Master your crypto connection with our complete, human-friendly walkthrough of Trezor Bridge. Learn how to install, use, and troubleshoot — all in one place.
What is Trezor Bridge?
Trezor Bridge is the secure communication layer between your Trezor hardware wallet and your desktop browser. It allows websites and the Trezor Suite app to communicate directly with your Trezor device — securely and seamlessly.
If you’re planning to use your Trezor with web apps or the desktop Trezor Suite, Bridge is a must-have. Think of it as a translator between your browser and your wallet.
How to Install Trezor Bridge
Getting started with Bridge is surprisingly simple:
Visit the official Trezor site and download Bridge for your operating system (Windows, macOS, Linux).
Run the installer and follow the on-screen prompts.
Once installed, restart your browser and plug in your Trezor device.
Bridge will run in the background automatically whenever it’s needed.
You can confirm that it’s working by opening Trezor Suite — your device should be detected instantly.
Command-Line Uninstall (Advanced Users)
If you ever need to remove Bridge manually, use the following command (for advanced users):
sudo apt-get remove trezor-bridge
Always double-check you're not removing any dependencies needed by other apps.
Bridge vs. WebUSB
Browsers like Chrome support WebUSB, which lets you connect Trezor without Bridge. So why use Bridge?
Bridge works with more browsers (Firefox, Brave, Edge).
It ensures a stable, low-latency connection.
It’s essential for using older web apps or connecting via Trezor Suite desktop.
For most users, Bridge remains the most reliable option for everyday crypto management.
Troubleshooting Common Bridge Issues
Sometimes things don’t go as planned. Here are the most common issues and how to fix them:
Bridge Not Running: Reinstall and restart your browser. On macOS, make sure permissions are granted.
Device Not Detected: Check your USB cable and port. Use original cables if possible.
Still Not Working? Use Trezor Suite’s troubleshooting assistant or reinstall the latest Bridge version.
Security and Privacy
Trezor Bridge does not store personal data. It doesn’t log, transmit, or track anything — it simply acts as a secure pathway between your hardware wallet and the app you’re using.
It runs as a local service and only responds to signed, verified requests from Trezor Suite or approved websites.
