Thanks for sharing, we didn't know ledn before, but from a quick look at it, it seems to be a custodial solution from which you can get a dollar loan within 24 hours.

The idea of lendasat is to directly pay your lightning invoices and thus give you an instant collateralized loan. So the loan would be issued within seconds not hours.

Furthermore, lendasat is designed to be non-custodial, meaning that you have a unilateral out if there is a dispute. We achieve that by making use of DLCs and a price oracle. see also https://www.lendasat.com

This is a Bitcoin-only product, so no fiat or stable coin involved.
