Structuring an alternative investment fund (AIF – a pooled investment vehicle for professional or institutional capital) for digital assets in the United States is one of the most consequential decisions a fund manager makes. The federal securities regime administered by the SEC (Securities and Exchange Commission) and the CFTC (Commodity Futures Trading Commission) applies the moment the fund pools outside capital into tokens that qualify as securities or commodity interests. Simultaneously, the state-level money transmitter licensing (MTL) regime – enforced by individual state regulators and, at the federal level, by FinCEN under the Bank Secrecy Act – reaches any operational activity that touches the transmission or custody of digital assets. This page maps the regulated perimeter, the structural options, and the decision points that determine whether a US-domiciled or US-accessed crypto fund can operate efficiently.
Why domicile and registration decisions are linked for a digital-asset fund
The domicile of a fund and the registration obligations of its manager are distinct legal questions – but in the US market they pull on each other in ways that catch many operators off-guard. A Delaware limited partnership or a Delaware LLC is the workhorse structure for US-based fund vehicles. Delaware offers a well-developed body of partnership law and predictable governance mechanics. That structural choice does not, however, determine whether the manager must register with the SEC, whether the fund qualifies for an exemption under the Investment Company Act, or whether activities of the fund or its administrator trigger state MTL requirements.
The SEC's investment adviser registration regime applies to managers above a threshold assets-under-management level, subject to state versus federal jurisdiction. Below that threshold, state investment adviser registration may apply instead – and each state has its own variation. Managers relying on the private fund adviser exemption must still file as exempt reporting advisers with the SEC. The key point: the registration path turns on AUM, number of clients, and the type of assets managed, not simply on where the fund entity is formed.
In our cross-border practice, we regularly see managers who domicile offshore – in the Cayman Islands or BVI – to access a broader investor base, then raise capital from US persons through a parallel US feeder fund or side-pocket arrangement. That two-vehicle approach triggers its own registration and reporting requirements. Getting the structure right at the outset avoids mid-cycle restructuring costs that can far exceed the initial legal spend.
The wrong domicile locks in tax leakage and limits which investors you can accept. A domestic LP that inadvertently takes in ERISA-plan investors above the "benefit plan investor" threshold, for example, converts the manager into a fiduciary with materially different obligations. These are avoidable structural errors.

Which federal regimes apply to a crypto AIF in the US?
Three distinct federal regimes apply to a digital-asset AIF in the United States, and their scope turns on the nature of the assets held, not on the label the manager assigns them. The SEC governs funds that hold securities – including tokens the Commission characterizes as investment contracts under the longstanding Howey analysis. The CFTC governs funds that trade commodity interests, including Bitcoin and Ether, which both agencies have treated as commodities in various contexts. FinCEN's Bank Secrecy Act obligations attach to any entity that qualifies as a money services business.
The Investment Company Act imposes stringent registration, reporting and governance obligations on any entity that meets the definition of an investment company. Most private crypto funds rely on one of two exclusions: the exclusion for funds with no more than 100 beneficial owners that do not make a public offering, or the exclusion for funds whose investors are exclusively qualified purchasers. The second exclusion is broader in terms of investor count but imposes a higher wealth threshold on each investor. Which exclusion to rely on determines the investor composition the fund can accept and directly affects its ability to scale.
Under the Investment Advisers Act, the manager of a private fund relying on those exclusions typically files as an exempt reporting adviser with the SEC, unless AUM exceeds the threshold that triggers full registration. Full registration brings Form ADV disclosure obligations, a compliance programme requirement, books-and-records rules, and examination risk. Managers in our practice who manage funds above the registration threshold – and particularly those managing a mix of liquid tokens and less-liquid positions – invest significantly in the compliance infrastructure required to sustain that registration.
How does state money transmitter licensing intersect with a crypto fund?
State MTL requirements create a parallel layer of obligation that is frequently underestimated at the fund formation stage. The threshold question is whether any activity of the fund, its manager, or its administrator constitutes "money transmission" under state law. In many states, transmitting virtual currency on behalf of others – including processing subscriptions and redemptions denominated in digital assets – falls within the statutory definition.
New York's BitLicense, issued by the NYDFS (New York State Department of Financial Services), is the most demanding state-level regime. It covers virtual currency business activity conducted with or on behalf of New York residents. A fund that accepts subscriptions from New York investors in USDC, or that redeems investors into BTC, may be conducting virtual currency business activity within the NYDFS perimeter – regardless of where the fund is domiciled. Several other states have enacted their own VASP or money-transmitter frameworks, each with its own carve-outs, thresholds and timelines.
The interaction of federal and state MTL regimes creates a compliance matrix that must be mapped before the fund accepts its first subscription. Operators we advise routinely discover that a fund structured for tax efficiency – say, a Cayman master with a Delaware feeder – must still analyse MTL exposure in every state where investors reside or where operational activity occurs. That analysis is not a one-time exercise; state legislatures continue to amend their digital-asset frameworks, and the MTL map changes as the fund's investor geography evolves.
