What's FDUSD on Binance?

Hey there, I'm curious about something I've noticed on Binance. What exactly is FDUSD? I've seen it listed among the various trading pairs, but I'm not quite sure what it represents or how it functions within the crypto ecosystem. Is it a stablecoin? A derivative product? Or something else entirely? I'd really appreciate it if you could break it down for me in a way that's easy to understand. Thanks in advance for your help!
