Trezor Bridge – Secure Communication Between Your Trezor Wallet and Browser

Trezor Bridge is a secure tool that connects your Trezor Wallet to supported browsers and platforms like Trezor Suite and Trezor Connect. Learn how to install, use, and troubleshoot Trezor Bridge.

What is Trezor Bridge?

Trezor Bridge is a communication interface developed by SatoshiLabs that allows your Trezor hardware wallet to interact securely with your computer’s browser. Acting as a link between your Trezor device and supported applications such as Trezor Suite and Trezor Connect, it ensures smooth operation and safe crypto management directly from your desktop.

Unlike browser extensions, Trezor Bridge runs as a background service, providing better performance, improved reliability, and enhanced compatibility across browsers.

Trezor Bridge is essential for:

• Establishing secure communication between your computer and Trezor device
• Enabling your browser to detect and authorize Trezor transactions

• Avoiding browser-based connection limitations, especially in Google Chrome and Mozilla Firefox
