Could you please elaborate on the funding fee associated with dYdX? I understand that in the realm of decentralized finance and cryptocurrency exchanges, funding fees can play a significant role in maintaining liquidity and incentivizing traders. With dYdX being a prominent platform in this space, I'm curious to know what the specific funding fee structure is and how it compares to other exchanges. Additionally, I'm interested in understanding the implications it has for traders and liquidity providers using the platform. Thank you for your assistance in clarifying this aspect of dYdX's operations.
