Trezor Bridge

Trezor Bridge is the official software that connects your Trezor hardware wallet to your computer, enabling secure management of cryptocurrencies.

What is Trezor Bridge?

Trezor Bridge is a small, official application developed by SatoshiLabs to facilitate communication between Trezor hardware wallets and computers. When you connect a Trezor device, your browser or desktop app cannot directly communicate with it due to security restrictions. Trezor Bridge acts as a secure intermediary, ensuring that commands, transactions, and sensitive information pass safely from the device to the software managing your crypto assets.

Why Trezor Bridge is Important

The Trezor hardware wallet stores your private keys offline, protecting them from malware and phishing attacks. However, without a bridge, the computer cannot send commands to the device securely. Trezor Bridge provides:

Encrypted communication between your device and computer.
Compatibility with multiple browsers and operating systems.
Support for both Trezor One and Trezor Model T devices.
Secure channel for signing transactions and interacting with dApps.

💡 Tip: Always download Trezor Bridge from the official trezor.io/start page to avoid phishing attacks.

Installation Guide

Visit trezor.io/start and select your operating system.
Download the Trezor Bridge installer compatible with Windows, macOS, or Linux.
Run the installer and follow on-screen instructions.
Once installed, restart your browser or Trezor Suite.
Connect your Trezor device to the computer via USB.

💡 After installation, check your device connection by opening Trezor Suite. If detected, your Trezor Bridge is functioning correctly.
