WhatsApp usernames needs to be an nft, like telegram/fragment.com

WhatsApp has 2.7 billion users. Telegram has a fraction of that but has launched fragment.com on 2022 for users to mint their username on the ton blockchain as an Nft. Set an auction for it, many people were able to make so much money with telegram making approximately $4 billion immediately. Recently a username: PIKACHU. Sold for $80,000 after being bid by different people. I think WhatsApp can launch something like that. Maybe name it metaname.com, create a token on Eth and then launch it on Eth blockchain or create a new blockchain. Will be mind blowing, people will love it
