Trezor Bridge was created to help connect Trezor hardware wallets with compatible browsers and wallet software. Learn how the connection system works today and why current Trezor Suite users generally do not need the old standalone Bridge application.
Open Trezor SuiteTrezor Bridge was a background application designed to facilitate communication between a Trezor hardware wallet, Trezor Suite and supported web browsers. It helped wallet software communicate with the physical Trezor device connected to a computer.
The standalone version of Trezor Bridge is now deprecated. Trezor has moved to a newer connection architecture, with nodeBridge incorporated into Trezor Suite. This means new users should normally start with the current Trezor Suite application rather than searching for an old standalone Bridge installer.
Bridge technology was designed to help wallet software communicate with a connected Trezor hardware device.
The original Bridge helped supported browsers interact with Trezor hardware when using compatible wallet interfaces.
Current Trezor Suite uses the newer nodeBridge architecture instead of requiring the deprecated standalone Bridge installation.
Trezor officially recommends uninstalling the standalone Bridge application because keeping an older installation may interfere with future Trezor device connections. Current Trezor Suite users should use the connection system included with the latest Suite releases.
Earlier Trezor wallet workflows required a separate background application to establish communication between the hardware wallet and browser-based software. Trezor Bridge provided that communication layer without requiring users to interact with it during normal use.
New users should download the current Trezor Suite application from the official Trezor website and follow the setup instructions. Trezor currently recommends the installed Suite application for desktop users because it provides enhanced functionality and privacy.
Get the current Trezor Suite application from the official Trezor website.
Connect your Trezor hardware wallet using a suitable USB data cable and follow the instructions.
Follow the prompts inside Trezor Suite to initialize and manage your Trezor device.
Important: If Trezor Suite does not detect your device, check the USB cable, device firmware and supported operating-system requirements before looking for old Bridge software.
The Trezor Suite desktop application is the preferred option for many desktop users. It provides a complete interface for connecting your Trezor hardware wallet and managing supported crypto assets.
Trezor also provides a web application that can run in supported Chromium-based browsers. The web version communicates with the Trezor device through the current supported connection architecture.
When using Trezor Suite in a browser, verify the address carefully before connecting your hardware wallet. Avoid unofficial websites, sponsored phishing pages and unexpected wallet connection requests.
Security is especially important when installing wallet software or connecting a hardware wallet. Only use software obtained from official Trezor sources.
Because standalone Trezor Bridge is deprecated, searching for an old installer from an unknown website can create unnecessary security risks. Use the current Trezor Suite software instead.
Never type your wallet backup words into a website, browser pop-up or unexpected application. Trezor's current guidance says wallet backup words should be entered only on the Trezor device when required.
Download Trezor Suite directly from Trezor's official website and follow the company's verification instructions when appropriate. This helps reduce the risk of downloading modified or fraudulent software.
Although the standalone application is deprecated, understanding Trezor Bridge can be useful when troubleshooting older Trezor setups. Users may still find the old Bridge process running on a computer after installing it in the past.
If an older installation is causing connection problems, Trezor provides instructions for removing the standalone Bridge from Windows, macOS and Linux. Current users should then rely on the supported Trezor Suite connection architecture.
Standalone Trezor Bridge is no longer the recommended installation. Download the current Trezor Suite application and follow the official setup instructions for your Trezor hardware wallet.
