Official communication layer between your Trezor wallet and browser apps.
Modern browsers are built with strict security protocols that limit direct USB access. This is great for safety—but it creates a challenge for crypto users who rely on hardware wallets. Enter Trezor Bridge®, the official helper software from SatoshiLabs that solves this problem by creating a secure, local communication channel between your browser and your Trezor device. Whether you're using Trezor Suite Web or other compatible wallets, Trezor Bridge® ensures smooth, encrypted interaction without compromising your private keys.
Trezor Bridge® is a lightweight, local application that acts as a secure transport layer between your Trezor hardware wallet and browser-based apps. It enables your device to communicate with web interfaces like Trezor Suite Web, while keeping all sensitive operations—like signing transactions—confined to the hardware wallet itself. This design minimizes the attack surface and ensures that your private keys never touch your browser environment.
Trezor Bridge® is developed by SatoshiLabs, the creators of the world’s first hardware wallet. With over a decade of innovation in crypto security, SatoshiLabs maintains a strong reputation for open-source development, regular updates, and privacy-first design. The Bridge ensures that your private keys never leave your device, guaranteeing peace of mind during every transaction.
