Someone knew.<\/p>\n

Three days before a critical vulnerability in Zcash\u2019s privacy architecture was publicly disclosed, five wallets quietly opened $72 million worth of short positions on Hyperliquid. Perpetual futures volume for ZEC surged 12-13 times normal levels on May 26, according to blockchain analytics firm Allium Labs. When the bug hit the news on May 29, ZEC\u2019s price cratered 38-45% within 24 hours, and those five wallets walked away with roughly $3.43 million in profit.<\/p>\n

The bug, the shorts, and the timeline<\/h2>\n

On May 26, ZEC futures trading volume on Hyperliquid exploded well beyond anything resembling normal activity. Five specific wallets opened massive short positions totaling approximately $72 million. At this point, there was no public knowledge of any vulnerability in the Zcash protocol.<\/p>\n

Three days later, on May 29, security researcher Taylor Hornby publicly identified a critical flaw in Zcash\u2019s Orchard shielded transaction pool. The vulnerability affected the zero-knowledge proof circuit, which is the cryptographic backbone that makes Zcash\u2019s privacy features actually work.<\/p>\n

The bug wasn\u2019t new, either. It had existed since Orchard\u2019s activation in May 2022, meaning it sat undetected for roughly four years.<\/p>\n

Once the disclosure went live, ZEC\u2019s price plummeted. The token fell to lows of roughly $247 to $265, representing a 38-45% decline in just 24 hours. The five wallets that had positioned themselves short before the news closed out their trades with $3.43 million in gains.<\/p>\n

An emergency hard fork was executed on June 1-2 to patch the vulnerability.<\/p>\n

Trading frenzy on Hyperliquid<\/h2>\n

On June 5, Hyperliquid recorded $560 million in ZEC trading volume in a single hour. Allium Labs flagged the pre-disclosure volume spike as a clear anomaly, with trading activity ballooning by more than a factor of 12 in the days before the market-moving event.<\/p>\n

The on-chain data doesn\u2019t prove insider trading in a legal sense. But the pattern,…<\/p>\n
