Trezor Bridge — Complete Guide

Trezor Bridge is a small software application that acts as a communication layer between your Trezor hardware wallet and your computer’s browser or Trezor Suite. Without it, your computer may not be able to detect your device properly. Trezor Bridge is required to securely manage your cryptocurrencies using Trezor Suite or web-based wallets like MyEtherWallet.

Here’s a complete guide on what Trezor Bridge is, how to install it, and best practices for secure usage.

What Is Trezor Bridge?

Trezor Bridge is essentially a device driver for your Trezor hardware wallet. It ensures that your computer can communicate with the device over USB securely, without exposing your private keys.

Key functions of Trezor Bridge include:

  • Enabling web browsers to detect your Trezor device.

Without Trezor Bridge, Trezor devices cannot connect to web wallets or even Trezor Suite on some operating systems.
