The price of Hyperliquid’s perpetual contract for SK Hynix (xyz:SKHYNIX) dropped sharply on Tuesday, falling almost 18% after unfavorable pricing in Seoul. This resulted in the forced closure of $57.4 million worth of long positions held by approximately 960 traders.
Hyperliquid wasn’t involved in running that particular market; Trade.xyz was, using a system called HIP-3. This difference is important because it determines who had control over the market prices and who is responsible if something goes wrong.
What Caused the SK Hynix Perp Crash on Hyperliquid
The change was sparked by NXT, a new South Korean stock trading platform that began operating in March 2025. Unlike the main Korean stock market, which is open from 9 a.m. to 3:30 p.m., NXT trades from 8 a.m. to 8 p.m. local time.
Trading volume was low before the market officially opened. An unusually large pre-market order briefly valued one share of SK Hynix at 1,272,000 won, according to some high-speed traders. However, this price hasn’t been officially confirmed by either SK Hynix or the trading firm.
According to Yahoo Finance, SK Hynix stock closed yesterday at 1,785,000 won. Today’s price drop of 28.7% caused trading in Korea to be temporarily suspended.
The contract uses an external source to get price information during regular trading hours, as outlined in Trade.xyz documentation. It then converts Korean Won into US Dollars using the current exchange rate. Unfortunately, incorrect data was used as the basis for these calculations.
The situation already made a decline seem likely. SK Hynix was already experiencing a drop in value due to concerns about AI memory stocks, and a broader crash in the Korean stock market had caused the KOSPI index to fall by 8% earlier that day.

Why the Perp Fell 17.9% and Not 28.7%
The contract’s price decreased much less than the actual printed price, and this was intentional – not accidental. Trade.xyz limits how much the estimated price can change with its ‘discovery bounds’ feature.
According to the official specifications, xyz:SKHYNIX can experience a sudden drop of up to 10%, and is allowed one recovery period. These limitations create a lower limit of 19% below the starting point of the session. The recent 17.9% decrease stopped just above this lowest allowable level.
The safety net functioned as expected, preventing a much larger price drop. It reduced the impact of a problematic price movement by almost 11%, and also accommodated a 19% decrease without triggering liquidations for those who had bet on the price increasing.
According to on-chain data from MarketsAlpha, around 960 traders who bet against the market were forced to close their positions, resulting in approximately $17.3 million in losses. Following this, a safety mechanism automatically reduced the leverage of winning short sellers, generating about $10.8 million in profit across 100 accounts. Hyperliquid and Trade.xyz haven’t yet verified these numbers.
A specific setup detail increased potential risk. SK Hynix futures use a system where losses can be covered by funds allocated to other positions (cross margin). However, Samsung and Hyundai futures on the same platform keep their funding separate. This means that if one trade loses money with SK Hynix, it can impact your entire account, while isolated trades from Samsung or Hyundai won’t affect each other.
Why Hyperliquid Says the SK Hynix Perp is not its Market
A Hyperliquid team member, using the username iliensinc, responded to upset traders on the project’s Discord server. The discussion focused on fundamental issues with the system, rather than simply trying to defend it.
Hyperliquid is a blockchain open to everyone. Teams can build and run their own markets on it, using Hyperliquid as the underlying technology. Iliensinc, the anonymous co-founder and lead developer of Hyperliquid, stated that the XYZ team is looking into a recent issue and will provide an update when they have more information.
HIP-3 operators directly influence the price used for calculating mark prices, as well as the data from external sources. Hyperliquid only provides one part of the overall price calculation.
Let’s illustrate with an example. Imagine the average price from recent trades, the highest buy order, and the lowest sell order on the blockchain is currently $100. If someone then submits prices of $150 and $151, the new average price becomes $150. Essentially, the submitted prices override the existing ones.
Can Trade.xyz be Slashed, and Would Traders be Repaid?
Validators have the power to potentially reduce the amount of HYPE in circulation. Current rules state that those launching a new system must maintain a stake of 500,000 HYPE – roughly $27.4 million as of Tuesday. A vote by validators, weighted by their staked HYPE, can initiate a process to remove (or ‘burn’) these tokens.
There are two important considerations regarding this issue. First, simply identifying code as having ‘slashes’ doesn’t distinguish between intentional harm and simple mistakes. Second, it could even flag someone who accurately implemented a flawed design.
As an analyst, I’m seeing a particularly harsh outcome for traders involved. The penalty mechanism completely destroys the staked amount, offering no compensation to those impacted. Even if the full penalty were applied, the 960 accounts that were liquidated wouldn’t receive any funds back – it’s a total loss for them.
A price limit also helps prevent unwanted liquidations. Normally, validators automatically check collateral when the price changes by more than 50% from the beginning of the day, but the recent price shift on Tuesday wasn’t nearly that large.
Trade.xyz hasn’t explained what happened after the incident, nor offered any way to make things right. But there are three key dates to watch in the next month.
- SK Hynix reports earnings on July 29, which will push the same Korean feed through heavy volume.
- Deployers must hold the 500,000 HYPE stake for at least 183 days after launch.
- Stake stays slashable through a seven-day unstaking queue, so the window for validator action remains open.
Past actions set examples that can be applied in different ways. Just months ago, in March 2025, Hyperliquid faced criticism for acting like a central authority when it manually closed trades during the JELLY delisting. Now, they’re claiming they shouldn’t intervene in this situation. It’s worth noting that other independent teams have also previously shut down Hyperliquid markets and settled positions themselves.
Financial regulators are actively considering the issues surrounding platforms like Trade.xyz and Hyperliquid. Representatives from both companies recently met with officials at the Securities and Exchange Commission (SEC) to discuss crypto regulations. On Tuesday, the price of HYPE, Hyperliquid’s token, was around $54.82, which represents a decrease of approximately 9%.
The key issue isn’t overall market risk, but specifically whether allowing a 19% price swing is appropriate for this particular stock. Because trading volume is often low before the market officially opens, even one large order can significantly influence its starting price.
