Deprecation and Removal of Standalone Trezor Bridge

This guide (≈1500 words) explains the deprecation of the standalone Trezor Bridge, migration to Trezor Suite, impacts on users and developers, security considerations, troubleshooting, and best practices — all presented in a colorful, readable format.

Why the Standalone Bridge is Being Deprecated

Trezor Bridge was originally designed to facilitate communication between hardware wallets and browsers. With the evolution of Trezor Suite as a unified desktop and web application, standalone Bridge has become redundant. Consolidating into Suite simplifies updates, improves security, and standardizes the user experience.

Unified App

Centralized control in Trezor Suite

Enhanced Security

Less attack surface, firmware-verified

Cross-Platform

Windows, macOS, Linux support

Transition Path for Users

  • Uninstall the standalone Trezor Bridge from your system.
  • Download and install the latest version of Trezor Suite from the official website.
  • Connect your hardware wallet and verify firmware updates within Suite.
  • Enable cloud sync or local metadata storage as needed.

Developer Considerations

Developers using Trezor Connect must update integration to rely on Trezor Suite instead of standalone Bridge. Key points include:

  • Ensure compatibility with Suite's updated API endpoints.
  • Handle device features and connection prompts through Suite.
  • Test cross-platform behavior to avoid deprecated Bridge dependencies.
// Update TrezorConnect initialization
TrezorConnect.init({
  manifest: {
    email: 'dev@example.com',
    appUrl: 'https://yourapp.com'
  },
  connectSrc: 'https://suite.trezor.io/bridge',
});

Security Enhancements in Trezor Suite

  • Bridge is integrated, reducing system services and attack surfaces.
  • Suite enforces firmware verification before device interaction.
  • Metadata encryption and optional cloud sync ensure privacy and continuity.

Troubleshooting During Migration

  • Device not recognized: ensure Bridge is uninstalled and Suite is running with proper permissions.
  • Connection errors: check USB cables and browser permissions; restart Suite.
  • Legacy scripts: remove dependencies on standalone Bridge URLs and endpoints.

Best Practices

  • Keep Trezor Suite and firmware up to date.
  • Confirm transaction details on device screen only.
  • Store recovery seeds offline and securely.
  • For developers, remove Bridge references and test thoroughly on Suite.

FAQs

  • Q: Can I continue using the old Bridge? A: No, standalone Bridge is deprecated and will no longer receive updates.
  • Q: Is Suite backward compatible with Bridge workflows? A: Yes, Suite integrates all Bridge functionality plus enhanced features.
  • Q: Do I need to change my scripts? A: Yes, update API calls to point to Suite-managed Bridge endpoints.

Conclusion

Migrating from standalone Trezor Bridge to Trezor Suite streamlines the user experience, reduces security risks, and ensures future compatibility with Web3 applications. Following the outlined migration steps and best practices will ensure a smooth transition while maintaining security and functionality.
