Staked USDe (sUSDe) — Complete Guide

sUSDe is the yield-bearing staked version of USDe, created by depositing USDe into the Ethena staking contract. It is not a separate stablecoin but rather an interest-bearing receipt token that accrues the funding rate and staking yield generated by Ethena's delta-neutral strategy. sUSDe has become one of the most used yield-bearing stablecoins in DeFi, with over $2 billion in TVL and integrations across Aave, Morpho, Pendle, and Curve.

USDe holders deposit their tokens into the Ethena staking contract and receive sUSDe at the current exchange rate. The sUSDe/USDe exchange rate increases over time as Ethena's delta-neutral positions accumulate funding payments and ETH staking yield. Holders do not need to claim or compound — the yield accrues automatically via the rising exchange rate. sUSDe can be redeemed for USDe at any time, subject to a 7-day cooldown period designed to prevent rapid withdrawals during market stress. The yield comes from: (1) perpetual futures funding rates when longs pay shorts, and (2) stETH staking yield from spot collateral.
