Securely Connect Your Hardware Wallet with a Seamless App Experience
Trezor Bridge is a communication interface between your Trezor hardware wallet and web browsers or native apps. It allows your computer to recognize and interact with your Trezor device, enabling secure transactions, wallet access, and more.
Developed by SatoshiLabs, Trezor Bridge has replaced older browser-based extensions to deliver a safer and more stable experience across platforms.
Without Trezor Bridge, your browser or app can't communicate securely with the Trezor hardware wallet.
It is the backbone of your device's connection to the software ecosystem.
Early versions of Trezor used browser extensions (Chrome, Firefox) to establish communication. However, due to increasing browser security restrictions, these became less reliable.
Trezor Bridge emerged as a unified, OS-level service that works outside the browser — delivering better performance, privacy, and stability.
