Connect Your Device with Trezor Bridge

Trezor Bridge is the secure local application that lets your browser and apps communicate safely with your Trezor hardware wallet. With Bridge installed, you can connect, import accounts, and confirm transactions seamlessly.

Trezor device

Reliable connection

Bridge ensures browsers and desktop apps can consistently detect your Trezor across operating systems.

Privacy first

All communication stays local. Your keys never leave your Trezor device.

Developer-friendly

A stable local endpoint makes integration easier for wallets and dApps.

Install and start using Trezor Bridge

Download for Windows, macOS, or Linux. After installation, reconnect your Trezor and access supported apps instantly.

What Bridge Does

+
Trezor Bridge acts as a background service, enabling your computer to talk to your Trezor device securely. It never stores private keys.

Security and Privacy

+
Bridge operates locally. Only apps you grant permission can request access, and all sensitive confirmations happen on the device.

Troubleshooting

+
If your Trezor isn’t detected, check the USB cable, restart your browser, or reinstall Bridge. On Linux, confirm udev rules are set.
Device-first

Keys stay on the Trezor, never exposed to the host computer.

Local-only

Bridge runs only on your machine, minimizing attack surfaces.

Explicit consent

Each transaction requires confirmation on your device screen.

Cross-platform

Supported on Windows, macOS, and major Linux distributions.

Why Trezor Bridge is Essential

Trezor Bridge is more than just a utility—it’s the backbone of how your computer interacts with your hardware wallet. Without it, browsers would struggle to detect your device reliably, and many wallet applications would fail to establish a secure connection. Bridge removes these obstacles, providing a stable local service that ensures smooth operation across platforms.

From a security standpoint, Bridge is deliberately minimalistic. It doesn’t touch your private keys or sensitive wallet data. Instead, its role is to facilitate secure communication. Every critical operation—such as transaction signing or PIN entry—happens exclusively on your Trezor device. This means even if your computer is compromised, attackers cannot extract your keys, because Bridge only transmits requests and responses, never secrets.

Installing Trezor Bridge is quick. Official installers are available for Windows, macOS, and Linux. Once installed, it runs silently in the background, ready whenever you connect your device. After restarting your browser, you’ll notice that supported sites and applications can instantly detect your Trezor, making account management and transaction approval seamless.

For developers, Bridge is equally important. By exposing a stable local endpoint, it makes building integrations with Trezor devices easier and more consistent. This is especially valuable for wallet developers, exchanges, and decentralized apps that need reliable device discovery. Bridge simplifies their job while maintaining strict adherence to Trezor’s security model.

Troubleshooting is straightforward. If your device isn’t recognized, confirm that Bridge is running in the background, check your USB cable, and make sure your browser is up to date. On Linux, installing udev rules may be required. Updating Bridge regularly ensures compatibility and security improvements are always in place.

In conclusion, Trezor Bridge is the invisible connector that ensures your hardware wallet works the way it should. By handling local communication securely and reliably, it protects your assets while giving you a smooth user experience. Whether you’re a first-time user or a developer building crypto apps, installing Bridge is a must for safe and reliable Trezor usage.
