iUSD is Cardano’s first fault-tolerant and fully collateralized native stablecoin released in November of 2022 as part of Indigo Protocol v1. iUSD is pegged to the median value of USDC, TUSD, and USDT; this design allows iUSD to maintain its peg even if one of the three stablecoins (USDC, TUSD, and USDT) depegs.
