Single Trade Triggers 17.9% Flash Crash in Hyperliquid SK Hynix Market

The disruption highlights the vulnerabilities inherent in the HIP-3 framework, which empowers independent teams like Trade.xyz to deploy markets with custom oracle inputs. By tracking the U.S. dollar value of a single Korean share, the SKHX contract proved hypersensitive to localized liquidity gaps. As the one-share trade hit the exchange’s lower price limit, the contract price plummeted from roughly $1,128 to $927, triggering potential liquidations for leveraged traders.

Trade.xyz remains responsible for the market’s oracle selection and settlement logic under the protocol’s architecture. While no evidence suggests a compromise of Hyperliquid’s underlying smart contracts, the incident underscores the risks of linking thin pre-market sessions to automated on-chain derivatives. Trade.xyz is currently investigating the failure of its price-feed safeguards and has yet to release a final incident report. The market continued to operate following the flash crash, leaving participants to await clarity on whether existing filters will be adjusted to prevent similar oracle-driven volatility.
