Trezor Bridge

Secure local bridge for your Trezor hardware wallet — connect Trezor Bridge to Trezor Suite and web apps.

What is Trezor Bridge?

Trezor Bridge is a lightweight application that runs on your computer to create a secure local connection between your Trezor hardware wallet and applications such as Trezor Suite, browser-based wallets, and developer tools. Trezor Bridge handles USB communication, ensures that the Trezor device remains isolated for security, and provides a stable channel for signing transactions. Using Trezor Bridge helps keep your keys safe while enabling smooth interaction with the leading Trezor Suite software and web integrations.
