What began as an aggressive trading move on a memecoin has turned into one of the most turbulent days for decentralized exchange Hyperliquid.
- Hyperliquid froze transactions after a POPCAT leverage trade caused massive losses.
- A $3M bet spread across 19 wallets triggered $25M in liquidations.
- The platform’s liquidity vault absorbed around $5M in debt.
- Analysts suspect deliberate market manipulation.
Withdrawals remain paused with no restart date announced.
The platform abruptly froze deposits and withdrawals on Wednesday after a single trader’s leveraged strategy backfired, leaving millions in bad debt and sparking renewed fears over the fragility of on-chain markets.
From Big Bet to Total Meltdown
According to blockchain data, the chain of events started when a trader withdrew about $3 million from OKX and distributed it across nearly twenty wallets. Those wallets collectively took massive long positions on POPCAT, amplifying exposure to around $25 million through 5x leverage.

Within minutes, the trade turned disastrous. As the memecoin’s price dropped, all positions were liquidated almost simultaneously, wiping out the trader’s collateral and transferring the remaining debt to Hyperliquid’s Hyperliquidity Provider (HLP). Roughly $5 million in losses landed on the HLP vault, forcing the exchange to take emergency measures.
Emergency Freeze and Market Fallout
Users soon noticed that transactions were halted. Conor Grogan, a former Coinbase executive, was among the first to confirm that Hyperliquid’s bridge had paused withdrawals for over 20 minutes. On-chain tracker ArbiScan also showed the bridge going inactive immediately after the liquidation storm — a move insiders believe was aimed at containing further contagion.
Analysts from Arkham Intelligence pointed out that the timing of the freeze coincided with the transfer of bad debt to the HLP, suggesting the platform’s automated risk system intervened to prevent broader losses.
A Price Wall That Crashed Down
Further investigation revealed that the trader had placed an enormous buy wall — worth around $20 million — near the $0.21 level to support POPCAT’s price. When those orders vanished, the token’s value plunged, triggering liquidation after liquidation.
On-chain researcher MLMabc described the maneuver as a deliberate attempt to manipulate the market, noting that the positions seemed designed to destabilize the exchange rather than profit from a genuine trade.
By the time the dust settled, Hyperliquid’s internal liquidity vault had absorbed millions in damage, prompting developers to manually close remaining positions to stop the bleeding.
Déjà Vu for the Decentralized Exchange
This isn’t Hyperliquid’s first run-in with targeted market manipulation. Earlier this year, a similar attack involving Solana’s memecoin JELLYJELLY saddled the platform’s community-owned HLP vault with $12 million in unrealized losses. That incident had already drawn scrutiny over how decentralized exchanges manage leveraged exposure and liquidation risk.
The latest POPCAT collapse has reopened those same concerns, with traders now questioning whether DEXs can remain resilient when a single actor can disrupt liquidity so dramatically.
No Timeline for Recovery
As of now, Hyperliquid has not indicated when deposits and withdrawals will resume. The pause, while temporary, has shaken market confidence and reignited debate over the safety mechanisms of decentralized financial systems.
Episodes like this illustrate a recurring problem for DeFi trading venues — the thin line between innovation and instability. When leverage meets illiquid markets, even a memecoin can bring an entire platform to a standstill.
