Secure Connection for your Hardware Wallet
Trezor Bridge is a lightweight background service used to connect your Trezor hardware wallet to desktop applications and supported browsers.
What is Trezor Bridge?
Trezor Bridge acts as a local intermediary that forwards commands while ensuring the device's private keys remain inside the hardware. It runs quietly in the background, facilitating communication between your computer and your Trezor device.
The typical workflow uses Bridge to let apps request signatures and display account data without ever exposing your secrets to the internet or the computer itself.
Local Communication
Bridge listens on 127.0.0.1 to handle requests locally, ensuring no data leaves your machine without your explicit consent on the device.
How It Works
Trezor Bridge listens locally and manages USB detection, handshakes, and cross-platform quirks.
1. Request

Install & Update
If required for your workflow, download Bridge only from official sources. Trezor historically supplied Bridge installers for Windows, macOS, and Linux packages (DEB/RPM).
Recommendation
Trezor Suite increasingly provides the recommended experience and may replace the need for a separate Bridge install.
