Regulators across the leading fund domiciles are asking harder questions about digital-asset vehicles than they did three years ago. A sponsor who spent months structuring a fund only to discover that the chosen domicile cannot accommodate institutional allocators, that the administrator refuses to NAV a portfolio of illiquid tokens, or that the manager's home regulator requires a licence the team never sought – that sponsor has lost not just time but window. Crypto fund formation under heightened scrutiny demands that every decision – domicile, legal vehicle, manager authorisation, custody and banking – be made in sequence, with each leg supporting the others.
This page sets out the regulated basis for digital-asset fund structures, the practical formation process, the cross-border realities that change the analysis, and the common mistakes that cause capable managers to restart from scratch.
Why Regulatory Scrutiny Has Intensified for Crypto Funds
Regulators in every leading fund domicile now treat digital-asset vehicles as a distinct risk category, not merely as an alternative-asset variant. The shift is structural. MiCA at the EU level and the FSRA regime in Abu Dhabi have each introduced asset-specific requirements that ripple into fund documentation, custody arrangements and manager authorisation. The Cayman Islands Monetary Authority (CIMA) and the BVI Financial Services Commission (BVI FSC) have each updated their expectations for funds holding virtual assets. Ireland's Central Bank, as the competent authority for UCITS and AIFs, has issued supplementary guidance on digital-asset funds that goes beyond the baseline AIFMD regime. The cumulative effect: a fund that would have launched in twelve weeks in an earlier environment now takes considerably longer, and a structural error caught late in the process – the wrong legal vehicle, a custody arrangement the regulator will not accept, an investor class that triggers additional authorisation – can restart the clock entirely.
The most common trigger for delay is not regulatory hostility. It is sequencing. Managers who begin with the fund documents before confirming manager authorisation, or who choose a domicile before confirming which investor categories they intend to accept, regularly reach final review only to find a foundational mismatch. In our practice, we see this pattern repeatedly. It is correctable, but correction costs time the market does not always give back.

How Do You Choose the Right Domicile for a Crypto Fund?
Domicile selection is the first consequential decision in crypto fund formation, and it is the one most frequently made on the wrong basis. Choosing a jurisdiction because it is familiar, or because a prior non-digital-assets fund was domiciled there, routinely produces the wrong answer. The right question is: which domicile supports the full stack – the legal vehicle, the regulatory status of the manager, the investor universe, the custody provider, the administrator and the banking relationship – without structural conflict?
The leading options each carry distinct trade-offs.
The Cayman Islands remain the default for US-connected managers and for funds with a mixed institutional and sophisticated-individual investor base. CIMA's updated virtual asset fund framework imposes registration and operational requirements that are manageable for a well-prepared sponsor, and Cayman counsel infrastructure for crypto funds is mature. The domicile is, however, increasingly difficult to bank from and requires careful structuring for managers whose home regulator requires local presence.
Ireland, operating under the AIFMD regime with digital-asset overlay guidance from the Central Bank of Ireland, offers a regulated EU AIF structure that is passport-eligible. The Central Bank's expectations for crypto-specific risk disclosures, custody arrangements and valuation policies are demanding. Timeline and cost reflect that. For a manager seeking institutional European allocators – pension funds, insurance companies, fund-of-funds – the Irish AIF is often the only vehicle that will satisfy investor due diligence requirements. We advise on Ireland-domiciled crypto fund structures and the separate question of manager authorisation, covered below.
The BVI, under its VASP Act regime, and the AIFC in Kazakhstan, under the AFSA framework, serve different profiles. The BVI remains a fast, cost-effective structure for smaller vehicles and for feeder funds that sit beneath a master domiciled elsewhere. The AIFC is increasingly relevant for managers serving Central Asian and Gulf institutional capital, given its common-law structure and proximity to the VARA and FSRA ecosystems in the UAE.
Luxembourg's RAIF and SIF structures, and Singapore's VCC framework under MAS oversight, serve institutional managers with strong operational footprints in those hubs. Neither is a light-touch option. Both require manager authorisation, a depositary or approved custodian, and an administrator acceptable to the competent authority.
Does the Fund Manager Need a Licence?
