Lotus, a pre-launch DeFi lending protocol, has integrated WisdomTree's Treasury Money Market Digital Fund (WTGXX) into its reserve framework for LotusUSD, its core vault token. This marks one of the first instances of a money market fund being used within a DeFi lending protocol. The integration aims to provide lenders with a baseline yield even at zero utilization, addressing a common issue in DeFi lending where returns diminish with low borrowing demand. WTGXX, which tokenizes over $857 million in U.S. Treasuries, offers a 7-day APY of 3.49% and is primarily based on Ethereum. The integration is facilitated by WisdomTree's SEC exemptive relief, allowing 24/7 instant settlement of WTGXX shares, aligning with DeFi's continuous operation. Lotus's design allows lenders to choose risk profiles within a single liquidity pool, enhancing risk management. The protocol's launch follows a significant exploit in the DeFi space, highlighting the need for stable, predictable yields. Lotus plans to open pre-deposit vaults in May 2026, with general availability to follow.
