Wall Street Giants Go On-Chain: BlackRock BUIDL Launches on Uniswap and JPMorgan MONY DeFi Strategy Analysis

In the first quarter of 2026, the tokenization of real-world assets (RWA) has seen two landmark events. In February, asset management giant BlackRock’s USD institutional digital liquidity fund (BUIDL) officially integrated with the decentralized exchange Uniswap, allowing qualified investors to trade 24/7 via UniswapX technology. Earlier, in December 2025, JPMorgan, the largest bank in the U.S., launched its tokenized money market fund “My On Chain Net Yield Fund” (MONY) on the Ethereum mainnet, injecting $100 million of its own funds as seed capital.

These events are not isolated cases but represent a collective vote by traditional finance (TradFi) giants at this juncture in 2026 on “on-chain financial infrastructure.” This article will start from the events themselves, outlining the timeline, dissecting the structural changes behind the data, examining mainstream market opinions and potential risks, and ultimately exploring various scenarios for how this trend might evolve.

Event Overview: Two Landmark On-Chain Actions

On February 11, 2026, Uniswap Labs and tokenization platform Securitize announced a strategic partnership to integrate BlackRock’s BUIDL fund shares into the UniswapX trading framework. This integration allows pre-approved, whitelisted investors—screened by Securitize—to use the RFQ (Request for Quote) mechanism on UniswapX to perform two-way atomic swaps of BUIDL with market makers (such as Wintermute, Flowdesk, etc.) also on the whitelist. As part of the collaboration, BlackRock also made a strategic investment in the Uniswap ecosystem.

Meanwhile, JPMorgan’s MONY fund has been operating on Ethereum for several months. It was issued via JPMorgan’s Kinexys Digital Assets platform, with investors able to subscribe and redeem using cash or stablecoins like USDC through Morgan Money channels. MONY invests in U.S. Treasuries and repurchase agreements collateralized by Treasuries, with daily dividends reinvested, and its shares are issued directly as tokens to investors’ Ethereum addresses.

From Proof of Concept to Scale Deployment

Looking at the timeline, 2025 to 2026 marks a critical window for institutional RWA from “pilot” to “production.”

• 2024: BlackRock and Securitize launched BUIDL, quickly becoming the largest tokenized money market fund. At this stage, the market mainly mapped traditional fund products onto the blockchain, with circulation still limited within the issuer’s ecosystem.
• 2025: Regulatory frameworks gradually clarified. The passage of the U.S. GENIUS Act established licensing for stablecoin payments and explicitly prohibited paying interest to stablecoin holders. This regulation inadvertently created a significant comparative advantage for tokenized money market funds—they can be classified as securities and pass on yields from underlying assets to holders. In July, JPMorgan officially launched the MONY fund; in October, its Kinexys platform completed the first on-chain fund transaction; in December, MONY went live on Ethereum mainnet.
• February 2026: BlackRock’s BUIDL integrated with Uniswap, marking the beginning of tokenized assets that were once confined to permissioned chains or whitelisted systems actively engaging with the open DeFi liquidity layer.

Data Analysis: Hierarchies and Growth in the RWA Market

To understand the impact of these events, it’s essential to grasp the current structure of the RWA market. By the end of 2025, the global RWA market (public issuance) reached $18.87 billion, a 239.8% increase from the start of the year. The market has formed a stable three-layer pyramid:

BlackRock’s BUIDL is currently the leader in tokenized U.S. Treasuries, managing over $1.7 billion. JPMorgan’s MONY started with $100 million of its own funds, representing a strategic positioning by a banking giant in this space. While both products target low-risk assets like U.S. Treasuries, their strategic paths differ significantly.

Market Sentiment and Divergent Narratives

Market interpretations of BlackRock and JPMorgan’s actions vary.

BlackRock paving the way for institutional entry into DeFi

Hayden Adams, founder of Uniswap, views the partnership positively: it can “create efficient markets, better liquidity, and faster settlement.” The general sentiment sees BUIDL’s landing on Uniswap as a milestone—BlackRock’s first formal entry into DeFi. Although current trading is limited to whitelisted users, it demonstrates the technical and regulatory feasibility of trading regulated assets on a public DEX.

JPMorgan defensively reshaping “on-chain cash”

Another perspective sees JPMorgan’s MONY as a defensive move. Faced with stablecoins eroding traditional deposits and cash management, banks need to offer a regulated, interest-bearing, 24/7 settlement-capable on-chain alternative. MONY aims to bring large institutional capital into a structure under their control and regulatory oversight, directly competing with non-bank stablecoins relying on issuer balance sheet arbitrage.

