Trezor Bridge: Seamless Integration for Your Hardware Wallet
Trezor Bridge is a software utility developed by SatoshiLabs to enable secure communication between your Trezor hardware wallet and your web browser. If you own a Trezor device and use services such as Trezor Suite or third-party applications like MyEtherWallet, Trezor Bridge is the invisible hero that connects your device to the web securely and reliably.
Why Trezor Bridge?
Unlike browser extensions, which can be prone to compatibility issues or security vulnerabilities, Trezor Bridge provides a more stable and secure communication channel. Before its introduction, users relied on browser extensions like the Trezor Chrome extension, which had limitations, especially as browser support changed over time. Trezor Bridge solves these problems by operating independently of browser extensions, ensuring seamless connectivity across platforms.
It runs as a background service on your computer, listening for requests from supported web apps and forwarding those securely to your Trezor device. This ensures a more consistent experience and allows you to use your Trezor wallet across different browsers and systems without hassle.
How It Works
Once installed, Trezor Bridge runs a local service on your machine. When you open Trezor Suite or another compatible web application, the browser communicates with Trezor Bridge via localhost (typically http://127.0.0.1:21325). Trezor Bridge then securely relays the communication to your hardware wallet via USB.
This design allows for maximum privacy and security. No sensitive data is transmitted over the internet, and all transactions must be physically confirmed on your Trezor device, protecting you from remote attacks or phishing attempts.
