ChainCatcher 消息，PiggyBank 发布 6 月 6 日 LAB 事件的详细报告，称该协议于 6 月 6 日发生约 57.9 万美元净回撤，主要源于一笔 LAB 代币基差交易遭遇市场操纵。
PiggyBank 在 5 月初通过 OTC 中介买入 14.28 万枚锁仓 LAB 代币（约 10.25 万美元），同时开立永续合约空头对冲。但市场参与者将现货价格持续维持在永续合约价格之上，导致资金费率深幅负值（年化 -17,000%），对冲成本过高迫使空头平仓，损失约 47.6 万美元。相关锁仓 LAB 代币目前现货价值约 100 万美元，但因流动性差且无对冲，已从 NAV 计算中剔除。
PiggyBank 将进行结构性改革：扩大链上机制透明度，策略逻辑和资金分配将公开可验证，基差交易和资金费率套利将逐步淘汰。补偿方面，受影响用户将按实际损失获得 USDC 补偿，资金来源包括 NAV 差额、未来 LAB 出售（预计 8 月 14 日至 10 月 14 日解锁，当前价值约 100 万美元）以及未来平台收入的 50%。6 月 6 日快照中记录的所有用户均符合补偿资格。
