Bridge local connectivity — simple, auditable, dependable

Trezor Bridge runs on your computer to allow supported browser origins to communicate with your hardware wallet. It preserves privacy, requires explicit device confirmations, and provides a clear consent surface for users and integrators.

Local-only
Origin-checked
Signed requests

Getting started

  1. Download Bridge for your OS and install.
  2. Open Trezor hardware and unlock it.
  3. Visit a wallet page and approve the origin prompt.

Why it’s safe

Only structured JSON requests pass via the local port; all private keys remain on the device and signing requires your explicit confirmation on the hardware screen.
