Strata Senior USDat
Senior USDat (srUSDat) is a liquid, yield-bearing derivative of USDat that provides low-risk exposure to Saturn’s Bitcoin credit yield via STRC. It offers a fixed yield (65% of the STRC Dividend Rate) with no volatility and yield-bearing dollar like characteristics. Any shortfall to this guaranteed yield, along with underlying volatility and strategy risks, is absorbed by the Junior tranche, which provides explicit coverage to srUSDat holders.
srUSDat always earns a share of the yield generated by the protocol on the pooled USDat collateral by staking USDat. It offers a guaranteed fixed yield on USDat linked to the benchmark rate with no volatility and first-loss protection provided by the junior tranche against any underlying strategy and collateral risks. In extreme scenarios where the junior tranche is fully depleted, srUSDat would directly receive the sUSDat performance.