Almost always, yes – and the failure to confirm this early is the single most expensive sequencing mistake in crypto fund formation. The manager authorisation question is distinct from, and prior to, the fund domicile question. A manager domiciled in the UK that manages an AIF for professional investors requires FCA authorisation under the applicable alternative investment manager regime. A manager operating from the UAE serving third-party capital requires VARA or FSRA authorisation depending on where it sits geographically. A manager that is only managing its own proprietary capital is in a different position, but that position is narrower than most assume.
The cross-border reality makes this more complex. A manager incorporated in one jurisdiction but operating – making investment decisions, giving instructions to a custodian, communicating with investors – from another jurisdiction may be subject to the regulatory regime of the second jurisdiction regardless of where it is incorporated. Regulators in the leading hubs are alert to this. The FCA and ESMA have each published expectations around substance requirements that are relevant here: the decision-making must occur where the authorisation sits, not at a remote affiliate or a de facto desk in a lower-cost location.
For managers below certain AUM thresholds, registered or exempt routes may be available in some domiciles. These are narrower in scope than full authorisation and carry their own conditions. Whether a manager qualifies for an exempt route, and what conditions attach to that route in the relevant jurisdiction, requires jurisdiction-specific analysis before the fund documents are drafted.
What Legal Vehicle and Documentation Does a Crypto Fund Require?
The legal vehicle – limited partnership, protected cell company, limited liability company, open-ended investment company – determines the fund's governance structure, its tax treatment, its investor rights on redemption, and the extent to which the structure accommodates the liquidity profile of the underlying digital assets. A vehicle designed for a liquid, publicly traded portfolio is structurally mismatched to a fund holding illiquid token positions, locked staking positions or early-stage protocol investments. That mismatch surfaces at the first redemption gate, not at formation, and by then it is expensive to resolve.
Fund documentation for a digital-asset vehicle must address several points that standard alternative-asset documentation leaves ambiguous or silent. These include: the definition of "digital assets" in scope; the valuation methodology for illiquid or thinly traded tokens; the custody arrangements and the contractual relationship between the fund, the prime broker or custodian, and any sub-custodians in the chain; the treatment of hard forks, airdrops and staking rewards as income or corpus; investor suitability and AML/KYC obligations at subscription; and the risk disclosures required under the applicable regime – including, for EU-marketed funds, the overlay from MiCA where the fund holds assets that would separately constitute crypto-asset service provision.
In our cross-border practice, we have seen fund documents drafted from a generic alternative-assets template that reached final regulatory review only to require substantial redrafting of the custody and valuation provisions. The structural work – matching vehicle to asset mix and liquidity profile – done before drafting begins avoids that cost.
How Are Custody and Banking Arranged for a Crypto Fund?
Custody is the operational pinch-point in crypto fund formation, and it is the area where regulatory expectations have tightened fastest. Most leading fund domiciles now expect the fund to identify, at the point of registration or authorisation, a custody provider that meets the regulator's requirements for segregation, safeguarding and reporting. In several regimes – Ireland's AIF framework is an example – a depositary appointment is mandatory, and the depositary must be willing to accept a digital-asset mandate. The number of depositaries that will do so, and the terms on which they will do it, constrains the universe of viable structures more than managers typically anticipate.
For funds not subject to a mandatory depositary regime, the custody question is still foundational. A qualified custodian that holds the fund's digital assets under a written custody agreement, with clearly defined obligations on key management, insurance and reporting, is a prerequisite for institutional capital in practice even where it is not a regulatory requirement in law. Investors conducting operational due diligence will require it. Auditors accepting the engagement will require confirmation of the custody arrangement before they can sign the financial statements.
Banking compounds the challenge. The fund entity, the management entity, and often the general partner or carried-interest vehicle each require banking relationships. Digital-asset funds face elevated scrutiny from correspondent and clearing banks, and the account-opening process for a newly formed vehicle is substantially longer and more document-intensive than for a conventional fund. The cross-border dimension adds another layer: a Cayman-domiciled fund with a UK-based manager and investors domiciled across the EU and Asia will encounter different banking requirements in each of those contexts.
