An established operator expanding into a managed fund structure faces a question that looks deceptively simple: which vehicle, domiciled where, regulated how? The answer determines which investors can subscribe, how much tax the structure bleeds at each layer, and whether the banking relationship survives first contact with a compliance team. Getting that answer wrong early is expensive – not because the documents cannot be redone, but because the wrong domicile locks in tax leakage and limits which investors you can accept before a single subscription agreement is signed.
An alternative investment fund (AIF) – a collective investment vehicle that pools capital and invests on a defined strategy, subject to fund-regulation regimes rather than retail product rules – is the instrument most established digital-asset operators now reach for when they move beyond proprietary trading into third-party capital management. The relevant regimes vary: the Alternative Investment Fund Managers Directive (AIFMD) governs EU-domiciled and EU-marketed AIFs; equivalent frameworks apply in the Cayman Islands under CIMA, in the BVI under the BVI FSC, and in jurisdictions such as Singapore under MAS. The choice is not purely structural. It is a licensing, tax and distribution question simultaneously. This page maps the decision for operators who are already running a business and are ready to raise external capital.
The sections below move from the regulated perimeter, through the domicile and structure decision, to the application process, the cross-border distribution angle, common mistakes and a decision matrix by operator profile.
What is the regulated perimeter for a digital-asset AIF?
A fund that pools third-party capital and allocates to digital assets is subject to fund regulation in virtually every major capital market – the asset class does not create an exemption from the fund-management regime. The operative question is which regime applies, and that turns on where the fund is domiciled, where the manager sits, and where investors are located.
Under the AIFMD regime, any fund that is not a UCITS product and that raises capital from investors in pursuit of a defined investment policy is an AIF. The manager of that fund – the alternative investment fund manager (AIFM) – requires authorisation or registration depending on assets under management. For digital-asset funds marketed into the EU, the AIFMD passporting system matters: an authorised AIFM in one EU member state may distribute across the bloc. Outside the EU, Cayman-domiciled closed-end funds typically register under the applicable CIMA regime; Singapore funds operate under the MAS licensing regime for fund managers.
The digital-asset overlay sits on top of the fund regime, not beside it. MiCA (the EU Markets in Crypto-Assets Regulation) and VARA in Dubai impose obligations on entities that hold, transfer or manage crypto assets as a business activity – and a fund manager executing trades on behalf of the fund can trigger those obligations independently of its AIFM status. Operators who have run an exchange or custody business will already understand the VASP perimeter; translating it to the fund context requires mapping each activity the manager performs against the activity licences in the chosen jurisdiction.
In our practice, we regularly advise operators who assumed the fund vehicle would sit cleanly outside the VASP perimeter because it holds assets on behalf of a single legal entity – the fund – rather than multiple natural persons. That analysis is more fact-sensitive than it appears, and regulators in several leading hubs have signalled increasing scrutiny of that boundary.

Which domicile is right for a digital-asset AIF?
Domicile selection for a digital-asset AIF is the highest-leverage decision in the structure, and the wrong answer is not always obvious at the term-sheet stage. Three axes drive it: the investor base, the asset mix, and the redemption and liquidity profile.
The Cayman Islands remain the default for institutional closed-end structures targeting US and non-EU institutional capital. CIMA registration is well understood by prime brokers and institutional investors; the legal infrastructure – exempted limited partnerships, segregated portfolio companies – is mature. For a fund that will allocate primarily to liquid tokens and needs frequent redemption windows, a Cayman open-ended fund registered under the applicable CIMA regime is a defensible starting point. The BVI offers a lighter-touch alternative for smaller structures; the BVI FSC administers the VASP Act 2022 alongside the fund registration regime, and we have seen operators use the BVI successfully where the investor base is concentrated and the manager has strong compliance infrastructure in place.
For managers targeting EU institutional allocators, the domicile question is more constrained. Distribution to EU professional investors at scale typically requires either an EU-domiciled AIF with a licensed AIFM, or reliance on national private placement regimes (NPPR) where they remain available. Luxembourg and Ireland remain the dominant EU AIF domicile choices for managers with genuine EU distribution ambitions. Malta under the MFSA is viable for smaller fund structures, particularly where the manager already holds a MiCA CASP authorisation and wants to consolidate the regulatory footprint.
Singapore under MAS has emerged as a credible fund domicile for managers with an Asia-Pacific distribution strategy. The MAS Variable Capital Company (VCC) structure has attracted a number of digital-asset managers; the licensing obligations for the fund manager sit under the Payment Services Act alongside any fund management licence requirements. The key constraint is that MAS licensing timelines can extend, and managers who begin fundraising before the licence is in hand risk breach of the regime.
