A digital-asset fund board convening for the first time often arrives at the same disorienting realization: the vehicle that looked optimal at the term-sheet stage is the wrong instrument for the investor base the manager has actually assembled. The wrong domicile locks in tax leakage, restricts which institutional investors can subscribe, and creates friction at the banking layer that no amount of legal ingenuity can fully resolve. With VASP supervision tightening across every major hub and the Alternative Investment Fund (AIF) regime – the regulatory classification applied to collective investment schemes that are not UCITS – now a live question in multiple offshore and onshore centers, boards need a clear-eyed read before they commit.
An AIF for digital assets is a collective investment vehicle, typically structured as a limited partnership or closed-ended company, that pools capital to invest in crypto assets, tokens or related instruments, and that falls outside the retail UCITS wrapper. The applicable regime – whether the AIFMD framework in the EU, the Cayman VASP Act, the BVI VASP Act 2022, or the MAS Payment Services Act in Singapore – determines who can manage it, who can invest in it, and where it can be marketed. This analysis sets out the critical decision points a board must resolve, the cross-border tensions that arise when entity domicile, investor base and asset custody sit in different jurisdictions, and the structural lessons we observe in practice.
Why Domicile Is a Board-Level Decision, Not a Back-Office One
Domicile selection for a digital-asset AIF is not primarily a cost question. It is a legal architecture question that fixes the tax treatment, the investor-marketing perimeter, and the regulatory obligations of the manager simultaneously. Get it wrong at formation and the remediation path – typically a redomiciliation or a parallel master-feeder restructure – is expensive, time-consuming, and occasionally impossible without triggering investor-consent requirements.
The core tension is structural. A Cayman Islands limited partnership delivers broad investor access and a well-understood legal form, but the Cayman VASP Act now imposes registration obligations on funds conducting virtual-asset service activity, and the CIMA regulatory perimeter is evolving. A Luxembourg or Irish AIF accesses EU passporting under the AIFMD framework but requires an authorized alternative investment fund manager (AIFM), carries ongoing cost and reporting burdens, and must navigate MiCA's parallel requirements once the fund trades crypto assets that constitute crypto-assets under that regulation. A BVI structure is lean – governed by the BVI FSC and the VASP Act 2022 – but may create friction with prime brokers and institutional investors running their own AML programs against higher-risk jurisdictions lists.
In our practice, we consistently see managers underestimate the investor-driven constraints. A US-adjacent fund targeting family offices and registered investment advisers faces a different domicile calculus than a fund targeting European insurance capital or Middle Eastern sovereign wealth. The investor base should drive the structure; the structure should never constrain the investor base in ways the manager did not anticipate.
The process above describes the standard architecture decision. Your facts – the entity domicile, the investor list, the asset mix – change the analysis materially. For a scoped domicile assessment, contact OBOLUS at Map your options.
Which AIF Structures Actually Work for Digital Assets?
The primary structures in use for digital-asset AIFs are the Cayman exempted limited partnership, the BVI limited partnership, the Luxembourg special limited partnership (SCSp), the Singapore variable capital company (VCC) and the Cayman segregated portfolio company (SPC) – each with a distinct regulatory and tax footprint.
The Cayman exempted limited partnership remains the dominant global structure for institutional crypto funds. CIMA oversight applies where the fund is registered, and the manager – where non-Cayman – must assess its own licensing position in its home jurisdiction. The structure accepts broad investor categories, has well-established prime-brokerage relationships, and integrates cleanly with BVI general partners.
The Luxembourg SCSp is the EU vehicle of choice for managers who need AIFMD passporting. It requires an authorized AIFM – either internally authorized or a third-party AIFM platform – and imposes full AIFMD depositary, valuation, and reporting obligations. For a digital-asset fund, the depositary obligation creates a practical bottleneck: very few regulated depositaries currently accept crypto assets as depositable assets, meaning the manager must identify a depositary willing to appoint a sub-custodian for the on-chain holdings. This is solvable but adds lead time and cost.
The Singapore VCC, governed by the MAS regime under the Variable Capital Companies Act, offers a flexible multi-class structure with strong institutional credibility in the Asia-Pacific region. A fund manager using the VCC must hold or rely on a holder of a Capital Markets Services licence or a recognized market operator licence from MAS, and the digital-asset components of the portfolio trigger Payment Services Act analysis. We advise fund managers regularly on the interaction between the VCC wrapper and the MAS DPT licensing perimeter.
