Trézor Bridge® | Introducing the New Trezor® App
Trezor Bridge is a lightweight background application developed by Trezor that enables seamless communication between your Trezor hardware wallet and your web browser. It acts as a secure connector, ensuring your device can interact safely with supported web applications like Trezor Suite (Web).
If your Trezor device is not being recognized in the browser, installing or updating Trezor Bridge is often the solution.
🔐 What Is Trezor Bridge?
Trezor Bridge is a small software component that:
- Connects your Trezor device to supported browsers
- Replaces older browser extensions
- Runs quietly in the background
- Ensures encrypted communication
It allows secure data exchange between your hardware wallet and web-based crypto management tools—without exposing your private keys.
🧩 Why Is Trezor Bridge Needed?
Modern browsers restrict direct USB communication for security reasons. Trezor Bridge solves this by acting as a secure intermediary.
It ensures:
- Stable USB device detection
- Secure encrypted connection
- Compatibility with supported browsers
- Smooth user experience
Without Trezor Bridge, your browser may fail to detect your device.
💻 When Do You Need Trezor Bridge?
You may need Trezor Bridge if:
- Your device is not recognized in web-based Trezor Suite
- You’re using the browser version instead of the desktop app
- You see a prompt asking to install Bridge
- You're setting up your device for the first time
If you use the Trezor Suite desktop application, Bridge is typically not required.
