Has anyone deployed custom child token using fxportal custom token contracts?

I am trying to deploy custom FxChildTunnelContract using fx–portal’s examples. I am not sure about the steps. Can someone help?

Let’s see. Can you link to the examples please?

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.