FinCEN registration as a money services business is a separate, federal-level obligation that applies to certain money transmitters regardless of state licensing. A fund that transmits value in crypto may need to register with FinCEN and implement a full Bank Secrecy Act compliance programme including AML policies, SAR filing protocols, and – where applicable – Travel Rule (the obligation to pass originator and beneficiary data with a qualifying transfer) compliance procedures.
What structural options suit different crypto fund profiles?
The right fund vehicle depends on the investor base, the asset mix, the manager's own regulatory footprint, and the tax profile of the capital. There is no single default structure that works across profiles.
Profile A – US manager, primarily US institutional investors, trading liquid tokens classified as commodities. A Delaware limited partnership with a commodity pool operator (CPO) registration or exemption before the CFTC is the standard starting point. The fund relies on a qualified purchaser exclusion from the Investment Company Act. The manager files as an exempt reporting adviser or registered investment adviser with the SEC depending on AUM. MTL exposure is assessed state by state based on the fund's operational footprint. Timeline to operationalize this structure – from formation through regulatory filings – is typically a matter of months, not weeks.
Profile B – Non-US manager, seeking access to US investors alongside a global investor base. A master-feeder structure with an offshore master (Cayman or BVI) and a Delaware or Cayman feeder for US persons is the conventional approach. The US feeder must comply with SEC reporting obligations and, depending on AUM channelled through it, may require the manager to register or file as an exempt reporting adviser in the US. ERISA and qualified purchaser thresholds apply to the US feeder independently. Banking the US feeder adds a further constraint: US correspondent banks apply their own digital-asset policies, which can be more restrictive than the regulatory floor.
Profile C – Digital-asset fund manager seeking a lean first structure to test the market. A Regulation D private placement through a domestic LLC or LP, relying on the 100-beneficial-owner or qualified purchaser exclusion, is the fastest path to a compliant US fund. The manager typically files as an exempt reporting adviser. This profile defers the MTL analysis to the extent the fund's operational activity does not constitute transmission – which requires careful product design around how subscriptions and redemptions are processed and in what assets.
In a recent matter, a token-strategy manager structured an offshore master with a US feeder, then expanded into additional US states as its investor base grew. The MTL analysis that had cleared at launch needed refreshing at the point of expansion. We worked through the updated state-by-state map and identified two states where the expanded operational model required additional registration before the fund accepted new subscriptions from those residents. The expanded structure was operational within the quarter.
What is the cross-border tax and banking interaction for a US digital-asset fund?
Tax and banking are the two pressure points that most often break a fund structure that is otherwise legally sound. Both must be mapped at the design stage, not retrofitted after launch.
On the tax side, US taxable investors in a fund that trades digital assets will typically receive partnership income reported on Schedule K-1. The characterization of that income – ordinary income, capital gain, or a mix – depends on the trading strategy and holding periods, and is heavily fact-specific. US tax-exempt investors, including pension funds and endowments, are sensitive to unrelated business taxable income (UBTI) generated by leveraged positions. Offshore investors in a US fund face US withholding tax considerations on certain income streams. A Cayman or BVI master structure insulates offshore investors from those US withholding exposures, but creates its own reporting obligations under FATCA and the OECD Common Reporting Standard.
On the banking side, US banks remain the most restrictive participants in the digital-asset space. A fund manager seeking a business account for a crypto AIF will encounter enhanced due diligence requirements, extended onboarding timelines, and – in some cases – outright declines from institutions that have withdrawn from digital-asset client relationships. Managers we advise frequently maintain a combination of a US account for dollar operations and an account with a more crypto-friendly institution in a jurisdiction such as Switzerland, Singapore or the UAE for crypto-side operations. The cross-border banking structure must align with the fund's AML programme and its obligations under FATCA reporting rules.
The interaction between US tax reporting – particularly PFIC (passive foreign investment company) rules for US investors in offshore funds – and the token classification debate adds further complexity. A token that is later characterized as a security by the SEC may need to be reclassified in the fund's tax reporting. Managers should build scenario flexibility into the tax reporting infrastructure from day one.

How do US AML and Travel Rule obligations apply to a crypto fund?
AML obligations for a digital-asset fund in the US flow from two sources: FinCEN's Bank Secrecy Act framework and the fund's own state-level MTL compliance obligations. The threshold question is again whether the fund's operational activity constitutes money transmission or a money services business activity. Where it does, a written AML programme, a designated compliance officer, ongoing transaction monitoring, and SAR filing protocols are non-negotiable.
