Connecting your hardware wallet to the digital world, safely.
In the evolving landscape of digital finance, the **Trezor hardware wallet** stands as a fortress for private keys. However, a fortress needs a drawbridge—a secure, controlled way for authorized access. This is the role of Trezor Bridge. It is a vital, lightweight application installed on your local machine that acts as a secure translator, enabling your web browser (running Trezor Suite) to communicate seamlessly and safely with your physical Trezor device via USB.
Modern web browsers intentionally restrict direct access to hardware devices for security. Trezor Bridge circumvents this limitation by operating locally. It sets up a secure communication channel (a local web server, often on http://127.0.0.1:21325) that the browser-based Trezor Suite is authorized to interact with. Crucially, the Bridge only handles **relaying commands and signed data**; it never has access to the sensitive private keys on your device.
No external servers are involved. The data exchange happens entirely between your browser, the Bridge app, and your physical Trezor, maximizing speed and minimizing interception risk.
The Bridge handles the complexity of low-level USB protocols. This makes the wallet's functionality reliable and consistent across different operating systems (Windows, macOS, Linux).
The Bridge features an automatic update mechanism, ensuring you always have the latest security patches and compatibility features without manual intervention.
