Trezor Bridge is a secure communication software developed by SatoshiLabs to connect your Trezor hardware wallet with your computer and the Trezor Suite. It establishes a private, encrypted link between your wallet and desktop, ensuring every crypto action is verified on your device and never exposed online. With Trezor Bridge, your digital wealth stays safe and fully under your control.
What Is Trezor Bridge?
The Trezor Bridge is a background software that enables communication between your Trezor wallet and supported browsers or the Trezor Suite app. Instead of relying on outdated browser extensions, it provides a secure, system-level connection, ensuring reliable and protected crypto management. It’s the invisible layer of trust every Trezor user depends on.
Why You Need Trezor Bridge
Without the Trezor Bridge, your computer won’t be able to detect your hardware wallet properly. The Bridge ensures encrypted, authenticated communication between your device and apps, letting you view balances, sign transactions, or update firmware securely. Every confirmation happens on the Trezor’s screen — keeping phishing and malware threats away.
