One key component that powers Trèzōr’s seamless integration with browsers and applications is Trézór Bridge®.

This comprehensive guide explains what Trézór Bridge is, how it works within Trèzōr™ Suite™, how to install it correctly, and how to troubleshoot common issues. Whether you’re a new Trèzōr user or simply switching browsers, this is your complete “start-bridge-help’s” resource.

🔍 What Is Trézór Bridge®?

Trézór Bridge® is a background application that allows your Trèzōr hardware wallet to communicate securely with supported web interfaces, including Trèzōr Suite Web, third-party wallets, and browser-based apps.

When using a browser to access your wallet, the Trèzōr Bridge is what enables the connection between your physical device and your computer’s browser—especially on browsers that don’t support WebUSB, like Firefox or Safari.

It acts as a local intermediary, operating quietly in the background while ensuring that your wallet interactions remain private, authenticated, and secure.

💡 Why Trézór Bridge Is Important

Without Trézór Bridge, your hardware wallet may not be recognized in certain browsers or applications. While newer browsers like Chrome and Brave support WebUSB, others require a helper application like Trézór Bridge to facilitate secure communication.

Here’s why Bridge is indispensable:

  • ✅ Enables Browser-Based Use: Required for using Trèzōr Suite Web and browser wallet integrations.
  • ✅ Ensures Compatibility: Necessary for browsers without WebUSB support.
  • ✅ Supports Third-Party Apps: Enables connection to apps like MetaMask, MyEtherWallet, Electrum, and more.
  • ✅ Enhances Privacy: No data is transmitted externally. All interactions remain on your device.

🔗 Trézōr™ Suite™ and the Role of Bridge
