I have seen it also ,there are many of scam Defi project running over here and there also in Uniswap exchange .Most of the scam project making hype so we need more careful to choose Defi project before invest .
Obviously, this was due to the scammers who took their opportunity to create a DeFi project, because they also knew that DeFi was in a good trend, so they took the opportunity to do so in order to make a profit through investors.
