Tokenized money market funds (TMMFs) are easy to confuse with stablecoins because both can appear as tokens in a wallet. But they are different products. A tokenized money market fund usually represents a fund share or fund interest, not cash held directly on-chain.
This guide explains what tokenized money market funds are, what you may own, how they work, and how they differ from stablecoins, tokenized Treasuries, and tokenized deposits.
KEY TAKEAWAYS
➤ TMMFs represent fund shares or fund interests through blockchain-based records, not cash held directly on-chain.
➤ Investor rights depend on fund documents, the official ownership record, and transfer agent rules, not just the token.
➤ Most products restrict transfers to approved wallets and require identity verification before access.
➤ These products differ from stablecoins, tokenized Treasuries, and tokenized deposits in legal form, income treatment, and redemption process.

What is a tokenized money market fund?
A tokenized money market fund (TMFF) is a money market fund whose shares or fund interests are represented through blockchain-based records or tokens. It gives holders exposure to a traditional money market fund structure, while the blockchain layer records or helps transfer the ownership position.
The token is not the whole product. Your rights still depend on the fund documents, the official ownership record, the transfer agent, the wallet rules, and the redemption terms.
BlackRock’s SEC filing for the Daily Reinvestment Stablecoin Reserve Vehicle shows how this works in practice. Its proposed OnChain Shares use approved wallets and off-chain identity records, while Securitize, the fund’s transfer agent, maintains the system through a permissioned blockchain-linked structure.
What money market funds usually hold
Money market funds usually invest in short-term, liquid assets such as Treasury bills, government securities, repurchase agreements, cash, and cash equivalents. These assets help the fund target liquidity, capital preservation, and income tied to short-term rates.
According to Investor.gov, money market funds have relatively low risks compared to other mutual funds but have historically delivered lower returns.
Many money market funds seek to keep their net asset value (NAV) at $1.00 per share, but that value is not guaranteed. Some fund types use a floating NAV, which means the share price can move above or below $1.00.
This base is important for tokenized money market funds because the blockchain layer may change how fund shares are recorded or transferred, but the fund still depends on traditional short-term assets.
Money market funds are not bank deposits. They carry no FDIC insurance. Even funds targeting a $1.00 net asset value (NAV) can break that threshold under stress conditions, an event historically called “breaking the buck.”
Traditional money market fund vs. tokenized money market fund
| Traditional MMF | Tokenized MMF |
|---|---|
| Ownership tracked through traditional fund records | Ownership represented through blockchain-based records or tokens |
| Transfers follow traditional financial infrastructure | Transfers may occur through approved blockchain wallets |
| Settlement usually follows standard market hours | Some systems support near-24/7 transfer and collateral workflows |
| Access depends on fund rules | Access depends on fund rules plus wallet eligibility |
What tokenization changes in a money market fund
Tokenization changes only the record and transfer layer of a money market fund. It doesn’t put the fund’s assets on-chain. The fund may still hold Treasury bills, repurchase agreements, cash, and cash equivalents through traditional custody arrangements.
The European Central Bank defines tokenized money market funds as money market funds whose shares are issued as tokens on distributed ledgers. It also notes that fund assets often remain off-chain.
In simple terms, the token represents the claim. It does not turn the fund’s cash, repos, or Treasury holdings into blockchain-native assets.
| Layer | What it does |
|---|---|
| Fund layer | Holds cash, Treasury bills, repos, or other short-term assets |
| Token layer | Represents fund shares or fund interests through blockchain-based records |
| Official record | Confirms who owns the position and what rights apply |
| Transfer rules | Decide which wallets can hold, receive, or transfer the token |
So, a tokenized money market fund token can therefore appear in a wallet, but wallet possession is not the full legal story. Legal rights flow from the fund documents, official ownership record, transfer agent rules, and redemption terms.
The BIS noted in November 2025 that TMMFs can circulate on public blockchains while offering money market-style returns and securities-law protections. That combination helps explain why they differ from stablecoins.
A stablecoin usually serves as a payment or settlement asset. A tokenized money market fund usually represents a regulated fund position with its own access, transfer, income, and redemption rules.
How tokenized money market funds work
The operating flow for a tokenized money market fund has five steps, but the process is more controlled than a typical crypto transaction.
Step 1: Eligibility and KYC. Before any wallet receives tokens, the investor passes identity verification, know-your-customer (KYC) checks, and anti-money laundering (AML) screening. Most products restrict access to qualified or institutional investors in specific jurisdictions.
Step 2: Wallet approval. The investor’s blockchain wallet is registered or “allow-listed.” This is a critical difference from permissionless crypto assets. The BIS bulletin on TMMFs notes that these products rely on the allow-listing of blockchain wallets to constrain peer-to-peer trading and meet regulatory compliance requirements. An unapproved wallet cannot receive or hold the tokens.
