Never heard of that DeFi platform before. But I am not involved in such activities, so I wouldn't know. A quick search over the Internet has not found any records of scams or hacks. There isn't a lot of talks about the site on Bitcointalk either. Generally, I would be very careful who I give the custody of my BTC to. More precisely, I wouldn't give it to anyone. I especially don't like hearing numbers such as 700% returns on investment and similar 'promises' and 'guarantees'.
