🔍 Technical Details

Trezor Bridge operates as a local web server that communicates with both the Trezor device and web applications through a standardized API. This architecture ensures that private keys never leave the hardware wallet, maintaining the highest level of security for your digital assets.

The application uses WebUSB technology for browsers that support it, falling back to the U2F protocol when necessary. This dual-approach compatibility ensures broad browser support while maintaining security standards.
