🚀 What Is Trezor Bridge?

Trezor Bridge is a lightweight background service developed by SatoshiLabs that acts as the secure communication layer between your Trezor hardware wallet (like the Model T or Model One) and your web browser or the Trezor Suite application. Think of it as a silent translator: it sits in the background, listening for when you plug in your device, and sets up an encrypted connection that allows transactions, firmware updates, account signing, and blockchain interactions to flow safely. This method replaces the older Trezor Chrome extension and ensures compatibility across mainstream browsers like Chrome, Firefox, Brave, and Edge without requiring plugins GitHub+9bridgetrezor.m-pages.com+9Google Sites+9.

📌 Why You NEED Trezor Bridge

Security without compromise
 Bridge encrypts all communications between your hardware wallet and software interfaces.
