Trezor Bridge is software that enables communication between a Trezor hardware wallet and compatible web applications. It works in the background to help supported browsers and applications communicate with your connected Trezor device.
Trezor Bridge acts as a communication layer between your computer and Trezor hardware wallet. When installed and running correctly, it can allow compatible Trezor services and applications to detect and communicate with the connected device.
Connect your Trezor hardware wallet to your computer.
Install the current version of Trezor Bridge from an official Trezor source when required.
Allow the software to run in the background.
Open a compatible Trezor application or service.
Follow the on-screen instructions to connect and authorize your device.
Whether you need Trezor Bridge depends on the Trezor product and application you are using. Modern Trezor Suite installations may handle device communication without requiring users to manually manage Bridge in every situation.
If a compatible application cannot detect your Trezor device, checking whether the appropriate official communication software is installed and running can be a useful troubleshooting step.
Download Trezor Bridge only from the official Trezor website. Avoid unofficial installers, browser pop-ups, and links from unknown sources.
Never enter your recovery seed, wallet backup, or PIN into a website claiming that Trezor Bridge needs it. Trezor Bridge is communication software and should not require you to disclose your recovery phrase.
If your Trezor device is not detected:
Check the USB connection.
Try another compatible USB port or cable.
Restart the Trezor application.
Confirm that the official Trezor software is up to date.
Check whether Trezor Bridge is installed and running if your application requires it.
Restart your computer if the connection continues to fail.
Using official Trezor software and carefully verifying transaction details on your hardware wallet can help maintain a secure wallet-management setup.
