Trezor Bridge

Invisible. Secure. Always-on — the connection your Trezor deserves.

Trezor Bridge is a minimal, secure service that enables encrypted communication between your Trezor hardware wallet and Trezor Suite. Install it once and let the Bridge manage USB connections, signatures, and firmware interactions without exposing your keys or workflows to the web browser.

One-time install
Install the Bridge once and it runs silently. Auto-updates keep compatibility current with Suite and firmware releases.
Privacy-first
No telemetry. No data collection. The Bridge only exists to connect your device securely to Suite on your machine.
Lightweight
Tiny footprint, low memory overhead — designed for fast startup and consistent performance.
Cross-platform
Windows, macOS, Linux — the Bridge provides a common, dependable layer across desktop environments.
Device discovery: The Bridge detects a connected Trezor and establishes an encrypted session with Suite.
Secure commands: Transaction signing and firmware commands are routed through the Bridge, keeping private keys on the device.
Automatic updates: Bridge checks for updates and applies them safely; you stay compatible without manual installs.
Minimal exposure: Browser plugins and web USB are avoided — the Bridge is the focused, auditable middle layer.
Why use Bridge?
It isolates hardware communication from web layers, reduces attack surface, and standardizes device access for Suite.
Open source
Code is public and auditable — community reviews help maintain trust and security.
No background noise
Runs quietly and efficiently so your computer remains responsive; designed for real users.
Fast recovery
If connection issues occur, Bridge offers clear logs and quick guidance to re-establish secure links.
