What is Trezor Bridge?
Trezor Bridge is a background service that enables communication between your Trezor hardware wallet and supported web applications. When you use your Trezor device with web wallets or browser-based interfaces like Trezor Suite Web, the Bridge acts as a secure communication link between your device and your browser.
Most modern browsers (except Chrome with WebUSB) require Trezor Bridge for a seamless and secure user experience. It ensures your device can sign transactions, access balances, and interact with DApps — all while keeping your private keys offline.
Why Do You Need Trezor Bridge?
Without Trezor Bridge, your browser cannot detect or communicate with your Trezor device. While some browsers support WebUSB, compatibility is not universal, and security may vary. Bridge guarantees consistent, secure communication across all major operating systems.
Key use cases include:
- Logging into Trezor Suite Web
- Signing transactions on supported exchanges and platforms
- Accessing decentralized applications (DApps)
- Performing firmware updates and device initialization
