Trezor Bridge — What It Is and How to Install It

Trezor Bridge is a communication tool that allows your Trezor hardware wallet to connect securely with your web browser and the Trezor Suite web application. It runs quietly in the background and ensures smooth interaction between your device and supported web interfaces.

If you're setting up your device through Trezor.io/start or using the web version of Trezor Suite, you may be prompted to install Trezor Bridge to enable proper device detection.

What Is Trezor Bridge?

Trezor Bridge is a lightweight software component developed by SatoshiLabs. Its main purpose is to:

• Enable browser communication with your Trezor device
• Replace older browser extensions previously used for connectivity
• Provide secure data transmission between the wallet and web interface
• Ensure compatibility across different operating systems

Unlike browser plugins, Trezor Bridge runs as a background service on your computer, improving reliability and security.

Why Do You Need Trezor Bridge?

When using the Trezor Suite web version, your browser needs a secure method to communicate with your hardware wallet via USB. Modern browsers limit direct hardware communication for security reasons, which is where Trezor Bridge comes in.

You may need Trezor Bridge if:

• Your Trezor device is not detected in the browser
• You are using Trezor Suite in a web browser instead of the desktop app
• You are accessing supported third-party wallet interfaces

If you're using the Trezor Suite desktop application, Trezor Bridge is usually not required because the desktop app has built-in communication support.

How to Install Trezor Bridge

Follow these steps to install Trezor Bridge safely:

1. Visit the Official Website

Go to the official Trezor website. Always type the URL manually to avoid phishing attempts.

2. Download Trezor Bridge

Navigate to the download section and select the version compatible with your operating system (Windows, macOS, or Linux).

3. Install the Software

Open the downloaded file and follow the installation prompts.

4. Restart Your Browser

After installation, restart your browser to ensure the connection is properly established.

Once installed, Trezor Bridge runs automatically in the background when needed.

How to Check if Trezor Bridge Is Working

After installing:

1. Connect your Trezor device via USB
2. Open Trezor Suite web
3. If the device is detected without errors, Trezor Bridge is functioning properly

If the device is still not detected, try:

• Restarting your computer
• Using a different USB cable
• Switching USB ports
• Ensuring no firewall is blocking the service

Trezor Bridge vs Trezor Suite Desktop

It’s important to understand the difference:

• Trezor Bridge: Enables browser-based communication
• Trezor Suite Desktop: Standalone application with built-in connectivity

For maximum security and stability, many users prefer Trezor Suite Desktop since it does not rely on browser communication.

Security Tips

When installing and using Trezor Bridge:

• Download only from the official Trezor website
• Never install software from third-party links
• Keep your operating system updated
• Do not share your recovery seed under any circumstances

Remember, Trezor Bridge does not store your private keys. Your keys remain securely stored on your hardware wallet.

Final Thoughts

Trezor Bridge plays a key role in enabling secure communication between your Trezor device and web applications. While optional for desktop users, it is essential for those accessing Trezor through a browser.

By installing Trezor Bridge from official sources and following security best practices, you ensure a safe and seamless hardware wallet experience.
