- StableEarn brings USDT yield tools to Stable’s Layer-1 network using Morpho framework.
- Stable will route USDT deposits into Theo’s RWA products, including thUSD and thBILL.
- Gauntlet will curate the vault as Stable expands beyond stablecoin payment services.
Stable has launched StableEarn, a treasury product that brings USDT yield tools to its Layer-1 network. The product uses Morpho’s framework. It also combines Gauntlet’s curation and Theo’s RWA portfolio to support on-chain treasury activity for USDT holders inside Stable.
The first StableEarn vault will route USDT deposits into strategies built with Theo’s products. These include thUSD, thBILL, and thGOLD. Stable said the products are supported by real-world assets and regulated RWA structures.
The company said StableEarn expands its network beyond payments. Stable describes itself as a blockchain platform built for stablecoin transactions, with a focus on USDT. The new product adds yield-focused treasury tools inside the same ecosystem.
StableEarn Links USDT With Institutional Yield
Stable CEO Brian Mehler said USDT moves more value than any other stablecoin. He said users have faced challenges when trying to earn competitive yield on USDT. He added that StableEarn connects institutional-grade yield with a chain built around USDT.
Theo CIO Iggy Ioppe also commented on the launch. StableEarn demonstrates how an on-chain dollar yield can be designed in relation to USDT, he said. The product also introduces real-world market returns to where crypto capital is already present, he added.
The vault uses the Morpho protocol framework. Gauntlet is curating the first vault. Theo is delivering the portfolio of RWA-linked solutions to support the yield strategies. This configuration sets up the vault’s basic functions.
The launch is in line with Stable’s efforts to create more USDT-related functions. Its network is already around stablecoin payments. StableEarn now provides users with an additional use case for assets on-chain.

Gauntlet has worked on similar on-chain vault products before. The DeFi risk management platform last year introduced a USDC Prime Vault on Optimism’s OP Mainnet. That product was powered by Morpho Labs.
StableEarn Expands Stablecoin Yield
The USDC Prime Vault was built for individual users, traditional financial institutions, and crypto-native developers. It was a merger of Gauntlet’s risk modeling system and Morpho’s lending platform. The goal was to generate yield while maintaining a manageable risk exposure.
Optimism stated that the launch was in line with its strategy for blockchain financial products. The project also featured Utila.io for enterprise-level wallet security on OP Mainnet. The previous release demonstrated how vault products can be implemented on multiple blockchain networks.
StableEarn is also indicative of the broader trend of yield-bearing stablecoin products. In 2026, a number of crypto projects have launched products related to tokenized treasuries, money market funds, and structured RWA strategies. These products aim to link stablecoins to the market’s traditional returns.
These products also have risks. Vaults backed by RWA could experience counterparty risks, regulatory uncertainty, and the classic market volatility. StableEarn’s performance will depend on Theo’s strategies, Morpho’s framework, and Gauntlet’s risk controls. Users are advised to evaluate those risks prior to use of the vault.
