Wu said that he learned that Spark’s strategy director, monetsupply.eth, stated that Spark delisted rsETH and other low-usage assets in January, and has continued to tighten the range of eligible collateral and the feature set. This is also why the SparkLend ETH market maintains relatively high maximum interest rates, even though this decision has not been accepted among ETH loop-lending users, and may have caused a large amount of business and revenue to move from Spark to Aave. However, in the current situation, this shows the approach is cautious and correct: SparkLend still has ample ETH withdrawal liquidity, while Aave’s markets across multiple networks are already seeing liquidity shortages.
