Is my Bravewallet fished?

Hello, I’m new here and have a question. I use my wallet for Opensea (NFT). Whatever I want to purchase, I see the same public key (code number) were I have to send my money to. It’s not my own key number and I find it very suspicious. I have my wallet since yesterday and I don’t dare to buy anything. Any suggestions?
