Hyperliquid’s JELLY crisis shows the thin line between decentralization and control

On March 26, 2025, the decentralized exchange Hyperliquid took a drastic and controversial step: it force-settled all open positions and delisted the JELLYJELLY (JELLY) perpetual futures contract. The move followed a chaotic price spike triggered by a massive leveraged short position, which exposed structural weaknesses in the exchange’s vault risk model and sent shockwaves through the community.

What began as a profitable play for a single trader quickly escalated into a potential $12 million meltdown, narrowly averted by validator intervention. But while the immediate threat was neutralized, the incident raised deeper questions—particularly about how decentralized a platform can be if it can act like a centralized exchange under pressure.

A $6M short, a vault collapse, and an emergency reset

The issue originated when a trader opened a $6 million short position on JELLY with 20x leverage. In a coordinated move, the same actor—or an associated one—began aggressively buying JELLY on the spot market, causing the price to skyrocket by nearly 500%. This created a reverse liquidation cascade where leveraged longs were squeezed upward, pushing the value of JELLY to levels that put Hyperliquid’s liquidator vault at risk.

At its peak, the vault faced $12 million in unrealized losses, and if JELLY’s market cap had hit $150 million, the entire vault could have been wiped out. To avoid this, the Hyperliquid validator committee stepped in and executed an emergency force-settlement of JELLY futures at $0.0095. This decision flipped the outcome from what could have been a disaster into a small net gain of $703,000.

Profit and manipulation in real-time

While the vault bled, another wallet—0x20e8—entered a long position worth $8.2 million during the price rally. This wallet exited the trade within minutes, securing an $8 million profit, raising serious concerns about insider coordination or front-running.

Meanwhile, the wallet responsible for the original short, 0xde95, was traced back through on-chain analytics. Not only had it initiated the short, but it also manipulated the spot price to trigger the liquidation mechanics. Further investigation revealed that this wallet and four others connected to it had accumulated nearly 10% of the total JELLY token supply between March 22 and the day of the exploit.

This wasn’t the first time such a pattern was observed. A similar manipulation took place with the BERA token earlier in February. The reappearance of the same exploit technique suggests that malicious actors may be targeting illiquid futures markets on decentralized platforms that lack the liquidity depth and governance responsiveness to defend against such attacks.

Organic growth or synthetic chaos?

Despite the enormous trading volume—JELLY saw a 1,852% surge in daily volume, reaching $170 million—the metrics revealed more manipulation than real demand. Transaction counts jumped by 997%, and the number of active traders increased by 961%. Liquidity, however, remained mostly unchanged at $2.99 million.

Sell volume slightly outpaced buys—$85 million to $84 million—suggesting the price was being pumped only to be dumped. On-chain behavioral analysis pointed clearly to deliberate orchestration rather than organic interest. The speed and intensity of the activity, all concentrated within a single 24-hour window, made it nearly impossible to ignore the signs of foul play.

A DEX acting like a CEX?

The most controversial part of the JELLY saga was not the manipulation itself, but how Hyperliquid responded. The validator vote to force-settle the futures contract, while arguably necessary to prevent systemic failure, sparked backlash across the DeFi community.

Gracy Chen, CEO of centralized exchange Bitget, accused Hyperliquid of operating like a centralized exchange while hiding behind a decentralized façade. She compared the move to decisions made by failed platforms like FTX, where centralized entities unilaterally intervened in markets.

Her strongest critique? That force-settling positions at a price favorable to the platform—and effectively locking in losses for some traders—undermined the very principles on which DeFi is built: transparency, immutability, and non-custodial control.

Centralization fears deepen

Arthur Hayes also chimed in, pointing out the contradiction between Hyperliquid’s brand and its actions. Critics argued that if a DEX can suddenly intervene in the market to protect itself, it ceases to be trustless.

Additional on-chain data revealed that some attacker wallets had links to centralized exchanges like OKX, Binance, and MEXC. Suspicion deepened when these same exchanges listed JELLY shortly after the Hyperliquid delisting. Wallet 0xde95 withdrew $6.26 million before restrictions were imposed, leaving only $900,000 locked—another sign that the attacker had prepared exit routes in advance.

In parallel, Hyperliquid’s native governance token, HYPE, dropped 22% following the vote, signaling a crisis of confidence among its user base.

Is this DeFi or centralized rescue?

Ultimately, Hyperliquid avoided disaster—but only by acting in a way that contradicts the very ethos of decentralization. That irony is what now haunts the platform.

In theory, decentralized exchanges are meant to remove human bias and top-down control. In practice, the JELLY episode revealed that when core infrastructure is at risk, even DEXs will abandon ideology for survival.

So here lies the deeper dilemma: Should a decentralized exchange have the authority to force-settle markets and delist tokens if it means saving the protocol? Or does doing so make it indistinguishable from the very centralized platforms it aims to replace?

This is more than a governance question—it’s a philosophical reckoning for DeFi. If protocols want to retain trust, they’ll need to choose: either build robust mechanisms to withstand such attacks or admit that some level of centralization is necessary.

What happened with Hyperliquid and JELLY wasn’t just about one exploit—it was a moment of truth for the entire decentralized finance ecosystem.
