JPMorgan and BlackRock expand their tokenized money market funds on Ethereum
JPMorgan Chase and BlackRock are both expanding their tokenized money market fund strategies on Ethereum, reinforcing the blockchain’s growing role as institutional infrastructure for traditional financial products.
JPMorgan, the largest U.S. bank with more than $4 trillion in assets, disclosed in a recent SEC filing plans tied to its “JPMorgan OnChain Liquidity Token Money Market Fund”. The filing outlines a blockchain-enabled structure for money market fund shares, allowing institutional investors to access tokenized exposure to short-term liquidity products backed by traditional assets such as Treasury securities, commercial paper, and repurchase agreements.
JPMorgan’s proposed tokenized money market fund, JLTXX, would invest exclusively in short-term U.S. government-backed instruments, including Treasury bills, notes, bonds, and overnight repurchase agreements collateralized by either U.S. Treasuries or cash. According to the filing, the fund is structured to maintain a stable $1 net asset value and will only hold U.S. dollar-denominated securities, positioning it as a low-risk institutional liquidity product. The blockchain infrastructure supporting the fund will be developed and operated by Kinexys Digital Assets, JPMorgan’s dedicated blockchain division, which will enable investors to submit and process fund share transactions through onchain systems.
Separately, BlackRock — the world’s largest asset manager with roughly $13 trillion under management — is preparing two additional tokenized money market products on Ethereum. The first would add an onchain share class to its existing BlackRock Select Treasury Based Liquidity Fund (BSTBL), a roughly $6.1 billion Treasury-focused money market fund that primarily invests in cash, short-term U.S. Treasury securities, and other debt instruments with maturities under 93 days. Under the filing, ownership records for the new share class would be issued on Ethereum using ERC-20 token standards.
The second filing covers a new product called the “BlackRock Daily Reinvestment Stablecoin Reserve Vehicle”, a tokenized liquidity vehicle designed for stablecoin-related reserve management and blockchain-native cash operations. According to the filings, the fund would invest in cash, short-term Treasuries, and overnight Treasury-backed repurchase agreements while issuing blockchain-based “OnChain Shares” through a permissioned framework connected to public blockchains. The structure also includes a reported $3 million minimum investment threshold, signaling an institutional-focused product rather than a retail offering.
The announcements add to a rapidly expanding institutional push into tokenized real-world assets (RWAs), particularly Treasury-backed products. Rather than changing the underlying investments themselves, tokenization digitizes ownership and transfer mechanisms by recording fund shares on blockchain networks. Supporters argue the structure can improve settlement speed, operational efficiency, and interoperability between traditional finance and digital asset markets.
Both firms are building on earlier blockchain initiatives rather than entering the space for the first time. BlackRock already operates BUIDL, its tokenized U.S. Treasury fund launched on Ethereum in March 2024, which became one of the fastest-growing tokenized finance products in the market. The fund surpassed $375 million in assets within six weeks of launch, crossed the $1 billion mark in March 2025, and at one point approached nearly $3 billion in assets as institutional demand for tokenized Treasury exposure accelerated. Industry data cited by Cointelegraph showed BUIDL accounted for roughly 41% of the entire tokenized Treasury market in 2025.
Meanwhile, JPMorgan has spent years developing blockchain-based settlement and tokenization infrastructure through its Onyx — now Kinexys — platform. The bank has processed hundreds of billions of dollars in tokenized transactions across payments, collateral transfers, and intraday liquidity operations, positioning itself as one of the most active traditional financial institutions building blockchain-based market infrastructure. The latest Ethereum-related filing expands that strategy into tokenized money market fund products aimed at institutional liquidity management.
Ethereum remains the primary network for many institutional tokenization projects due to its scale, liquidity, and established smart contract infrastructure. The latest expansions from JPMorgan and BlackRock further strengthen Ethereum’s position as the leading blockchain for regulated financial products and institutional-grade tokenized assets.
The developments also reflect a broader shift across traditional finance, where major banks and asset managers are increasingly treating blockchain technology as part of long-term market infrastructure rather than a standalone crypto experiment.
Dubai opens government payments to crypto under cashless push
Dubai is moving deeper into digital finance after the Government of Dubai announced plans to allow cryptocurrency payments for government service fees through a new partnership with Crypto.com. The initiative, unveiled by Dubai Finance (DOF) during the Dubai FinTech Summit, is part of the emirate’s broader ambition to become one of the world’s leading cashless and digitally connected economies.
