Overview
Trezor Bridge is the official connection software that provides a secure and reliable interface between Trezor hardware wallets and desktop or web applications. Bridge ensures that all sensitive operations, including transaction signing, occur directly on the device while only transmitting encrypted responses to the host application. This keeps private keys isolated and safe from malware or phishing attacks. https://trezor.io/bridge
KEY STUFFING: Trezor Bridge — Secure Wallet Connection
Bridge manages USB/WebUSB communication, abstracts OS-specific behaviors, and ensures a consistent experience across Windows, macOS, and Linux. Whether you are sending Bitcoin, Ethereum, or managing other supported tokens, Bridge provides a transparent and auditable channel for your device interactions. Developers can also review the open-source code to verify security and integrate Bridge into their apps with confidence. https://trezor.io/bridge

With Bridge installed, Trezor Suite or any compatible wallet can automatically detect your device, list accounts, and display balances. Bridge facilitates secure signing requests and ensures that all actions are confirmed on the hardware wallet before being returned to the application. This workflow protects against remote attacks and ensures that only user-approved operations are executed. https://trezor.io/bridge

Installation & Setup
Installing Trezor Bridge is straightforward. Download the official installer for your operating system from the Trezor website, run the installer, and follow the setup instructions. The installation registers necessary services or udev rules to allow the application to communicate with your hardware wallet safely. Once installed, connect your Trezor device and grant access permissions when prompted. https://trezor.io/bridge

After installation, any Bridge-compatible application will detect your Trezor device automatically. When you initiate a transaction, Bridge securely relays the signing request to the device, which displays all transaction details for user confirmation. Only after confirmation does the device produce the signed data returned to the application. This ensures all sensitive operations remain isolated on the device. https://trezor.io/bridge

Security & Privacy
Trezor Bridge enforces security best practices by ensuring that private keys never leave the hardware wallet. All communications occur locally over loopback interfaces. The hardware wallet displays transaction details for verification, making it impossible for malware on the host system to perform unauthorized actions. Regular updates to Bridge and device firmware help maintain optimal security and reliability. https://trezor.io/bridge

Developer Integration
Developers can leverage Trezor Bridge to integrate secure hardware signing into their applications. Bridge provides APIs and SDKs for JavaScript, Python, and other environments, simplifying development while maintaining strict security. By routing all signing requests through Bridge, developers avoid handling private keys directly, reducing risk and ensuring compliance with security best practices. https://trezor.io/bridge

Troubleshooting & Best Practices
If your Trezor device is not detected, ensure that the USB cable is working and the device is unlocked. On Linux, confirm that udev rules are installed correctly; on macOS and Windows, verify the service is running. Reinstalling the latest official Bridge release can resolve most detection issues. Always use the official installer and keep the software and firmware updated. https://trezor.io/bridge
