Trade.xyz has officially begun reimbursing victims of the $60 million SK Hynix perpetual contract liquidation that occurred on Monday, July 27, 2026. According to AMBCrypto, the Hyperliquid HIP-3 deployer announced a reimbursement program on Wednesday, July 29, 2026, to rebuild trust and market integrity. The company has already paid out victims with claims of less than $10,000 based on $1,115 per SKHYNIX, while wallets claiming larger amounts will require enhanced due diligence for final payouts by August 15, 2026. For amounts exceeding 10,000 USDC, an initial 9,999 USDC has been credited to affected users, with the company conducting enhanced due diligence for larger claims.
One trader emerged as a significant winner from the SK Hynix perpetual contract crash, realizing $2.2 million in profit during the liquidation incident. According to Arkham, the trader, identified as Stately, gained approximately $2.2 million after part of his short position was automatically reduced during an auto-deleveraging event. The trader maintains an open short position worth $13.36 million, which now shows an additional $2.1 million in unrealized gains. This contrasts sharply with the $57.4 million in liquidated long positions across 960 accounts that were affected by the crash. As reported by AMBCrypto, the actual losses were estimated at $17.4 million in realized losses affecting over 900 user accounts.
The SK Hynix perpetual contract experienced a 17.9% flash crash on Monday, following an unusual pre-market trading session in Seoul. According to Trade.xyz, the mark price fell from approximately $1,127.90 to $917.25 at 23:01 UTC on July 27, representing a significant disruption to the perpetual futures market. The crash came from an executed trade on what Trade.xyz called the primary Korean pre-market venue, where a single order moved the price nearly one-fifth due to thin liquidity conditions. The underlying stock later closed the regular Seoul session at 1.55 million won, down 14.65%, though this closing move remained far above the isolated NXT print. As reported by AMBCrypto, the flash crash was triggered by an oracle pricing mishap and partly by ongoing volatility in the South Korean market, with SK Hynix trading at $1,087 after briefly slipping to $900 earlier in the week.
The unusual trading activity triggered significant liquidations across the SK Hynix perpetual contract. As reported by Trade.xyz, nearly $60 million worth of long positions were closed within two minutes, with on-chain analysis by Allium estimating $17.4 million in realised losses among more than 900 users. The contract's guardrail system, which provides a 10% instantaneous bound and one permitted reset, absorbed close to 11 percentage points of the corrupted price while allowing a 19% slide that cleared leveraged longs comfortably. The backstop then auto-deleveraged profitable shorts, booking roughly $10.8 million across 100 accounts. On-chain tracker Lookonchain estimated that more than $80 million in SKHX positions were liquidated, though Trade.xyz has not confirmed this figure or stated its expected reimbursement liability. The contract later recovered above $1,100, demonstrating the immediate impact of the South Korean trading session on the perpetual contract pricing.
The SK Hynix incident has highlighted the growing dominance of Trade.xyz within the Hyperliquid ecosystem. According to AMBCrypto, TradeXYZ controls over 95% of Hyperliquid's HIP-3 volume and Open Interest, with HIP-3 or perpetuals tied to commodities and stocks accounting for 65% of the overall DEX volume in 2026. Surprisingly, crypto perps, which Hyperliquid began with, now account for less than 1% of overall HIP-3 volume. Critics argue that TradeXYZ's excessive dominance poses a 'structural risk' to the broader ecosystem in case it's exploited or sanctioned. The massive demand for HIP-3 is dominated by a single deployer, with analysts noting that the current Hyperliquid design favors big HIP-3 deployers like TradeXYZ, as smaller players like Felix were forced to close shop. The project's HIP-4 (prediction markets and Options trading) went live on mainnet on Friday, though whether the Hyperliquid team will accept feedback to reduce TradeXYZ's dominance remains unclear.
