What's the best NFT utility you've ever seen?

[Joseph Lee]

These days, almost every Web3 company tries to create NFTs with some form of utility or the other for the sake of adding more value. While some are only just talk, a few actually live up to expectations and turn out to be crazy useful even in real-world situations and events. I've seen some used as tickets for shows, confirmations for transactions, and most recently as login tools for web3 companies and traditional Web2 apps like Google Meet and Zoom. I think the latter was the most interesting I've seen so far. It was one of the avatars created using Lifeform's DID solution to create hyper-realistic virtual human pictures.

What amazes me the most is how it seamlessly works even on web2 servers, when normally I'd expect its utilities to only be limited to the Web3 space. I still find it exciting, but something tells me there's more amazing stuff out there.

Curious to know which ones you've found most interesting since you started dealing with NFTs.
