Decentralized exchange (DEX) dYdX encountered an unexpected setback on November 17 when it was compelled to tap into its insurance fund to cover losses amounting to $9 million from user liquidations. dYdX founder Antonio Juliano attributed these losses to what he described as a "targeted attack" directed at the exchange.
Reports emerging from the dYdX team, shared via X (formerly Twitter), revealed that the v3 insurance fund was utilized to address gaps in the market clearing process for the YFI token associated with Yearn Finance. The YFI token, which had witnessed a significant surge of over 170% in the preceding weeks, suddenly dropped by 43% on November 17. This sudden price downturn raised concerns within the cryptocurrency community, sparking fears of a potential exit scam.
The attack primarily focused on liquidating long positions associated with dYdX's YFI token, resulting in the liquidation of positions valued at nearly $38 million. Juliano asserted that the trading losses experienced by dYdX and the abrupt decline in YFI prices were the outcomes of market manipulation. He stated, "This is clearly a targeted attack on dYdX, including market manipulation of the entire $YFI market. We are investigating with multiple partners and will be transparent about our findings."
Juliano further disclosed that the v3 insurance fund retains $13.5 million, reassuring users that their funds remained unaffected by the incident. Despite this assurance, he emphasized the necessity for a comprehensive assessment of their risk parameters. Juliano added that necessary adjustments would be made to v3 and potentially dYdX Chain software following the review.
The substantial impact of the lucrative trade led to a depletion of over $300 million from the YFI token's market value, prompting speculation within the community about potential insider activities in the YFI market. Some users suggested that approximately 50% of the YFI token supply is held across 10 wallets controlled by developers. However, data from Etherscan indicates that several of these holders are cryptocurrency exchange wallets.
