stUSDe
stUSDe is a yield-bearing synthetic dollar fully backed by USDe. It represents the Senior Yield Tranche and offers superior risk-adjusted returns by providing uncapped upside exposure to sUSDe yield, while ensuring principal protection and a guaranteed minimum yield tied to the benchmark rate (Sky Savings Rate) for investors seeking predictable and low-risk yields in DeFi.
stUSDe always earns a share of the yield generated by the protocol on the pooled collateral by staking USDe. Its yield has a floor equivalent to the Sky Savings Rate (SSR) ensuring uncapped upside exposure to sUSDe APY with minimum guaranteed yield. In extreme scenarios (stJLP TVL ~ 0, sUSDe APY < SSR), stUSDe yield will be equivalent to the sUSDe yield.
stUSDe is ideal for users with a conservative risk profile, including institutions, DAOs, and TradFi retail savers.
