What is Trezor Bridge?
Trezor Bridge is a crucial piece of software developed by SatoshiLabs that serves as a secure communication layer between your Trezor hardware wallet and web browsers. In the evolving landscape of web security, modern browsers have implemented strict policies that prevent websites from directly communicating with USB devices. This is where Trezor Bridge becomes indispensable.
Acting as a trusted intermediary, Trezor Bridge creates a secure channel that allows authorized web applications to interact with your Trezor device while maintaining the highest security standards. The software operates as a lightweight background service, automatically activating when you connect your Trezor and visit compatible cryptocurrency websites or applications.
The Bridge application is designed with security as the primary focus. It never accesses, stores, or transmits your private keys or sensitive wallet data. Instead, it simply facilitates the secure passage of transaction signing requests and device communication protocols, ensuring that your cryptocurrency assets remain protected at all times.

This architecture ensures that all data transmission remains encrypted and protected from network-based attacks.
The software implements WebUSB-like functionality through a secure proxy layer, allowing modern web browsers to communicate with USB devices while maintaining strict security boundaries. Each communication session is individually encrypted using industry-standard protocols, ensuring that sensitive wallet operations remain completely secure.
Bridge supports multiple concurrent connections and can handle various cryptocurrency operations simultaneously, including transaction signing, address verification, message signing, and firmware updates. The application is designed to be lightweight, consuming minimal system resources while providing robust, reliable connectivity.
