Yes, some developers have successfully deployed custom child tokens using FxPortal custom token contracts on Polygon. FxPortal allows assets to move between Ethereum and Polygon while supporting custom implementations.

To deploy a custom child token, you typically:

  1. Deploy the Custom Token on Ethereum – Implement the IFxERC20 interface.
  2. Register the Token with FxPortal – Use the FxRoot contract for mapping.
  3. Deploy the Child Token on Polygon – Implement IFxERC20 on Polygon.
  4. Test and Verify Transfers – Ensure proper state sync and message passing.
