The wax wallet is only needed for pre registration to enter the contest.
You can attend the event without having a wax wallet. All you need is an email address to login to the event on the day.
You want to make a profile before the event you can make one here at the previous NFTopia https://framevr.io/nftopia4
I hope that helps
Please note that there will be a lot of Wax giveaways on the day so having a wax wallet will be beneficial at the event
