Having a Decentralized Derivative Exchange Problem, and I Found Aark Digital

I have been using centralized exchanges (CEX) to trade for years. So, I later decided to try a decentralized one. I switched to Cardence on the Canto network and longed some Canto because I’m a holder. It dumped, and when it got back to my entry price after a few weeks, the fee to close the position was huge, almost $100 USD.

Now, I found another one from this listing notification on my phone. Because I want to join the futures trade to earn some, I decided to read more about it and I see in their documentation that they offer an Insurance Fund feature: “This safeguards users against unforeseen failures, covering negatively valued accounts using an external liquidity pool replenished by a portion of liquidation bonuses.”

I’ve never heard of this kind of feature. What do you think about this feature, decentralized exchanges in general and about Aark Digital?
