Crypto exchange Kraken is under renewed scrutiny as blockchain investigator ZachXBT flagged suspicious 'Memecore' token flows, suggesting potential insider-driven activity rather than organic market demand. This comes despite the exchange's parent company, Payward, publicly showcasing its strong collaboration with global law enforcement in a major fraud crackdown.
Payward, Kraken's parent, played a key role in 'Operation Atlantic,' a multinational initiative announced on April 20, 2026, targeting cryptocurrency fraud. The operation was led by the United Kingdom’s National Crime Agency (NCA) and jointly coordinated with the US Secret Service, Ontario Provincial Police, and the Ontario Securities Commission. The collaborative effort uncovered more than $45 million in suspected criminal proceeds and resulted in the freezing of over $12 million, while identifying upwards of 20,000 potential victims across several countries.
The fraud at the center of the operation utilized 'approval phishing,' a tactic where victims are tricked into granting malicious smart contracts access to their wallets. Payward's security team actively scanned for affected clients, issued direct notifications, and fulfilled data requests from authorities. Notably, the company dispatched personnel to the NCA's London headquarters to work side-by-side with investigators, highlighting a shift towards exchanges acting as active allies in real-time crime disruption.
However, this narrative of enforcement support contrasts sharply with rising concerns about Kraken's internal due diligence for token listings. The allegations around 'Memecore' flows point to a potential gap between the exchange's public stance on security and its internal listing standards, placing pressure on Kraken to balance rapid growth with transparency and user protection.
