Trezor Bridge is a secure software utility that enables encrypted communication between your Trezor hardware wallet and browser-based applications. Acting as a local proxy, it ensures your private keys never leave your device while performing crypto transactions, signing messages, or accessing decentralized apps.
In today’s digital landscape, secure device communication is critical. Trezor Bridge eliminates browser extension vulnerabilities and provides a direct, encrypted channel for USB HID and CDC protocols. It supports Trezor Suite and third-party wallets, ensuring compatibility across platforms.
Trezor Bridge runs as a background service on your computer. It listens for requests from browser apps and translates them into secure USB commands for your Trezor hardware wallet. This ensures that sensitive operations like address derivation and transaction signing are handled locally, without exposing your keys to the internet.
The security architecture of Trezor Bridge is built on the principle of isolation. It avoids browser-level APIs that may be inconsistent or insecure, and instead uses a controlled local endpoint. This design prevents unauthorized access and protects against phishing, malware, and man-in-the-middle attacks.
Developers can integrate Trezor Bridge into web wallets and desktop apps using its exposed API. This allows for secure cryptographic operations without direct access to private keys. The bridge supports WebUSB fallback and is ideal for environments lacking native USB support.
While Trezor Suite offers a modern interface, Trezor Bridge remains essential for legacy apps and browser compatibility. Users can run both simultaneously, ensuring smooth migration and continued access to secure device communication.
Trezor Bridge securely connects your Trezor hardware wallet to browser apps using encrypted USB communication.
Yes, it runs locally and uses secure protocols to prevent exposure of private keys or sensitive data.
