Trezor Bridge | Secure Connection Between Your Trezor and Browser
Trezor Bridge is a background service that enables secure communication between your Trezor hardware wallet and web-based applications. It acts as a trusted bridge between your device and supported browsers, ensuring that transactions and sensitive actions are performed safely without exposing private keys.
Trezor Bridge is essential for users who prefer managing their crypto assets through the Trezor Suite Web interface or compatible third-party wallets directly in a browser.
What Is Trezor Bridge?
Trezor Bridge is a lightweight software component installed on your computer that allows your browser to detect and communicate with your Trezor hardware wallet.
Its main purpose is to:
Enable browser-based wallet access
Ensure secure device recognition
Protect communication between your Trezor and supported web apps
Without Trezor Bridge, your browser may not be able to interact with your Trezor device correctly.
Why Trezor Bridge Is Important
Modern browsers limit direct access to USB devices for security reasons. Trezor Bridge solves this by acting as a trusted intermediary.
Key benefits include:
Secure device communication
No private key exposure
Automatic device detection
Compatibility with major browsers
Trezor Bridge is especially useful when accessing wallets via Trezor Suite Web or trusted third-party services.
How Trezor Bridge Works
Trezor Bridge runs quietly in the background after installation. When you connect your Trezor device:
Your browser sends a request
Trezor Bridge securely passes the request to the device
The device processes the request
User confirmation is required on the Trezor screen
The response is sent back through the Bridge
At no point do your private keys leave the hardware wallet.
