🔧 Trezor Bridge 2025 — Secure, Seamless Communication for Your Trezor Wallet

When using a Trezor hardware wallet with web-based platforms—like Trezor Suite, dApps, DeFi tools, or third-party wallets—Trezor Bridge acts as the critical link between your device and your browser. Unlike browser plugins that pose security risks, Bridge is a lightweight, secure background client that ensures your private keys remain offline, your data is encrypted, and your experience stays smooth. In short: Trezor Bridge is the secure handshake that brings the physical security of Trezor to the web.


What is Trezor Bridge?

Trezor Bridge is a cross-platform background service (Windows, macOS, Linux) that enables seamless, secure interaction between your Trezor hardware wallet and web-based interfaces—without relying on browser extensions. It replaces legacy tools like Trezor Connect, offering stronger encryption, automatic updates, and wider browser compatibility bridge-docs-trzor-en.gitbook.io+12bridge-docs---tzrzc.gitbook.io+12learn-bridge----trzor.gitbook.io+12Trezor Bridge+8bridge-docs---trezr.gitbook.io+8bridge-docs------trezor.gitbook.io+8.

Once installed, it runs quietly—launching whenever you connect your Trezor so that websites like Trezor Suite or other trusted crypto apps can communicate with your device securely.
