In the world of cryptocurrency, security and usability must go hand in hand. That’s why Trezor, one of the most trusted hardware wallets, uses a special communication tool called Trezor Bridge. It plays a vital role in ensuring that your browser-based wallet experience remains both smooth and secure — without ever compromising your private keys.
If you’re using your Trezor with a web-based interface like wallet.trezor.io or third-party apps such as MetaMask or MyEtherWallet, Trezor Bridge is essential for allowing your browser to talk to your Trezor device.
Trezor Bridge is a small background application that enables communication between your Trezor hardware wallet and your web browser. It’s designed to replace older browser extensions (like the now-deprecated Chrome extension) with a more secure, flexible, and modern solution.
Because browsers are limited in their ability to communicate directly with USB-connected devices (for good security reasons), Trezor Bridge acts as the “middleman.” It ensures secure data exchange between your hardware wallet and any web application that wants to interact with it.
When you plug your Trezor device into your computer, the browser alone cannot communicate with it. That’s where Trezor Bridge comes in. Without it, your browser won’t be able to detect the device or allow you to sign transactions, check balances, or manage your crypto assets.
You’ll need Trezor Bridge if:
However, if you're using Trezor Suite (the desktop application), you don't need Trezor Bridge — Trezor Suite handles device communication internally.
Installing Trezor Bridge is simple and only takes a minute:
After installation, Trezor Bridge runs quietly in the background and connects automatically when needed. There's no need to open it manually — it activates whenever a supported website requests access to your Trezor.
⚠️ Always download Trezor Bridge from the official website to avoid fake versions or malware.
Absolutely. Trezor Bridge is developed and maintained by SatoshiLabs, the creators of Trezor. It is:
Because your private keys never leave the Trezor device, Trezor Bridge only handles encrypted communication. Even if your computer were compromised, no one could extract your private keys or access your funds through the Bridge alone.
