SKHX flash crash breaches Hyperliquid's backup liquidator, triggering forced liquidations of over $26 million.

Hyperinsight monitoring shows that after South Korea’s pre-market trading opened at 7 AM this morning, SKHX on Hyperliquid plunged rapidly from $1,128.2 to $927, with a maximum drop of 17.8% within one minute. As of press time, SKHX has rebounded to $1,097.9, up 18.4% from its low, with a 24-hour trading volume of $891 million. Market participants widely attribute the price anomaly to an oracle capturing extreme trade quotes during South Korea’s pre-market thin liquidity window. However, as of press time, the platform has not yet classified the event as a technical malfunction. More specifically, SKHX’s oracle synced the abnormally low price of South Korea’s NXT pre-market, which was then passed to the mark price, triggering a cascade of long position liquidations. Per trade.xyz’s rules, SKHX’s oracle price is calculated by dividing SK Hynix’s South Korean stock price by the USD/KRW exchange rate, and it accesses external executable quotes during South Korea’s pre-market session. During the liquidation wave, on-chain backup liquidation account 0x400…0001 took over 406 SKHX long positions at 7 AM, totaling around 27,100 contracts, at an average takeover price of roughly $969, with a nominal value of about $26.26 million and generating an realized loss of approximately $1.001 million. As SKHX’s price continued to drop, this backup account—originally tasked with absorbing user risk—was itself reverse-liquidated. The incident saw risk not stop after the position transfer, but instead spread further to the backup liquidation account. Compared to yesterday’s afternoon snapshot, SKHX’s open interest fell from 410,700 contracts to 353,600, a decrease of roughly 13.9%. Calculated at the mark price, the nominal position value dropped from around $508 million to $388 million, a decline of about 23.5%. Address: 0x40000000000000000000000000000000000000001
