Spark Protocol's decision to delist low-utilization assets like rsETH in January has been validated amid the current market crisis. According to monetsupply.eth, Spark Protocol's strategy lead, the protocol's actions to tighten collateral and functionality scope, despite initial dissatisfaction from "ETH circular leverage" users, have proven prudent. Spark Protocol has maintained high maximum interest rate caps on its ETH lending market, which has allowed it to retain sufficient ETH withdrawal liquidity. In contrast, Aave, which lowered its ETH borrowing rates to 10% or less, is facing liquidity shortages and freezes across Ethereum mainnet and other chains like Arbitrum and Base. monetsupply.eth warned that with ETH as a core collateral asset, reaching 100% market utilization could prevent proper collateral liquidations, posing systemic risks. Aave's liquidity constraints could lead to significant bad debt if ETH prices drop by 15%-20%, exacerbated by potential fallout from the rsETH incident.
