Trezor Bridge is an essential software component that enables secure communication between a Trezor hardware wallet and browser-based applications. It acts as a trusted background service, allowing websites and web interfaces to interact with your Trezor device without exposing sensitive data.
Designed with security and reliability in mind, Trezor Bridge ensures that all cryptographic operations remain inside the hardware wallet while providing smooth connectivity for supported platforms.
Trezor Bridge is a lightweight application installed on your computer that serves as a connection layer between your web browser and your Trezor hardware wallet. Since browsers cannot securely communicate with USB devices on their own, Trezor Bridge fills this gap.
Once installed, Trezor Bridge runs automatically in the background and activates only when a compatible website or web wallet attempts to access the Trezor device.
Security is the foundation of the Trezor ecosystem. Trezor Bridge ensures that browser-based wallet access remains secure without relying on outdated or risky browser extensions.
Trezor Bridge functions as a local background service on your operating system. When a supported web application requests access to your Trezor wallet, the request is routed through the Bridge.
At no point does Trezor Bridge store private keys or recovery data.
Trezor Bridge is primarily required when using browser-based wallet interfaces rather than the Trezor Suite desktop application.
You may need Trezor Bridge if:
Although both are part of the Trezor ecosystem, Trezor Bridge and Trezor Suite serve different purposes.
Note: Users who rely solely on Trezor Suite Desktop may not need Trezor Bridge installed.
Trezor Bridge is designed with strict security principles to ensure user safety.
Trezor Bridge supports major operating systems to ensure broad compatibility.
Once installed, it runs quietly in the background without interrupting your workflow.
Some users may experience connectivity issues. Most problems are easy to resolve:
Trezor Bridge respects user privacy. It does not track activity, collect analytics, or send data to external servers. All communication remains local between your device and your browser.
This privacy-first approach makes Trezor Bridge suitable for users who value anonymity and control.
To ensure safe usage:
With the rise of Trezor Suite Desktop, many users no longer require Trezor Bridge. However, it remains important for specific workflows involving browser-based wallets and legacy platforms.
For users who rely on web interfaces, Trezor Bridge continues to be a reliable and secure solution.
Trezor Bridge is ideal for:
Trezor Bridge is a vital component that enables secure communication between Trezor hardware wallets and browser-based applications. By acting as a trusted background service, it ensures smooth connectivity without compromising the security of private keys.
When used correctly and installed from official sources, Trezor Bridge provides a safe, efficient, and privacy-respecting solution for browser-based Trezor access.
