What would you do about nFT of someone else's art?

Quick background on my situation — any input appreciated.

NFT of someone else's art. I've been dealing with this for about 15 weeks now and the situation isn't improving.

This involves software/code I developed over the past 32 months. I do not have documentation proving my ownership and timeline.

Has anyone been through something similar? What worked for you?

Yep, this is textbook.

The trap most people fall into is having everything documented. I'd recommend keeping a detailed timeline instead.

Just want to point out — the statute of limitations might be a factor here. In some states it's as short as 1-2 years. Don't sit on this too long.
