A concise presentation that explains what Trezor Bridge was, how it connects your hardware wallet to web apps, why Trezor moved to Trezor Suite, and where to find official resources.
Trezor Bridge is a background service originally developed by SatoshiLabs to provide a secure communication channel between a Trezor hardware wallet and browser-based wallet interfaces or web apps. It acted as a small local HTTP bridge that allowed web pages to talk to the USB-connected device without exposing low-level USB APIs to websites.
Key: standalone Trezor Bridge has been deprecated in favor of using the Trezor Suite and newer transport methods recommended by Trezor. :contentReference[oaicite:0]{index=0}
Browsers historically limited direct access to USB HID devices. Trezor Bridge solved this by running a small local service that handled the USB/HID level communication and exposed a secure local endpoint that trusted Trezor web apps could use. This minimized the browser surface that needed low-level access while keeping cryptographic operations on the hardware device.
For users of web-based wallet pages or browser integrations, Bridge removed many compatibility problems across operating systems and browsers by centralizing transport logic in one maintained component.
Trezor has announced the deprecation and removal of the standalone Trezor Bridge binary. Users are encouraged to move to the official Trezor Suite desktop or web app that includes supported transport layers and updated security practices. If you still have a standalone Bridge installed, Trezor’s guides explain uninstall steps and migration advice. :contentReference[oaicite:1]{index=1}
Trezor Suite offers an integrated, verified application experience (desktop app or web) that reduces the need for standalone auxiliary services. The Suite is the primary, supported way to interact with Trezor devices going forward. :contentReference[oaicite:2]{index=2}
Always update your Trezor firmware and the official Suite app. Security fixes and transport updates (e.g., nodeBridge, Suite integration) are released periodically and are the safest route for device management. For troubleshooting and device visibility, Trezor support provides step-by-step advice. :contentReference[oaicite:3]{index=3}
Download Trezor Suite or Bridge-related components from the official trezor.io domain or the Trezor GitHub organization. Avoid third-party binaries and unofficial mirrors.
Trezor’s code and integration tools are open-source and hosted under the Trezor/SatoshiLabs GitHub organization. Developers building wallet integrations should consult the official developer docs and partner portal for proper transport and API usage. :contentReference[oaicite:4]{index=4}