Under the agreement, residents and businesses will eventually be able to pay government fees using crypto wallets linked to Crypto.com’s platform. The exchange will convert the digital assets into Emirati dirhams before transferring the funds to Dubai government accounts, allowing the state to integrate crypto payments without directly holding volatile digital currencies.
The programme forms a central pillar of Dubai’s Cashless Strategy, which targets more than 90% of all financial transactions across the public and private sectors becoming cashless by 2026. Dubai officials estimate the strategy could contribute at least AED 8 billion annually to the local economy through fintech expansion and digital payment innovation.
Dubai Finance described the agreement as a “global first” for comprehensive government-wide crypto payment integration. The deal was signed by Ahmad Ali Meftah, Executive Director of the Central Accounts Sector at DOF, and Mohammed Al Hakim, President of UAE Operations at Crypto.com UAE, which operates under a licence issued by Dubai’s Virtual Assets Regulatory Authority (VARA).
Founded in 2016, Crypto.com is one of the world’s largest digital asset platforms, serving more than 100 million users globally across trading, payments, and digital financial services. The company has aggressively expanded in the Middle East as regional governments position themselves as hubs for digital assets and blockchain innovation.
Dubai officials framed the partnership as part of a wider economic transformation strategy under the Dubai Economic Agenda D33, a long-term plan aimed at doubling the size of Dubai’s economy over the next decade and strengthening its role in global trade and technology.
Abdulla Mohammed Al Basti, Secretary General of The Executive Council of Dubai, said the adoption of secure cryptocurrency payment infrastructure reflects Dubai’s effort to anticipate future economic and financial trends while improving the efficiency of government transactions.
DOF Director General Abdulrahman Saleh Al Saleh added that the agreement aligns with Dubai’s push to strengthen its position in digital payments and accelerate the development of a modern financial ecosystem supported by public-private partnerships.
For Crypto.com, the partnership represents another major institutional milestone as crypto firms increasingly seek regulatory legitimacy and real-world payment adoption beyond trading activity. Eric Anziani, President and COO of the exchange, described the initiative as one of the first large-scale examples of crypto-enabled payment digitisation across an entire government framework.
The agreement also highlights the UAE’s growing role in global digital asset regulation. Over the past several years, Dubai has introduced dedicated crypto licensing rules through VARA, attracting exchanges, blockchain firms, and Web3 startups seeking clearer regulatory environments than those available in some Western jurisdictions.
While the technical rollout timeline has not yet been finalised, the government said implementation will begin once integration and compliance arrangements are complete. Officials emphasised that the system will operate within a secure and regulated payment framework designed to support both consumer protection and transaction efficiency.
The move places Dubai among a small group of governments experimenting with direct crypto integration into public-sector payment systems, signalling how digital assets are increasingly being tested as part of mainstream financial infrastructure rather than remaining limited to speculative investment markets.
Europe's central bank is using blockchain to tear down its own financial walls
In a continent where a single stock trade can touch 28 separate depositories, 14 clearing houses, and 295 trading venues before it settles, Christine Lagarde has a pointed argument: the plumbing needs to be rebuilt, and blockchain is the tool to do it.
The problem in plain numbers
The European Central Bank (ECB) is the central bank for the 20 eurozone countries and the institution responsible for monetary policy across the EU's single currency bloc. Its president, Christine Lagarde — a former French finance minister and IMF Managing Director — has spent the past two years making an unusually direct case for radical financial infrastructure reform. Last week she did so again, this time at the Banco de España LatAm Economic Forum in Spain, in a speech officially titled "Stablecoins: Decoding Money's Future Functions."
The speech had a headline-grabbing statistic buried in its middle section. In 2023, Lagarde noted, the EU had 295 trading venues, 14 central counterparties (the institutions that sit between buyers and sellers to absorb default risk), and 32 central securities depositories — the entities that hold and record ownership of stocks and bonds. The US, by contrast, operates with just two clearing houses and a single depository: the Depository Trust Company (DTC), a subsidiary of DTCC, which alone held more than $100 trillion in assets under custody as of mid-2025, and settled $3.7 quadrillion in transactions in 2024. All 28 EU depositories combined held approximately €80 trillion at the end of 2024 and settled €2.09 quadrillion in 2024.
That comparison is not incidental. It is Lagarde's core argument for why Europe, more than any other major financial bloc, stands to gain from a technology shift.
What Lagarde actually means by DLT
When Lagarde says distributed ledger technology "offers a real path towards integration", she is not proposing that Europe abolish its 28 national depositories by regulatory decree. That would require harmonising 27 separate national bodies of company law, insolvency rules, and tax codes — a political project of enormous complexity that has stalled repeatedly for decades.
