Trezor Bridge® — Connect Your Trezor to Web Browsers

Trezor Bridge® is an essential software component that allows Trezor hardware wallets to communicate securely with web browsers. Designed to act as a trusted connection layer, Trezor Bridge ensures that your device can interact seamlessly with browser-based applications such as Trezor Suite Web, third-party wallets, and supported crypto services—without compromising security.

If you use a Trezor device and prefer managing your crypto through a web interface, Trezor Bridge plays a critical role in making that experience smooth, private, and reliable.

What Is Trezor Bridge?

Trezor Bridge is a lightweight background application installed on your computer. Its primary function is to enable secure communication between your Trezor hardware wallet and your web browser.

Modern browsers no longer allow direct USB access for security reasons. Trezor Bridge solves this by acting as a local intermediary that:

• Detects your connected Trezor device

• Establishes a secure communication channel

• Allows browser-based wallet apps to interact with your device safely

Without Trezor Bridge (or supported alternatives like WebUSB), browsers would be unable to recognize your Trezor wallet.

Why Trezor Bridge Is Important

Security and usability are the core reasons Trezor Bridge exists. It ensures that sensitive operations—such as transaction signing and wallet access—remain isolated from the browser environment.

Key Benefits

• Enhanced Security – Private keys never leave your Trezor device

• Browser Compatibility – Works with major browsers like Chrome, Firefox, and Edge

• Stable Connection – Reduces USB and device recognition errors

• Automatic Updates – Keeps compatibility with new browser versions

Trezor Bridge is maintained by Trezor to ensure long-term reliability and safety.

How Trezor Bridge Works

Trezor Bridge runs silently in the background once installed. When you connect your Trezor hardware wallet via USB:

1. The Bridge detects the device

2. Your browser sends requests to Trezor Bridge

3. Trezor Bridge forwards those requests securely to your device

4. All sensitive actions are confirmed directly on the Trezor screen

This process ensures that even if a website is compromised, your funds remain protected because every transaction requires physical confirmation.

Supported Operating Systems

Trezor Bridge is available for the most common desktop platforms:

• Windows (10 and newer)

• macOS

• Linux

Each version is optimized for its operating system and integrates smoothly with supported browsers.

Browsers Compatible with Trezor Bridge

Trezor Bridge works with most modern browsers, including:

• Google Chrome

• Mozilla Firefox

• Microsoft Edge

• Brave

While some browsers support WebUSB, Trezor Bridge remains the most stable and widely compatible option, especially for advanced or frequent use.

Final Thoughts

Trezor Bridge® is a vital tool for connecting your Trezor hardware wallet to web browsers securely and efficiently. By acting as a trusted communication layer, it ensures that your private keys remain protected while allowing smooth interaction with browser-based crypto applications.
