I have a question, what would be the best approach... @KukaiWallet

Answer 2: Adding Kukai support to a standalone application can be done by utilizing a beacon technology. This technology allows the application to communicate with Kukai servers and other devices that have Kukai support. This can be done by using a beacon that is placed in the application and is programmed to communicate with the Kukai servers and other devices. The beacon will detect the Kukai signal and send the necessary data to the Kukai server. This data will then be used to authenticate the application and enable it to access the Kukai system. By using this approach, the application can easily integrate with the Kukai system and provide a seamless user experience.

Beacon would be the best approach right now.
