Trezor Bridge Official | Seamless Communication Between Wallet & Browser

Trezor Bridge is the lightweight native bridge application that enables secure, reliable communication between your Trezor hardware wallet and web browsers. It acts as the local messenger that confidently delivers commands and responses between your device and wallet-hosting web apps.

Platform: Windows, macOS, Linux Connection: USB Focus: Security & Compatibility

Why Trezor Bridge matters

Trezor Bridge is the recommended connection method for Trezor devices when using browser-based wallet interfaces. Without the bridge, web pages cannot directly talk to hardware devices attached over raw USB in a cross-platform, permissioned manner. Bridge fills that gap by offering a small, vetted native service that exposes a secure API to local browser sessions.

Core features

Secure communication

All messages are proxied between the browser and your Trezor device — user confirmations remain on-device so private keys never leave the hardware.

⚡
Fast & lightweight

Designed to run in the background with minimal footprint; installs quickly and starts automatically when a Trezor device is connected.

🔁
Cross-browser compatibility

Works with popular browsers that support Trezor-friendly integrations, ensuring a consistent experience across Chrome, Edge, and Firefox.

Installation & quick start

Download the latest Trezor Bridge installer for your operating system, run the installer, and follow on-screen instructions. After installation, reconnect your Trezor device and open your preferred wallet web app — the site will detect Bridge and request permission to access the device.

Security best practices

Troubleshooting

If a website cannot find your device, try the following:
