Debate sparked by MYX’s $170M surge and 135% price spike: Sybil attack or legitimate airdrop?

Bubblemaps, a blockchain analytics firm, has recently raised concerns about what they claim to be the largest Sybil attack in the history of cryptocurrency. This attack targeted the MYX token airdrop on the decentralized derivatives platform MYX Finance. Bubblemaps identified 100 new wallets that received funding with similar amounts of BNB from OKX on April 19, 2025. These wallets later claimed 9.8 million MYX tokens during the airdrop on May 7, which accounted for 1% of the total token supply. The estimated value of these claimed tokens amounted to $170 million.

In response to these claims, MYX Finance refuted the allegations and maintained that the airdrop rewards were distributed based on legitimate trading volume and contributions made by liquidity providers. The platform admitted to allowing address changes for high-volume users pre-launch but emphasized its commitment to promoting user engagement. However, critics dismissed MYX Finance’s response as ambiguous and potentially generated by artificial intelligence. Additionally, the platform highlighted anti-Sybil measures in its “Cambrian” campaign, but these measures were not evident in the broader airdrop.

Speculation surrounding insider trading increased following the airdrop and a subsequent unlock of 39 million tokens on September 8, 2025. During this unlock window, $2.15 million worth of MYX tokens were swiftly transferred to exchanges, coinciding with a 135% surge in token price over 24 hours. This surge in price aligned with a notable increase in perpetual futures trading volumes, which reached $4.23 billion, and reflected a doubling of open interest to $262.1 million. Reports also indicated substantial short liquidations exceeding $10 million in a single day, suggesting coordinated buying activity.

Critics have drawn attention to the significant discrepancies in MYX’s fully diluted valuation (FDV) compared to its total value locked (TVL). Within 48 hours of the airdrop, MYX’s FDV skyrocketed to $17 billion despite a TVL of just $31.87 million and monthly revenue totaling less than $500,000. Analysts argue that this rapid growth does not align with the project’s underlying fundamentals, pointing to inflated trading volumes and concentrated ownership. Notably, 12% of MYX tokens are still uncirculated, with one address holding a substantial amount of tokens at the peak.

This incident underscores broader vulnerabilities within the decentralized finance (DeFi) space. A report by Chainalysis highlighted the prevalence of wash trading in 2024, amounting to $2.57 billion in DEX volume. Additionally, pump-and-dump schemes accounted for 4.52% of market activity in 2024, up from 3.59% in the previous year. The MYX case underscores the necessity for increased anti-Sybil measures and transparency in token distribution models to prevent such manipulative activities.

With regulatory scrutiny on the rise and calls for enhanced oversight of DeFi projects, the industry faces growing challenges. The U.S. Commodity Futures Trading Commission (CFTC) has initiated investigations into market manipulation cases, signaling a shift towards increased regulatory scrutiny. MYX Finance’s response and commitment to balancing user participation with future anti-Sybil measures may provide a roadmap for navigating these challenges. For investors, this incident serves as a reminder of the risks associated with low-liquidity assets and the importance of closely monitoring on-chain activity and unlock schedules.