Step 3: Subscription. The investor sends cash, stablecoin, or another approved instrument to subscribe to the fund. The accepted payment method depends on the product. Some accept only fiat wire transfers, others accept USDC, and some accept both.
Step 4: Token issuance. The fund issues tokenized shares or updates a blockchain-linked ownership record. The BlackRock SEC document for OnChain Shares describes Securitize Transfer Agent as maintaining the official record through a permissioned system connected to public blockchains, with wallets linked to off-chain identity records.
The token in the wallet reflects the position, but the transfer agent’s system is the authoritative source.
Step 5: Hold, transfer, or redeem. The investor may hold the position, transfer it to another approved wallet, use it as collateral in eligible systems, or redeem it for cash or stablecoin, all subject to the product’s rules. Redemption terms vary significantly. For instance, some products settle same-day, others follow T+1 schedules, and some restrict redemption to business hours or platform-specific windows.
Token transfer does not equal a traditional securities transfer. Moving a TMMF token to a wallet not on the allow list may be blocked at the protocol or transfer agent level. That’s why, you should always verify transfer eligibility before attempting to move fund positions.
What are the different types of tokenized money market funds?
The five-step flow above describes a common setup, but tokenized money market funds do not all work the same way. Treating BENJI, BUIDL, USYC, and BlackRock OnChain Shares as identical products can create confusion because each product uses a different legal and operational structure.
| Model | What it means | Reader takeaway |
| Official blockchain-linked record | The fund’s ownership record uses a blockchain-linked system as the authoritative source | The blockchain record may carry legal weight, but only within the product’s rules |
| Transfer-agent controlled model | A registered transfer agent controls the official record, wallet approval, and corrections | The token is not permissionless; the transfer agent can freeze, revoke, or re-authenticate positions |
| Mirror-record model | The blockchain reflects ownership while a traditional system remains primary | The on-chain record may not be the final legal source of truth |
| Private or offshore fund token | The product is available only to certain investor types or jurisdictions | Access and rights depend on eligibility rules that may exclude retail users |
| Treasury-backed token grouped with TMMFs | The product tracks or holds Treasury assets without being a registered money market fund | Do not assume the product is a regulated money market fund |
Franklin Templeton’s BENJI model illustrates one structure clearly. The Franklin OnChain U.S. Government Money Fund links one FOBXX share to one BENJI token, while the transfer agent maintains the official ownership record through the Benji platform. The blockchain record connects to a registered U.S. mutual fund that operates under SEC rules.
BlackRock’s proposed OnChain Shares structure works differently. Its SEC filing describes a permissioned system where Securitize Transfer Agent maintains the official record and restricts transfers to approved wallets. The wallet token reflects the position, but the transfer agent still controls the authoritative record.
Understanding which model a product uses determines what recourse an investor has, what restrictions apply to transfer, and what happens when something goes wrong. It also prepares you to read the comparison with other product types that follows.
Tokenized money market funds vs. stablecoins and tokenized Treasuries
This is where most confusion starts. The four product types share some surface features. They all live on blockchains and tend to hold dollar-denominated value. But they differ in legal form, income treatment, transfer rules, and redemption mechanics.
| Product | What it usually represents | Main use | Income | Transfer model | Key risk |
| Stablecoin | Token tied to fiat value or reserve assets | Often broader on-chain transfer | Usually no direct issuer-paid yield in regulated structures | Treasury exposure and on-chain yield | Peg, reserve, issuer, and regulatory risk |
| Tokenized money market fund | Fund share or fund interest | Cash management, collateral, yield | Fund income may pass to holders | Usually approved wallets only | Fund, redemption, wallet, and record risk |
| Tokenized Treasury product | Treasury exposure through a fund, note, vault, or token | Treasury exposure and onchain yield | Product-specific | Product-specific | Structure, custody, liquidity, and legal risk |
| Tokenized deposit | Bank deposit represented on distributed ledger systems | Bank settlement and institutional cash movement | Bank deposit terms apply | Usually bank-controlled | Bank, jurisdiction, and access risk |
The ECB’s analysis found that TMMFs primarily serve liquidity management purposes and can distribute yield, whereas stablecoins are mainly used for settling trades in the crypto-asset ecosystem and, in the EU, cannot pay interest under current rules.
That functional difference reflects a bigger legal difference: A TMMF is essentially a security, while a regulated stablecoin is a payment instrument.
At the same time, tokenized Treasury products add another layer of ambiguity. Some, for instance, may represent registered money market fund shares that invest in government securities, while others may represent direct exposure to Treasury bills through a vault, note, or off-chain structure that does not qualify as a registered fund.
The label “tokenized Treasury” covers both, so the underlying legal structure always needs separate verification.
A stablecoin and a tokenized money market fund can both hold a $1.00 value and circulate on the same blockchain. The difference is in what that $1.00 represents, a payment claim or a regulated fund share, and what rights and risks come with it.
