Key Takeaways:
TradeXYZ began repaying traders after a July 27 oracle glitch erased $60 million in SKHYNIX long positions on Hyperliquid, crediting claims under 10,000 USDC in full.
"Where it exceeds 10,000 USDC, an initial 9,999 USDC has been credited," TradeXYZ said in a statement on X, adding that amounts above that threshold require enhanced due diligence.
The flash crash at 23:01 UTC on July 27 was triggered by an anomalous SK Hynix pre-market print in South Korea that fed the perpetual's oracle, pushing the mark price down 18.7 percent from $1,127.90 to $917.25. Galaxy Research estimated roughly 960 accounts were liquidated, with long positions totaling $57 million to $80 million and realized losses of $17.4 million.
The repayment, calculated at a reference price of $1,115 per SKHYNIX, aims to restore trust in TradeXYZ and the broader Hyperliquid ecosystem, with larger claims due for final payout by Aug. 15.
TradeXYZ, the perpetual-futures arm of tokenization protocol Unit, was the first market to launch under Hyperliquid's HIP-3 builder-deployed perpetuals upgrade, which went live on mainnet in October 2025. Under the framework, any team staking 500,000 HYPE (about $27 million) can create its own perpetual markets.
The incident shows how a single stock-linked pricing error can ripple through on-chain derivatives. SKHYNIX traded at $1,087 as of writing after briefly slipping to $900 earlier in the week, while SK Hynix shares slid 14.65 percent to 1.55 million won as South Korean market volatility rose.
The payout comes as TradeXYZ's dominance of Hyperliquid's HIP-3 market draws scrutiny. HIP-3, which covers perpetuals tied to commodities and tokenized stocks, now accounts for 65 percent of Hyperliquid's overall DEX volume, with crypto perps making up less than 1 percent. TradeXYZ controls over 95 percent of HIP-3 volume and open interest, which analysts say poses a structural risk to the ecosystem if the deployer is exploited or sanctioned.
Smaller HIP-3 deployers such as Felix have already been forced to close, and critics have called for a more level playing field. Hyperliquid's HIP-4 upgrade, covering prediction markets and options trading, went live on mainnet on Friday, though whether the project will address the concentration concern remains unclear.
