Decentralized perpetual contract exchange HyENA has officially launched, currently available only to invited users. The platform is built on Hyperliquid's HIP-3 standard and uses USDe as the margin asset, developed by the Based team. Initial trading pairs include HYPE-USDe, BTC-USDe, ETH-USDe, and SOL-USDe. HyENA has also introduced the liquidity vault HLPe, allowing users to share in trading fees and margin profits, and participate in a points reward program. The platform has confirmed that it will not issue a separate HyENA token.
