The important reason why Spark, as a rising force in this cycle, has the potential to replace AAVE is due to its strict grasp of risk control, especially in the health review of loan collateral assets. However, Spark is not one size fits all, but rather relaxed. The looseness here does not lower the threshold for collateral entry, but rather takes a higher dimensional perspective to rate the comprehensive health of multiple collateral in the overall position. Specifically, for example, I want to do a typical basis arbitrage, so I long spot on Defi and short contract on CEX. As for whether the direction is up or down, it has nothing to do with me. But because I opened positions on two different platforms, Defi protocol and CEX The exchanges can only assess the risk of my single transaction there and pay the corresponding margin accordingly, and they all believe that my operation carries huge risks when there is a shortage. However, in reality, I am just hedging, and the risk is very small. As a result, I was forced to lock up a large amount of funds as collateral. The CeDeFi margin lending product Spark Prime and Arkis, which is specifically designed for institutions, have collaborated to solve the problem of different platforms being unable to cross margin and identify external collateral, thereby identifying hedging positions, reducing margin payment requirements, and improving fund utilization. Defi and CEX, including Binance, Bybit, OKX, Hyperliquid, Pendle, Cruve, etc., can all achieve cross platform net risk calculation under the framework of Spark Prime+Arkis. So it seems that the margin payment for individual platforms has decreased, but in reality, the overall position risk has not changed. Instead, it has improved your ability to resist risks by releasing more funds.