Her argument is more surgical. Today, a cross-border securities transaction in Europe must be routed through a chain of national institutions — each with its own settlement system, reconciliation process, and legal framework — because every layer of the infrastructure was built before the single market existed, and remains nationally anchored. It works, but it is slow, expensive, and redundant by design.
What blockchain-based infrastructure enables, she argues, is something different: the ability to build from scratch, on a shared ledger, where the issuance, trading, settlement, and custody of a security can all take place on the same platform simultaneously, accessible across borders, without routing through any of that national machinery. This concept — known as atomic settlement — means both legs of a transaction (the security transferred and the cash paid) settle at exactly the same moment on the same ledger, eliminating settlement risk entirely.
The implication is not that the old institutions disappear, but that new transactions no longer need them.
From theory to infrastructure: Pontes and Appia
The ECB is not waiting for legislation to catch up. Two concrete projects are already underway, announced under the Eurosystem's broader strategy approved by the ECB's Governing Council in 2025.
Pontes — Latin for "bridges" — is the immediate step. It will connect DLT-based market platforms directly to the Eurosystem's existing TARGET payment infrastructure, enabling participants to settle tokenised financial instruments in central bank money — the "safest" possible settlement asset — rather than in private stablecoins or commercial bank deposits. A pilot is scheduled to launch in the third quarter of 2026. The design builds on a large-scale exploratory exercise the ECB ran between May and November 2024, in which 64 institutional participants conducted over 50 trials and experiments, settling approximately €1.6 billion in transactions. That exercise tested three different interoperability approaches and directly shaped the architecture of Pontes.
Appia is the longer-term track, and the more ambitious one. Published in March 2026, the Appia roadmap sets out the path to a fully interoperable, European, tokenised financial ecosystem, with a blueprint to be delivered in 2028 in collaboration with market participants, legislators, regulators, and academia. The six building blocks under development span technical standards, interoperability, collateral management, cross-border connectivity, and the legal and regulatory foundations required to make a genuinely integrated system function. Crucially, the ECB has already made a first regulatory concession to the new world: from March 2026, DLT-based assets issued in central securities depositories became eligible as collateral for Eurosystem credit operations. In practice, this means banks can begin using some tokenized securities in the same way they use traditional financial assets to access liquidity from the eurozone’s central banking system.
The two projects are explicitly designed to evolve together. Pontes is not a permanent destination: the ECB has said it will gradually be enhanced and eventually absorbed into the Appia ecosystem once the broader blueprint is finalised.
The stablecoin argument — and what Lagarde rejects
The speech's ostensible subject is stablecoins, and Lagarde's position deserves precision, because it is commonly misread as straightforward hostility.
Her actual argument is that the debate around stablecoins conflates two distinct things: a monetary function (extending the reach of a currency, particularly the dollar, across borders) and a technological function (providing a native settlement asset on DLT-based platforms, enabling atomic settlement). These are not the same, and treating them as one leads to a muddled policy response.
On the monetary side, Lagarde is sceptical of the case for a European stablecoin as a geopolitical counterweight to dollar-denominated instruments. Stablecoins currently account for just 0.01% of global business-to-business payment flows, and converting in and out of them carries costs that erode the efficiency gains.
On the technological side — where the real case for stablecoins lies — her argument is that Europe does not need private stablecoins to obtain those benefits. Central bank money, made available natively on DLT platforms through Pontes, can perform exactly the same settlement function with none of the financial stability or monetary sovereignty risks. That is the purpose Pontes is designed to serve: ensuring that as financial markets migrate onto tokenised infrastructure, the settlement asset at the heart of those markets remains a euro issued by the ECB, not a dollar-backed token issued by a private company.
What this means in practice
The ECB's strategy is a direct response to a structural vulnerability. As tokenised assets grow — a market that grew from approximately $5.5 billion at the start of 2025 to over $20 billion by January 2026, according to Securitize's year-end review" — market participants default to whatever settlement asset is available on-chain. Today, that is overwhelmingly dollar-denominated stablecoins, controlled by two private issuers. If that pattern solidifies, Europe's financial infrastructure could become operationally dependent on instruments it does not control and does not regulate.
Pontes and Appia are designed to prevent that outcome by ensuring a credible European alternative exists before the market's habits become entrenched. Whether a pilot system connecting to existing TARGET infrastructure will be attractive enough to shift behaviour away from more liquid private instruments by Q3 2026 is a genuinely open question. Several in the industry have noted that the timeline — announced in July 2025 and widely considered ambitious — means the window between now and launch is short, and the risk of losing market momentum is real.
