Why Trezor Bridge?

Trezor Bridge solves a key problem: secure, reliable communication between web applications or desktop wallets and your Trezor hardware device. Unlike generic USB drivers, Trezor Bridge understands the secure protocol used by Trezor devices, ensuring that signing requests and recovery operations are handled with the correct permissions and explicit user confirmation on the device itself.

Trezor Bridge acts as a gateway that reduces friction while preserving security: it isolates device access, handles origin checks for browser connections, and provides a stable local endpoint that wallet apps can use to discover and talk to your device. When you use Trezor Bridge, you get fast device detection, stable connections while syncing, and a predictable workflow for signing transactions.

Developer Docs & Integration

Developers integrating Trezor devices should use the Trezor Connect API in combination with Trezor Bridge for desktop and browser flows. Trezor Bridge exposes a local endpoint that guarantees origin checks and secure message routing. Use Trezor Connect to request accounts, sign transactions, and perform device-level operations while instructing users to confirm actions on the hardware.

Secure Signing

All signing operations require explicit confirmation on the device. Trezor Bridge forwards signing requests and prevents silent signing by design.

Origin & Permission Checks

Trezor Bridge enforces origin validation for browser apps. Only trusted origins allowed by the user can communicate with the device via the bridge.

Stable Discovery

Bridge maintains a consistent local discovery API so wallet apps can detect connected devices and handle hot-plugging reliably.

Cross-Platform Support

Trezor Bridge supports Windows, macOS, and Linux with the same secure protocol and developer integration patterns.

Security Best Practices

Trezor Bridge is designed with security-first principles, but users and developers should follow best practices: always download Trezor Bridge from the official site, confirm TLS/HTTPS, keep software up to date, verify transaction details on your Trezor device, and never share your recovery seed. For enterprise deployments, restrict local machine access, and use device policies where possible.
