Zcash (ZEC) climbed back to around $432 on Thursday, gaining roughly 6% as traders shrugged off the fallout from a previously undisclosed bug in the protocol's Orchard shielded pool. The cryptocurrency had fallen about 30% over the past month following the bug's disclosure, but the day's price action suggests the immediate panic is fading — even as on-chain activity tells a more cautious story.
Bug disclosure and the June 5 outflows
The Orchard pool vulnerability was made public on June 5, though developers had patched it days earlier. On that same date, roughly 157,931 ZEC left the shielded pools — the largest single-day outflow since January 2. The mass exit rattled holders and drove spot volumes on centralized exchanges to $3,756.7 million on June 6, far above the 30-day daily average of roughly $899.5 million. Decentralized exchange trades for wrapped ZEC also hit 17,401 on June 5, the highest in 60 days.
But the exodus slowed quickly. By June 8, net spot flows had turned positive as buyers stepped back in, according to data from the network. The brief surge in activity suggests that while the bug spooked some participants, others viewed the dip as a buying opportunity.
Network activity tells a different story
Despite the price rebound, the Zcash network isn't showing signs of a recovery in daily use. On-chain transactions have been on a falling 7-day trend, down 3,771 compared with the prior week, after peaking at 38,515 on May 15. Active addresses currently sit near 5,000 daily, well below the brief spike to 10,422 seen on June 5 when holders rushed to move funds.
Zooming out to the past 90 days, the divergence between price and usage is stark. ZEC is up about 106% over that period, but on-chain transactions fell roughly 11% and active addresses grew less than 9%. That pattern — rising price with lagging network activity — has historically raised questions about short-term speculation versus genuine adoption.
Whales split: big holders add, mid-tier whales trim
Large ZEC holders are sending mixed signals. The top 100 addresses — often called mega whales — increased their holdings by about 4% over the reporting period. But standard whales, typically defined as the top holders excluding the top 100, cut their positions by roughly 8.9%. That split suggests the biggest players are betting on a recovery while the next tier is locking in profits or cutting losses.
Sentiment data offers another reason for caution. Positive mentions for ZEC are at their lowest since May 2, meaning the social media buzz that often accompanies rallies is notably absent. Without that enthusiasm, sustaining the price rebound may prove harder.
The immediate question is whether the Orchard patch can fully restore trust in the shielded pools — the core privacy feature that distinguishes Zcash. If outflows resume, today's gains could vanish quickly. For now, traders are watching whether volumes stay elevated or drift back to the quiet levels that preceded the bug.”
