Ethena

USDe yield is generated by holding spot Ether and simultaneously shorting Ether perpetual swaps, capturing the funding rate paid by longs to shorts. That cash-and-carry return is combined with staking rewards from the spot Ether collateral. The blended yield is passed to holders through sUSDe, the staked token that automatically accrues protocol rewards.

USDe is backed by spot Ether and offsetting short perpetual-swap positions, creating a delta-neutral portfolio that aims to maintain a dollar-equivalent value. Unlike fiat-backed stablecoins, there is no bank account holding U.S. dollar reserves; instead, third-party custodians hold the spot Ether and exchanges hold the derivatives positions. Independent attestations of the backing assets are published weekly on Ethena’s website.

USDe and sUSDe have been integrated across Ethereum’s main lending and yield protocols, including Aave, Morpho, and Pendle. On Hyperliquid, USDe serves as a foundational dollar primitive for on-chain perpetual trading. Ethena’s March 2025 partnership with Binance further enabled USDe as reward-bearing collateral for futures and perpetuals across the exchange’s user base of over 280 million accounts.

Ethena does not fit either category. It is a protocol issuer that generates yield from a delta-neutral crypto derivative strategy and distributes it through a synthetic dollar token. It does not disclose any private wealth backing, family-office governance, or registered investment-advisor status, and its website positions it as an infrastructure provider for internet-native money.

Ethena provides a real-time dashboard showing the protocol’s backing ratio and publishes weekly proof-of-reserves reports verified by independent third-party attestors. Monthly custodian attestations confirm the value of the spot assets held at custodians. The protocol also states the share of time USDe has traded below its $0.997 reference peg since launch.

Ethena’s public website and product documentation do not name founders, executives, or a parent corporation. The protocol refers to Ethena Labs as the development entity but provides no entity-level disclosures, no office locations, and no team biographies. All public materials describe the product architecture rather than the operating company.

HyENA is a decentralized perpetuals exchange built on Hyperliquid’s HIP-3 standard that uses USDe as its margining and collateral asset. It extends USDe’s utility from passive yield-bearing collateral into active leveraged trading infrastructure. Ethena announced HyENA in early 2026 as part of a strategy to embed USDe deeper into derivatives trading rails.
