What Is Trezor Bridge?

Trezor Bridge is a small background software developed by SatoshiLabs that enables smooth communication between Trezor hardware wallets and your web browser. It acts as a secure connection layer, allowing your Trezor device to interact with web-based interfaces such as Trezor Suite (web version) and other supported third-party wallets.

Without Trezor Bridge installed, your computer’s browser may not recognize the Trezor device properly, especially on modern browsers that no longer support older USB communication methods.

Why Trezor Bridge Is Important

Trezor Bridge plays a crucial role in ensuring that transactions, confirmations, and wallet data are transferred securely between your hardware wallet and your computer. It works silently in the background and does not require manual interaction once installed.

Key benefits include:

  • Reliable USB communication with Trezor devices
  • Improved compatibility with modern browsers
  • Secure data transfer without exposing private keys
  • Automatic detection of connected Trezor wallets

How Trezor Bridge Works

When you connect your Trezor device to a computer, Trezor Bridge acts as an intermediary. The browser sends requests to the Bridge, and the Bridge communicates directly with the hardware wallet via USB. All sensitive operations—such as signing transactions—are performed inside the Trezor device itself, ensuring maximum security.

Trezor Bridge starts automatically when your system boots and runs quietly in the background, ensuring your device is always ready when needed.

Supported Devices and Systems

Trezor Bridge supports:

  • Trezor Model One
  • Trezor Model T

It is compatible with major operating systems including:

  • Windows
  • macOS
  • Linux

The software is lightweight and frequently updated to maintain compatibility and security.

How to Install Trezor Bridge

To install Trezor Bridge, users should visit the official trezor.io/start page and follow the on-screen instructions. The installer automatically detects your operating system and guides you through the setup process. Once installed, simply reconnect your Trezor device and refresh your browser.

Frequently Asked Questions (FAQs)

Is Trezor Bridge safe to use?

Yes. Trezor Bridge is an official tool from SatoshiLabs and does not store private keys or sensitive wallet information.

Do I still need Trezor Bridge if I use Trezor Suite Desktop?

No. The desktop version of Trezor Suite has built-in device communication, so Trezor Bridge is mainly required for browser-based access.

Can I uninstall Trezor Bridge?

Yes, you can uninstall it if you no longer use browser-based wallets that require it.

Does Trezor Bridge run all the time?

It runs in the background only to enable device detection and does not affect system performance.

What if my Trezor is not detected?

Ensure Trezor Bridge is installed, updated, and that no conflicting wallet software is running.
