What is Trezor Bridge?

Trezor Bridge is a lightweight software that connects your Trezor hardware wallet to your computer’s web browser. It works as a secure communication link between your Trezor device and the Trezor Suite web app (or third-party wallet services that support Trezor).

Older versions of Trezor connectivity used a browser plugin called the Trezor Chrome Extension, but this was replaced by Trezor Bridge for better security and broader compatibility with different operating systems and browsers.

Without Trezor Bridge, your computer can’t fully communicate with your Trezor device because modern browsers don’t directly access USB devices in a secure way. So, installing Trezor Bridge is essential for signing transactions, managing your crypto assets, or using Trezor Suite in your browser.
