Trezor Bridge is the purpose-built communication layer that creates a secure connection between your computer and your Trezor hardware wallet. When you download Trezor Bridge and install the bridge service, your system gains a trusted channel for device detection, firmware updates, transaction signing, and safe wallet interactions. Trezor Bridge keeps private keys on your device while enabling desktop interfaces to interact with your Trezor without exposing sensitive material.
Why Trezor Bridge matters:
- Secure connection: Trezor Bridge establishes encrypted, local-only communication that ensures requests to sign or update are validated by the device itself.
- Reliable detection: Trezor Bridge simplifies device detection across Windows, macOS, and Linux so users can focus on secure operations, not driver hassles.
- Firmware & updates: Bridge safely coordinates firmware flashing and device verification flows with clear user prompts.
- Compatibility: Works with desktop wallets, Suite-style apps, and web interfaces that rely on a local bridge for improved UX.