The Cayman SPC is used where a single management platform runs multiple strategies with legally segregated assets – common in multi-strategy digital-asset platforms. Each segregated portfolio has its own assets and liabilities in law, reducing cross-contamination risk between a liquid-token portfolio and a venture-stage position book.
How Does the AIFMD Framework Interact with MiCA for a Crypto Fund?
For EU-connected digital-asset funds, the intersection of AIFMD and MiCA is the defining regulatory question of the current period. The short answer: the two regimes operate in parallel without a clean carve-out, and a fund can be subject to both simultaneously.
Under the AIFMD framework, a vehicle that pools capital and pursues a defined investment policy is an AIF, and its manager requires authorization as an AIFM by the relevant national competent authority – ESMA coordinates at the European level, but authorization sits with the NCA of the manager's home member state. This obligation applies regardless of whether the assets are equities, real estate, or crypto tokens.
MiCA then layers on top. Where the fund – or its operator – provides crypto-asset services as defined in the regulation (exchange, transfer, custody, or advisory services in relation to crypto assets), a CASP authorization may be required in addition to the AIFM authorization. The critical analytical question is whether the fund's investment activity constitutes a crypto-asset service or is merely incidental to the fund's investment function. ESMA guidance on this boundary continues to develop, and national competent authorities in different member states are taking subtly different initial positions.
In our cross-border practice, we have seen EU fund managers assume that AIFM authorization covers their full regulatory perimeter, only to discover – sometimes after a supervisory query – that their on-chain trading activity or the provision of a token custody service to LPs requires separate CASP authorization. The better practice is to map the activity against both regimes before launching the fund, not after.
What Does the Fund Manager Licensing Stack Look Like Across Key Jurisdictions?
A digital-asset fund manager operating cross-border does not hold a single licence. It holds a stack of authorizations, registrations and exemptions that varies by the jurisdiction of the manager entity, the jurisdictions of the fund vehicles, and the jurisdictions where marketing occurs.
In the EU, the manager requires AIFM authorization from a national competent authority, plus – depending on activity – CASP authorization under MiCA from ESMA or the relevant NCA. In the United Kingdom, the FCA requires cryptoasset registration under the Money Laundering Regulations for relevant activities, in addition to any investment management authorization. In Singapore, the manager requires the appropriate MAS licence tier under the Payment Services Act if it handles digital payment tokens, plus a Capital Markets Services licence if it manages a collective investment scheme. In the Cayman Islands and BVI, the regulatory position of the manager outside those jurisdictions is what matters most – both regimes export lightly in terms of manager-level authorization, but the manager's home regulator applies in full.
The United States creates a separate analysis. A manager raising from US persons – even through offshore vehicles – must engage with SEC investment adviser registration analysis, CFTC registration if the fund trades commodity interests (which the CFTC regards most crypto assets to be), and FinCEN's money services business framework if the manager or fund conducts money transmission. The interaction of these federal regimes with state money-transmitter licensing at the NYDFS level adds further complexity for managers targeting New York-based allocators.
Operators we advise routinely encounter the practical consequence of this multi-layer stack: the licensing timeline for a fully authorized cross-border fund manager, aggregated across jurisdictions, is longer than any single jurisdiction's stated process time suggests. Planning should account for this at the outset.

What Are the AML and Travel Rule Obligations for a Digital-Asset Fund?
A digital-asset AIF and its manager carry AML/CFT obligations that go beyond what equity fund managers typically encounter, because the assets themselves move on-chain and create transaction-level data trails that regulators now expect to be monitored and reported.
The baseline is the FATF Recommendations, and specifically Recommendation 15, which subjects virtual asset service providers to the same AML/CFT standards as traditional financial institutions. The Travel Rule – the obligation to pass originator and beneficiary identifying information with a virtual asset transfer above the applicable threshold – applies in virtually every jurisdiction that has implemented FATF standards. The threshold varies by jurisdiction and the applicable regime; the BVI VASP Act 2022, the Cayman VASP Act, the MAS Payment Services Act and MiCA each implement the Travel Rule with nuances in threshold, scope and technical standards.