Regulatory arbitrage as a core driver

Several analysts point out that the GENIUS Act’s restrictions on stablecoin yields are a key catalyst for the explosion of tokenized money market funds. Idle stablecoins held by institutions face opportunity costs of zero yield, while securities-like tokens such as BUIDL or MONY can legally pass on Treasury yields to holders. This makes them inherently attractive to institutional finance managers seeking capital efficiency.

Reality Check: Open vs. Closed Systems

Under the grand narrative of “Wall Street on Chain,” it’s necessary to examine the real operational details.

Fact: BUIDL can indeed be traded on Uniswap, and MONY is deployed on Ethereum mainnet. This aligns with the “openness” narrative.

Fact: Both are issued as private securities under SEC Rule 506©, only available to accredited investors. All transactions occur between whitelisted addresses that have passed KYC/AML checks. BUIDL’s trading counterparties on Uniswap are limited to whitelisted market makers, not all liquidity providers.

Viewpoint: This exemplifies a “permissioned DeFi” model. Ethereum’s openness provides programmability and 24/7 settlement, but asset transfers and ownership are strictly governed by compliance rules embedded in smart contracts.

Speculation: This “open underlying + permissioned application layer” model could become the standard for institutional on-chain finance—meeting regulatory control over securities issuance and transfer while leveraging blockchain’s efficiency in clearing, settlement, and composability.

Industry Impact: Multi-Dimensional Reshaping

Impact on stablecoin landscape

Tokenized money market funds are reshaping the functions of “on-chain USD.” Stablecoins may be further pushed into retail payments and low-value transfers, while large-scale institutional settlement, collateral management, and interest-bearing cash management could be increasingly dominated by BUIDL, MONY, and similar yield-bearing tokens. As Zodia Custody notes, DeFi is becoming an institutional “yield pipeline.”

Upgrading DeFi infrastructure

BlackRock’s entry compels DeFi protocols to upgrade infrastructure to meet institutional needs. UniswapX’s RFQ model is designed for large, low-slippage, private trades—perfect for institutions trading large fund shares on-chain. Future protocols may differentiate “institutional pools” from “retail pools” to meet varying compliance requirements.

Capturing value as Ethereum becomes a settlement layer

JPMorgan’s choice of Ethereum over private chains signals a clear message: liquidity is where the infrastructure is. Ethereum hosts about two-thirds of RWA assets and boasts the most mature stablecoin ecosystem and developer tools. For institutions needing integration with existing on-chain systems (like stablecoin settlement, custody reporting, compliance tools), Ethereum is an unavoidable hub.

Scenario Evolution: 1-2 Year Outlook

Based on the above, several future scenarios can be envisioned within 1-2 years:

Scenario 1: Gradual Integration

• Path: BUIDL and MONY demonstrate stable, compliant operations. More asset managers and banks follow suit, issuing their own tokenized funds on Ethereum or other public chains. Secondary trading remains mainly among whitelisted market makers and qualified investors, with liquidity gradually increasing.
• Milestone: Similar to BUIDL, assets start being accepted as collateral in major DeFi lending protocols (e.g., Aave), enabling initial DeFi composability.
• Impact: The public RWA market grows steadily, reaching $50-60 billion by late 2026.

Scenario 2: Regulatory Relaxation and Explosive Growth

• Path: U.S. regulators (SEC, Treasury) relax transfer restrictions on tokenized funds based on recommendations from bodies like TBAC. Tokenized fund shares can be transferred peer-to-peer among qualified investors without intermediaries.
• Milestone: Tokenized fund shares begin to exhibit “monetary” properties, used directly for payments or settlement in certain contexts.
• Impact: Market experiences exponential growth; McKinsey’s $2 trillion (by 2030) target could be reached earlier.

Scenario 3: Competitive Fragmentation and Liquidity Silos

• Path: Major banks prefer issuing and trading tokenized assets within their closed ecosystems to compete for clients. Although based on public chains, assets are isolated by different issuers’ compliant contracts, hindering liquidity aggregation.
• Milestone: BUIDL mainly circulates within Securitize’s ecosystem; MONY within Kinexys. Cross-ecosystem transfers require complex, costly redemption and re-issuance.
• Impact: “On-chain” becomes merely a bookkeeping layer; true “interoperability” and “liquidity sharing” are limited, turning RWA into isolated islands on the blockchain.

Conclusion

BlackRock’s BUIDL on Uniswap and JPMorgan’s MONY on Ethereum are not isolated hot topics but two different strategic responses by Wall Street giants at the regulatory and market crossroads of 2026. They jointly declare that the process of “bringing traditional finance on-chain” has moved from proof of concept to infrastructure deployment. For participants, the current benefits may not be immediate profits but witnessing the construction of a new, institution- and compliance-driven on-chain financial world, built step by step. When Wall Street truly goes on-chain, it signifies not just disruption but a profound reorganization around efficiency, compliance, and liquidity.
