Hey, I am not a dev ans technically illiterate. I dont even know what NWC is. I am vibecoding and accounting system/wallet to manage a family bitcoin. Teach children about money and person finance while managing real life balances, allowances and savings. The on chain balance is view only via the xpub and all distributions are just an abstraction, an internal accounting system. When any transaction is needed all I do is create a PSBT and sign it with my hardware wallet on sparrow. But I want my kids to be able to spend their spending balances in lightning by using my node (or lihhtning wallet) whitin apps parental controls. What I am failling to do is to use my app (a replit app) to access my node or wallet and pay an invoice.
