We already have have pancake swap profiles.
My suggestion is simple, drop ".cake" domain name nft to the users with profiles. ofcourse there have to be some other rules for the drop, like having bnb/cake lp token or something.
I believe there can be unlimited amount of amazing usecases for it, other than having it with our wallet and the ability to send/recieve crypto with it, we have cake profiles, nft, pools, farms, IFO and achievements, we can use these to create usecases. leave it to the pancakeswap comunity to suggest the most creative usecases.
I believe that pancakeswap has the best infrastructure for setting up a fair nft domain name drops.
