Blockchain security firm PeckShield reported Friday that a wallet suffered a devastating loss of roughly $21 million worth of crypto assets on Hyperliquid, a decentralized trading platform. According to PeckShield, the theft stemmed from a private key compromise, allowing an attacker to drain the victim’s funds in a single swift move. The hack was isolated and was targeted towards the victim's wallet, not HyperLiquid itself. The stolen assets PeckShield claims included approximately 17.75 million DAI and 3.11 million MSYRUPUSDP, both of which the hacker has since bridged to Ethereum. #PeckShieldAlert A victim 0x0cdC...E955 lost ~$21M worth of cryptos on #Hyperliquid due to a private key leak.

This incident highlights the persistent risk of private key exposure in decentralized systems — even as smart contract security improves, user-side vulnerabilities continue to be a major attack vector. T he Hyperliquid case serves as yet another reminder that operational security and hardware wallet protection are critical to safeguarding digital assets in the self-custody era.
