The protocol relies on crypto markets rather than bank reserves. That design shapes how USDe works and the risks it carries.
What is Ethena's role?
Ethena is a DeFi protocol that issues USDe and ENA. USDe's role is to act like a dollar in onchain markets, so users can hold stable value or move funds between DeFi apps. ENA is a separate token.
How does USDe work?
Ethena holds crypto collateral and shorts ETH perpetual futures. A perpetual future is a derivatives contract that tracks an asset's price without an expiry date. The short position can gain when ETH falls, which helps offset losses on the collateral and keeps USDe near its dollar peg. Staking USDe gives sUSDe, and its return comes from staking rewards and funding rates that can fall or turn negative.
Who launched Ethena and when?
Ethena Labs launched USDe on Ethereum mainnet in February 2024. The team later airdropped ENA in April 2024. ENA is a separate token from USDe.
What risks and legal limits exist?
USDe briefly fell below its dollar peg in April 2024 during severe market stress. sUSDe return is not guaranteed, because funding rates can fall or turn negative. USDe is not a bank deposit and is not FDIC insured.
Frequently asked questions

No. USDC and USDT mainly hold cash and similar reserves. USDe holds crypto collateral and shorts ETH perpetual futures, so it carries different risks.
