Trezor Bridge – Secure Communication for Hardware Wallets

What Is Trezor Bridge

Trezor Bridge is a lightweight software developed by SatoshiLabs. It acts as the secure communication layer between your Trezor hardware device (such as Model T or Model One) and web-based wallets or decentralized applications (dApps). Due to browser security restrictions, direct USB access is limited in modern browsers. Bridge restores full interaction while keeping your private keys locked safely in the device.
