Stable Brings Institutional USDT Yield Onchain Through Morpho Vault Backed by Theo
Stable‘s announcement, shared with Bitcoin.com News, notes that USDT holds a near $190 billion in market cap and accounts for over 50% of the global stablecoin market. Despite that scale, users and businesses looking to put idle USDT to work have had limited access to competitive yield options natively on the chain. StableEarn is Stable’s attempt to close that gap.
The first vault runs on Morpho, an onchain lending protocol. Risk parameters are curated by Gauntlet, a risk management firm with more than $1 billion in assets under curation and one of the longer-standing curators on the Morpho protocol.
The yield is sourced through Theo, a real-world asset platform co-founded by former quantitative traders from Optiver and IMC. Theo’s products sit at the center of the vault’s strategy.
Three products from Theo back the vault: thBILL, which offers tokenized exposure to U.S. Treasury bills; thGOLD, a gold-denominated carry product; and thUSD, a delta-neutral yield product derived from gold derivatives. Each product is backed by physical or institutional-grade collateral and hedged on CME and NYMEX futures exchanges.
Theo works with Standard Chartered’s Libeara division and Wellington Management as part of its institutional partner network. The vault structure channels USDT deposits into these strategies, generating yield from real-world market activity rather than token incentives.
Brian Mehler, CEO of Stable, said USDT holders have lacked access to competitive yields despite the stablecoin’s dominant position. “StableEarn changes that by bringing together institutional-grade yield and the chain built around USDT,” Mehler said.
Iggy Ioppe, CIO of Theo, framed the product as a model for onchain dollar yield. “USDT-native, institutional-grade, with returns generated by real-world markets,” Ioppe said. “The future of crypto is real yield from real markets, delivered natively where capital already lives.”
StableEarn targets neobanks, fintechs, payment processors, and individual users who hold USDT and want yield without moving assets off the Stable network. Stable is built around USDT and partnered with Tether. The chain is designed for low-cost, high-speed stablecoin payments, with gas fees payable in USDT. StableEarn extends that infrastructure into yield generation.
Theo’s products are integrated across more than 15 decentralized finance ( DeFi) protocols. The firm uses a quantitative risk framework developed in-house by its founding team.
Both companies positioned the vault as an early step. More vaults and yield strategies on the Stable network have not been announced, but the infrastructure is in place for additional products.
