Security concerns?

[zoultrex]

Hi there @liarco
I wonder what security concerns we should have when deploying this contract on the main net.
It seems very solid and also follow what everyone has been doing, but I wonder if you have any recommendations or if it would be good to go.

I see that the contract has been upgraded to erc721a only a month ago, would you say that everything has been covered since then?

Just to make sure, I don't worry about bugs since I'll be doing a lot of testing, my concern is really about exploits/hacks etc...
