trezor Bridge vs Trezor Suite Desktop

For maximum security and stability, the desktop version of Trezor Suite is recommended over browser use.

Best Practices

• Download only from the official Trezor website
• Keep Bridge updated
• Avoid public computers
• Never enter your recovery seed into browser popups
• Confirm all transactions on your Trezor device

Is Trezor Bridge Still Necessary?

With modern updates, many browsers now support WebUSB, reducing dependency on Bridge. However, Trezor Bridge remains important for compatibility and stable browser communication on some systems.

If you prefer maximum security and reliability, using Trezor Suite Desktop eliminates the need for Trezor Bridge.

Final Thoughts

Trezor Bridge is a secure communication tool that enables browser-based interaction with your Trezor hardware wallet. While lightweight and easy to install, it plays an essential role in ensuring safe device connectivity when using web interfaces.

For best performance and enhanced privacy, many users choose Trezor Suite Desktop, but Trezor Bridge remains a useful tool for web-based wallet access.
