Communication Backbone Between Your Device and Browser

1️⃣ Secure Device Connection

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.

2️⃣ Encrypted Communication

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.

3️⃣ Device Authentication

Trezor Bridge ensures that login and transaction approval require physical device confirmation. Even if malware infects a computer, actions cannot occur without hardware validation.
