USDe is a synthetic U.S. dollar launched in 2024 by Ethena. Unlike reserve-backed coins, it is not held one-for-one in a bank. Instead it maintains its peg using a delta-neutral strategy.
Ethena backs USDe with crypto collateral such as staked ETH and Bitcoin, then opens offsetting short positions on derivatives exchanges so the combined value stays close to a dollar regardless of price moves. Holders can stake USDe to receive sUSDe and earn yield.
How USDe holds its peg
USDe is a synthetic dollar. Its collateral is hedged with short perpetual-futures positions, so a fall in the value of the collateral is offset by a gain on the hedge. The yield on sUSDe comes largely from staking rewards and the funding rates paid on those derivative positions.
Understand the risks
USDe is structurally different from reserve-backed stablecoins and carries distinct risks: negative funding rates that can erode yield, exchange and custody counterparty risk where the hedges are held, and liquidity stress in volatile markets. It is best understood as a yield-bearing synthetic dollar, not a like-for-like substitute for USDC or USDT.
What USDe is used for
- A dollar-pegged asset that natively generates yield via sUSDe
- Collateral and liquidity across DeFi
- Diversification away from purely fiat-backed models