Real examples of TMMFs and why institutions use them
The table below covers the most cited products in the category, using publicly available information verified from primary sources. Note that market figures change frequently, so verify current data at RWA.xyz on publication day.
This list is not exhaustive and is intended to show how different tokenized money market fund structures work in practice.
| Product | What it represents | Key point |
| BENJI / FOBXX | Share of Franklin OnChain U.S. Government Money Fund | One FOBXX share equals one BENJI token; transfer agent maintains the official share record through the Benji platform. The fund invests at least 99.5% of assets in U.S. government securities, cash, and repos collateralized by U.S. government securities or cash, per SEC filings. |
| USYC | Tokenized fund product tied to short-duration Treasury and repo exposure | Circle states that USYC yield accrues through a rising token price and offers near-real-time USDC redemptions up to capacity. Each token represents a share of the Hashnote International Short Duration Fund Ltd., a Cayman Islands registered fund, not a U.S.-registered money market fund. Available to non-U.S. persons only. |
| BlackRock OnChain Shares / BRSRV | Proposed OnChain Shares structure per BlackRock’s SEC filing | Securitize Transfer Agent maintains the official ownership record through a permissioned system connected to public blockchains, per the SEC document. Transfers restricted to registered wallets. The fund seeks current income with liquidity and principal stability. |
| BUIDL | BlackRock USD Institutional Digital Liquidity Fund | One of the largest tokenized fund products by assets under management; tokenized by Securitize. Verify current figures via RWA.xyz or official sources before publication. |
These four products represent different legal structures, jurisdictions, yield mechanisms, and access rules:
- BENJI is a U.S.-registered mutual fund.
- USYC is an offshore Cayman Islands fund for non-U.S. persons.
- BlackRock OnChain Shares is a proposed structure still moving through SEC review.
- BUIDL is a private fund for qualified purchasers. The token format looks similar across all four, but what sits beneath it does not.
Institutional demand for these products comes from specific operational needs. Firms managing cash in on-chain environments can hold TMMF positions as yield-bearing collateral, posting them for margin requirements without first liquidating to fiat.
The BIS bulletin describes TMMFs as fast-growing collateral assets in the crypto ecosystem, used particularly by DeFi protocols. Near-24/7 availability also reduces the friction of traditional fund settlement cutoffs for institutions operating across time zones.
Risks of tokenized money market funds
The efficiency features of tokenized money market funds do not eliminate the risks of the underlying fund or the new risks introduced by the blockchain layer. A practical evaluation covers several categories.
- Fund risk: The underlying money market fund can still face liquidity stress, credit events, or redemption pressure. These risks exist whether the shares are recorded on paper or on a blockchain.
- No FDIC guarantee: As Investor.gov states, money market funds are not bank deposits and are not FDIC-guaranteed. Investors can lose money. This applies equally to tokenized versions.
- NAV risk: Even funds targeting a stable $1.00 NAV can break that threshold. BlackRock’s SEC document for OnChain Shares states that the fund may not maintain a stable $1 NAV at all times. Stable NAV is an objective, not a promise.
- Wallet risk: Lost or stolen private keys can create access and recovery problems. The BlackRock SEC document discusses transfer-agent actions, including token freeze, revocation, wallet re-authentication, and token burn, as remedies available in certain situations. Recovery depends on the product’s procedures, not on standard crypto wallet recovery options.
- Redemption versus transferability gap: A TMMF token may be transferable to approved wallets but redeemable only through a specific platform or during certain windows. These two things can diverge in ways that leave holders unable to exit quickly even when they can move the token.
- Legal-structure risk: Holding a token does not automatically mean holding a direct claim on Treasury bills or fund assets. The nature of the claim depends on the fund documents, the jurisdiction, and the official ownership record. Products marketed as giving Treasury exposure may structure that exposure very differently.
- Jurisdiction and eligibility risk: Several products are restricted by investor type, residency, or platform affiliation. USYC, for example, is only available to non-U.S. persons. Accessing a restricted product through a secondary market or an unapproved platform may not carry the same rights as subscribing directly.
Before using any tokenized money market fund, ask these questions. If the product cannot clearly answer these questions, that gap is itself a warning sign:
- What does the token represent?
- Who keeps the official ownership record?
- Can you redeem directly, or only through a specific platform?
- What happens if the wallet key is lost?
- Is the fund registered, private, or offshore?
Tokenized money market funds are one of the clearest examples of traditional fund structures moving onto blockchain-based records. But the token is only one layer. The fund, transfer agent, official ownership record, wallet rules, and redemption terms determine what the holder actually owns and what they can do with it.
The ECB observed as of February 2026 that the TMMF market remains small relative to the broader tokenized asset space and very small compared to traditional money market funds under the EU’s MMFR framework, which stood at roughly 1.73 trillion euros. The structure behind the token matters more than the token itself.
