Protocol Overview & Architecture
USDe-margined perpetuals that keep earning yield while positions stay open.
HyENA is a highly capital-efficient perpetual DEX built on Hyperliquid's HIP-3 framework by the Based team and powered by Ethena. Its core differentiator is the use of USDe (Ethena's synthetic dollar) as the sole collateral and quote asset.
All contracts on HyENA are linear derivatives where both margin and P&L are settled in USDe, giving traders direct USD-based exposure without any USDe/USD or USDe/USDT conversion friction. A unique advantage of this architecture is that users automatically earn native USDe yield and additional boosted rewards on their full margin balances while keeping positions open.