What is clear is the direction. Lagarde closed the relevant section of her speech with a single sentence:
"Europe succeeded in building a single currency. It can also build a single digital financial market to stand alongside it."
The infrastructure to attempt it is now, at least on paper, under construction.
The U.S. Senate just passed its most important crypto bill in history — but the hard part starts now
The Digital Asset Market Clarity Act clears a key Senate committee, drawing the crypto industry one step closer to federal regulation — and igniting a fierce political battle over ethics, consumer protection, and presidential conflicts of interest.
On May 14, 2026, the U.S. Senate Banking Committee voted to advance the Digital Asset Market Clarity Act — widely known as the CLARITY Act — by a 15-9 vote, with Democratic Senators Ruben Gallego of Arizona and Angela Alsobrooks of Maryland joining all Republicans on the panel to push it forward. The crypto industry's primary goal in Washington has taken a major step forward, with the passage of the bill through a committee process after months of negotiations and delays.
What is the CLARITY Act?
The CLARITY Act is the most ambitious attempt yet to bring the U.S. crypto industry under a coherent federal framework. It would give the CFTC primary oversight authority over many digital commodities and related trading platforms, while the SEC would retain jurisdiction over digital asset securities.
In plain terms: until now, crypto companies have operated in what Chairman Tim Scott described as a "regulatory gray zone" under "outdated rules." The bill aims to end that ambiguity by drawing clear lines between who regulates what — and how.
Beyond jurisdiction, the bill also classifies many digital assets as commodities, includes provisions intended to limit liability exposure for some decentralized finance software developers and infrastructure providers, establishes stablecoin rules, and limits the potential creation of central bank digital currencies (CBDCs).
Why this vote matters
The CLARITY Act has been years in the making. The House passed its version of the bill (H.R. 3633) by 294-134 in July 2025. Thursday's Senate Banking Committee vote is a major milestone, but it is not the finish line.
The bill now needs to be merged with a related bill approved by the Senate Agriculture Committee, then advance to a full Senate floor vote before eventually returning to the House for final passage — a multi-step process facing a tight legislative calendar.
Critically, if the Senate fails to pass the bill this year, when November midterm elections could see Democrats take the House, it is unlikely to become law in the foreseeable future, according to analysts.
Who is driving It — and who is paying for it
The bill is backed by some of the largest players in the crypto industry. Coinbase, Circle, and Ripple are among the companies that have championed it, arguing that clear oversight rules would encourage broader investor participation. Venture capital heavyweight Andreessen Horowitz is also a key supporter.
The crypto industry spent more than $119 million backing pro-crypto candidates during the 2024 election cycle, according to Reuters. The White House has also been an active force: it has pushed for the bill, at times becoming directly involved in negotiations between banks and crypto groups.
The opposition: Warren fires back
Not everyone is celebrating. Senator Elizabeth Warren, the ranking member of the Senate Banking Committee, led the Democratic opposition with sharp criticism.
Warren argued the committee should be focused on groceries, health costs and credit card rates — not "a bill written by the crypto industry for the crypto industry." She warned that the draft weakens securities law that has protected investors since 1929, preempts state anti-fraud rules, and allows banks to take on volatile crypto exposure in ways reminiscent of pre-2008 practices.
Her most pointed attack targeted the absence of ethics provisions in the bill. Warren noted that "in just one year in office, the President and his family have raked in at least $1.4 billion in gains from crypto deals alone, and yet this bill stunningly includes zero provisions to prevent that."
The conflict-of-interest section — which would limit government officials from profiting from the crypto industry — falls outside the Senate Banking Committee's jurisdiction, meaning it cannot be inserted at this stage and must be added later. Several Democrats, including Senator Kirsten Gillibrand, have said they will not support the bill on the Senate floor without such language.
The stablecoin flashpoint
One of the most contentious technical debates in the bill surrounds stablecoins — digital tokens pegged to stable assets like the U.S. dollar. Banks have opposed provisions allowing crypto firms to offer certain rewards tied to stablecoin activity, arguing the measure could encourage consumers to move deposits away from traditional banking institutions.
On May 9, the three largest U.S. banking trade groups — the Independent Community Bankers of America, the Bank Policy Institute, and the American Bankers Association — formally rejected the stablecoin compromise embedded in the CLARITY Act, calling it unacceptable. Despite that pushback, the markup proceeded as scheduled.
What happens next
The road ahead remains difficult. The bill needs at least seven Democratic votes to overcome a Senate filibuster — and as of today, only two Democrats on the committee voted in favour. Senator Alsobrooks, one of the two Democrats who voted yes, said she would not support the bill on the Senate floor until outstanding issues are addressed.