A common assumption is that any offshore vehicle works equally well for a digital-asset fund. In our cross-border practice, that assumption collapses at the banking stage. A Cayman fund whose prime broker or administrator requires EU AIFMD compliance for certain investor categories, or whose custodian applies FATF Travel Rule obligations that the fund structure was not designed to accommodate, discovers the problem only after commitments are in hand. We structure domicile, banking and compliance as one mandate from the outset.
Does a digital-asset fund manager need a separate licence?
Yes – in most leading jurisdictions, managing a fund is a regulated activity that requires an authorisation or registration distinct from any VASP or exchange licence the operator already holds. The manager licence and the fund registration are separate instruments, and conflating them is one of the most consistent mistakes we see in early-stage structures.
Under the AIFMD regime, the AIFM must be authorised in its home EU member state before it manages or markets an AIF to EU investors. Below certain thresholds the manager may register rather than seek full authorisation, with reduced disclosure and reporting obligations – but the threshold test is applied to the aggregate assets under management across all funds managed, not per fund. A manager that starts below the threshold and scales quickly can cross into full-authorisation territory mid-raise.
In Singapore, a fund manager managing a fund that invests in digital payment tokens requires a licence from MAS under the Payment Services Act in addition to any fund management licence. The precise licensing pathway depends on whether the managed assets are capital markets products under Singapore law – a classification question that turns on the token's characteristics, not the manager's intent.
In Dubai, a manager operating in VARA's jurisdiction requires the relevant VARA activity licence for management services. The VARA licensing framework is activity-based: holding, trading and managing are separate licensed activities, and a manager who also provides custody to the fund may trigger a second licence category.
The cross-border reality is that an operator domiciled in one jurisdiction whose fund is registered in a second, whose investors sit in a third, and whose trading infrastructure runs in a fourth can face licensing obligations in each layer. We have seen well-resourced operators spend significant time and capital on fund formation only to discover that the manager entity was conducting regulated activity in a jurisdiction where it held no authorisation. Early mapping prevents that outcome.
How does the fund application and setup process work?
The fund application process for a digital-asset AIF involves five sequential workstreams that must be coordinated, not run in parallel without oversight: entity formation, manager licensing, fund registration, service-provider appointment and investor documentation.
Entity formation comes first. The manager entity – typically an LLC, limited company or equivalent – is incorporated in the chosen jurisdiction. For Cayman structures, the fund vehicle (often a segregated portfolio company or exempted limited partnership) is incorporated separately. For EU structures, the AIFM and the AIF are distinct legal persons, and the relationship between them must be documented in an investment management agreement that satisfies the relevant regulator's requirements.
Manager licensing follows. The application to the relevant regulator – CIMA, MAS, the MFSA, VARA or an EU NCA under the AIFMD – requires, at minimum: a detailed business plan, an investment strategy document, AML/CFT policies, a description of the risk management framework, and evidence that the manager's key personnel are fit and proper. For digital-asset AIFs, regulators increasingly expect a specific section on the custody arrangements for the fund's assets and on the manager's approach to on-chain risk and valuation.
Fund registration runs in parallel with manager licensing where the regulator permits it, but many jurisdictions require the manager licence to be in hand before the fund is registered. The fund's offering documents – typically a private placement memorandum (PPM), a subscription agreement and the fund's constitutional documents – must be finalised before registration and must comply with the applicable disclosure requirements.
Service-provider appointment covers the administrator, the auditor, the prime broker (where relevant) and, critically for digital assets, the custodian. Custody of digital assets is a regulated activity in most leading jurisdictions. The custodian must be licensed in the relevant jurisdiction, and the custody agreement must address the specific mechanics of digital-asset safeguarding – private key management, segregation of assets, the protocol for on-chain transactions initiated by the manager.
Investor documentation closes the process. Subscription documents must comply with the distribution rules in each jurisdiction from which capital is accepted. For US investors, Regulation D requirements apply. For EU investors, the AIFMD marketing notification process applies unless an exemption is available.
In a recent matter, a digital-asset manager had completed entity formation and instructed an administrator before engaging fund-regulation counsel. The custody arrangement the manager had agreed in principle was not available to a fund under the applicable regime – the proposed custodian was not licensed for the relevant asset categories. We restructured the custody approach and the fund's investment parameters before the PPM was finalised, avoiding a re-solicitation of investor commitments. Timing early-stage counsel engagement to precede service-provider commitments is the single most cost-effective decision a manager can make.
