Communication Backbone Between Your Device and Browser
Trezor Bridge establishes a protected communication channel between your Trezor hardware wallet and your computer. It replaces outdated browser plugins with a lightweight background service.
All data exchanged between your browser wallet interface and the hardware device is encrypted. Private keys never leave the device — Bridge only transmits signed instructions.
Trezor Bridge ensures that login and transaction approval require physical device confirmation. Even if malware infects a computer, actions cannot occur without hardware validation.
Bridge helps verify firmware authenticity when updates occur. This prevents malicious software from interacting with your wallet. The system maintains a trust chain between hardware, firmware, and user interface.
