The wallet can run on top of any lightning-network funding source, currently there is support for LND, CLightning, Lntxbot, LNpay, OpenNode, with more being added regularily.
See [lnbits.org](https://lnbits.org) for more detailed documentation.
LNbits is inspired by all the great work of [opennode.com](https://www.opennode.com/), and in particular [lnpay.co](https://lnpay.co/). Both work as excellent funding sources for LNbits!
LNURL has a fallback scheme, so if scanned by a regular QR code reader it can default to a URL. LNbits exploits this to generate an instant wallet using the [LNURL-withdraw](https://github.com/btcontract/lnurl-rfc/blob/master/lnurl-withdraw.md).
Example use would be an ATM, which utilises LNURL, if the user scans the QR with a regular QR code scanner app, they will stilll be able to access the funds.
