Trade.xyz will reimburse traders liquidated after its SK Hynix perp crashed 19% in minutes on July 27, blaming a single trade on a thin Korean pre-market venue.
Crypto Derivatives News
A single trade on a thinly traded Korean pre-market venue sent the mark price of a crypto perpetuals contract down nearly 19% in minutes on July 27. The contract, tied to South Korean chipmaker SK Hynix, is operated by Trade(dot)xyz on Hyperliquid. About $60 million in trader positions were liquidated as a result.
Trade(dot)xyz announced on July 29 that it will reimburse traders whose positions were wiped out by the move. The company said the reimbursement is a one-time discretionary decision and not a standing policy. Eligibility rules had not been fully disclosed as of July 29, though Trade(dot)xyz said distributions would go out within days.
How a Single Order Moved the Market
The mark price of the SK Hynix contract fell from $1,127.90 to $917.25 at 11:01 pm UTC on July 27. The move originated from an executed trade on an external market, not on Trade(dot)xyz's own order book. Multiple independent data providers picked up that price print and passed it through to the platform's oracle, the system that pulls real-world price data into a blockchain-based contract.
Trade(dot)xyz said its oracle converts SK Hynix's Korean won share price into US dollars using the prevailing exchange rate. The oracle was tracking the external venue the platform uses as its primary South Korean pre-market source. On a market thin enough for one order to move prices by nearly a fifth, the oracle had no mechanism to filter out the impact of that trade.
The platform said the oracle "worked as intended according to its specification." It acknowledged that traders were frustrated by the outcome. Trade(dot)xyz did not identify how many traders would qualify for reimbursement or state the total payout figure.

A Big Market, a Bigger Question About Pricing
The SK Hynix contract sits among Hyperliquid's more active markets. As of July 29, it had recorded over $1.5 billion in 24-hour volume and held close to $600 million in open interest. Trade(dot)xyz operates on Hyperliquid under its HIP-3 framework, which lets builders launch perpetual contracts that reference external price feeds. The platform accounted for more than $22 billion of the first $25 billion in cumulative HIP-3 volume. It also launched a licensed S&P 500 perpetual contract using S&P Dow Jones Indices data.
Going forward, Trade(dot)xyz said it is weighing how much authority to give external price feeds compared to prices formed on its own order book. It noted that its internal book now carries meaningful depth and market signal. The platform said it will review how prices are formed during extreme market events before making a final decision.
The SK Hynix price crash happened hours before Korean equity markets began a two-day decline. SK Hynix shares fell roughly 17% on July 29. That came after the company reported a 557% jump in quarterly profit, a figure that still came in below analyst estimates.
