What Is Trezor Bridge – The Silent Security Hero

Trezor Bridge is a lightweight desktop application created by SatoshiLabs. It acts as a secure “middleware” connecting your Trezor hardware wallet to web-based wallets and browsers like Chrome, Firefox, Edge, and others. By running locally, Bridge eliminates the need for browser extensions and ensures your private keys stay offline while making transactions smooth and secure public-docs-bridge-us.typedream.app+4learn-bridge-trzor.teachable.com+4en-us-brdge-docs-cdnn.teachable.com+4learn-us-brridge.teachable.com+15about_en-bridgetrzr.teachable.com+15web-eng-bridge-docs.teachable.com+15.

Technical Deep Dive – How It Works

Once launched, Bridge listens on a local HTTP endpoint. Browsers send API calls via this endpoint. Bridge translates them into low-level USB commands, relays them to the Trezor, and returns encrypted responses to the browser. Because it's OS‑level, Bridge avoids exposing USB APIs directly to web pages and enhances security and compatibility en-us-trzor-bridge.teachable.com+3faq-bridge-doc-io.github.io+3web-eng-bridge-docs.teachable.com+3about_en-bridgetrzr.teachable.com+1learn-bridge-trzor.teachable.com+1.