For a digital-asset fund, the Travel Rule creates operational obligations at the transfer layer. When the fund moves assets between its own wallets and exchange accounts, between counterparty custodians, or in connection with subscriptions and redemptions paid in crypto, the manager or its service providers must pass the required data. Most institutional-grade crypto custodians have Travel Rule compliance tooling, but the manager must verify that the full transfer chain – including any sub-custodian or DeFi protocol interaction – is covered.
AML program requirements for the fund itself – investor KYC, source-of-funds verification, ongoing monitoring, SAR/STR filing obligations – are set by the regulator of the fund vehicle and, separately, by the regulator of the manager. Where these are in different jurisdictions, the more demanding standard typically governs in practice, because institutional investors and prime brokers apply their own AML due diligence and will not invest in a fund whose AML program they regard as deficient.
How Is Custody Arranged for a Digital-Asset AIF?
Custody is the most operationally differentiated aspect of a digital-asset AIF compared to a traditional fund, and it is also the area where board-level oversight obligations are highest.
For EU funds subject to the AIFMD framework, the depositary obligation is the central structural challenge. A regulated depositary must hold fund assets or oversee the custody function. For traditional assets, this is standard market practice. For crypto assets held on-chain, the depositary must either directly custody the keys – which most regulated depositaries do not currently do – or appoint a regulated sub-custodian that does. The sub-custodian must itself be a regulated entity in a jurisdiction whose regulatory perimeter the depositary is satisfied with. This chain of delegation is workable but narrows the field of viable providers materially.
Outside the AIFMD framework – Cayman, BVI, Singapore structures where the depositary obligation does not apply in the same form – the fund's custodian is typically a regulated digital-asset custodian holding a licence from VARA, the FSRA, MAS, the FCA or an equivalent regulator. The key parameters the board must assess are: whether the custodian segregates assets at the wallet level per fund, whether the insurance coverage extends to on-chain loss events (key theft, smart-contract failure), and whether the custodian's operational procedures satisfy the due-diligence requirements of the fund's target institutional investors.
Stablecoin positions within the fund add a further layer. Tether (USDT) and Circle (USDC) hold contract-level freeze and blacklist authority over their issued tokens, and issuers act on court orders or law-enforcement designations. A fund holding material stablecoin positions should have board-level awareness of this risk and a governance protocol for responding to an unexpected freeze event.
Decision Matrix: Which Profile Should Pick Which Structure?
There is no universally optimal AIF structure for digital assets. The right instrument depends on four decision axes: investor domicile and type, asset composition, manager location and licensing capacity, and time-to-market pressure.
Profile A – Institutional manager, EU investor base, mixed liquid/illiquid crypto portfolio. The optimal structure is a Luxembourg SCSp with an authorized AIFM (third-party platform or internally authorized). MiCA CASP analysis is required in parallel. Timeline to operational is extended relative to offshore vehicles. Key risk: depositary bottleneck for on-chain assets.
Profile B – Emerging manager, US and Asian family office base, liquid token strategy. The Cayman exempted limited partnership with a separate Cayman or BVI GP is the dominant choice. The manager must assess its home-jurisdiction licensing position and engage with CFTC commodity-pool operator analysis if US persons are included. Timeline to operational is typically shorter than an EU structure. Key risk: evolving CIMA perimeter under the VASP Act.
Profile C – Asia-Pacific focused manager, institutional and HNWI base, token and venture mix. The Singapore VCC offers strong institutional credibility and MAS regulatory clarity, at the cost of a MAS licensing requirement for the manager. A Cayman master with a Singapore feeder is a common hybrid. Timeline depends on MAS licensing queue. Key risk: DPT licensing scope for the venture-stage positions.
Profile D – Crypto-native operator adding a fund vehicle to an existing exchange or custody business. Structure follows the existing regulatory perimeter of the operator. If the operator holds a VARA licence in Dubai, a fund vehicle within the VARA regime is the path of least resistance. The board must assess whether the fund activity falls within the existing licence scope or requires a new activity authorization. Key risk: regulatory perimeter mismatch between exchange and fund activity.
Common Structural Mistakes Boards Make – and the Objection Handler
A common assumption is that any established offshore vehicle works equally well for a digital-asset fund. In practice, this is false, and the consequences of proceeding on that assumption are material.
The first mistake is treating domicile selection as a cost minimization exercise. A vehicle in a lower-cost offshore center may be perfectly adequate for a small, GP-driven venture fund. It is typically inadequate for a fund targeting European insurance capital, US endowments or sovereign wealth funds, all of which impose their own jurisdictional eligibility requirements at the AML and regulatory level.
