--- title: Ethena ticker: ENA category: DeFi written_by: Unknown status: draft updated: 2026-10-31 --- # Ethena Ethena is the protocol behind USDe, a token designed to track the dollar using backing assets and hedging strategies. Ethena calls USDe a synthetic dollar and distinguishes it from fiat-backed stablecoins such as [USDC](usdc.md) and [Tether](tether.md). Its related tokens include sUSDe, which represents staked USDe, and ENA, its governance token.[^overview][^ena] | | | |---|---| | Type | Synthetic-dollar protocol | | Dollar token | USDe | | Staked dollar token | sUSDe | | Governance token | ENA | | Public USDe launch | February 2024, according to Ethena[^launch] | | Direct minting and redemption | Approved counterparties, subject to checks[^overview] | ## Backing and hedging Ethena's technical explanation describes matching volatile backing assets with short futures positions of approximately equal notional value. The intention is for gains on one side to offset losses on the other, limiting exposure to the asset's price direction. Stable backing assets do not require the same hedge. A dollar target is therefore supported by portfolio management and market infrastructure rather than solely by cash reserves.[^mechanism] As of 31 October 2026, Ethena's overview describes a wider range of revenue strategies, including crypto and non-crypto basis trades, lending, and tokenised real-world assets. These are the protocol's descriptions of its permitted approach; they should not be read as an independently verified statement of current portfolio weights.[^overview] ## Access and sUSDe The protocol distinguishes trading USDe in secondary markets from direct minting and redemption by approved counterparties. This distinction matters when comparing the market price available to a holder with the protocol's mint-and-redeem mechanism.[^overview] Users staking USDe receive sUSDe. Ethena describes rewards as discretionary: distributions increase the USDe value represented by each sUSDe token. Its documentation says periods of negative protocol revenue can result in no reward distribution, with the reserve fund intended to absorb losses. That intended buffer is not a guarantee of a fixed return or of loss-free backing.[^rewards] ## Governance and risks Ethena documents ENA as the token governing parameters including backing composition, new strategies, future revenue allocation, and the membership and remit of the Risk Committee. ENA and sUSDe therefore represent different roles within the system.[^ena] The protocol's risk documentation lists funding, liquidation, custody, exchange failure, and backing-asset risks. It specifically acknowledges that negative perpetual-futures funding can require Ethena to pay rather than receive funding. A hedge against price direction does not remove those operating costs or dependencies.[^risks][^funding] ## See also - [Stablecoin](stablecoin.md) - [MakerDAO and Sky](makerdao-sky.md) - [Curve](curve.md) - [Hyperliquid](hyperliquid.md) ## References [^overview]: Ethena. *Ethena overview*.
