Trezor Bridge is an essential software that acts as a communication layer between your Trezor hardware wallet and your web browser. It enables secure interactions with supported cryptocurrency platforms, such as the Trezor Suite or third-party wallets like MetaMask and Electrum, right from your computer. Without Trezor Bridge, your Trezor device won’t be able to properly communicate with browser-based applications or wallet interfaces.
Developed by SatoshiLabs, Trezor Bridge is lightweight, open-source, and runs in the background once installed. It replaces the legacy browser extension that was previously used to connect hardware wallets to websites, ensuring a more reliable and future-proof connection.
Why Trezor Bridge is Important
Trezor wallets are designed with the highest level of security in mind. These hardware wallets are built to store your private keys offline, protecting them from hackers and malware. However, to utilize your Trezor wallet with desktop platforms or browser applications, there needs to be a safe and encrypted communication channel between the wallet and your computer. This is where Trezor Bridge comes in.
It ensures:
How Trezor Bridge Works
Once installed, Trezor Bridge runs silently in the background on your computer. When you plug in your Trezor Model One or Model T, the Bridge recognizes the device and enables browser applications (like Trezor Suite or other dApps) to interact with it. The communication is encrypted and local, meaning no sensitive data is exposed online.
This background service listens for any requests from web apps to communicate with your Trezor device. Once a connection is requested, Trezor Bridge facilitates the process by routing the information securely and enabling device operations such as signing transactions, exporting public keys, and managing wallets.
Installing Trezor Bridge
Installing Trezor Bridge is quick and simple:
After installing, reconnect your Trezor wallet and open Trezor Suite to get started.
✅ Pro Tip: You don’t need to open Trezor Bridge manually. It launches with your system and functions in the background.
Trezor Bridge vs Trezor Suite App
It’s worth noting that Trezor Suite – the official wallet management interface by SatoshiLabs – also comes in a desktop version that doesn’t require Trezor Bridge. However, if you prefer to use the web version of Trezor Suite or third-party wallet services, Trezor Bridge is necessary.
