Trezor Bridge — Install & Configure

The official Trezor Bridge app runs on your computer and bridges the USB connection between your Trezor device and Trezor Suite or compatible web applications. It ensures cross-platform compatibility and smooth connectivity for transaction signing workflows.

Download & install

Visit trezor.io/bridge, choose your operating system, and run the installer. After installation, restart your browser and reconnect your Trezor device. The Bridge runs in the background and listens on localhost.

How Bridge keeps communication safe

Bridge only forwards requests from local apps to the USB device. It does not access or store your private keys. All signing operations occur on the Trezor hardware itself, which is the critical security boundary.

Advanced notes

If you use custom browser settings or corporate security software, ensure local processes are allowed to communicate with Bridge. Power users can check Bridge logs to diagnose connectivity issues.

Security & Best Practices

Always download Bridge from trezor.io, verify checksums if available, and confirm transaction details on the device screen before approving. Keep Suite, Bridge, and firmware up to date.
