I would be careful with this and with crypto assets generally, for a few reasons.
One is that this is a very hot thing, and lots of people will be talking about it. Most of those people will not know what they are talking about (me, in 2018 applying to A&O talking about their ether bond), so that's not fatal if you really know your stuff. But!
Another is that for this question you'd want to have a sound understanding of what, for firms, operating in the space would actually look like, and how it would be profitable. To what extent, really, are the big corporate clients in this space? (Apart from like, the big Jan 21 meme stock corps dabbling because it boosts their meme value) Is the market, as it exists, already adequately serviced by firms' fintech offerings?
Third, you need to be able to credibly show the you understand the commercials of the asset class (if you can call it that). I'm not sure that *anyone* actually understands the commercials of NFTs beyond the axiomatic principles of Ape Together Strong and There Will Always Be A Greater Fool.
If you're gonna do NFTs - and this goes for more general commercial Qs too - it's good to be forward-looking. The work that law firms do related to crypto is often (though probably not exclusively) about using blockchain solutions to make traditional financial system functions easier - simplified clearing of cash or securities being a big one. Note though that these assets are in measure already digital, and, like most digital assets, very fungible. The most frequently cited real-economy application of NFTs is real estate, with the potential to streamline land registration. There might be something there with other assets that are susceptible to specific performance (particularly physical art), so this is worth thinking about.
