Key Takeaways
Anthropic’s restricted Mythos AI audited the complete Zcash protocol at Shielded Labs’s request and located no new vital bugs as of June 12, 2026.ZEC trades round $411 to $416 on June 13, recovering from June 5 lows close to $300 after the Orchard circuit bug was patched by way of NU6.2.Shielded Labs and Zcash contributors proceed safety hardening work forward of the Ironwood improve, concentrating on late July 2026.
Zooko Thanks Anthropic After Full Protocol Audit
The assertion got here straight from Zooko, the web deal with for Zooko Wilcox-O’Hearn, pc safety specialist, cryptographer, and co-creator of Zcash. Writing on X, he stated:
“Thanks, Anthropic, for serving to shield Zcash customers. At Shielded Labs’s request, they ran a safety audit of Zcash with Mythos. It didn’t discover any extra critical bugs within the Zcash protocol. Shielded Labs and others are persevering with safety hardening work. Keep tuned for updates.”
The submit arrived one week after the general public disclosure of a vital soundness bug within the Orchard shielded pool, which had triggered a 38% to 50% worth collapse in ZEC inside 48 hours of going public on June 4 and 5.
What Mythos Is and Why It Issues
Anthropic’s Mythos Preview is the corporate’s most superior AI mannequin, launched in April 2026 as a part of its Undertaking Glasswing defensive safety initiative. Not like the Claude fashions out there to most of the people, Mythos isn’t publicly accessible. Anthropic restricts entry to a restricted group of trusted companions, together with main know-how corporations and significant infrastructure tasks, exactly due to its capabilities in autonomous safety analysis, zero-day vulnerability detection, and complicated codebase evaluation.
Shielded Labs, the nonprofit group supporting Zcash improvement, secured entry to Mythos and directed the audit on the total Zcash protocol.
The Orchard Bug That Triggered the Disaster
The Mythos audit follows a harrowing episode for Zcash holders. In late Could 2026, safety researcher Taylor Hornby, working beneath contract with Shielded Labs, used a customized AI auditing framework constructed round Claude Opus 4.8 to establish an under-constrained circuit ingredient within the Orchard shielded pool’s zero-knowledge proof system. The flaw had existed since Orchard’s activation in Could 2022 and had gone undetected for about 4 years regardless of prior knowledgeable audits.
The bug represented a supply- inflation danger. An attacker with ample technical information might have minted counterfeit ZEC contained in the privateness pool, completely undetectable on-chain.
Builders moved quick. A delicate fork on June 2 quickly disabled all Orchard actions. A tough fork on June 3, the NU6.2 improve, activated a corrected circuit and re-enabled Orchard with no chain break up.
Public disclosure on June 4 and 5 nonetheless triggered a pointy selloff. ZEC fell from a pre-disclosure worth close to $624 to intraday lows approaching $300 on some exchanges, wiping billions from the market cap in hours.
What the Clear Audit Means for ZEC Holders
The Mythos outcome doesn’t shut the ebook on safety work. Zooko was specific that efforts proceed. Shielded Labs and different contributors are urgent ahead with safety hardening, which incorporates formal verification of the Orchard circuit, extra AI-assisted auditing, and plans to rent a Head of Safety and a devoted cryptographer.
The Ironwood improve, concentrating on activation in late July 2026, will deploy a brand new shielded pool utilizing the corrected Orchard circuit and implement stricter turnstile accounting to permit impartial provide verification. The Ironwood proposal straight addresses lingering questions on provide integrity that the Orchard bug launched.
ZEC Worth Holds Above $400
As of June 13, ZEC trades within the $411 to $416 vary, stabilizing above the $400 assist stage after recovering 45% to 80% from June 5 lows. The market cap sits close to $6.9 to $7.0 billion. ZEC ranks within the prime 12 to fifteen cryptocurrencies by market cap at present costs.
The Mythos audit outcome, mixed with the velocity of the emergency repair and the Ironwood roadmap, has supported the restoration. Worth stays effectively under the June 4 peak close to $624, with the subsequent main catalyst possible tied to progress on Ironwood.
Safety Work Continues
Zooko’s assertion closed with a transparent sign: this isn’t a declaration of completion. “Keep tuned for updates,” he wrote, pointing to an ongoing program that now consists of a few of the most superior AI safety tooling out there anyplace.
For ZEC holders, the clear Mythos audit supplies significant reassurance after a turbulent two weeks. The protocol’s strongest out there reviewer discovered nothing new. The crew remains to be wanting.
