What is SWIP swap?

Can you please explain to me what exactly is a SWIP swap in the world of cryptocurrency and finance? I've heard about it but I'm not entirely clear on how it works or its significance in the market. Is it a form of decentralized exchange, or does it have a different function altogether? I'm curious to learn more about the mechanics behind SWIP swaps and how they fit into the broader ecosystem of digital assets and financial transactions.
