CoinEx News: ZEC fell more than 40% over 24 hours and broke below $350 on June 5 after Zcash’s Orchard vulnerability disclosure escalated into a confidence shock. ZODL said security researcher Taylor Hornby discovered the Orchard soundness bug on May 29 using Anthropic’s Claude Opus 4.8 AI model and custom auditing tools, while fixed zcashd and zebrad releases are now available and no exploitation or unauthorized value creation has been found.

BitMEX co-founder Arthur Hayes’ full ZEC exit turns the patched bug into a narrative repricing: privacy-chain demand is now trading on investor tolerance for residual supply-audit uncertainty, not only on whether the code has been fixed.
