Trezor Bridge® | Secure Communication Layer Between Trezor Wallet and Your Browser

Explore Trezor Bridge®, the essential interface that connects your Trezor hardware wallet to your browser. Learn its features, benefits, setup guide, and why it’s crucial for secure crypto transactions.

What is Trezor Bridge?

Trezor Bridge is a lightweight communication interface that enables your browser to interact with your Trezor hardware wallet. Developed by SatoshiLabs, this bridge acts as a crucial link, allowing secure, seamless access between your device and Trezor Suite or compatible web applications without requiring third-party browser extensions.

It replaces the older Chrome-based Trezor Chrome Extension and supports all modern browsers such as Chrome, Firefox, Edge, and Brave. Whether you're storing Bitcoin, Ethereum, or hundreds of altcoins, Trezor Bridge ensures smooth and safe interaction between your hardware wallet and your desktop environment.

Why Do You Need Trezor Bridge?

Without Trezor Bridge installed, your browser cannot communicate with your Trezor hardware wallet. This software layer is essential for:

• Secure Transaction Signing
• Viewing and Managing Assets via Trezor Suite
• Firmware Updates and Device Backup
• Accessing dApps and DeFi platforms securely

In essence, Trezor Bridge is what allows your hardware wallet to function fully as part of your desktop crypto toolkit.

Trezor Bridge vs Browser Extensions

Previously, Trezor offered a browser extension for Chrome users, but it was deprecated in favor of Bridge due to security concerns. Extensions can be vulnerable to malware, phishing, or tracking—whereas Bridge is locally installed, non-browser dependent, and open-source, making it a safer option.
