> Do I have access to their sats?

Yes, but there’s no standard UI for accessing individuals’ amounts. It’s in a Redis database that you can query. Presumably one could write code to update this database directly.

> Are they somehow separated?

LndHUB accounts are custodial entries in a Redis database. The sats are commingled in one shared Lightning node’s channels. It’s up to you to maintain enough liquidity to satisfy demand of your users.

> Can I rug them?

Absolutely. It is trivial to do so en masse. Just close all your channels and walk away.

Rugging an individual user is more difficult because there’s no UI for it. But the code is open source so developing a script ought to be possible.

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. 😅

Haha yes!! I remember trying that too! Maybe us plebs could zap the wallets and we fund it that way 😅
