Delphi Digital：Aave 三大核心市场存在结构性问题，年化无谓损失约 5200 万美元
ChainCatcher消息，Delphi Digital 在最新发文中指出，WETH、USDT 和 USDC 是 Aave 以太坊市场上最大的三个借贷市场，占总借款量的 89%。这三个市场的供给利率比借款利率低约 25%-35%，由此产生的年化无谓损失（Deadweight Loss）约为 5200 万美元，接近 Aave 第一季度年化收入的一半。即使完全取消储备因子（Reserve Factor），仍存在约 3600 万美元的损失。
Delphi 认为，Aave 的 peer-to-pool 模型在此存在明显结构性缺陷。4月18日 KelpDAO 桥接被攻击事件进一步暴露了这一问题。攻击者利用 2.92 亿美元 rsETH 在 Aave 进行杠杆借贷，导致 Aave 产生近 2 亿美元坏账，WETH 等主要市场 100% 利用率冻结长达 5 天。
