Trezor Bridge Download

Securely connect your Trezor hardware wallet to supported browsers and apps

What is Trezor Bridge?

Trezor Bridge is a lightweight, secure background application developed by SatoshiLabs. It acts as a communication layer between your Trezor hardware wallet and compatible browsers or desktop applications. It enables seamless interaction with your device, allowing secure transaction signing, cryptocurrency management, and integration with web-based services such as Trezor Suite Web.

Without Trezor Bridge, modern web browsers may not be able to directly communicate with your hardware wallet due to USB access restrictions. Trezor Bridge overcomes this by running a secure local service that exposes a safe API accessible only from your computer.

Bridge is essential for browser-based usage of your Trezor device. If you're using the desktop version of Trezor Suite, the Bridge is not required.
