Trezor Bridge® — Connect Your Trezor to Web Browsers

Managing cryptocurrency securely requires not only a reliable hardware wallet but also a robust way to connect it to your computer and web applications. Trezor Bridge® is the official software developed by SatoshiLabs that allows your Trezor device to communicate safely with web browsers such as Chrome, Brave, and Firefox. This connection is essential for accessing web-based crypto apps, signing transactions, and managing your assets without compromising security.

This guide will walk you through everything you need to know about Trezor Bridge®, including its purpose, installation, browser compatibility, security features, and troubleshooting.

What Is Trezor Bridge®?

Trezor Bridge® is a lightweight application that acts as a secure intermediary between your Trezor hardware wallet and web browsers. While Trezor Suite Desktop allows direct communication, some browsers require Bridge for seamless connectivity, particularly older browsers or those without native WebUSB support.

Key functions of Trezor Bridge® include:

  • Secure communication between your Trezor device and your browser
  • Transaction signing without exposing private keys online
  • Enabling access to Trezor Suite Web and other compatible crypto platforms
  • Providing a safe, background service without the need for browser extensions

Essentially, Trezor Bridge® ensures that your browser can detect and interact with your Trezor wallet safely and efficiently.

Why Trezor Bridge® Is Important

Web browsers cannot communicate directly with hardware wallets due to built-in security restrictions. Without Trezor Bridge®, certain browsers may fail to detect your device, which can prevent you from:

  • Managing your cryptocurrency accounts online
  • Signing and verifying transactions
  • Accessing advanced wallet features on web apps

Trezor Bridge® guarantees a secure, local communication channel, allowing your hardware wallet to function fully while keeping your private keys offline.
