The privacy-focused cryptocurrency Zcash has undergone a recent artificial intelligence-assisted security audit that reportedly found no serious vulnerabilities in its core protocol, according to its founder.
Zcash creator Zooko Wilcox said the review, carried out using Anthropic’s Claude Mythos AI system, did not identify any critical or high-risk flaws in the network’s design, offering reassurance to developers following a recent technical incident.
AI Audit Commissioned by Swiss Non-Profit
The assessment was commissioned by Shielded Labs, a Switzerland-based organization that supports ongoing development of Zcash privacy technology.
According to Wilcox, the AI-assisted audit concluded that the protocol’s architecture remains structurally sound, with no additional major bugs detected beyond previously known issues.
The findings were shared publicly via social media following growing industry interest in the role of AI tools in blockchain security analysis.
Recent Shielded Pool Vulnerability Raised Concerns
The audit follows a recent disruption involving Zcash’s shielded transaction system.
On June 3, developers temporarily suspended Orchard transactions after identifying a vulnerability in the privacy layer of the network.
The issue was later resolved through an emergency software update released the same day, restoring normal functionality.
Developers said the incident stemmed from a previously undiscovered flaw in the Orchard shielded pool mechanism, highlighting the complexity of maintaining privacy-focused blockchain systems.
No Evidence of Exploitation, Developers Say
Security researchers later determined that the vulnerability had existed for several years but showed no signs of being actively exploited.
The Zcash Foundation stated that there was no indication of unauthorized coin creation or compromise of user privacy during the period the bug existed.
A key contributor to the discovery was security researcher Taylor Hornby, who reportedly used assistance from advanced AI tools in identifying the flaw.
AI Tools Increasingly Used in Crypto Security
The incident comes amid growing adoption of artificial intelligence in blockchain security research, where AI systems are being used to scan codebases for vulnerabilities at scale.
However, the same technology is also raising concerns across the crypto industry, as attackers gain access to increasingly powerful tools for identifying weaknesses in decentralized systems.
Recent developments from Anthropic have intensified debate over the role of AI in cybersecurity.
Anthropic’s Claude Mythos Model Draws Attention
Anthropic recently introduced its Claude Mythos model, including versions such as Fable 5, which the company says has already identified thousands of high-severity vulnerabilities in widely used software systems.
While Anthropic claims the model includes safeguards and routing systems for sensitive topics like cybersecurity, critics have raised concerns about whether such capabilities could also be misused.
The company later suspended access to some versions of the model following U.S. export control restrictions tied to national security considerations.
Rising Concern Over AI-Driven Exploits in Crypto
Industry experts warn that the rapid evolution of AI-assisted hacking tools could be shifting the balance in cybersecurity toward attackers.
Immunefi CEO Mitchell Amador has previously described the situation as a “vulnerability surge,” suggesting that decentralized finance systems are increasingly exposed to sophisticated exploits.
This trend has coincided with a notable rise in crypto-related thefts, with losses reaching hundreds of millions of dollars in recent months across multiple incidents.
Crypto Security Landscape Under Pressure
Data from industry trackers shows that April alone saw approximately $634 million in losses from crypto hacks, marking one of the highest monthly totals on record.
Earlier incidents, including major exchange breaches, have contributed to growing concern about systemic vulnerabilities across the digital asset ecosystem.
As AI tools become more deeply integrated into both offensive and defensive cybersecurity operations, analysts say the crypto sector is entering a new phase of technological escalation where security, speed, and automation are increasingly intertwined.
