HyENA Shuts Down Amid Shift in Hyperliquid's Stablecoin Strategy

The perpetuals exchange HyENA, built on Hyperliquid's HIP-3 framework and backed by Ethena, is shutting down after processing $4 billion in trading volume and serving over 12,000 traders. The platform will delist one market per hour over three days, starting August 31, 2026.

HyENA's model relied on USDe having room to grow as margin, but Hyperliquid's stablecoin setup moved closer to USDC in May 2026, making it harder for USDe-based margin to expand. This change in strategy by Hyperliquid weakened the case for HyENA, a product built around a rival margin asset.

Hyena depositors can redeem principal and accumulated rewards through Upshift at a 1:1 ratio with no withdrawal fee from HyENA and a one-day processing window. The shutdown is an example of the risk every protocol takes when it builds on someone else's rails, where the host platform can control the order book, margin engine, and favored stablecoin.
