- ZEC price has rebounded to approximately $492 following a sharp 50% decline to $299 after bug revelation

The Zcash ecosystem has officially scheduled its Ironwood mainnet upgrade for July 28, 2026. According to core developer Sean Bowe, the activation will occur at block height 3428143, with full backing from every major organization participating in the network.
This upgrade directly addresses a critical vulnerability discovered in May within Zcash’s Orchard pool—the primary privacy-focused transaction layer. The flaw theoretically enabled the undetectable creation of counterfeit ZEC tokens.
Ironwood will permanently deactivate the Orchard pool while blocking any further transactions within it. A newly designed shielded pool will take its place, incorporating formal verification protocols, independent security assessments, and quantum-resistant note structures.
As users migrate their holdings from the deprecated Orchard pool to the new Ironwood infrastructure, all transfers must clear an accounting verification point. This mechanism could potentially expose whether any fraudulent tokens were actually minted during the vulnerability window.
Shielded Labs initially advocated for postponing the launch, citing insufficient preparation time for cryptocurrency exchanges, wallet providers, and mining operations. The confirmed July 28 date represents a one-week extension from the initially proposed July 21 activation.
Token Value Rebounds Following Sharp Correction
The ZEC token experienced significant selling pressure immediately after the Orchard vulnerability became public on June 3. Prices tumbled 50% from $602.68 down to a bottom of $299.25. The token has since recovered substantially, currently trading near $492.61.
FXStreet analyst Vishal Dixit observed that ZEC maintains positions above both its 50-day exponential moving average at $457 and its 200-day EMA at $388. He pinpointed the 78.6% Fibonacci retracement level at $520 as the subsequent resistance target to monitor.
Sean Bowe’s announcement regarding the activation block height on X platform sparked renewed market engagement. The confirmation from all participating organizations strengthened confidence in the upcoming transition.
Futures Markets Reflect Growing Trader Confidence
Data from CoinGlass indicates that ZEC futures Open Interest expanded by 18% over a 24-hour window, reaching $914.91 million. Simultaneously, trading volume increased approximately 10% to $1.66 billion during the identical timeframe.
The funding rate registered at 0.0105% positive, demonstrating that traders are accepting premium costs to maintain long exposure.
In a separate development, Zcash achieved a significant supply threshold this week. According to a Monday announcement from ruZCASH, the network has now distributed over 80% of its maximum 21 million ZEC supply cap, with 16,806,723 tokens currently in active circulation.
