Trezor Bridge | Secure Connection for Trezor Hardware Wallet

Introduction

Trezor Bridge is the essential communication layer that connects your Trezor hardware wallet with your computer's web browser. It ensures a secure and reliable link between your Trezor device and the Trezor Suite or other supported web applications.

What is Trezor Bridge?

Trezor Bridge is a small background service that runs on your computer to facilitate communication between the web browser and your Trezor device. It's required for using Trezor wallets on web interfaces that interact directly with hardware.

Why it Matters

Without Trezor Bridge, your browser may not detect your hardware wallet, preventing secure operations like signing transactions, generating addresses, or updating firmware. Trezor Bridge ensures encrypted and authenticated data transmission between your device and browser.

Main Functions

  • Enable browser access to your Trezor device
  • Securely transmit data to and from your wallet
  • Facilitate firmware updates and wallet initialization
  • Support integration with third-party apps and services
