Bridge your Trezor to the web — Simple. Secure. Local.

Trezor Bridge runs locally to allow web apps and desktop clients to talk to your hardware wallet without exposing keys or creating cloud dependencies.

Why Bridge?

Isolates device communications on your machine, reduces attack surface, supports multiple platforms and browsers.

Supported OS

Windows, macOS, Linux — incl. ARM builds for M-series and Raspberry Pi.

Privacy

No telemetry. No cloud relay. Bridge listens on localhost only and requires user permission on first connect.

Auto-updates

Optional auto-updates keep you secure; enterprise builds available with centralized management.

Quick install

Download

Grab the installer for your OS above.

Run installer

Approve the local service — Bridge runs in background.

Connect device

Open your wallet app and allow the connection when prompted.

Bridge — Local Service

Developers

Bridge exposes a simple HTTP API on localhost for browser integrations. Example (fetch):

fetch('http://127.0.0.1:21325/api/info')
  .then(r=>r.json())
  .then(console.log)

Always prompt users and verify device details before signing operations.

Security notes

Bridge runs on localhost only and uses OS-level signing for updates.
Check binary signatures and download only from official sources.
For automated environments, use signed enterprise installers.
