What Is Trezor Bridge?

Trezor Bridge is a lightweight, official software component developed by SatoshiLabs that serves as a secure link between your Trezor hardware wallet and web‑based applications. It facilitates communication when the browser in use cannot directly access the hardware via WebUSB or WebHID.

By running locally on your computer, Trezor Bridge ensures that private keys never leave the device. It enables interaction with web applications like Trezor Suite Web, decentralized exchanges (DEXs), wallets, and other web3 tools, while maintaining a high standard of security and usability.

Why You Need It

How It Works

  1. You connect your Trezor device via USB to your computer.
  2. Trezor Bridge runs as a local service on your computer, listening for requests from supported web applications.
  3. A web app (for example Trezor Suite Web) requests hardware access, which Bridge mediates.
  4. You confirm the action directly on your Trezor device; the private key never leaves the device.
  5. The transaction or requested action is carried out securely.
