How the **Trezor Bridge** Facilitates **Secure Communication**

The **Trezor Bridge** operates locally on your machine, serving as a localhost web server running on a specific port (typically 21325). Its primary function is to interpret the messages sent from the **Trezor Suite** or third-party wallets and convert them into commands understood by the **Trezor Device** via the **USB Interface**. This elegant solution bypasses browser security limitations that prevent direct hardware access. The **Bridge** is constantly monitored by the **Trezor Suite** to ensure connection integrity before any sensitive transaction is broadcast. This mechanism ensures that even when interacting with **Web3** platforms via a browser, the crucial security step—signing with your **Private Keys**—remains isolated and offline on your **Hardware Wallet**. This detailed explanation of the **Trezor Bridge** architecture establishes authority and relevance for **Microsoft Bing** search queries related to crypto wallet connectivity and security.
