NFT transactions showing up in my backend

Hello. Just wondering how NFT transaction data is appearing in my backend ? Am I losing my mind and did I must have done an NFT project and didn’t know about it ? I am only transferring erc20 tokens with my project. I need a sanity check. Am I connected to other users data as well ?

you say that you have to NFT transactions in your server db and you don’t know from where?
you could look in that specific transactions data in that case (maybe it is a problem on our side)
