Secure communication between your Trezor hardware wallet and web browser

What is Trezor Bridge?

Trezor Bridge is a background service that enables secure communication between your Trezor hardware wallet and supported web browsers. It acts as a facilitator that allows your browser to interact with your Trezor device without compromising security.

Unlike browser extensions, Trezor Bridge runs as a standalone application in the background, providing a more stable and secure connection to manage your cryptocurrency assets through web interfaces like the Trezor Wallet.
