Overview. Trezor Bridge historically served as an intermediary application that allowed web browsers and Trezor hardware wallets to communicate securely over USB. It provided a local bridge so web apps could discover and interact with a Trezor device on desktop systems, enabling secure signing and interaction with crypto applications.
How it worked
Trezor Bridge ran on the user’s computer and exposed a local endpoint that browser-based wallet interfaces used to reach the connected Trezor device. This helped bypass certain browser USB restrictions and simplified device connectivity for desktop users. Bridge was complementary to the Trezor Suite desktop and web apps, offering a compatibility layer for legacy flows.
Recent changes & guidance
Important: Trezor has been moving functionality into Trezor Suite and modern web flows. The vendor has published guidance recommending users migrate to Trezor Suite or follow official instructions, and that standalone Bridge may be deprecated or removed in favor of integrated or WebUSB-based approaches. For the most accurate, up-to-date guidance and downloads always use the official Trezor website (linked on this page). :contentReference[oaicite:1]{index=1}
For users setting up a Trezor device today, the recommended path is to use the official Trezor Suite desktop app or the Trezor web app; those pages host current installers, checksums, and verification instructions to ensure you install authentic software. Always verify that you are on trezor.io and avoid downloading Bridge or Suite from third-party mirrors. :contentReference[oaicite:2]{index=2}
Security notes
Because Trezor devices secure private keys offline, the integrity of the software you use to interface with the device matters. Only download and verify software from the official Trezor website; check checksums or signatures where provided; and never share recovery seeds or allow remote access to your machine while initializing. If you’re unsure about a download or an unexpected prompt to install Bridge, consult the official support guides first. :contentReference[oaicite:3]{index=3}
