What is Trezor Bridge?

Trezor Bridge is a communication tool developed by SatoshiLabs (the creators of Trezor hardware wallets). It acts as a secure channel between your Trezor hardware wallet and your computer’s web browser. Essentially, it lets your browser (like Chrome, Firefox, or Edge) recognize your Trezor device so you can safely manage your crypto assets through the Trezor Suite web interface or other compatible wallets.

Older versions used a Chrome extension called “Trezor Chrome Extension” or “Trezor Connect,” but that method is outdated. Trezor Bridge is more reliable, secure, and works across all major browsers. Without Trezor Bridge, your device might not connect properly when you try to access your wallet online.

Why Do You Need Trezor Bridge?

When you plug in your Trezor device, your browser alone cannot communicate directly with the device’s firmware. Trezor Bridge fills this gap by handling USB communication securely. It’s lightweight, runs in the background, and doesn’t store any private keys — the keys always stay offline on your hardware wallet. Bridge only transmits the necessary commands to sign transactions or display balances.
