Zcash experienced a sharp sell-off due to a vulnerability in its private transaction pool, which could allow for the forging of ZEC. After the news broke, ZEC briefly fell below $300, wiping out billions of dollars in market value.
Vulnerability triggers sell-off
This issue stems from a four-year-old vulnerability in the Zcash network, related to its private transaction pool. The developers have patched it this week, but the market is most concerned about whether the vulnerability was exploited before it was fixed.
Over the past month, ZEC's price rose from below $200 in March to around $675 by the end of May. Following this, a panic sell-off quickly emerged, with ZEC dropping more than 35% within 24 hours and briefly falling over 40% from its high.
The market is concerned about difficulty in verification.
Analysts note that what truly suppresses the price is not the vulnerability itself, but the inability to immediately confirm whether it has been exploited. If counterfeit minting exists and cannot be fully proven with existing mechanisms, the market will apply a higher risk discount.
Nansen research analyst Nai Sondergaard believes that this price reaction reflects uncertainty rather than mere technical flaws. Bitwise research analyst Ish Asad also noted that, at the time of the announcement, the privacy narrative was gaining momentum, with ZEC having already significantly outperformed Bitcoin and other major cryptocurrencies.
Still the strongest asset of the year
Despite the recent sharp decline, ZEC has still risen over 580% over the past year. Before this downturn, it approached $700 and remained one of the strongest-performing assets in the crypto market.
Nansen’s Jake Kennis believes that ZEC may need a stronger privacy coin narrative, protocol-level catalysts, or a reallocation of capital toward privacy assets to reclaim most of its lost ground. Arthur Hayes also stated on social media that he has sold his entire ZEC position but still believes there is long-term demand for privacy assets.
