WisdomTree’s WTGXX holds nearly $860M in distributed asset value, mostly on Ethereum.

Pre-launch DeFi lending protocol Lotus has announced that WisdomTree’s Treasury Money Market Digital Fund (WTGXX) will serve as part of the reserve framework backing LotusUSD, its core vault token, according a press release shared with The Defiant. The DeFi protocol said the move marks one of the first instances of a money market fund being referenced within a DeFi lending protocol.
LotusUSD reserves are composed of USDC and tokenized short-duration U.S. Treasuries. According to the release, WTGXX integration is designed so that lenders earn a baseline yield even at zero utilization, sidestepping the structural problem in standard DeFi lending where returns dry up when borrowing demand is low.
WTGXX currently tokenizes over $857 million in U.S. Treasuries, primarily on Ethereum with a secondary allocation on Arbitrum, and carries a 7-day APY of 3.49%, per data from RWAxyz.
The integration is made possible in part by WisdomTree’s recently granted Securities and Exchange Commission exemptive relief permitting 24/7 instant settlement of WTGXX shares — a prerequisite for compatibility with around-the-clock DeFi infrastructure.
“We are seeing growing interest in connecting regulated financial assets, such as WTGXX, with blockchain-based infrastructure,” Maredith Hannon, head of BD for digital assets at WisdomTree said in the release. “This momentum reflects broader exploration of how tokenized traditional assets may be used within emerging digital ecosystems.”
Lotus also uses a tranched market structure, letting lenders select explicit risk profiles within a single connected liquidity pool rather than accepting uniform pool-wide exposure, per the protocol’s documentation.
The announcement comes days after the Kelp bridge exploit, which saw an attacker mint unbacked rsETH and use it as collateral on Aave to borrow nearly $200 million in real assets, and left Aave modeling between $124 million and $230 million in bad debt. Lotus founder and CEO David Reising drew a direct line between that event and the protocol’s design thesis, telling The Defiant:
“Yield in DeFi lending markets is too reliant on risky, volatile collateral. This was highlighted by this weekend’s KelpDAO exploit and the subsequent $15B Aave fallout — one of many events that have demonstrated the need for risk that’s predictable, bounded, and priced fairly.”
Reising argues the problem is structural, continuing in comments to The Defiant: “The desire to lend against subprime assets, like rsETH, is a market structure issue that can be eliminated by letting people sit at a variety of risk levels in asset markets containing high-quality collateral. Collateral risk isn’t the only option to generate high returns.”
On how Lotus’s design addresses it, Reising added:
“When lenders earn a reliable base rate on stable assets via productive debt, opaque collateral becomes less attractive by default, and platform-level tail risk shrinks before an exploit happens.”
Lotus lists pre-deposit vaults opening in May 2026, with general availability to follow. Early access requests are open on the protocol’s launch page.
Tokenized Treasuries have seen strong DeFi adoption, with protocols like Aave’s Horizon RWA Market now accepting them as collateral — a trend Lotus is extending further into lending market design.
