Trezor® Bridge: The Secure Connection for Browser-Based Crypto Access

Trezor Bridge is a crucial background service that enables secure communication between your Trezor® hardware wallet and web browsers. Unlike Trezor Suite (the full desktop application), Bridge focuses specifically on facilitating safe interactions with web-based platforms like MetaMask, MyEtherWallet, and other crypto services while maintaining the ironclad security of your hardware wallet.

Why Trezor Bridge Matters

• Private Key Protection: Your sensitive data never leaves the Trezor® device
• Browser Compatibility: Works with Chrome, Firefox, Edge, and Brave
• Mandatory for Web Services: Required for any browser-based Trezor® interactions

How Trezor Bridge Works: The Security Model

1. Local Connection: Runs as a background service on your computer
2. Encrypted Communication: Creates a secure channel between browser and device
3. Physical Verification: All transactions require confirmation on your Trezor®
4. No Key Exposure: Private keys remain isolated on your hardware wallet
