Stable has launched StableEarn, an institutional USDT yield vault that lets USDT holders earn returns tied to US Treasuries and gold, extending the USDT-focused Layer 1 blockchain beyond payments into treasury management. Earlier information said the first pool is built on Morpho, managed by Gauntlet, and supported by Theo products including thBILL, thGOLD and thUSD. Stable says the offering is aimed at neobanks, fintech firms, payment processors and individual users seeking tools to manage idle balances and conduct onchain treasury activity.
