How it works

1. Install Bridge
Download and install the Bridge on your desktop. It runs in the background and exposes a local interface for web apps.
2. Connect your Trezor
Plug your Trezor into a USB port and unlock it with your PIN. The Bridge will detect the device automatically.
3. Use with wallets
Open your web wallet; it will communicate with the Bridge to sign transactions while your private keys remain on the device.

Headless operation, logs for diagnostics, and options for advanced configuration.

Frequently asked questions

Is Bridge required to use my Trezor?

For most web-based wallet integrations, Bridge or an equivalent communication layer is required to enable secure communication between the browser and your Trezor device.

How do I verify the download?

After downloading, compare the SHA256 checksum and verify the PGP signature included with the release. Instructions are linked on the release page.

Does Bridge run in the cloud?

No — Bridge runs locally on your computer and does not relay device data through remote servers.

I see an update available. Should I install it?

Keeping Bridge updated ensures you have the latest security improvements. Review release notes before updating if you require specific compatibility.
