Trezor Bridge
What is Trezor Bridge?
Trezor Bridge is a lightweight application that runs on your computer to create a secure local connection between your Trezor hardware wallet and applications such as Trezor Suite, browser-based wallets, and developer tools. Trezor Bridge handles USB communication, ensures that the Trezor device remains isolated for security, and provides a stable channel for signing transactions. Using Trezor Bridge helps keep your keys safe while enabling smooth interaction with the leading Trezor Suite software and web integrations.
Secure & Local by Design
Trezor Bridge keeps communication local — it never sends private keys over the internet. The bridge only facilitates device discovery and transaction signing, making Trezor Bridge a critical component of the secure Trezor hardware wallet workflow.
Easy Installation & Cross-Platform
Install Trezor Bridge on Windows, macOS, and Linux. The installer is small, fast, and easy to run. Once installed, Trezor Bridge runs in the background and starts automatically when you connect a Trezor device.
Trusted by Developers and Users
Developers use Trezor Bridge to integrate hardware wallet support into web apps and developer tools. End users rely on Trezor Bridge to connect their hardware wallet to the Trezor Suite app for secure crypto management.
Download & Install Trezor Bridge
Choose the right package for your operating system. Download Trezor Bridge from the official source to ensure authenticity and security.
Quick Setup Steps
- Download Trezor Bridge (Windows, macOS, Linux).
- Install the package and allow the bridge to run in the background.
- Connect your Trezor hardware wallet with USB/USB-C and open Trezor Suite or the supported web app.
- Authorize and sign transactions directly on your Trezor device — keys never leave the device.
Security & Privacy
Trezor Bridge is intentionally minimal: it performs device discovery and message transport between your Trezor device and authorized applications. The bridge is designed to avoid network exposure of sensitive material — Trezor Bridge does not transmit private keys or seed phrases. Always download Trezor Bridge from official channels and verify digital signatures when available to ensure you’re running authentic software.
Troubleshooting
If Trezor Bridge does not detect your device, try these steps:
- Reconnect the USB cable and try a different port.
- Make sure Trezor Bridge is installed and running (check system tray or background processes).
- Restart Trezor Suite or your browser tab, then reconnect the device.
- Update to the latest version of Trezor Bridge and the Trezor Suite app.
Developer Notes
Developers integrating hardware wallet support into web apps can rely on Trezor Bridge for consistent USB communication. The bridge exposes a local API for authorized origins to interact with the device. Always follow secure integration guidelines and request user consent before initiating any signing operations.
