Enable secure communication between your Trezor hardware wallet and your web browser
Trezor Bridge is a lightweight software component developed by SatoshiLabs that allows communication between your Trezor hardware wallet and supported web applications like Trezor Suite Web. Since modern browsers have limitations on direct USB communication, Trezor Bridge provides a secure, local interface for browser apps to access your wallet without exposing your data to the internet.
Running as a local background service, Trezor Bridge acts as a secure communication bridge between your Trezor device and your browser. Without it, your browser may not be able to recognize or interact with the Trezor device, especially on operating systems that restrict WebUSB capabilities.
Trezor Bridge is essential for anyone using Trezor devices on the web, offering stability, improved connectivity, and compatibility across multiple browsers and operating systems.
Select your operating system to download the latest official version of Trezor Bridge:
Note: Always download Trezor Bridge from the official website to avoid compromised versions or malware. Verify the checksum if possible.
Follow the steps below to install Trezor Bridge on your system:
You can confirm that Trezor Bridge is running by visiting http://127.0.0.1:21325/status/ in your browser. A status JSON will be shown if it’s active.
Trezor Bridge is designed with your privacy and security in mind. It only communicates with your local machine and does not transmit any private information over the internet. All critical operations—such as signing transactions or exporting keys—must be confirmed directly on your Trezor device.
Additionally, Trezor Bridge is open-source. This transparency ensures that anyone can review the codebase and verify that no malicious actions are being taken. The software is signed by SatoshiLabs and regularly maintained.
Best of all, the Trezor device itself never exposes your private keys to the host computer—Trezor Bridge only facilitates communication, not cryptographic actions.
No. The desktop version of Trezor Suite connects directly to your hardware wallet without requiring Trezor Bridge. The Bridge is primarily needed for the web version.
Yes. It’s open-source, maintained by SatoshiLabs, and runs only on your local machine. It cannot send data outside unless your machine is already compromised.
Make sure Bridge is installed and running. Also try restarting your browser or using a different USB cable. Check http://127.0.0.1:21325/status/ to confirm it’s active.
Trezor Bridge works with Chrome, Firefox, Brave, and Edge. Safari support is limited due to USB restrictions.
Yes, you can remove it via your system’s app manager. Just note that browser access to your Trezor will stop working without it (unless you use the desktop app).
Trezor Bridge may prompt you to update when a new version is available. Always install updates promptly to ensure compatibility and security.
