Trezor Bridge – The Connection Between Your Browser and Trezor Device
Trezor Bridge is a communication tool that allows your Trezor hardware wallet to interact with web applications (like Trezor Suite Web) through your internet browser. It acts as a secure communication layer between your Trezor device and your computer's browser, ensuring smooth and secure functionality without exposing sensitive data.
🔍 What is Trezor Bridge?
Trezor Bridge is a small background service (software) you install on your computer. Once installed, it runs silently and ensures that your Trezor hardware wallet can connect and communicate with supported browsers like Chrome, Firefox, and Edge — especially when using the web version of Trezor Suite.
Without it, the browser can't directly communicate with your Trezor device due to USB security restrictions in most modern browsers.
🧩 Why Do You Need Trezor Bridge?
To Use Trezor on Web Browsers
If you're using suite.trezor.io/web, the Trezor Bridge is required for your browser to detect your Trezor device.
Secure Communication
It ensures end-to-end encrypted communication between your device and browser, keeping your transactions safe.
Browser Compatibility
Trezor Bridge ensures compatibility across various browsers without requiring browser extensions.
🛠️ How to Install Trezor Bridge
Visit the official download page:
https://trezor.io/bridge
Choose the version for your operating system (Windows, macOS, or Linux).
Download and install the Bridge application.
After installation, refresh your browser or restart your computer.
Once installed, your browser will be able to detect your Trezor device whenever it’s plugged in.
🔐 Is Trezor Bridge Safe?
Yes — Trezor Bridge is developed and maintained by SatoshiLabs, the creators of Trezor. It is open-source, digitally signed, and thoroughly tested. It does not store any personal information or private keys. All sensitive actions must still be confirmed directly on your Trezor hardware device.
✅ When to Use Trezor Bridge
When using Trezor Suite Web instead of the desktop app
When your browser does not detect your Trezor device
When setting up your Trezor for the first time via web
When using Trezor integrations with third-party services
Note: If you're using the Trezor Suite Desktop app, you do not need Trezor Bridge — the desktop app communicates with your device directly.
🧾 Conclusion
Trezor Bridge is a lightweight but essential tool that enables secure communication between your browser and your Trezor hardware wallet. It’s easy to install, runs silently in the background, and ensures a smooth experience when using Trezor’s web-based tools. Always download Trezor Bridge from the official website to avoid any risk of tampered files.
