What is leet swap?

Excuse me, could you please explain what Leet Swap is? I've heard it mentioned in the cryptocurrency circles but I'm not entirely sure of its purpose or functionality. Is it a decentralized exchange, a token swap service, 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 unique selling points and the benefits it offers to users. Could you elaborate on that, please?
