Trezor Bridge is a lightweight, background application developed by SatoshiLabs that enables your Trezor hardware wallet to communicate securely with your computer’s browser—ensuring your private keys never leave the device.
Because browser extensions have been deprecated for connecting your Trezor wallet, Trezor Bridge acts as the encrypted conduit between your device and apps like Trezor Suite or Web3 platforms—making crypto management both secure and seamless.:contentReference[oaicite:1]{index=1}
You can download Trezor Bridge from the official site at **trezor.io/start**. Select your OS (Windows, macOS, Linux), install the executable, restart your browser, then connect your Trezor device. The Bridge then runs quietly in the background to enable hardware interaction.:contentReference[oaicite:2]{index=2}
The latest stable release is **Trezor Bridge version 24.9.2**, delivering enhanced performance, browser compatibility, and improved security patches. Users are advised to upgrade to ensure maximum protection.:contentReference[oaicite:3]{index=3}
Trezor Bridge is fully compatible with modern browsers (Chrome, Firefox, Edge, Brave) and operating systems (Windows 10/11, macOS 10.15+, popular Linux distros). It's especially required if your setup lacks full WebUSB support.:contentReference[oaicite:4]{index=4}
Although the desktop version of Trezor Suite includes an embedded Bridge, web-based access at **suite.trezor.io** typically requires the standalone Trezor Bridge. Without it, your device may not be detected in-browser.:contentReference[oaicite:5]{index=5}
Trezor Bridge ensures encrypted, device-only communication. It isolates private keys, enforces firmware integrity checks, and protects against man-in-the-middle attacks. All transaction approvals happen physically on the Trezor device itself.:contentReference[oaicite:6]{index=6}
If you see “Trezor Bridge not running” errors, ensure you’ve installed it correctly, restart your browser, or restart your device. Remove old Trezor Chrome extensions and verify Trezor Suite isn’t open (which may auto-launch the bridge).:contentReference[oaicite:7]{index=7}
Community threads suggest that Trezor Bridge is safe to download from official sources, and even a compromised Bridge cannot sign transactions without your physical approval on-device.:contentReference[oaicite:8]{index=8}
If your browser and OS fully support WebUSB, Trezor Bridge may not be required. However, many older configurations still rely on it for stable and secure communication via the web interface.:contentReference[oaicite:9]{index=9}
Always download Trezor Bridge directly from trezor.io or Trezor Suite to avoid phishing risks. Do not trust third-party mirror links, especially those prompted via dApps asking for Bridge installation.:contentReference[oaicite:10]{index=10}
For anyone using a Trezor hardware wallet, Trezor Bridge is an essential component—facilitating encrypted communication, browser recognition, and interaction with Trezor Suite or third-party dApps, while maintaining your privacy and control at all times.