Chairman Scott called it "one of the most informative and challenging processes" he has been through as a senator, while expressing confidence that both parties would continue working to resolve the remaining disagreements.
The next steps: merging the Senate Banking and Agriculture Committee versions, negotiating the ethics provision, and finding enough bipartisan support to reach the 60-vote threshold on the Senate floor — all before the summer recess cuts the legislative window short.
For the crypto industry, this is the closest the United States has ever come to a comprehensive rulebook. Whether it becomes law in 2026 depends on whether Washington can bridge a political divide that, for now, remains very much open.
Kraken ditches LayerZero for Chainlink to secure its wrapped Bitcoin — and it's not alone
A $292 million exploit in April has triggered a mass exodus from LayerZero. Kraken is the latest major exchange to pull the plug.
On May 14, 2026, Kraken — one of the world's largest cryptocurrency exchanges, founded in 2011 and serving tens of millions of users globally — announced it will migrate its wrapped Bitcoin product, kBTC, from LayerZero to Chainlink's Cross-Chain Interoperability Protocol (CCIP), designating it the exclusive cross-chain infrastructure for kBTC and all future Kraken wrapped assets.
What is kBTC?
It is a token that represents Bitcoin on other blockchains, allowing Bitcoin holders to use their assets in decentralised finance (DeFi) without selling their BTC. Kraken introduced kBTC in 2024 as a 1:1 bitcoin-backed token available first on Ethereum and OP Mainnet. The token now has a market capitalisation of approximately $260–$266 million. Holders of kBTC do not need to take any action — Kraken will manage the migration process entirely.
Why the switch? A $292 million wake-up call
The trigger is clear. On April 18, a $292 million exploit of Kelp DAO resulted in losses tied to a LayerZero-powered bridge. A LayerZero postmortem acknowledged it "made a mistake" in the configuration used by Kelp DAO, with attackers able to poison internal RPCs used by its system and withdraw 116,500 rsETH liquid staking tokens. The attack was later attributed to North Korea's Lazarus Group.
Rather than wait for reassurances, Kraken chose to act. The exchange cited Chainlink CCIP's ISO 27001 and SOC 2 compliance certifications, its network of 16 independent node operators, and native rate limits as key factors in its decision. In Kraken's own words, according to Yahoo Finance report:
"Kraken chose Chainlink CCIP because it offers enterprise-grade infrastructure with strict security & risk management requirements".
Kraken is far from alone
The Kelp exploit has set off what is shaping up to be a structural shift in how the industry handles cross-chain infrastructure. Kelp DAO, Solv Protocol, and on-chain reinsurance protocol Re have all announced moves toward Chainlink CCIP. Solv Protocol plans to shift infrastructure supporting more than $700 million in tokenised Bitcoin. In total, an estimated $3 billion in total value locked has migrated since the Kelp exploit. Rival exchange Coinbase also selected Chainlink CCIP last year as the sole bridge for approximately $7 billion in wrapped tokens.
What is Chainlink, and why is it winning?
Chainlink is best known as the dominant decentralised oracle network — the infrastructure that feeds real-world data into blockchains. It has since expanded into cross-chain infrastructure through CCIP. Chainlink says CCIP has supported over $28 trillion in cumulative on-chain transaction value. The protocol offers a defence-in-depth architecture, built-in rate limits, independent node operators, and formal security certifications including ISO 27001 and SOC 2 Type 2 compliance — the kind of institutional-grade credentials that exchanges now demand after years of bridge exploits.
Since 2021, cross-chain bridge hacks have resulted in losses exceeding $2.5 billion industry-wide, including the Ronin Bridge ($620M), Wormhole ($326M), and Nomad ($190M). Against that backdrop, Kraken's decision is less of a surprise and more of a logical conclusion.
What it means for LayerZero
LayerZero's token (ZRO) faces headwinds as the loss of a top-tier exchange partner signals a dent in institutional trust. The protocol insists its core code was not compromised in the Kelp incident, but the reputational damage from a string of high-profile departures is real and accumulating.
The bigger picture
This story is not just about one exchange swapping one piece of plumbing for another. It signals a maturing industry in which security infrastructure is now treated with the same rigour as custody. Cross-chain bridges remain one of the largest sources of losses in crypto markets, and interoperability standards are becoming central to tokenised asset markets and multi-chain finance. For Kraken, anchoring kBTC to Chainlink's infrastructure is also a strategic bet: the more securely Bitcoin can travel across chains, the more useful kBTC becomes as collateral and liquidity across DeFi.
The LayerZero fallout, it seems, is still spreading.
