JELLY (JellyJelly / JELLYJELLY) is a Solana memecoin launched in January 2025 by Venmo co-founder Iqram Magdon-Ismail that became the center of a major market manipulation incident on Hyperliquid on March 26, 2025. A coordinated trader used a self-liquidation strategy — opening large opposing long and short positions — to force Hyperliquid's HLP liquidity vault to absorb a toxic short, causing up to $13.5 million in unrealized losses before validators emergency-delisted the token and force-settled all positions at a fixed price. The incident triggered widespread criticism of Hyperliquid's decentralization claims and raised systemic questions about perpetuals DEX risk management.

Ethena is a DeFi protocol founded in 2023 by Guy Young that issues USDe, a synthetic dollar stablecoin backed by delta-neutral perpetual futures hedges on centralized exchanges. The protocol reached $14 billion in supply at its 2025 peak before contracting sharply to approximately $5.9 billion following a flash crash in October 2025 and BaFin's enforcement action that forced Ethena GmbH to cease EU operations. Multiple concerns have been raised including: a German regulatory shutdown citing MiCA breaches and alleged unregistered securities offerings via sUSDe; insider airdrop farming allegations involving 180 million foundation-controlled ENA tokens; two separate security incidents (Discord hack July 2024 and domain registrar compromise September 2024); and structural risks tied to funding rate volatility, exchange counterparty exposure, and an undersized reserve fund relative to protocol TVL.
