Ethena

Ethena is a DeFi protocol that created USDe, a synthetic dollar that generates yield through a delta-neutral basis trading strategy. Founded by Guy Young and launched in early 2024, Ethena quickly became the fastest-growing stablecoin project in crypto history, reaching over $3 billion in TVL within months of launch. Unlike traditional stablecoins backed by fiat reserves or crypto overcollateralization, USDe maintains its dollar peg through a sophisticated hedging mechanism that simultaneously holds staked ETH (earning staking yield) and opens corresponding short perpetual futures positions (earning funding rates).

The protocol's yield-generating mechanism exploits a persistent market dynamic: in bull markets, demand for leveraged long positions causes perpetual futures funding rates to go positive, meaning shorts get paid. By combining staking yield with funding rate income, Ethena has consistently offered double-digit APYs on its sUSDe (staked USDe) product — far exceeding what traditional stablecoins or Treasury-backed products can offer. This high yield attracted massive capital inflows and made Ethena one of the most discussed protocols of the 2024-2025 cycle.

However, Ethena's model carries unique risks. During prolonged bear markets, funding rates can turn negative, meaning Ethena would need to pay to maintain its hedge rather than earning income. The protocol maintains an insurance fund to cover such periods, but extended negative funding could theoretically drain reserves. Despite these risks, Ethena has expanded to integrate with major DeFi protocols, and USDe has become widely accepted as collateral across lending platforms. By 2026, Ethena has grown into one of the top stablecoin issuers and continues to refine its risk management framework.
