The list of Project Glasswing members is growing. Payward, the parent company of crypto exchange Kraken, has officially joined the Anthropic-backed initiative. This move makes Payward the first crypto entity to secure access to Claude Mythos 5.
Mythos 5 is Anthropic’s most advanced artificial intelligence model designed specifically for cybersecurity. The machine is tasked with reading and analyzing code with logic similar to how an attacker works, but operating nonstop at machine scale.
The tracking capacity of this model has been field-tested. In an April 2026 test, Claude Mythos identified 271 vulnerabilities in the Firefox browser during Mozilla’s testing session. Now, Payward will leverage the same computing power to scan their systems for security flaws that endanger user assets.
Reversing Defense Asymmetry
Every vulnerability finding captured by Mythos 5 will be immediately sent to Payward’s internal security team for follow-up. If the machine detects flaws in third-party open-source software, Payward is committed to reporting them to the respective project maintainers.
This information-sharing practice paves the way for protection that extends beyond Kraken’s internal boundaries, potentially securing the broader crypto ecosystem.
Arjun Sethi, Co-CEO of Payward, highlighted the asymmetric reality in cybersecurity. “Attackers only need to find one vulnerability. Defenders must find all vulnerabilities, every day,” he said. This frontier AI is seen as the first tool capable of reversing that asymmetry.
A Push That Bore Fruit
Payward’s entry into Project Glasswing places them on par with tech giants. Since its initial launch in April 2026 and expansion two months later, its members have discovered thousands of high-level and critical vulnerabilities. The roster of participants includes major names such as Amazon AWS, Apple, Google, Microsoft, and financial institution JPMorganChase.
The United States government has also made Mythos 5 available to domestic organizations operating critical infrastructure. The decision to open the door for crypto companies came after industry pressure. Previously, more than 40 Bitcoin and crypto companies - including Ark Invest, Coinbase, Block, and BitGo - released an open letter asking AI lab developers to open access to their technology for external security researchers.
That access is now in hand. The next stake shifts from merely finding vulnerabilities to how responsive human teams are in patching the weak points reported by their guardian machines. Reported by CoinDesk.