If a prior application stalled or a service-provider arrangement has fallen through, a second read can surface the structural reason and the route forward. Contact OBOLUS at info@oboluslaw.com. Map your options
How does cross-border distribution affect the AIF structure?
Distribution is where domicile choices made early in the process become expensive constraints, and it is the section of the structure that most operators underestimate at the outset. A fund that was optimised for one investor category – say, US-qualified purchasers via a Cayman vehicle – faces a different analysis entirely when a European family office or an Asian sovereign wealth fund expresses interest.
Under the AIFMD regime, marketing an AIF to EU professional investors requires either full AIFMD authorisation and a marketing notification (the EU passport) or reliance on national private placement regimes. Several EU member states have restricted or withdrawn their NPPR availability, meaning that a Cayman fund marketed in those markets without an EU-domiciled feeder or parallel fund is potentially in breach. The practical consequence is that managers who want genuine pan-European distribution typically need an EU master or feeder fund alongside their offshore vehicle.
For US investors, the analysis turns on whether they are accredited investors, qualified clients or qualified purchasers, and on whether the fund elects to register as an investment company. Most digital-asset AIFs targeting US institutional capital rely on the available exemptions from Investment Company Act registration; the conditions for those exemptions impose limits on the number and type of investors that apply across the entire fund structure, not per share class.
The Travel Rule (the obligation under FATF Recommendation 15 to pass originator and beneficiary information with a virtual-asset transfer) applies to transfers between the fund's custody accounts and any external wallet. A fund that subscribes in kind – accepting crypto assets rather than fiat at subscription – or that redeems in kind faces Travel Rule compliance obligations at each transfer point. The fund's administrator and custodian must have the technical infrastructure to comply; not all service providers in the digital-asset custody space have built that capability to the standard that a regulated AIF requires.
Banking for the fund is a parallel constraint. A Cayman fund whose manager is licensed in Singapore and whose investors include EU-resident entities may find that obtaining a fiat bank account for subscription proceeds requires a relationship with a bank that has credit appetite across all three jurisdictions. We regularly advise on banking strategy as part of the fund-structuring mandate, and we have seen that appetite vary significantly by bank, by jurisdiction and by asset mix.
What are the tax considerations for a digital-asset AIF?
Tax treatment at the fund level, the manager level and the investor level operates on three independent axes that must all be addressed in the structuring phase. A structure that achieves regulatory compliance but generates avoidable tax leakage at any layer has not been optimised.
At the fund level, the domicile determines whether the fund itself is subject to corporate tax on gains and income, and whether the jurisdiction has treaties that reduce withholding tax on dividends or interest received from portfolio companies. Most established fund domiciles for digital-asset AIFs – Cayman, BVI, Luxembourg (for a qualifying AIF) – offer fund-level tax neutrality or a light-touch tax regime, but the conditions for that treatment are specific and must be satisfied in the fund's documentation and operations.
At the manager level, the jurisdiction where the management company is taxed on its management fees and carried interest determines the after-tax economics for the principals. The interaction between the manager's tax residence, the fund's domicile and the location of the principal investment decision-makers is a transfer pricing and permanent establishment question that regulators and tax authorities are increasingly examining in the digital-asset context.
At the investor level, the tax treatment of returns from a digital-asset fund – whether distributions are characterised as capital gains, ordinary income or something else – is determined by the investor's home jurisdiction, not the fund's domicile. For a fund with a mixed investor base across multiple jurisdictions, the offering documents must be drafted with the tax characterisation of each investor class in mind, and the manager must understand the tax reporting obligations that arise in each investor jurisdiction.
VAT and GST treatment of management fees is an additional layer. Several jurisdictions have clarified that management fees charged in connection with digital-asset funds are subject to VAT or GST; others have not. Where the manager entity is in one jurisdiction and the fund is in another, the cross-border supply of services rules apply, and the analysis varies by jurisdiction pair.
What are the most common structuring mistakes in a digital-asset AIF?
The most consistent mistakes we see in digital-asset AIF structures are not exotic – they are the predictable consequences of moving too fast, relying on templates built for traditional assets, or treating the regulatory, tax and banking workstreams as separate problems.
The first mistake is choosing domicile before mapping the investor base. A manager who selects a Cayman vehicle because it is what they know, and then discovers that the majority of their committed capital is coming from EU investors who require an AIFMD-compliant vehicle, faces a restructuring exercise that costs time and credibility. Domicile selection must follow investor-base analysis, not precede it.
