Investing in Art (NFT market) is Halal

I came across this that you can invest in Arts (NFT market)

Is this Halal?

Wasalam

May Allah bless you.
If the content of the NFT is shariah compliant, then yes you can.

And Allah knows best!

Does this go for investment of paintings through mastworks.com too?

Anything to do with painting and drawing, the content must not contravene shariah principles.
