What is Trézór Bridge?
Trézór Bridge is a software application that acts as the vital connection between your Trezor hardware wallet and web browsers, enabling secure communication required for managing cryptocurrencies safely online. Developed by SatoshiLabs, Bridge runs silently in the background, detecting your Trezor device and facilitating encrypted data transfer to and from supported wallet and dApp interfaces.
For years, Trézór Bridge has ensured compatibility and smooth device communication across multiple browsers and operating systems, replacing older plug-in methods and enhancing security.
Why Do You Need Trézór Bridge?
Modern browsers have been evolving their security and device access protocols, introducing APIs like WebUSB and WebHID, which allow direct hardware communication without external software. This transition has affected the role of Trézór Bridge:
- In browsers like Google Chrome and Microsoft Edge (Chromium-based), WebUSB is preferred, sometimes making Bridge optional as the browser talks directly to your device.
- Mozilla Firefox still primarily requires Trézór Bridge because it lacks full WebUSB support, making Bridge essential for continuing use.
- Safari on macOS also depends on Trézór Bridge due to absent native WebUSB support.
Trézór Bridge ensures backward compatibility and consistent communication in browsers and platforms that have not fully embraced new standards.
