Trézór Bridge®™ | Smooth, Safe, and Encrypted Crypto Connectivity
Trezor Bridge® — Secure Connection Between Your Browser and Trezor Wallet
Trezor Bridge® is an official communication service developed by Trezor that enables secure interaction between your Trezor hardware wallet and supported web browsers. It acts as a trusted background component that allows web-based wallet interfaces—such as Trezor Suite Web—to detect and communicate with your Trezor device safely.
If you are accessing your wallet through a browser instead of the desktop app, Trezor Bridge ensures that all data exchanges remain secure and verified.
What Is Trezor Bridge?
Trezor Bridge is a lightweight software service installed on your computer that creates a secure link between your web browser and your Trezor hardware wallet. Because browsers cannot directly communicate with USB hardware securely, Trezor Bridge fills that gap.
It does not store private keys, recovery seeds, or personal data. Its sole purpose is to facilitate safe communication.
Why Trezor Bridge Is Important
Without Trezor Bridge, your browser would not be able to recognize or interact with your Trezor device. The bridge ensures:
Secure device detection in browsers
Encrypted communication channels
Protection against malicious browser scripts
Verified access for official Trezor web applications
It is especially useful when using Trezor Suite Web instead of the desktop application.