In a recent structuring matter, a manager had formed a fund entity and appointed a custodian before confirming that any bank in the relevant jurisdiction would open an operating account for the structure. The custodian was willing to hold assets; no bank was willing to process fiat subscriptions. We restructured the banking approach – identifying a jurisdiction with a more receptive banking environment, amending the subscription mechanics and the custodian agreement to accommodate the new flow – and the fund launched, though later than planned. The lesson: confirm banking viability before the fund documents are executed.
If a prior application stalled or a banking relationship was refused, a second read can identify the structural reason and the route forward. Write to info@oboluslaw.com or message us at t.me/oboluslaw.
What Cross-Border Obligations Attach When Accepting Investors?
Every investor's domicile adds a regulatory layer to the fund's obligations. A fund that accepts US persons – even a single general partner who is a US citizen – triggers US federal securities law considerations that affect the fund's structure, its marketing approach and its ongoing reporting obligations. Accepting investors from EU member states may require compliance with the marketing provisions of the applicable alternative investment manager directive, even where the fund itself is domiciled outside the EU. Accepting investors from jurisdictions that maintain their own AML/KYC onboarding standards adds subscription-process requirements that must be reflected in the fund documents and the administrator's operating procedures.
The Travel Rule – the obligation to pass originator and beneficiary data with a digital-asset transfer, derived from FATF Recommendation 15 – applies to transfers into and out of the fund where those transfers pass through regulated intermediaries. The fund's AML/CFT policies must account for this at the custodian and administrator level. A fund that distributes income or returns capital by digital-asset transfer must ensure that the transfer mechanics comply with the Travel Rule requirements of both the sending and receiving jurisdiction. This is not a detail for the final documentation phase; it shapes the choice of custodian, administrator and transfer agent from the outset.
The investor-base question also determines which exemptions from registration or marketing restrictions are available and which are not. An institutional-only fund with a high subscription minimum and a closed marketing approach occupies a different regulatory position from one that accepts sophisticated individuals in multiple jurisdictions. The decision matrix below reflects that distinction.
Decision Matrix: Matching Structure to Operator Profile
No single structure fits every crypto fund sponsor. The right combination of domicile, vehicle, manager authorisation route and custody arrangement depends on four variables: the investor base (institutional versus sophisticated individual versus mixed), the asset mix (liquid tokens versus illiquid early-stage positions versus mixed), the manager's home jurisdiction, and the intended fund size and expected launch timeline.
Profile A – institutional manager, EU investor base, liquid token strategy: An Irish QIAIF structure under the AIFMD regime, with an AIFM authorised by the Central Bank of Ireland, a depositary appointment, and a custodian drawn from the small group willing to accept digital-asset mandates, is the default answer. Timeline is substantial – typically measured in months, not weeks – and cost reflects institutional-grade documentation. The benefit is a passport-eligible structure that institutional EU allocators will accept. Manager authorisation and depositary appointment are non-negotiable; attempts to shortcut either of these have consistently been the source of late-stage failure in our experience.
Profile B – smaller manager, mixed international investor base, mixed liquid and illiquid: A Cayman exempted limited partnership registered with CIMA under the virtual asset fund framework, with a custodian appointment and a banking relationship confirmed before launch, fits this profile. The structure is well-understood by service providers. The manager's home-jurisdiction authorisation question must be resolved separately. If the manager is UK-based, FCA authorisation or a relevant exemption applies. If UAE-based, VARA or FSRA analysis applies. The Cayman structure does not resolve the manager-jurisdiction question.
Profile C – manager serving Gulf and Central Asian institutional capital: An AIFC structure under the AFSA framework, with consideration given to whether a parallel Cayman or BVI feeder serves non-Gulf investors, is increasingly relevant. The AIFC's common-law framework and its proximity to the VARA and FSRA ecosystems make it a natural fit for managers whose investor base and deal flow are concentrated in that region. Capital, fees and timeline are, as with all the above, jurisdiction-specific and require current verification.
A common assumption in the market is that any offshore vehicle works equally well for a digital-asset fund. The reality is the opposite: the choice of domicile directly determines which investors will subscribe, which custodians will engage, and whether the manager needs separate authorisation. A structure chosen for speed or cost without regard to these downstream consequences routinely requires restructuring before a second close.
What Are the Most Common Formation Mistakes?
