PANews 5月30日消息，据The Block报道，一名交易者因Chainlink预言机的VWAP机制异常损失超50万美元。事件源于以太坊上MEV机器人JaredFromSubway在Curve的deUSD/USDT池进行21万美元大额交易，导致低流动性市场中deUSD价格短暂飙升至1.03美元。该价格波动通过Chainlink预言机传导至Avalanche网络，触发Euler借贷平台上用户的头寸清算。

Chainlink支持者“ChainLink God”解释称，该预言机采用全市场VWAP定价机制，deUSD已被标记为“高风险资产”。Chaos Labs创始人Omer Goldberg指出，在流动性不足的池子使用VWAP存在设计缺陷，建议对稳定币实施价格上限或抗异常值算法。数据显示，deUSD总供应量1.85亿美元中，Avalanche链上流通4270万美元。
