On February 20, 2025, Justin Sun, the founder of TRON, provided insights into USDD, a stablecoin issued by TRON, through a tweet. He highlighted that the 20% annual yield offered by USDD is not exceptionally high when compared to other stablecoins in the market. For instance, USDS, another stablecoin, previously offered an annual yield of 11% as reported by CoinMarketCap on January 15, 2025. Justin Sun emphasized that the 20% yield of USDD is a competitive response to the market rather than an anomaly.
