Trezor Bridge — Secure connection for your hardware wallet

Introduction

Trezor Bridge is a secure communication tool that allows your Trezor hardware wallet to interact safely with your computer and browser. Without it, many wallet applications would be unable to detect or communicate with the device. Installing Bridge ensures smooth operation, firmware updates, and reliable crypto transactions. With official support for Windows, macOS, and Linux, it creates a trusted link while keeping your private keys safe on the device itself. This lightweight application is an essential step for every Trezor user, enabling both beginners and advanced holders to manage their digital assets with confidence.

What is Trezor Bridge?

Trezor Bridge is a background service that acts as a secure messenger between your browser or desktop wallet application and the physical Trezor hardware wallet. It is necessary because modern browsers impose strict restrictions on direct USB communication for safety reasons. Bridge overcomes these limitations and provides a trusted communication layer while ensuring your keys never leave the Trezor device.

Why You Need Trezor Bridge

Without Trezor Bridge, your browser may fail to recognize the Trezor device, preventing you from accessing your wallet. With Bridge installed, you can reliably connect your device, approve transactions, and perform updates. It ensures compatibility with Trezor Suite and other wallet interfaces. For any user handling cryptocurrencies on a Trezor, Bridge is a mandatory component.

Supported Systems

• macOS: Supports both Intel and Apple Silicon processors. Installer available in .pkg or .dmg format.

How to Download and Install

1. Visit the official Trezor website and navigate to the Bridge download page.
2. Select the correct installer for your operating system.
