LND Hub

LND Hub is a wrapper around LND that turns one node into many accounts. It was built by the BlueWallet team so that a mobile wallet could offer instant Lightning payments backed by a node, without every user needing to run one.

On your own MyNode the interesting use is the reverse of the hosted case: instead of trusting somebody else's hub, you run the hub and point your phone at it. BlueWallet connects to your LND Hub instance, and your Lightning balance on mobile is backed by channels you own, on hardware in your home.

Because accounts are issued separately, this extends to people you actually know. You can hand an account to family or a friend so they can send and receive Lightning payments without setting up a node, managing channels, or worrying about liquidity — while the funds stay in a node you control.

It is worth being clear about the trust model. Accounts on a hub are custodial with respect to the hub operator: balances are tracked in the hub's database rather than being separate channels per user. That is fine when you are the operator and the users are you and your household, and it is the whole reason to prefer your own instance over a public one.
