FARTCOIN Price Pumped 27% Then Crashed in Hyperliquid Manipulation Attempt

A trader using four coordinated wallets built a 145.24 million FARTCOIN leveraged long position on Hyperliquid, triggering a forced liquidation that cost the attacker $3.02 million and pushed $1.5 million in losses onto the platform’s liquidity vault.

Key Takeaways:

• A trader using 4 wallets built a 145.24M FARTCOIN long on Hyperliquid, losing $3.02M on April 9, 2026.
• Hyperliquid’s HLP vault absorbed roughly $1.5M in realized losses as ADL mechanics were triggered by thin liquidity.
• Peckshield analysts suspect the same actor behind prior $XPL manipulation may strike similar low- liquidity perp markets next.

FARTCOIN Perp Exploit on Hyperliquid Drains $1.5M From Liquidity Vault in Hours

The position, flagged by onchain analysts like Lookonchain, and worth approximately $15 million notional at the time of entry, drove a temporary price move of roughly 19% to 27% in the Solana-based meme coin before reversing sharply. The reversal wiped out the entire long within about three hours on April 9, 2026.

Onchain security firm Peckshield also identified the event as a deliberate “suicide liquidation” exploit. The strategy involves building an oversized leveraged position in a thin market, forcing a self- liquidation, and activating Hyperliquid’s Auto-Deleveraging mechanism to transfer the toxic position to the platform’s liquidity pool.

Hyperliquid‘s HLP vault, the community-funded pool that absorbs bad debt during liquidations, took on the failed long position. The vault recorded approximately $1.5 million in realized losses within 24 hours and roughly $3 million in total book losses tied to the event.

Two short wallets identified by onchain addresses 0x06ce and 0x4196 captured gains through the ADL process. Those positions realized approximately $512,000 and $337,000, respectively, totaling around $849,000 in profit on the short side.

The long positions tied to addresses beginning 0x71c9 and 0x511c were liquidated in the $0.18 to $0.21 price range, where the market reversed after the initial pump collapsed.

Peckshield and other onchain analysts believe the trader likely held offsetting short positions or spot exposure on other exchanges, making the on-paper $3 million loss a net profitable trade when viewed across venues.

FARTCOIN trades on Hyperliquid’s perpetuals market as a high- leverage instrument. Low liquidity in meme coin perp markets creates conditions where concentrated positions can move prices and force platform-level mechanics into action.

The ADL system, designed as a risk management tool, becomes a liability when a trader engineers the conditions that trigger it. By building a position large enough to guarantee liquidation in a low- liquidity window, the attacker effectively redirected losses to the HLP vault and gains to strategically placed shorts.

Peckshield noted similarities between this event and a prior manipulation involving XPL on the same platform, suggesting a repeat actor or group using an established playbook against meme coin perp markets.

Hyperliquid has not issued a public statement on the incident as of the time of reporting. The platform saw billions in notional volume tied to the position, while the actual capital transfer ran into the millions.

The event reflects a known tension in decentralized derivatives platforms: open-access leverage in illiquid markets creates attack surfaces that traditional exchanges manage through tighter position limits and circuit breakers.

Traders on Hyperliquid and similar perp DEXs now face renewed questions about HLP vault exposure and whether current ADL thresholds adequately protect liquidity providers from coordinated manipulation.
