Trezor Bridge® is the essential software for connecting your Trezor hardware wallet with supported browsers. Learn how it works, how to install it, and why it's crucial for secure crypto transactions.
Trezor Bridge® is a lightweight communication tool that enables your Trezor hardware wallet to interact directly with your web browser. Designed by SatoshiLabs, Trezor Bridge replaces outdated browser extensions and provides a more stable and secure connection between your wallet and your desktop environment.
When you use your Trezor device to manage cryptocurrencies via the Trezor Suite or compatible third-party platforms, Trezor Bridge ensures encrypted communication, smooth operation, and an uninterrupted connection across operating systems like Windows, macOS, and Linux.
Hardware wallets are the safest way to store cryptocurrencies, and Trezor is a pioneer in this space. But to utilize the wallet efficiently on a browser interface, a secure bridge is essential — and that's where Trezor Bridge® comes into play.
Here are a few key reasons why Trezor Bridge is critical:
Trezor Bridge runs in the background on your computer and acts as a translator between your browser and your hardware wallet. When you initiate a transaction or open your Trezor Suite, the browser requests device access. Trezor Bridge processes this request and communicates securely with your hardware wallet.
Without this layer, your browser would struggle to establish a direct, secure line with the USB-connected device. Trezor Bridge makes it seamless and user-friendly, ensuring the crypto interface performs optimally.
You might be wondering: “Can’t I just use WebUSB to connect my Trezor device?” Yes — but with limitations.
While WebUSB allows a direct browser-to-device connection, it lacks the full flexibility and security features that Trezor Bridge offers. Some browsers limit WebUSB support, and performance can vary. Trezor Bridge, on the other hand, offers:
Trezor officially recommends using Bridge for the best user experience.
Installing Trezor Bridge is simple and only takes a couple of minutes. Here’s how to do it:
Once installed, Trezor Bridge runs automatically in the background whenever your computer is on. There’s no need to launch it manually — just plug in your Trezor wallet and open Trezor Suite or another supported interface.
Yes, absolutely. Trezor Bridge is developed and maintained by SatoshiLabs, the original creators of the Trezor hardware wallet. The code is open-source, peer-reviewed, and updated regularly to prevent vulnerabilities.

This multi-layered approach ensures your digital assets remain secure at all times.
