What Is Trezor Bridge? – A Complete Guide to Connecting Your Trezor Wallet

If you're using a Trezor hardware wallet to store your cryptocurrency, Trezor Bridge is the critical link between your wallet and your browser. This lightweight communication tool allows your browser to securely interact with your Trezor device, enabling safe crypto transactions and access to essential wallet features.

Whether you're new to Trezor or looking to troubleshoot connectivity, this guide will walk you through what Trezor Bridge does, how to install it, and why it's important.

What Is Trezor Bridge?

Trezor Bridge is a software application that runs in the background on your computer, allowing web-based wallet interfaces—such as Trezor Suite or the Trezor web wallet—to communicate with your physical Trezor hardware wallet via USB.

Without Trezor Bridge, your browser wouldn’t be able to recognize the Trezor device, preventing essential wallet functions like:

Accessing your crypto balances
Sending or receiving cryptocurrency
Confirming transactions
Updating firmware securely

Trezor Bridge replaces the deprecated Trezor Chrome Extension, offering a more secure and flexible solution.

How to Install Trezor Bridge

Step-by-step installation:

Visit the official site:

Go to trezor.io/start or trezor.io/bridge
Download the correct version:

Choose your operating system (Windows, macOS, or Linux) and download the Bridge installer.
Install the software:

Run the downloaded file and follow the on-screen instructions.
Restart your browser:

After installation, close and reopen your browser for the changes to take effect.
Connect your Trezor device via USB:

Open Trezor Suite or go to the Trezor web wallet—your device should now be detected automatically.

Key Features of Trezor Bridge

Secure Communication: Encrypts the connection between your Trezor device and web browser.
Lightweight: Runs quietly in the background without draining system resources.
Automatic Updates: Keeps itself updated to maintain compatibility with new firmware versions.
Cross-Browser Support: Works with all major browsers (except those requiring web extensions like Firefox without permissions).

Do You Need Trezor Bridge?

You need Trezor Bridge if you're:

Using the Trezor web wallet in your browser
Accessing third-party crypto wallets that require direct Trezor interaction
Not using the Trezor Suite desktop app (which doesn’t require Bridge)

Note: If you're using Trezor Suite (desktop version), you do not need to install Trezor Bridge—Suite handles communication directly.

Troubleshooting Trezor Bridge

If your browser can't detect your Trezor wallet even after installation:

Make sure Bridge is running in your system tray or task manager
Restart your browser and reconnect your Trezor device
Try a different USB cable or port
Disable browser extensions that may block device communication
Ensure your browser is up to date

If all else fails, uninstall and reinstall Trezor Bridge from the official site.
