What just happened in my account?? Scammed?

I bought something like $35 dollars worth of SpaceX in the Robinhood Wallet App this morning and about an hour ago a contract was interacted and now the coin is gone and the balance is gone. Did I just get scammed by a smart contract? I tried looking into the details and it looks like it was possibly all pulled back a null wallet address. Is my wallet safe? Or is it now at risk? Any information helps, as this is new to me and although Robinhood Wallet has access to more crypto than just the regular Robinhood app it doesn't allow all the coins available to be seen or swapped for. So I thought it was a safer way to buy crypto then the other apps/wallets. Has this happened to anyone else? And the coin is unsearchable but I can still pull it up from my recently viewed coins.
