Trezor Bridge — Simple. Secure. Invisible.

Trezor Bridge is a lightweight background service that securely connects your Trezor hardware wallet to Trezor Suite and trusted web apps. It runs locally, keeps communication isolated, and dramatically simplifies interaction with your device while preserving maximum security.

What Bridge does — in plain language

Bridge sits between your browser/desktop app and the Trezor device. It manages USB/HTTPS communication, negotiates secure sessions, and exposes a tiny API that apps use to talk to your wallet—no keys ever leave your hardware.

Runs locally

Bridge runs on your computer as a trusted local helper. It does not forward data to remote servers—communication happens on your machine.

Secure channel

Bridge establishes a secure, authenticated channel between Suite/web apps and your device. Each transaction is shown and approved on the device screen.

Browser friendly

No complex browser extensions or plugins — Bridge uses safe, modern browser APIs to enable direct device workflows for web apps.

Minimal footprint

Small, well-scoped, and easy to install — Bridge is designed to be unobtrusive while providing essential connectivity.

Quick start — install & connect (under 10 minutes)

Download Bridge from the official site and choose your OS.
Install following the installer prompts. Bridge runs in the background after login.
Open Trezor Suite or supported web app — it will detect Bridge automatically.
Connect your Trezor via USB; confirm device prompts on-screen.
Approve actions on-device — every sensitive action requires physical confirmation.

If you prefer not to use Bridge, advanced users may connect via other supported low-level methods — but Bridge offers the best combination of security and usability for most people.

Security-first design

Bridge is built with the same security-first principles as the Trezor ecosystem. It never handles private keys, does not store seed phrases, and requires device confirmation for signing operations.

Local-only communication

Bridge mediates local connections; no remote server proxies transactions for you.

Verified updates

Installers and Bridge updates are signed and verifiable so you can confirm authenticity before installing.

Minimal privileges

Designed to request only the OS permissions it needs to access USB devices safely.
