Why do I have FDUSD?

Could you please explain to me why I have FDUSD? I'm a bit confused as to how it got into my possession. I'm not entirely familiar with the intricacies of cryptocurrencies, so it would be helpful if you could break it down for me. I'd like to understand where it came from, what it represents, and if there's any specific reason why I have it. Could it be related to some recent transactions I made? Or is it a part of some promotion or reward system? I'm just trying to get a clearer picture of my financial situation, and FDUSD seems to be a crucial piece of that puzzle. Thank you for your assistance.
