The essential connection layer that allows your Trezor device and browser to communicate safely.
Trezor Bridge is a lightweight, secure application that runs in the background and enables communication between your Trezor hardware wallet and wallet interfaces on your computer, such as browser-based apps or Trezor Suite Web. Without Trezor Bridge, your web browser cannot interact directly with your hardware device due to privacy and security restrictions.
Trezor Bridge ensures smooth and safe communication, allowing you to manage your cryptocurrency, verify transactions, and configure wallet settings—while keeping your private keys safely inside the Trezor device at all times.
Modern browsers block direct USB communication with hardware wallets for security reasons. Trezor Bridge was created to solve this problem by acting as a trusted communication channel. It securely connects your device and the application you are using—without ever exposing sensitive data.
Trezor Bridge runs automatically in the background once installed. It establishes a secure, encrypted communication path between your wallet interface and the hardware device.
The most important part: Trezor Bridge never handles private keys. All key-related operations occur inside your Trezor’s secure environment.
