Arthur Hayes, the co-founder of BitMEX, confirmed today that he liquidated his entire Zcash (ZEC) position after a protocol bug in Orchard Pool. The core bug in Zcash’s protected transaction layer has been publicly disclosed, worsening an already difficult few weeks for ZEC.
The move completes the complete liquidation of its self-proclaimed “Holy Trinity” wallet, which previously included HYPE and NEAR tokens.
The central question the market is asking now is not whether Hayes was right to step down, whether the bug is real, and whether the risk is documented, but whether this is a cold assessment of protocol risks or a reactive reaction after a vulnerability shook his belief in the privacy coin category.
The evidence leans heavily toward the former. This distinction is important for anyone trying to read this output as a signal.

The Orchard Pool Bug: What the Vulnerability Really Means for ZEC
The Orchard Pool is Zcash’s next-generation shielded transaction circuit, introduced with the NU5 upgrade in May 2022.
It replaced the old Sapling pool and brought trustless zk-SNARKs through the Halo 2 testing system, no trusted setup required. The pool exists specifically to enable completely private transfers, and its cryptographic strength is not a feature; This is ZEC’s entire value proposition.
The bug, identified on May 29, 2026 by security engineer Taylor Hornby of Shielded Labs using formal AI-assisted methods including Anthropic’s Claude Opus 4.8, was an insufficient constraint in the multiplication of elliptic curves inside the system. halo2_gadgets box.

Simply put, counterfeit entries could theoretically bypass the circuit’s validity checks and produce counterfeit ZECs that would still pass Orchard’s check.
An emergency hard fork was activated on June 3, 2026, fixing the flaw. But the window from NU5 activation in 2022 to the June 2026 patch represents nearly four years in which the bug existed undetected, surviving multiple expert audits.
Here’s the part that matters to holders: Due to Orchard’s privacy architecture, it is cryptographically impossible to prove that a counterfeit ZEC was never issued during this window.
No evidence of exploitation exists, but the inability to attest to the full integrity of the supply is not a footnote; This is a fundamental crack in the strong monetary narrative that Electric Coin Co. has built around ZEC.
Hayes leaves Zcash: reaction to protocol risk or the same pattern repeats itself?
Hayes had publicly flagged Zcash as a high-conviction stock, part of the “Holy Trinity” alongside HYPE and NEAR, a trio he billed as his asymmetric altcoin bets.
It had already crossed HYPE and NEAR before turning to ZEC, a sequencing that some interpret as methodical de-risking rather than panic.
ZEC’s release followed the public disclosure of the Orchard bug and the June 3 hard fork, meaning Hayes moved after the vulnerability was known, not before.
His justification was direct: “The likelihood of an unauthorized strike is extremely low, but this cannot be proven cryptographically impossible,” he wrote. And further: “The privacy narrative against AI, governments and big tech demands perfection, a standard that the bug has undermined.”
This framing is not an excuse for traders. This is a thesis statement. Hayes has long been ZEC because privacy coins occupy a unique ideological and technical niche, and that niche requires cryptographic certainty that Orchard can no longer provide without reservation.
The pattern here is familiar to anyone who has followed Hayes’ public portfolio moves. A new conviction, public approval, and then a clean exit when the underlying thesis breaks down. Whether it’s disciplined risk management or the “shill, pump, dump, repeat” cycle that this site has previously documented is a matter of judgment, but the Orchard bug gives this release a fundamental rationale that’s harder to dismiss than most. He continues to hold Worldcoin (WLD), which was never part of the Trinity framework.
ZEC prices and market structure: the damage is real
ZEC fell 30-36% from recent highs following public disclosure of the bug, falling from over $600 to around $390, wiping out over $3 billion in market capitalization.
The move broke the 20, 50, and 100-day EMAs in order, with traders now viewing the 200-day EMA support near $367 as the next critical level.
Hayes’ exit itself occurred on normal trading volumes, suggesting that his position did not mechanically move prices; the market was already factoring in the protocol risk before its announcement was made.
The structural reading is bearish until the $430-$450 zone is reclaimed at the close. Below $367, ZEC enters uncharted technical territory with limited historical reference support.
