Trezor Bridge — Secure Wallet Communication Layer App

A secure, fast bridge between your Trezor device and the web

Trezor Bridge is the communication layer that connects hardware wallets to desktop and web applications. Built for privacy-first users, it provides encrypted, local-only transport, robust device discovery, and a developer-friendly API so web wallets and apps can talk to a Trezor device without compromising security.

Private & Local

Runs locally on your machine and never proxies keys or secrets through third-party servers.

Cross-Platform

Native support for Windows, macOS and major Linux distributions with seamless updates.

Reliable Device Detection

Works across browsers and USB layers — automatic device discovery and connection resilience.

Developer API

HTTP JSON API and WebSocket connectors make integration with web wallets simple and secure.

Why it matters

Connecting a hardware wallet to a web app without a dedicated bridge risks unstable connections or exposing endpoints. Trezor Bridge ensures the communication layer between your browser, desktop apps, and Trezor device is encrypted, authenticated and auditable. This improves wallet security and speeds up app approval by reducing integration complexity.

Secure

Quick Start

Install, open your Trezor, and authorize web apps.

# macOS (example) curl -sSfL https://bridge.trezor.io/install.sh | sh # Open your browser & connect device

Integration Highlights

Local JSON-RPC over HTTP
Optional WebSocket streaming for events
Secure origin checks for web apps

Frequently Asked Questions

1. What is Trezor Bridge and why do I need it?

Trezor Bridge is a local communication layer app that enables secure communication between your Trezor hardware wallet and web or desktop applications. It manages USB / HID connections, authenticates origins, and transports messages without exposing private keys. You need it for reliable, secure connectivity across browsers and apps.

2. Is my data sent to remote servers?

No. Trezor Bridge runs locally and forwards commands only between your browser/app and your device. No private wallet keys or seeds are transmitted off your machine.

3. How do developers integrate with the bridge?

Developers use the documented HTTP JSON API or WebSocket endpoints exposed by the bridge. Official client libraries and examples speed up integration and help with origin verification and permission flows.

4. Which platforms are supported?

Trezor Bridge supports modern Windows (10+), macOS (10.14+), and popular Linux distributions. Signed installers provide a secure installation path and automatic updates.

5. Troubleshooting tips if my device isn't detected?

Ensure the bridge is running, try a different USB port or cable, disable other wallet apps that may claim the device, and check OS permissions. Reinstalling the Bridge and restarting the browser often resolves detection issues.
