What Is Trezor Bridge®?
Trezor Bridge® is a background service that allows web browsers to communicate with your Trezor hardware wallet. Modern browsers restrict direct access to USB devices for security reasons. Trezor Bridge solves this problem by acting as a trusted intermediary between your Trezor device and web-based platforms like Trezor Suite Web or third-party crypto services.
Without Trezor Bridge, your browser would not be able to detect or interact with your Trezor wallet reliably. Once installed, it runs quietly in the background, ensuring smooth, encrypted communication whenever you connect your device.
Why Trezor Bridge Is Important
The importance of Trezor Bridge lies in its ability to balance strong security with user convenience. Hardware wallets are designed to keep private keys offline, but users still need a safe way to interact with online services.
Key reasons Trezor Bridge is essential:
Enables secure USB communication between your device and web apps
Prevents unauthorized access to your Trezor
Works across major operating systems
Reduces reliance on insecure browser plugins
Ensures compatibility with Trezor Suite Web and trusted third-party services
By using Trezor Bridge, users avoid exposing sensitive data while still enjoying the flexibility of web-based crypto management.
How Trezor Bridge Works
Trezor Bridge operates as a local service installed on your computer. When you connect your Trezor hardware wallet via USB, Trezor Bridge detects the device and waits for communication requests from supported web applications.
Here’s how the process works in simple terms:
You connect your Trezor device to your computer
Trezor Bridge detects the hardware wallet
A web application sends a request (such as signing a transaction)
Trezor Bridge forwards the request securely to the device
You confirm the action physically on your Trezor
The signed response is sent back through Trezor Bridge
At no point do your private keys leave the hardware wallet, ensuring maximum security.
Supported Operating Systems
Trezor Bridge® is compatible with all major desktop operating systems, making it accessible to a wide range of users worldwide.
Supported platforms include:
Windows (10 and later)
macOS
Linux
The installation packages are optimized for each operating system and maintained by Trezor to ensure stability and security updates.

Trezor Bridge vs Browser Extensions
In the past, browser extensions were commonly used to connect hardware wallets to web apps. However, extensions can introduce additional security risks due to their access to browser data and permissions.
Trezor Bridge offers several advantages over browser extensions:
Runs independently of the browser
Reduced attack surface
Works across multiple browsers simultaneously
Regularly updated and audited by Trezor
More stable and reliable for long-term use
Because of these advantages, Trezor recommends Trezor Bridge as the preferred connection method for web-based interactions.
