What is Trezor Bridge?
Trezor Bridge is a small utility that acts as a secure communication layer between your web browser and your Trezor hardware wallet. When you access web-based apps like the Trezor Suite (web version), Trezor Bridge allows these apps to securely detect and communicate with your device over USB.
Without Trezor Bridge, your browser would not be able to connect to your Trezor device in a secure and reliable way. It replaces older solutions like browser extensions and ensures a safer, smoother user experience.
Why Do You Need It?
- 🔐 Enables secure browser communication with your Trezor wallet
- 🖥️ Required for using Trezor Suite Web
- 🧩 Works with all major browsers (Chrome, Firefox, Brave, Edge)
- 🔄 Lightweight and runs quietly in the background
Trezor Bridge is especially important if you prefer the web-based version of Trezor Suite or if you interact with third-party services that require hardware wallet authentication in the browser.
How Trezor Bridge Works
Trezor Bridge listens on your computer locally and allows approved browser-based apps to interact with your hardware wallet. It uses HTTPS over localhost to securely deliver commands between your browser and your device.
Once installed, it runs as a background service and automatically starts when your computer boots. You’ll rarely need to interact with it directly.
How to Install Trezor Bridge
Installing Trezor Bridge is fast and easy. Just follow these steps:
- Go to the official Trezor Bridge download page: trezor.io/bridge
- Select your operating system (Windows, macOS, or Linux)
- Download and run the installer
- Follow the on-screen prompts to complete installation
- Restart your browser if prompted
System Requirements
- Operating Systems: Windows 10+, macOS 10.11+, Linux (Debian-based)
- Browsers: Chrome, Firefox, Edge, Brave
- Hardware: Trezor Model T or Trezor Model One
If you're using the Trezor Suite desktop app, you don’t need Bridge — it’s only required for browser-based usage.

Security and Privacy
Trezor Bridge is open-source and developed by SatoshiLabs, the creators of the Trezor hardware wallet. It runs locally and does not send any personal or private data to external servers.
Only approved applications can interact with your device via Bridge, and all sensitive actions still require physical confirmation on your Trezor hardware wallet.
When You Don’t Need Bridge
- If you are using the Trezor Suite Desktop App
- If your browser supports WebUSB and you use that instead
- If you only interact with your wallet via mobile (using third-party apps)
Bridge is specifically designed for secure communication between browser-based apps and desktop Trezor devices.
