You can pay a boltz swap lightning invoice from Cash app. So you can swap straight to liquid already. Don't really need cash app support here. What's RSK? UK would be good to.

Yeah but there wouldn’t be a fee if it was directly supported, cut out the middle man. Let’s just integrate scaling solutions everywhere we can and take the pressure off the mainchain. RSK is another sidechain, Rootstock.
Boltz is open source. You could run it yourself and remove the fee but yes direct support would be nice. I just mean for priority sake, POS integration with existing square systems is priority #1.
