Trezor Bridge is the official communication layer between your computer and your Trezor hardware wallet. This Trezor Bridge guide explains how to download Trezor Bridge, install Trezor Bridge, use Trezor Bridge with Trezor Suite, and maintain secure connections to your Trezor wallet.
Trezor Bridge acts as a secure communication service between your browser or Trezor Suite and your Trezor device. When you plug in your Trezor, Trezor Bridge handles encrypted messages to and from the wallet. This ensures that your private keys never leave your device. Trezor Bridge runs locally, minimizing security risks. The Trezor Bridge process starts automatically when your computer boots, ensuring your Trezor Suite always detects your device without delay.
Installing Trezor Bridge is a vital step in every Trezor setup. Without Trezor Bridge, Trezor Suite and supported browsers cannot communicate with the hardware wallet. That’s why the official Trezor Bridge package is included in the official Trezor Getting Started flow.
Follow these steps to install Trezor Bridge securely:
If you already have Trezor Bridge installed, it will update automatically when new versions are released. This ensures your Trezor Bridge is always compatible with Trezor Suite and browser extensions. Manual updates can also be done through the same Trezor Bridge installer package.
The Trezor Bridge service is critical for the reliable use of Trezor devices. Using Trezor Bridge, your Trezor Suite can seamlessly recognize your device without plugins or deprecated browser APIs. Trezor Bridge improves both speed and security of data transfer. Because Trezor Bridge communicates directly with your local system, it removes the need for WebUSB in unsupported browsers and provides consistent connectivity for all operating systems.
Every time you open Trezor Suite, Trezor Bridge ensures that communication is authenticated and verified. You’ll see device prompts confirming operations. The Trezor Bridge process runs quietly in the background, securing the communication pipeline between your software and hardware.
If your Trezor Suite cannot detect your device even after installing Trezor Bridge, try the following troubleshooting steps:
If the issue persists, consult the official Trezor support documentation. They maintain updated help pages dedicated to Trezor Bridge, connection issues, and USB troubleshooting. The Trezor Bridge log file, accessible in system directories, can also be helpful for advanced debugging.
