Bridge your browser and apps to your device — safely, privately, reliably.
Trezor Bridge runs on your computer as a small, trusted intermediary. It lets web wallets, portfolio tools, and desktop apps communicate with your connected Trezor device without exposing private keys or sensitive data to the network. Think of it as a secure local channel: lightweight, permissioned, and designed to minimize risk while keeping the experience seamless.
Privacy-first
Bridge operates locally on your machine — no remote servers or cloud relays. Requests stay on your host until you approve them on-device.
Verified Signing
All signing requests are shown on the physical Trezor screen. Only after you confirm will a signature be produced, keeping private keys offline.
Cross-platform
Available installers for Windows, macOS, and Linux with automatic updates and simple installation steps.
Developer-friendly
Well-documented local APIs and example integrations make it straightforward for apps to support Trezor devices securely.
How Trezor Bridge works
- Your browser or desktop app sends a request to the Bridge service running on your computer.
- Bridge verifies the origin and forwards the encrypted request to the connected Trezor device via USB or supported transport.
- The Trezor device displays transaction details and requests manual confirmation from you.
- Once you approve, the device signs the transaction locally and Bridge relays the signed data back to the originating app for broadcast.
Bridge is a relay only — it never stores or transmits your private keys. All key material remains inside the Trezor at all times.
