Now that Cash App uses the lightning network, does that make it more likely for them to offer other services built on bitcoin's layer 2?

I found an article on cointelegraph that seemed to imply that stablecoins on the liquid sidechain could be sent over the lightning network. That didn't sound right to me.

I assume that it's just liquid's own parallel implementation of the payment-channel tech. Like the lumino network on RSK. But then that got me thinking about how different lightning networks could use atomic swaps to interact with each other directly. I've read that atomic swaps only work if the two blockchains support the same hashing algorithm. So I think a merge mined network like RSK should have no trouble hooking up the lumino network directly to the lightning network.

I assume liquid is actually doing something like that right?.

Then I thought about tokens issued on top of bitcoin's lightning network. Like RGB. How are stablecoins made with RGB transferred? Do they just use the lightning network itself, or do they have their own payment channels?

My questions aren't necessarily specific to a single layer 2 technology so I thought it would be relevant for a general bitcoin sub.

Here's the article that got me thinking: https://cointelegraph.com/news/bitcoin-lightning-network-works-on-liquid-sidechain-blockstream-confirms

Cash App recently started using the lightning network. If companies like Cash App start using stablecoins for USD transfers, is it likely that they prefer ones running on layer 2 of the bitcoin network for ease of lightning network interoperability?

Seems to me this line of questioning is super relevant to the market for bitcoin specifically.
