Zcash (ZEC) experienced one of the most dramatic 48-hour periods in its history after developers disclosed a critical soundness vulnerability in the Orchard shielded pool that could have enabled unlimited counterfeit token creation. The revelation triggered a severe market selloff, with ZEC plummeting from an intraday high near $624 on June 4 to as low as $309 on June 5, before stabilizing in the $300–$400 range as of June 6, 2026.
