dYdX Identifies YFI Attacker in Pump And Dump Scheme
Leading decentralized exchange dYdX released a detailed post-mortem dissecting an elaborate market manipulation scheme involving token YFI’s 200%+ pump and 30% “crash” last week. The exchange traced activities across 100+ wallets to identify the likely perpetrator and assist law enforcement investigations.
Key Details:
- The attacker opened substantial 5x leveraged YFI longs across multiple accounts during the pump.
- Price action suggests they ignited the spike by purchasing spot YFI.
- But they failed to close positions before the crash, with most liquidated by the insurance fund.

dYdX Dissects Pump & Dump Scheme
dYdX concludes that the malicious actor did not ultimately profit from the choreographed pump and dump. YFI prices surged as the trader accumulated tokenized long exposure targeting $50 million at peak.
However, an abrupt 30% plunge left the inflated positions massively underwater. It triggered cascading liquidations of their capital by dYdX’s automated insurance fund.
Similar tactics were deployed the prior week in token SUSHI, but without losses from an ensuing crash. This suggests a pattern of deliberate manipulation to propel price runs.

Through blockchain analysis, the exchange linked activities across the swath of implicated wallets to pinpoint a specific suspect. User data enabled dYdX to contact the individual directly while furnishing findings to law enforcement.
Multiple improvements deployed enhance exchange-level protections from similar coordinated assaults:
- Revised margin policies reducing risk tolerance in illiquid markets
- Auto-adjusting initial margin rates in response to abnormal volatility signals
- Upgraded open interest monitoring and alert triggers
The episode illustrates the growing sophistication of on-chain fraud tactics. However, dYdX’s deep surveillance and forensic capabilities helped restore order and accountability. Details were intentionally limited to avoid interfering with the ongoing legal investigation.
