Introduction
Trezor Bridge is a small background service that enabled secure communication between your computer and a Trezor hardware wallet. Trezor has been evolving its connectivity model and now encourages users toward Trezor Suite for a simpler, integrated experience.
What is Trezor Bridge?
Bridge is a lightweight local application that translates USB and browser calls into commands your Trezor device understands. It allowed older browsers and OS setups to interact with the device without requiring browser plugins.
Getting started — step by step
- Check the official Trezor guidance to confirm whether standalone Bridge is necessary for your OS.
- Download only from trezor.io or official GitHub releases.
- Install (follow OS prompts). Uninstall older Bridge installs if recommended.
- Connect your Trezor, open Trezor Suite or a supported app, and complete hardware confirmations.
- Always verify transaction details on the device before approving.
Core features
Device communication
Reliable USB handling between host and device.
Cross-platform
Worked on Windows, macOS and many Linux distros.
Small footprint
Runs in background with minimal resources.
Security model
Private keys remain on the hardware device — Bridge only passes commands.
Trust & safety
Bridge does not have access to your private keys. Still, downloads must come from official sources and, when possible, verify signatures. Trezor now recommends Trezor Suite for most users to reduce compatibility issues.
