No I'm not involved in resolving anything myself. I shared this as a mere interesting project that needs more visibility and definitely embraces Bitcoin and Nostr ethos. See it as a Wasabi and its coinjoin coordinators, or as you said, Robosats and its trades' operators. These tools need a decentralized infrastructure, and this is one of those projects that allows it to happen.

I that fiat passes through bank accounts in this case too; if you are asking about stablecoins exchange, I've no idea.
