No problem! I looked into this deeply when setting up my family with LndHUB on my Lightning node.

I had hoped to simply credit their balances directly, but there was no obvious way to do that. Instead I had to have them “fund” their Lightning wallets through the Blue Wallet mechanism that gives them an on-chain address to send to.

It’s kind of a bootstrapping problem. Suppose you already have a working lightning node. Now you want to make a Blue Wallet Lightning wallet. There’s no way to transfer funds from your Lightning wallet to the LndHUB account. Paying an invoice fails with an obscure error. I’d have to dig up my notes for more details, it’s been a while. 😅
