When it comes to securing cryptocurrency, Trezor® hardware wallets are trusted worldwide. But to ensure seamless communication between your Trezor device and your web browser, you need a secure connection layer — that’s where Trezor Bridge® comes in.
Trezor Bridge is the official communication software developed by SatoshiLabs to enable secure interaction between your Trezor hardware wallet and supported browsers. If you’re setting up your wallet through the official website https://trezor.io/start , installing Trezor Bridge is an essential step.
In this comprehensive guide, you’ll learn what Trezor Bridge is, why it’s important, how to install it, and how it enhances your crypto security.
🔵 What Is Trezor Bridge®?
Trezor Bridge® is a background application that allows your computer’s web browser to communicate securely with your Trezor hardware wallet.
In simple terms, it acts as a secure translator between:
Your Trezor device (Model One or Model T)
Your computer operating system
Your browser
Trezor Suite Web
Without Trezor Bridge, your browser would not recognize or properly communicate with your hardware wallet.
You can download the official version directly from: 👉 https://trezor.io/trezor-bridge
