What is Trezor Bridge?
Trezor Bridge is a lightweight software component that allows your Trezor hardware wallet to communicate securely with supported browsers and Web3 applications. It acts as a trusted gateway, encrypting data transfer between your device and the dApp while maintaining your private keys fully offline.
This bridge ensures that even while signing transactions or interacting with decentralized platforms, your sensitive data never leaves the secure environment of your hardware wallet.
Key Benefits
- Strong Encryption: Every communication between your browser and device is protected with end-to-end encryption.
- Cross-Platform Compatibility: Works across major browsers (Chrome, Firefox, Edge) and operating systems.
- Zero Exposure: Your private keys never touch your computer or the web — they stay on the hardware wallet.
- Instant Connection: Enables a frictionless user experience with secure signing and verification flows.
How It Works
Trezor Bridge runs quietly in the background. When a Web3 site requests access to your wallet, the bridge validates the request, ensures it originates from a trusted domain, and then communicates the approved instructions to your hardware device. You confirm actions directly on the Trezor screen — ensuring safety at every step.
Setup in Three Steps
- Visit trezor.io/bridge and download the installer for your operating system.
- Run the installer and restart your browser to enable connection.
- Connect your Trezor wallet, open a compatible dApp, and verify the connection prompt on your device screen.
