Trezor Bridge

What is Trezor Bridge?

Trezor Bridge is a secure communication layer designed to connect your Trezor hardware wallet to your computer’s browser or application. It acts as an intermediary software that allows your device and computer to interact seamlessly without exposing your private keys to the internet.

Unlike traditional USB communication protocols that may be blocked or limited by modern browsers for security reasons, Trezor Bridge uses a custom protocol optimized for hardware wallet communication, making it essential for using Trezor with the Trezor Suite, web wallets, and third-party applications.

How Does Trezor Bridge Work?

When you connect your Trezor device to your computer, Trezor Bridge establishes a secure and encrypted communication channel between the two. Here’s a simplified overview:

• Device Detection: Trezor Bridge listens for connected Trezor devices over USB.
• Message Handling: It relays data packets (transaction signing requests, device status, firmware updates) securely to and from the device.
• Browser Integration: Trezor Bridge interacts with your browser or desktop app, enabling web apps to communicate with your hardware wallet seamlessly.
• Security Controls: All sensitive actions require your physical confirmation on the device before being approved.

This architecture ensures your private keys never leave the hardware wallet, protecting your crypto assets even when connected to an internet-enabled computer.
