Saturn
AuditedSaturn is a dual-token RWA stablecoin protocol on Ethereum, issuing USDat (a permissioned synthetic dollar backed by M0 tokenized T-bills) and sUSDat (an ERC-4626 yield vault earning ~11% APY via STRC preferred equity dividends), with a dynamic LTV reserve model that automatically shifts collateral allocation from STRC toward T-bills as Bitcoin/credit risk rises.

Score history
This rating is re-checked every month. A point is recorded for every check, so a flat line means we looked and nothing moved. Hover anywhere on the chart to see what moved that month, and by how much.
The Problem
T-bill yield stablecoins (~4-5% APY) do not capture the higher returns available from digital-asset-adjacent preferred equity (STRC: ~11.5%). Existing preferred equity exposure in DeFi lacks risk management and stable-dollar utility.
The Solution
Saturn routes USDat stakers into STRC preferred equity exposure via a dynamic LTV-managed reserve, capturing ~11.5% annual dividend yield in sUSDat while maintaining a T-bill backstop for stability. Monthly dividends vest linearly on-chain, eliminating lumpy cash flows.
Why it Matters
Dynamic LTV-triggered reserve reallocation automatically deleverages from STRC to T-bills as Bitcoin/STRC collateral risk rises — a risk-managed preferred-equity yield mechanism not available in existing T-bill stablecoin designs. Built on top of regulated M0 infrastructure with institutional custody.
