# jrUSDat

Junior USDat (jrUSDat) is a liquid, yield-bearing derivative of USDat that provides leveraged upside to sUSDat yield, while absorbing its volatility from STRC exposure and underwriting underlying\
strategy and collateral risks as first-loss capital. In return, it earns a risk premium from the senior tranche, resulting in potentially higher returns than sUSDat.

Junior USDat captures the residual returns after the senior tranche is paid and absorbs any\
shortfall to the guaranteed yield for srUSDat. As a result, it tends to outperform sUSDat\
when its NAV increases but may underperform when sUSDat incurs losses, reflecting its\
role as first-loss capital with a high-risk, high-return profile.
