What is Trezor Bridge?
Trezor Bridge, developed by SatoshiLabs, is a lightweight software program designed to enable seamless communication between Trezor hardware wallets, the Trezor Suite application, and supported web browsers. Acting as a background service, it facilitates the secure transfer of data and commands without requiring direct user intervention after installation. This tool was essential in earlier versions of the Trezor ecosystem, ensuring that users could interact with their devices for tasks like transaction signing, firmware updates, and wallet management.
Running silently in the background—visible as 'trezord' or 'trezord-go' in system monitors—Trezor Bridge provided a stable connection layer, particularly useful for web-based interfaces before full integration into desktop apps. It supported major operating systems including Windows, macOS, and Linux, making it accessible for a wide range of users in the crypto community.
History and Purpose of Trezor Bridge
Introduced as part of the Trezor suite of tools, Trezor Bridge addressed the need for reliable device-to-computer communication in an era when hardware wallets were gaining popularity. Its primary purpose was to act as an intermediary, allowing browsers and applications to detect and interact with the Trezor device without native support. This was crucial for security, as it kept sensitive operations offline on the hardware while enabling user-friendly interfaces.
Over the years, Trezor Bridge evolved to support new models like Trezor Model T and Safe 3, handling USB connections and ensuring compatibility with various crypto protocols. It played a key role in maintaining the open-source ethos of Trezor, with its code available for community review on GitHub. However, as technology advanced, the need for a standalone bridge diminished with the rise of integrated solutions.
Key Features (Historical)
- Background operation for minimal user disruption.
- Cross-platform compatibility (Windows, macOS, Linux).
- Secure data relay between device and software.
- Status check via local URL[](http://127.0.0.1:21325/status/).
- Easy installation via official downloads or package managers like Homebrew.
Deprecation and Removal of Standalone Trezor Bridge
In recent years, SatoshiLabs announced the deprecation of the standalone Trezor Bridge to streamline the user experience and enhance security. As of 2025, maintaining the separate program is no longer recommended, as it may interfere with newer versions of Trezor Suite and future updates. The decision stems from the integration of bridge functionality directly into Trezor Suite, reducing redundancy and potential conflicts.
This move aligns with industry trends toward consolidated software ecosystems, minimizing the attack surface and simplifying maintenance for users. If you have the standalone version installed, it's advised to uninstall it promptly to ensure smooth operation with the latest Trezor tools.
How to Uninstall Trezor Bridge
Uninstalling Trezor Bridge is straightforward and varies by operating system. Follow these steps to remove it safely:
- macOS: Open Finder, navigate to Applications > Utilities > TREZOR Bridge. Double-click 'uninstall.pkg' and follow the installer prompts.
- Windows: In File Explorer, go to Program Files > TREZOR Bridge. Run 'uninstall.exe' to automatically remove the program.
- Linux: Use the terminal command: sudo apt remove trezor-bridge. Verify removal with: sudo apt list --installed | grep trezor-bridge (should return nothing).
After uninstallation, check the status page[](http://127.0.0.1:21325/status/); it should no longer load. Restart your computer if necessary, and proceed to use Trezor Suite for all interactions.
Alternatives: Transition to Trezor Suite
With Trezor Bridge deprecated, the primary alternative is Trezor Suite, which now incorporates the necessary communication features natively. This all-in-one desktop and web app handles device connections, asset management, trading, and staking without needing a separate bridge. For web-based access, Trezor Suite Web uses WebUSB in compatible browsers like Chrome, offering quick setup without downloads.
Upgrading to Trezor Suite ensures compatibility with the latest firmware and security protocols, providing a more integrated and user-friendly experience. Mobile users can leverage Trezor Suite Lite for on-the-go monitoring, further eliminating the need for legacy tools.
