Connect 10.0.0 Migration

Version 10.0.0 introduces significant changes to the integration methods and supported cryptocurrencies.

​
Breaking Changes

Connect 10.0.0 removes legacy iframe and popup integration methods. You must migrate to the new Suite-based integration.
The following integration methods have been removed:
  • connect-iframe: Legacy iframe integration
  • connect-popup: Legacy popup integration
These are replaced with the new Suite-based integration that provides better security and user experience.
Version 10.0.0 removes support for:
  • EOS: All EOS-related methods and functionality
  • NEM: All NEM-related methods and functionality
If your application depends on these cryptocurrencies, you must continue using Connect 9.x or migrate to supported alternatives.
Version 10.0.0 introduces:
  • Tron Support: New tronGetAddress and tronSignTransaction methods
  • Suite-based Integration: Improved security and user experience
  • Enhanced THP Support: Better Trezor Host Protocol implementation

  },
  popup: true
});

Test Integration

Thoroughly test your integration with the new version:
  • Test all supported cryptocurrencies
  • Verify error handling
  • Check user experience flow

​
New Tron Support

If you want to add Tron support to your application: 
// Get Tron address
const result = await TrezorConnect.tronGetAddress({
  path: "m/44'/195'/0'/0/0",
  showOnTrezor: true
});

if (result.success) {
  console.log('Tron address:', result.payload.address);
}

// Sign Tron transaction
const signResult = await TrezorConnect.tronSignTransaction({
  path: "m/44'/195'/0'/0/0",
  transaction: {
    // Transaction data
  }
});
