Trezor Bridge is an essential background service developed by SatoshiLabs that allows your Trezor hardware wallet to communicate securely with supported web browsers and online interfaces. It acts as a trusted intermediary, ensuring encrypted and verified communication between your device and software without exposing private keys.
What Is Trezor Bridge?
Trezor Bridge replaces older browser plugins by providing a modern, lightweight, and secure method for browser-to-device communication. Instead of relying on browser extensions, Trezor Bridge runs locally on your computer and enables supported websites such as Trezor Suite Web to detect and interact with your hardware wallet.
This approach significantly improves security, reliability, and compatibility across different operating systems and browsers.
Why Trezor Bridge Is Important
- Eliminates insecure browser plugins
- Provides encrypted local communication
- Ensures device authenticity verification
- Improves compatibility with modern browsers
- Enables seamless wallet interactions
How Trezor Bridge Works
Trezor Bridge operates as a local service that listens for requests from supported web applications. When a browser-based wallet interface requires access to your Trezor device, it communicates with Trezor Bridge, which then securely relays instructions to the hardware wallet.
All sensitive actions such as transaction signing or account access must be physically confirmed on the Trezor device, ensuring maximum protection against malware or phishing attacks.
