USDE

USDe is a synthetic dollar issued by Ethena Labs that maintains its dollar peg through a delta-neutral strategy rather than traditional fiat reserve backing. The mechanism combines staked Ethereum (and other crypto collateral) with corresponding short perpetual futures positions, effectively neutralizing price exposure while generating yield from staking rewards and funding rate income. USDe is minted and redeemed through Ethena's protocol, with sUSDe (staked USDe) offering holders access to the protocol's generated yield. Unlike USDC or USDT, which rely on bank-held reserves and regulatory trust, USDe's stability depends on derivatives market liquidity, counterparty risk of the exchanges holding the hedge positions, and the persistence of positive funding rates. For traders, USDe perpetuals on HIP-3 offer a way to express views on the stability and adoption trajectory of the Ethena synthetic dollar model relative to its peg.
