sUSDat is the yield-bearing version of USDat, Saturn's stablecoin backed 100% by digital credit (STRC from MicroStrategy's Strategy). As digital credit dividends accrue, the sUSDat exchange rate against USDat increases.
This is a max-APY yield loop: sUSDat is supplied as collateral and AUSD is borrowed against it on Morpho, then recycled back into sUSDat to multiply the underlying Digital Credit yield. Because the two assets are price-correlated, the position targets amplified yield rather than directional price exposure.
Live APY, leverage multiplier and available liquidity are shown in the app.
