Unfortunately many scammers are jumping on the DeFi train nowadays, and offer projects which are a direct copy of the current successful projects.
DYOR but to me this looks shady as hell
That's correct. However, does the size of the whitepaper really matter?
I think the major point of any project should be in delivering and fufiling whatever it is that was promised in their whitepaper and not whether the WP is long or small.
Unfortunately, it won't stop the people from investing projects like these because its still promoted by individuals in social meida sites. Even if the project won't be successful they still end up collecting few coins from people.
They felt there is no need for long while paper today after all explaining about borrowing and collateralization had been done in the previous DEFI. When it comes to the word defi they already are award there is no need for KYC on it and trading on its platform is sort of a protection.