The Travel Rule – derived from FATF Recommendation 15 on virtual assets – requires certain transferring entities to pass originator and beneficiary identifying information alongside qualifying virtual asset transfers. FinCEN has proposed rulemaking that would extend Travel Rule obligations explicitly to funds and their service providers in certain circumstances. The current position is that funds which are not themselves money services businesses may rely on their custodians and prime brokers to carry Travel Rule compliance – but that reliance must be documented and auditable. Regulators in the major hubs increasingly expect the fund manager to verify that its service-provider chain is Travel Rule-compliant, not merely to assume it.
OFAC sanctions screening is a parallel obligation that applies regardless of MSB status. A fund trading digital assets must screen counterparties, wallet addresses, and service providers against the OFAC Specially Designated Nationals list. Tether (USDT) and Circle (USDC) both maintain contract-level freeze capability and act on OFAC designations; a fund holding stablecoins should account for the scenario in which a holding is frozen at the issuer level without prior notice.
Self-assessment checklist for a US digital-asset AIF
Before engaging counsel to form the fund, a manager should be able to answer the following questions. Where the answer is "uncertain," that gap is the legal workstream.
- Are the tokens in the proposed portfolio securities, commodity interests, or neither – and on what analysis?
- Which Investment Company Act exclusion will the fund rely on, and does the target investor base fit that exclusion?
- Does the manager's projected AUM place it in the SEC-registered, state-registered, or exempt-reporting category?
- Does any element of the fund's subscription, redemption or operational activity constitute money transmission in any state where investors reside?
- Is the manager's activity in New York – even indirectly, through New York investors – sufficient to bring it within the NYDFS BitLicense perimeter?
- Does the fund's structure require CPO or commodity trading adviser (CTA) registration or exemption before the CFTC?
- Is the fund's banking strategy mapped to both the dollar-side and the crypto-side of operations?
- Are FATCA and PFIC reporting obligations built into the fund's tax infrastructure for offshore and US taxable investors respectively?
- Is the AML programme – including OFAC screening and Travel Rule coverage – either in-house or delegated to a documented and auditable service provider?
A common assumption about offshore vehicles and US access
A common assumption among fund managers entering the US market is that any offshore vehicle works equally well as a foundation for a digital-asset fund – that the Cayman Islands and the BVI are interchangeable, that a foreign vehicle can simply accept US investors without further structure, or that offshore domicile removes the need for US regulatory analysis. None of those assumptions hold.
The US regulatory perimeter is unusually extraterritorial. The SEC and CFTC assert jurisdiction based on where investors are located and where economic activity has a substantial effect in the United States – not merely where the fund entity is formed. A Cayman fund with predominantly US investors is firmly within the US regulatory perimeter for purposes of the Investment Company Act exclusion analysis, securities offering registration, and adviser registration. The offshore domicile affects tax treatment and certain investor eligibility rules; it does not remove the US regulatory overlay.
Similarly, the NYDFS BitLicense applies to virtual currency business activity conducted with or on behalf of New York residents, wherever the entity conducting that activity is formed. An offshore fund that redeems New York investors in Bitcoin is conducting virtual currency business activity in the NYDFS view. The manager's response to that risk – whether to apply for a BitLicense, to structure around it, or to exclude New York investors – is a deliberate legal decision that must be made with full information, not discovered during a regulatory examination.
In our cross-border practice, we regularly advise fund managers who have launched offshore vehicles and subsequently discovered the extent of their US exposure. The restructuring cost – in legal fees, investor consent solicitations, and regulatory filings – is multiples of what a properly structured initial design would have cost.

FAQ
Where should a crypto fund be domiciled?
Domicile depends on four variables: the investor base, the asset mix, the manager's own regulatory footprint, and the tax profile of the capital. US-based managers with primarily US institutional investors typically use a Delaware limited partnership. Managers seeking offshore optionality – for non-US investors or tax efficiency – commonly use a Cayman or BVI master fund alongside a US feeder. No single domicile is universally optimal. The right answer maps the specific investor composition to the regulatory and tax consequences in each candidate jurisdiction.
Does a digital-asset fund manager need a licence?
In the US, "licence" is the wrong frame. The relevant questions are: must the manager register with the SEC as an investment adviser or file as an exempt reporting adviser; must it register with the CFTC as a commodity pool operator or commodity trading adviser; and does any operational activity trigger state money transmitter licensing, including the NYDFS BitLicense? Each of those obligations has its own threshold, exemption and filing regime. A manager that crosses any of those thresholds without addressing the relevant registration faces material enforcement risk.
How is custody arranged for a crypto fund?
A registered investment adviser holding client assets in digital form is subject to the SEC's custody rule, which requires assets to be held with a qualified custodian. Not all crypto custodians meet the qualified custodian definition. Managers must vet custodians against the rule's requirements and document that analysis. For funds relying on an Investment Company Act exclusion and not registered as investment advisers, custody arrangements are governed by the fund's governing documents and the contractual terms with the custodian – but institutional investors increasingly require a qualified-custodian-equivalent standard as a term of their subscription.
