What is pswap?

Could you please elaborate on what exactly pswap is? I'm not entirely familiar with the term, and I'm curious to know if it's a specific type of cryptocurrency exchange, a decentralized platform, or perhaps a tool used for swapping tokens within a particular blockchain ecosystem? I'm interested in understanding the key features and benefits of using pswap, as well as any potential risks or limitations that should be considered. Thank you in advance for your clarification.
