How does biswap work?

I'm curious to understand the workings of Biswap. Could you please explain in simple terms how it functions? How does it facilitate trades and swaps between different cryptocurrencies? Is there a specific mechanism or protocol that Biswap uses to ensure efficient and secure transactions? I'm particularly interested in knowing about the user experience, as well as any unique features that Biswap offers compared to other decentralized exchange platforms.
