CowSwap hack after BTC rally sends COW to ~$0.21
Ethereum DEX CowSwap was hit by a reported frontend vulnerability, triggering an urgent security warning from blockchain intelligence firm Blockaid. Users are advised not to connect wallets to the CowSwap website and to revoke existing wallet approvals immediately.
Following the news, CowSwap’s native token COW sold off sharply, falling to around $0.2137 (near $0.21). After the initial dump, the price decline paused, but traders are monitoring for further confirmation as investigations continue.
Blockaid flagged a “serious” frontend issue. The article notes that such problems can be validated quickly in DeFi, and that protocol-level threats often lead to rapid losses unless incident response and communication are fast. CowSwap’s intent-based auction model is designed to reduce typical MEV pain (front-running and sandwich attacks) and it helps match opposing trades without direct liquidity-pool interaction.
However, CowSwap’s popularity on Ethereum (reported as among the top 10 most-used DEXs) can also amplify risk during attacks due to a larger user base. The article says authorities have not yet detailed how the hack occurred or the damage scope, and it emphasizes watching official updates for remediation steps.
For traders, this is a near-term risk event for COW liquidity and Ethereum DeFi sentiment, with immediate “wallet-approval” hygiene likely to influence user behavior until patches are deployed.

这是一次面向用户交互的“前端漏洞/疑似被攻破”事件，直接指向 CowSwap 的安全性与资产被未授权操作的风险。类似 DeFi 平台被曝存在可利用漏洞时，短期通常会出现：1) 相关代币（此处为 COW）流动性下降与抛压；2) 用户先撤授权、后观察，成交与锁仓意愿走弱；3) 市场在缺乏明确修复时间表前维持风险溢价。
本次 CowSwap 的 COW 已出现接近 0.21 美元的快速回撤，说明风险定价已开始。若后续确认存在真实利用链路、资金损失扩大或修复延迟，情绪可能进一步恶化，形成更长的下行或高波动区间。相反，若官方迅速给出根因、补丁与补偿方案，短期抛压或会缓和，但“黑客/漏洞叙事”往往会在较长时间内压制估值与交易活跃度。
因此总体预期偏空：短期看 COW 及以太坊 DeFi 板块情绪承压；长期则取决于 CowSwap 的安全响应速度与复盘透明度。
