Optimism drop into my Coinbase Wallet app Possible scam?

Hello,

I had dabbled in crypto a while ago and used the Coinbase Wallet app along with the Coinbase website and would sell ETH to take out the cash. I stopped using it over a year ago and recently logged in to see that OP has been dropped into my wallet.

Were there any known scams out there like this? I searched in different reddit subs for any posts and did a quick google search but nothing really came up. Google did say there had been a wave of scams but not sure if it was the same thing.

If I try to send the OP to my Coinbase it says I don't have enough ETH but does not show any gas fees.

Not really sure how to proceed with it and if I can even cash out this token.

Any help/insight would be much appreciated!

Thanks.

Edit/Add: I checked etherscan and it shows the transfer so it must be legit, from their recent airdrop.