The second mistake is deferring the manager-licensing analysis until after the fund structure is set. The manager's licensing position in its home jurisdiction constrains which fund domiciles are viable, which investor categories are accessible, and which marketing methods are lawful. Reversing the sequence – fund structure first, manager licensing second – creates structural incompatibilities that are expensive to resolve.
The third mistake is under-specifying the custody and depositary arrangement at the term-sheet stage. We have seen funds that reached a near-final term sheet with anchor investors before discovering that the fund's proposed custodian was not acceptable to the lead investor's own AML framework. At that stage, changing the custodian is possible but disruptive. The better practice is to confirm the custody architecture as part of the pre-launch structuring work.
A micro-matter illustrates the cost of the third mistake. In a recent structuring engagement, a digital-asset fund manager had selected a Cayman vehicle and a non-regulated custodian before approaching OBOLUS. The anchor institutional investor – a European insurance group – required a regulated depositary acceptable under its own internal investment policy. We identified two viable regulated sub-custodian structures, negotiated the delegated custody arrangement, and the fund closed on schedule. The added lead time was measured in weeks, not months, because the issue was surfaced early. Had it appeared at the legal-completion stage, the fund's launch timeline would have been set back materially.
How Should the Board Think About Cross-Border Tax Interaction?
Tax efficiency for a digital-asset AIF is a function of domicile, investor type, and the character of income the fund generates. Each variable interacts with the others, and the board cannot optimize any one in isolation.
At the fund-vehicle level, the relevant questions are whether the vehicle is tax-transparent (passing income and gains to investors in their own fiscal hands, as is typical for a Cayman limited partnership) or tax-opaque (subject to local tax at the vehicle level, as may apply to a corporate fund structure). Most institutional-grade digital-asset funds use transparent vehicles precisely to avoid double taxation – once at the fund level and again at the investor level.
At the investor level, the tax treatment of crypto-asset income and gains is jurisdiction-specific and, in many jurisdictions, still unsettled. Staking rewards, airdrop income, token-swap gains and DeFi yield all raise characterization questions that national revenue authorities are addressing at different speeds. A fund that generates material income from these sources must be structured so that the relevant characterization analysis is manageable for the investor's own tax reporting – which requires the fund administrator to produce detailed allocation schedules, not merely a single net-asset-value figure.
The cross-border dimension is particularly acute where the fund manager is in one jurisdiction, the fund vehicle is in another, and the investors are in a third and fourth. Each jurisdiction's controlled-foreign-corporation rules, transfer-pricing requirements and treaty-eligibility analysis must be considered in light of the others. In our practice, we work alongside allied counsel in the relevant jurisdictions to map this interaction before the fund structure is finalized.

FAQ
Where should a crypto fund be domiciled?
Domicile is determined by the intersection of three factors: the investor base (which jurisdictions they can access, and which AML standards they impose on their own subscriptions), the manager's existing licensing position, and the asset composition of the fund. Cayman and BVI structures suit broad investor access; Luxembourg and Ireland suit EU passporting; Singapore suits Asia-Pacific institutional capital. There is no universally optimal answer – the wrong choice creates tax leakage and restricts investor access in ways that are difficult to reverse post-launch.
Does a digital-asset fund manager need a licence?
In almost every material jurisdiction, yes. In the EU, the manager requires AIFM authorization and potentially CASP authorization under MiCA. In the UK, FCA cryptoasset registration and investment management authorization apply. In Singapore, the MAS Payment Services Act and the Capital Markets Services regime both engage. In the United States, SEC investment adviser analysis, CFTC commodity-pool operator registration, and FinCEN obligations all apply depending on fund structure and investor base. The full licensing stack must be mapped before launch, not after.
How is custody arranged for a crypto fund?
Custody for a digital-asset AIF depends on the fund domicile and the applicable regulatory regime. EU funds subject to the AIFMD framework require a regulated depositary, which must either directly hold on-chain assets or appoint a regulated sub-custodian. Offshore structures – Cayman, BVI, Singapore – use regulated digital-asset custodians directly, selected on the basis of asset segregation, insurance coverage, and institutional investor due-diligence acceptability. The board should confirm the custody architecture as part of pre-launch structuring, not at the term-sheet stage.
