Trezor Bridge
A secure communication layer between your Trezor hardware wallet and your computer apps.
About Trezor Bridge
Trezor Bridge is a small background application that historically allowed a Trezor hardware wallet to communicate with web browsers and desktop apps (notably Trezor Suite). It acts as a bridge between a USB-connected Trezor device and browser-based wallet interfaces, routing commands securely so that transactions can be signed on-device while keeping private keys safe inside the hardware wallet.
Why a bridge?
Browsers do not always expose consistent low-level USB interfaces and security models across platforms. Trezor Bridge fills that gap: it provides a stable, cross-platform interface that web apps and desktop apps can call, while minimizing direct browser access to the hardware. Users experience reliable device detection and secure signing without exposing sensitive operations to the web page itself.
Important: migration to Trezor Suite
Note: Trezor has deprecated the standalone Trezor Bridge and now integrates the required connectivity into the official Trezor Suite. If you still have a standalone Bridge installed, Trezor recommends uninstalling it and using the Trezor Suite app or the official web workflows provided by Trezor for the smoothest, most secure experience.
Install & uninstall (high level)
Historically the typical steps were: download the Bridge installer for your OS, run the installer, and grant any system permissions requested. Uninstalling (if present) follows standard OS procedures: uninstall executable on Windows, run the provided uninstall package on macOS, or remove the package on Linux. If you're unsure whether Bridge is needed, check for "trezord" / "trezord-go" processes in your system monitor and consult Trezor's official guidance.
Safety & best practices
Always download software from the official Trezor website or Trezor Suite distribution channels. Keep firmware and desktop apps up to date, verify installer signatures when possible, and never share recovery seeds or private keys. When connecting your Trezor to any app, confirm the exact transaction details on the hardware device display before approving.
FAQ
Do I still need Trezor Bridge?
For most users the Trezor Suite now handles connectivity directly; standalone Bridge is deprecated. Use Trezor Suite or follow the official guide if you must remove Bridge from your system.
Is Bridge safe?
Bridge itself was designed to be a minimal, transparent relay—security depends on using official builds and keeping software up to date.
