What is Trezor Bridge?
Trezor Bridge is a lightweight background service that enables secure communication between your Trezor hardware wallet and supported web browsers. It acts as a facilitator that allows your Trezor device to interact with web-based applications like the Trezor Wallet interface, MyEtherWallet, and other compatible services without compromising security.
Trezor Bridge ensures that your private keys never leave your Trezor device, maintaining the highest level of security while providing seamless connectivity to web applications.
Unlike browser extensions that might have security vulnerabilities, Trezor Bridge runs as a separate application on your computer, creating a secure channel between your hardware wallet and the browser. This architecture prevents potential browser-based attacks from compromising your cryptocurrency assets.
