Zcash (ZEC) experienced a sharp selloff over the past 24–48 hours, with the privacy-focused cryptocurrency sliding to $373.51 as of June 29, 2026, down 6.3% in the last 24 hours and 15.43% over the past 7 days. The decline reflects broader market concern tied to reports of a critical vulnerability affecting the protocol's shielded pool, though official confirmation from the Zcash Foundation or Electric Coin Company remains unavailable in current sources.
