Bearish zcash bets hit record high as privacy token's price crashes
Zcash fell as much as 50% after a newly disclosed Orchard bug raised supply concerns, while bearish futures bets hit a record.
Intelligence analysis by GPT-5.4 Mini
Zcash's selloff looks spot-led, not a leverage wipeout, even as traders piled into bearish futures bets. The catalyst was a privacy-pool vulnerability that could not be cryptographically proven as never exploited, leaving a cloud over ZEC's supply integrity.
Zcash had a hidden hole in a privacy part of its system, and that made people worry fake coins might have been made. When people got scared, they sold a lot, and many traders also bet the price would keep falling.
Analysis
What happened
Zcash (ZEC) plunged after Shielded Labs disclosed a vulnerability in the network's Orchard privacy pool. The issue, which had existed since Orchard launched in May 2022, was patched in an emergency fix by June 1 after being found by security engineer Taylor Hornby using Anthropic's Opus 4.8 model.
Why the selloff looks different
The token fell as much as 50% in 24 hours, but forced liquidations were relatively limited at about $118 million, according to CoinGlass. That is small compared with the size of the move and suggests the decline was driven mainly by spot selling rather than a futures cascade. Open interest in ZEC futures rose to a record high in token terms, showing traders were opening new positions even as the price fell.
Bearish positioning
The long/short ratios on major venues skewed bearish. Binance showed sub-1 ratios across retail, whale accounts, and whale positions; OKX was even more negative. That setup means many traders are betting the slide continues. If selling eases and the price steadies, those shorts could be forced to buy back, which could create a sharp bounce.
The unresolved issue
The deepest problem is not the bug itself, which is now fixed. It is the uncertainty around whether it was ever exploited. Shielded Labs said there is no cryptographic way to prove that no counterfeit ZEC was created before the patch, so the token's supply narrative remains under a cloud. Arthur Hayes, chief investment officer of Maelstrom, said he sold his entire zcash position after the disclosure.
Key points
- Zcash fell as much as 50% in 24 hours after Shielded Labs disclosed an Orchard privacy-pool vulnerability.
- Forced liquidations were about $118 million, which points to spot selling rather than a leverage cascade.
- Open interest in ZEC futures reached a record high in token terms as traders added new positions.
- Long/short ratios across Binance and OKX skewed bearish, showing crowded short positioning.
- The biggest concern is uncertainty over whether the flaw was ever exploited before the emergency patch.
If the patch holds and confidence returns, the market may refocus on Zcash's long-term privacy use case rather than the bug. Because many traders are heavily short, a period of price stability could force some of them to buy back, pushing the price up quickly.
The main downside is that no one can prove the flaw was never exploited, so suspicion about ZEC's supply could linger. If that uncertainty keeps holders selling, the token could stay under pressure even after the technical fix.