The second mistake is treating the custody question as a service-provider procurement exercise rather than a regulatory design question. In most leading jurisdictions, custody of digital assets for a fund is a regulated activity. The custodian must be licensed; the custody agreement must satisfy regulatory requirements; and the technical setup – key management, segregation, transaction authorisation – must be documented in the fund's offering materials. Operators who come from an exchange background sometimes assume that their existing custody infrastructure can serve the fund; the regulatory requirements for a fund custodian are typically more onerous than those for an exchange's own custody.
The third mistake is underestimating the timeline. A full AIFMD authorisation process in an EU member state takes materially longer than an offshore registration; a MAS fund management licence adds months to a Singapore structure; VARA licensing in Dubai is a multi-stage process. Managers who begin fundraising conversations before the manager licence is in hand risk conducting regulated activity without authorisation. The timeline must be built into the fundraising plan, not treated as a parallel track.
The fourth mistake is the banking gap. Digital-asset funds have encountered significant difficulty opening fiat bank accounts for subscription proceeds and management fee payments. A structure that is legally impeccable but unbankable is not a viable fund. Banking strategy – which institution, in which jurisdiction, for which account type – must be assessed during the structuring phase, with fallback options identified before the fund launches.
Which structure fits which operator profile?
The right structure for a digital-asset AIF depends on the operator's existing regulatory footprint, investor base, asset strategy and timeline. Three profiles illustrate the decision range.
An established exchange operator with a concentrated institutional investor base – primarily US-qualified purchasers and Asian family offices, no EU distribution intent – is typically best served by a Cayman exempted fund structure with a CIMA registration, a manager entity in a low-tax jurisdiction with credible regulatory standing, and a licensed digital-asset custodian. The timeline from inception to first close is primarily driven by the custodian due-diligence process and the investor subscription documentation. Key risk: banking for the management company, particularly if the operator's exchange business has had compliance friction with banks.
A manager with an existing EU presence – perhaps a MiCA CASP authorisation in Luxembourg or Malta – who wants to raise from EU institutional investors at scale is positioned to use that regulatory footprint as the AIFM and domicile the AIF in the same jurisdiction. The passporting benefit under the AIFMD regime reduces the distribution compliance burden materially. Key risk: the AIFM authorisation process adds time and cost; the manager must satisfy the AIFMD's organisational requirements, including the appointment of a depositary, which is a separate regulated function from custody.
An operator building a hybrid strategy – liquid token allocation alongside early-stage protocol investment – who expects investors from multiple regions faces the most complex domicile decision. A master-feeder structure, with a Cayman master fund and an EU feeder for EU investors, is the most common solution; it adds structural cost but preserves distribution flexibility. Key risk: the complexity of operating two regulated vehicles simultaneously, with different reporting obligations, different audit timelines and different investor registers, requires a level of operational infrastructure that smaller managers sometimes underestimate at the outset.
In each profile, the intersection of the manager's existing compliance posture, the fund's asset mix and the investor base's regulatory expectations determines the answer. There is no single dominant structure.

FAQ
Where should a crypto fund be domiciled?
Domicile should follow investor base, asset strategy and distribution intent – not convention. Cayman suits US and Asian institutional capital in a closed-end structure. Luxembourg or Ireland suits managers with EU distribution ambitions under the AIFMD passport. Singapore under MAS suits Asia-Pacific strategies. The BVI is viable for smaller, concentrated structures. Tax treatment at the fund level, banking availability and custodian options in each domicile must all factor into the analysis before a decision is made.
Does a digital-asset fund manager need a licence?
Yes – in most leading jurisdictions, managing a collective investment vehicle is a regulated activity requiring a separate authorisation or registration, distinct from any VASP or exchange licence the operator already holds. The applicable regime depends on where the manager is incorporated, where it exercises investment discretion, and where investors are located. A manager operating across multiple jurisdictions may face licensing obligations in more than one. The manager licence must typically be in place before the fund is formally marketed to investors.
How is custody arranged for a crypto fund?
Custody of digital assets for a regulated AIF is a licensed activity in most leading jurisdictions. The fund custodian must be authorised in the relevant jurisdiction; the custody agreement must address private key management, asset segregation, transaction authorisation and the protocol for on-chain movements. The technical infrastructure required for a regulated fund custodian is more demanding than for an exchange's proprietary holdings. Managers should assess custodian availability and licensing status early – it is frequently a gating item for fund registration and for institutional investor due diligence.
