Stable launched StableEarn with partners Morpho, Gauntlet, and Theo, offering USDT holders institutional-grade yield backed by Treasuries and real-world assets.The product targets USDT’s structural yield gap, as Tether keeps all reserve interest as profit rather than passing any return to token holders.Tether’s USDT supply stands at approximately $150 billion across 15 blockchains, the world’s largest stablecoin by circulation, but one that pays zero native yield to holders.
