Tŕezor™ Bŕridge: | Securing℗ Your Digital Assets©

In today’s rapidly evolving digital landscape, protecting your cryptocurrency assets is not a choice — it’s a necessity. Trezor™ Bridge plays a crucial role in this process by serving as the communication layer between your Trezor hardware wallet and your computer. Whether you're sending Bitcoin or managing Ethereum tokens, Bridge ensures a secure, private link between your browser and device.

🌉 What is Trezor Bridge?

Trezor Bridge is a background service that enables communication between your Trezor hardware wallet and supported web interfaces, such as Trezor Suite Web and third-party apps like MetaMask (when configured correctly).

It replaces the now-deprecated Chrome extension, offering a more secure, cross-browser, cross-platform communication channel.

🔧 Why You Need Trezor Bridge

Without Trezor Bridge, your browser cannot directly access or interact with your Trezor device — making Bridge a vital component of the ecosystem.

🧠 How Trezor Bridge Works

Once installed, Bridge runs as a local service on your machine, listening on port 21325. When you visit a supported web interface (e.g. Trezor Suite Web), your browser communicates with this local service, which in turn securely relays messages to your Trezor hardware wallet.

🔐 Security Features

This architecture ensures that even if your computer is compromised, unauthorized access to your assets is extremely difficult without physical access to your device and PIN.
