Trezor Bridge — Securely connect your Trezor hardware
Trezor Bridge is the lightweight desktop connector that enables your computer and browser to communicate with your Trezor hardware wallet. It’s the secure link between your hardware and Trezor Suite or supported web apps.
Works with Trezor Model T and Trezor One. Compatible with Windows, macOS and Linux.
Why Trezor Bridge matters
Trezor Bridge acts as the secure translator between your web browser and a plugged-in Trezor device. Browsers can’t talk directly to USB hardware for security reasons; Bridge solves this safely, enabling you to use Trezor Suite or supported web apps to manage keys, sign transactions, and confirm operations on-device.
1. Install
Download the official installer from trezor.io/bridge and run it — the setup is lightweight and guided.
2. Connect
Plug your Trezor device into USB and open Trezor Suite or a supported web app. Bridge handles the secure communication layer.
3. Confirm
All critical actions (sending funds, changing settings) require pressing buttons on your Trezor device — private keys never leave the device.
Installation & Setup
Installing Trezor Bridge is intentionally simple. Follow these steps to get started:
- Go to the official Trezor Bridge page: https://trezor.io/bridge/.
- Choose the correct installer for your operating system and download the signed package.
- Run the installer and follow the on-screen instructions. On macOS, you may need to allow the installation in Security & Privacy settings.
- After installation, open your browser and navigate to Trezor Suite or a supported web app. Connect your device and follow prompts.
If the browser shows a connection error, try restarting the browser or reinstalling Bridge. For persistent issues, check the Trezor support documentation or community forums for troubleshooting steps.
Frequently asked questions
Is Trezor Bridge safe?
Yes. Trezor Bridge is maintained by the Trezor team (SatoshiLabs) and distributed as signed releases. It only acts as a local connector — private keys remain on the Trezor device and never leave it.
Do I need Bridge for Trezor Suite?
Trezor Bridge allows the browser and desktop apps to communicate with the hardware. Newer Trezor Suite desktop apps may include their own communication method, but Bridge is still commonly required for many web-based flows and legacy setups.
Where can I download Bridge?
Always download from the official source: trezor.io/bridge.
