Transparent connectivity
Bridge creates a local connection on your machine so websites can interact with the device without exposing keys to the internet.
What is Trezor Bridge®?Secure
Trezor Bridge® is a lightweight, secure gateway that connects your Trezor hardware wallet to desktop and web applications. It forwards encrypted commands between the device and your browser, enabling wallet management, coin discovery, and transaction signing while keeping your private keys safely stored on the hardware device.
Cross-platform
Available for Windows, macOS, and Linux — compatible with the most popular browsers and wallet interfaces.
Automatic updates
Small, secure updates keep Bridge current with the latest device protocols and security patches.
Minimal footprint
Designed to be unobtrusive; it runs only when needed and uses minimal system resources.
Install & Setup
Installing Bridge is straightforward. Download the installer suitable for your operating system, run it, and follow on-screen prompts. Once installed, connect your Trezor device and open your preferred wallet web app. Bridge will appear as the local connector and will prompt you to authorize access when an app requests device interaction.
Quick commands: If you ever need to restart the service: trezor-bridge --restart (this is a conceptual example — your actual commands or UI may differ by platform).
Security & Privacy
Security is the core mission. Bridge only relays messages — all critical operations, like key generation and transaction signing, happen on the Trezor device. Bridge never stores private keys, and it uses secure channels between your browser and the device. Always verify transaction details on the device screen before confirming: the device display is the single source of truth.
Best practices: keep firmware up to date, download Bridge from official sources, protect your recovery seed, and avoid using untrusted machines for large transactions.
FAQ
Do I need Bridge to use my Trezor?
In most desktop and browser scenarios, yes — Bridge simplifies and secures the connection. Some native apps or command-line tools can talk directly to the device, but Bridge provides the best cross-application compatibility.
Is Bridge safe to run?
Yes. Bridge is built with a minimal attack surface and acts as a local relay. The hardware device performs the sensitive operations, and Bridge does not expose cryptographic secrets.
What if Bridge won’t detect my device?
Check cable and port, ensure your OS has the latest updates, restart the bridge service, or reinstall the latest Bridge package. If problems persist, consult official support channels and include log output for faster troubleshooting.
