What is NomiSwap?

Could you please explain to me what NomiSwap is? I've heard it mentioned in the context of cryptocurrency and decentralized finance, but I'm not entirely sure what it entails. Is it a type of exchange, a protocol, or something else entirely? How does it work, and what sets it apart from other similar platforms in the market? I'm particularly interested in understanding its use cases, benefits for users, and any potential risks or limitations associated with using NomiSwap.
