Trezor Bridge® — Connect Your Trezor to Web Browsers
Trezor Bridge® is an essential connectivity component that enables seamless communication between your Trezor hardware wallet and supported web browsers. Designed to provide a secure and reliable connection, Trezor Bridge allows users to manage cryptocurrencies directly through browser-based applications such as Trezor Suite (Web) and other compatible services. By acting as a secure intermediary, Trezor Bridge ensures that sensitive operations remain protected while delivering a smooth user experience.
This guide explains what Trezor Bridge is, why it’s important, how it works, and how to install and use it effectively.
What Is Trezor Bridge®?
Trezor Bridge is a lightweight background service developed by SatoshiLabs, the creators of Trezor hardware wallets. Its primary purpose is to connect your Trezor device—such as Trezor Model One or Trezor Model T—to web-based cryptocurrency interfaces.
Modern browsers have tightened security restrictions, limiting direct access to USB devices. Trezor Bridge solves this by providing a secure local connection that browsers can safely use to communicate with your hardware wallet. Once installed, it runs silently in the background and activates only when needed.
Why Trezor Bridge Is Important
Trezor Bridge plays a crucial role in maintaining both usability and security. Without it, web browsers would be unable to detect or communicate reliably with your Trezor device.
Key Benefits
Secure Communication: Ensures encrypted data transfer between your browser and Trezor device.
Browser Compatibility: Works with popular browsers such as Chrome, Firefox, Edge, and others.
Automatic Detection: Instantly recognizes your Trezor when connected via USB.
Privacy-Focused: No sensitive data or private keys are ever exposed to the computer or the internet.
How Trezor Bridge Works
Trezor Bridge operates as a local service installed on your computer. When you connect your Trezor device:
The Bridge detects the hardware wallet via USB.
It establishes a secure local channel.
Your browser-based wallet interface communicates with the device through the Bridge.
All cryptographic operations, including transaction signing, occur inside the Trezor device, not on your computer.
This design ensures that private keys never leave your hardware wallet, even when interacting with online applications.
Supported Platforms and Browsers
Trezor Bridge is compatible with major operating systems and browsers, making it accessible to a wide range of users.
Supported Operating Systems
Windows
macOS
Linux
Supported Browsers
Google Chrome
Mozilla Firefox
Microsoft Edge
