Trezor Bridge®: Secure Browser Connection for Your Trezor Device

Overview

Trezor Bridge® is an essential piece of software that provides a secure connection between your Trezor hardware wallet and web browsers. Its primary function is to allow users to safely interact with web wallets, decentralized applications (dApps), and cryptocurrency exchanges without exposing private keys to potential online threats.
