Zcash Climbs 80% Since June 5 as Traders Shrug off Orchard Bug Fears

The Orchard Vulnerability

Privacy coin Zcash (ZEC) surged on Tuesday, jumping 11.3% to $478 as it maintained a steady recovery that began shortly after it plunged to just under $265. At the time of writing (5:32 a.m. EST), the privacy coin’s latest climb pushed its gains since June 5 to approximately 80% and saw ZEC’s market capitalization reclaim the $8 billion threshold.

The coin, alongside rival monero, was one of a handful of altcoins that logged gains exceeding 5% even as bitcoin dipped below the $63,000 threshold. ZEC’s surge above $470 on June 9 resulted in $11.5 million in short positions on the coin being wiped out in 24 hours, compared with $2.43 million in liquidated long bets.

While Zcash has since wrestled back its top-dog status from chief rival Monero, the asset is still trading at a steep discount compared to its pre-June 5 peak of just over $600. Before the correction, ZEC was riding a powerful wave of momentum, fueled by a resurgence in the crypto-privacy narrative and high-profile endorsements from industry heavyweights like Arthur Hayes. However, that bullish trajectory ground to a sudden halt. The catalyst for the reversal was the unsettling discovery of a critical vulnerability within Zcash’s Orchard shielded pool—a zero-knowledge security flaw that had quietly lay dormant since 2022.

Despite this, supporters of the privacy coin believe the uncovering of the bug has not damaged ZEC’s long-term appeal. Posting on X, Eunice Wong insisted there is an extremely low likelihood an exploit was executed and said traders who offloaded their holdings had overreacted.

“Long-term thesis hasn’t changed. In an AI-driven world where every transaction is tracked, financial privacy will become the scarcest asset, and ZEC is still one of the strongest privacy plays in crypto. Catching this falling knife is going to look like a genius move,” Wong wrote.

Matthew Brienen, managing partner at Cryptocharged, said while he recently reduced his ZEC holdings, it was purely a risk-management decision rather than a change in conviction. Nevertheless, he offered an explanation for why caution is warranted even if there is no proof that ZEC was counterfeited.

“The Orchard bug isn’t a confirmed inflation event. It’s a confirmed inability to prove supply integrity. Those are not the same thing. The most important fundamental fact to remember is that turnstile accounting is not the same as proving Orchard balances are legitimate. You can track what entered. You can track what exited. That doesn’t prove every claim inside the pool was valid,” Brienen explained.

He added, however, that if counterfeit Orchard notes do exist, they could remain hidden until redemption is ultimately forced. According to Brienen, the recent price action suggests that is exactly what the market is trying to price in.
