Trezor Bridge — Securely connect your Trezor hardware wallet to desktop browsers
Trezor Bridge is the desktop connector that allows your Trezor device to communicate securely with web apps and wallets. This page provides a clear overview of what Bridge does, compatibility notes, security features, and where to get help.
About Trezor Bridge
Trezor Bridge acts as a local communication daemon that securely forwards requests from compatible web applications to your Trezor hardware wallet connected via USB or WebUSB. It is primarily intended to improve compatibility and user experience across browsers and platforms.
Core principles
- Security-first: Keys never leave the Trezor device; Bridge only transports encrypted messages for signing.
- User control: All signing requests require physical confirmation on the device.
- Compatibility: Supports modern browsers and wallet UIs that integrate Trezor devices.
Quick facts
Latest stable Bridge releases usually include compatibility updates and security patches; keep Bridge updated from official sources.
