Their concept looks new and interesting but it depends how sustainable it will be. That is why defi lost steam these days bcoz they offered high APY with no sustainable plans to ensure that the project continues being profitable for long. You cannot a huge supply for yield farming with insane APY like 400% and expect price to be stable.
Yeah, but with their dividend model, I think it has the potential to last as it is backed by real assets, which means its token price will have strong support on the open market.