Drafting fund documents before confirming manager authorisation is the most frequent error. It produces documents that are well-drafted for a structure the manager cannot lawfully operate. The documents must then be redrafted once the authorisation question is resolved, at cost to both timeline and legal budget.
Selecting a domicile for speed without confirming that the domicile can accommodate the intended investor base is the second most common error. A BVI registered fund is fast to form. It is not accepted by many institutional EU allocators, and it does not resolve the manager's own licensing requirements in the manager's home jurisdiction.
Leaving custody to a later phase of the formation process is the third structural error. Regulators and institutional investors both expect the custody arrangement to be identified and documented at or before launch. A fund that launches without a confirmed custodian appointment – relying on an informal arrangement or a self-custody position – will face that issue at the first institutional due diligence review.
Treating AML/KYC as a subscription-form exercise rather than a structural design question is the fourth. The Travel Rule obligations, the investor suitability standards, and the anti-money-laundering policies required by the relevant regime must be reflected in the fund documents, the administrator's procedures and the custodian agreement. A post-launch retrofit of these provisions is disruptive and signals operational immaturity to incoming investors.
Finally: underestimating the banking timeline. For a new digital-asset fund entity, an account-opening process that might take two to four weeks for a conventional vehicle can take considerably longer. Starting that process in parallel with the formation work, not after it, is the correct sequencing.
Self-Assessment Checklist Before You Begin
Before engaging formation counsel, a manager can pressure-test readiness by working through the following sequence.
First: is the manager's home-jurisdiction authorisation confirmed, in progress, or still to be assessed? If not yet assessed, formation work should not begin in earnest. The authorisation requirement may change the domicile choice, the vehicle, and the documentation structure.
Second: is the investor universe defined? Specifically – US persons, EU retail, EU professional, non-EU institutional, sophisticated individuals? Each category brings its own compliance layer. The universe must be confirmed before the domicile decision is locked.
Third: has a custodian confirmed willingness to accept the mandate? Not a preliminary conversation – a written indication of willingness to engage on terms. This confirmation should precede the first draft of the fund documents.
Fourth: has a fund administrator with digital-asset NAV experience been identified and given a preliminary look at the asset mix? An administrator who has not previously handled a portfolio of illiquid tokens, staking positions and DeFi protocol exposures will require more lead time than the formation timeline typically allows.
Fifth: has the banking question been assessed – not just for the fund entity but for the management entity and any general partner or carried-interest vehicle? Confirming banking viability at this stage avoids the restructuring cost described in the micro-matter above.
A manager who can answer all five questions affirmatively is ready to begin formation in earnest. Most managers who approach us can answer two or three. That is not disqualifying; it defines the scope of the preliminary work.

FAQ
Where should a crypto fund be domiciled?
Domicile depends on the investor base, the asset mix, the manager's home jurisdiction, and the availability of qualified custodians and administrators in the relevant market. Cayman remains default for US-connected managers; Ireland suits institutional EU allocators under the AIFMD regime; BVI and the AIFC serve specific regional and size profiles. There is no universally correct answer – a domicile that is optimal for one investor universe can be disqualifying for another. The decision should follow manager authorisation confirmation, not precede it.
Does a digital-asset fund manager need a licence?
In most cases, yes. A manager making investment decisions for third-party capital in a digital-asset fund will require authorisation from the relevant regulator in its home jurisdiction – the FCA for UK-based managers, VARA or FSRA for UAE-based managers, MAS for Singapore-based managers, and so on. Exempt routes exist in some jurisdictions below certain AUM thresholds, but the conditions for those exemptions are narrower than commonly assumed. Manager authorisation must be confirmed before the fund structure is finalised.
How is custody arranged for a crypto fund?
Custody for a digital-asset fund requires a qualified custodian willing to hold the specific assets in the portfolio under a written agreement addressing key management, segregation, insurance and reporting. For funds domiciled in a mandatory depositary regime – such as an Irish AIFMD-regulated AIF – a depositary appointment is additionally required. The universe of depositaries and custodians willing to accept digital-asset mandates is more limited than for conventional assets. Custody arrangements should be confirmed at or before the launch of the fund, not post-formation.
