Meet the bridge
to self-custody.

Trezor Bridge is a small communication layer that lets compatible software in your browser talk to a Trezor hardware wallet.

A hardware wallet keeps the private keys used to authorize transactions isolated from an internet-connected computer. To use those keys safely, an application still needs a way to request information from the device and send it actions to review. Bridge supports that handoff between a browser and your connected Trezor.

Think of it as a translator—not a wallet, exchange, or place where your assets are stored. It helps a supported interface discover the device and pass requests along. Your Trezor remains the important checkpoint: sensitive actions should be checked and approved on the hardware wallet itself, not trusted just because a webpage says so.

The broader Trezor experience has evolved over time. Trezor Suite is the official application for managing a device, viewing supported accounts, and carrying out common wallet tasks. Some compatible browser-based services may also rely on Bridge or related connection components. What you need depends on your device, operating system, browser, and the app you are using.

Because software and compatibility can change, an older tutorial may no longer describe the right installation path. Prefer current documentation over archived forum posts, and never treat a connection prompt as proof that a page is trustworthy. Bridge provides a channel; it does not certify the intentions of every site that asks to use it.

In practical terms, Bridge is useful when an application needs a recognized way to reach your hardware wallet. If you use Trezor Suite, begin with the official Suite instructions. If you are connecting to a third-party service, confirm that the service is reputable and understand what action it is requesting before granting access or signing anything.
