What is Trezor Bridge?
Trezor Bridge is a secure communication tool that enables your web browser to interact with your Trezor hardware wallet. This essential software runs in the background on your computer, creating a secure channel between your browser and your Trezor device.
Unlike standalone applications like Trezor Suite, the web interface at wallet.trezor.io requires Trezor Bridge to communicate with your hardware wallet. This ensures that even when using browser-based access, your private keys remain securely stored on your device and never exposed to your computer or the internet.
How Trezor Bridge Enhances Security
Trezor Bridge employs advanced encryption protocols to secure communication between your browser and hardware wallet. This creates a protected channel that:
- Prevents man-in-the-middle attacks
- Ensures only authorized applications access your device
- Protects against malicious browser extensions
- Maintains end-to-end encryption for all communications

Trezor Bridge vs Trezor Suite
While both solutions enable you to interact with your Trezor hardware wallet, they serve different purposes:

Trezor Suite
A full-featured desktop application that includes built-in communication capabilities. Doesn't require Bridge installation. Offers advanced features like portfolio tracking, coin control, and Tor integration.
