A fund manager building a digital-asset vehicle faces a decision that shapes every downstream outcome: where the structure sits, who can invest, and whether the chosen vehicle survives regulatory contact. The wrong domicile locks in tax leakage, restricts the investor base, and creates friction with custodians and prime brokers before the first capital call is made. GP/LP structuring for digital-asset funds is not a filing exercise – it is a cross-border legal architecture problem that sits at the intersection of fund law, crypto-asset regulation, tax treaty access, and AML compliance. This analysis maps the key decision points, the contrasting positions between leading domiciles, and the structuring logic a general counsel or fund sponsor needs before committing to a vehicle.
Why Domicile Is the First Strategic Decision – Not an Administrative One
The choice of fund domicile determines which investors you can legally accept, which regulators you answer to, and what tax position your limited partners inherit. For a digital-asset fund, the stakes are higher than for a conventional alternatives vehicle. Crypto-specific regulatory regimes add a second layer of authorisation risk that sits on top of the standard funds law analysis. A Cayman exempted limited partnership governed by CIMA under the Virtual Asset (Service Providers) Act reaches a different investor universe than a BVI limited partnership registered under the BVI FSC's VASP Act 2022, even though both are offshore common-law vehicles with broadly comparable structural features.
In our practice, we regularly see sponsors choose a domicile for historical reasons – "we've always used Cayman" – without mapping that choice against the actual investor base, the token types the fund will hold, and the custody providers that will accept the mandate. That mismatch surfaces late, usually during investor onboarding or at the first institutional due-diligence questionnaire.
The cross-border reality compounds this. A fund domiciled in the Cayman Islands but managed from London is subject to FCA financial-promotion rules and potentially to UK marketing restrictions. The same fund distributed into the EU triggers MiCA's third-country CASP provisions and potentially the relevant national private-placement regimes. A fund manager operating from Dubai sits under the VARA regime if the activity is conducted onshore in Dubai, or under the ADGM's FSRA framework if the manager is based in the Abu Dhabi Global Market. The entity, the manager, and the distribution channel each attract their own regulatory logic.
The domicile decision is, in effect, a jurisdiction matrix exercise – mapping the fund's legal home against the manager's operating location, the investor jurisdictions, the custodian's location, and the assets being held. Any one of those variables, taken alone, gives the wrong answer.
The process above describes the standard path. Your facts – the entity, the user base, the banking – change the analysis significantly. For a scoped assessment of your domicile options, contact OBOLUS at info@oboluslaw.com.
How Does a GP/LP Structure Work for a Digital-Asset Fund?
A GP/LP structure (general partner / limited partner structure) separates management control from economic participation: the general partner manages the fund, assumes unlimited liability for its acts, and earns carry; limited partners contribute capital, receive returns, and enjoy liability limited to their commitment. For a digital-asset fund, this architecture is attractive because it maps cleanly onto the on-chain custody and governance logic – the GP controls the signing keys (or the custodian mandate), while LPs hold economic interests in the partnership's net asset value.
The vehicle itself is most commonly structured as an exempted limited partnership in the Cayman Islands, a limited partnership in the BVI, or – for managers seeking a regulated onshore profile – a limited partnership or fund vehicle within a regulated centre such as the ADGM or the AIFC. Each carries a different regulatory footprint, a different investor eligibility profile, and a different tax treatment of carried interest.
Several structural choices arise immediately on forming the vehicle. First, whether the fund is open-ended (permitting redemptions on a defined cycle) or closed-ended (capital locked until a defined harvest period) has a direct bearing on the custody model. A fund holding illiquid token positions or early-stage protocol tokens cannot support weekly redemptions without significant liquidity risk. Second, whether the GP entity needs its own licence. In most regulated jurisdictions, the entity that manages a fund – making investment decisions, exercising discretion – requires authorisation as an investment manager or equivalent, separate from the registration of the fund itself. Third, whether a feeder structure is needed to segregate different investor categories – US persons, non-US persons, tax-exempt investors – each of which may require distinct legal wrappers sitting above or alongside the master fund.
In our cross-border practice, the single most common structural gap we identify is a GP entity that holds itself out as the fund manager without having mapped whether that activity, in the jurisdiction where the principals sit, requires a licence. The answer varies sharply by location: managing a fund from Singapore engages the MAS licensing regime under the Payment Services Act and the relevant capital-markets services framework; managing from Dubai implicates VARA's activity-based licence categories; managing from the UK engages FCA authorisation thresholds.
Which Domiciles Compete for Digital-Asset Fund Business?
Five jurisdictions dominate the current market for digital-asset fund formation, each with a distinct regulatory logic, investor-access profile, and cost of compliance.
The Cayman Islands remains the default for institutional digital-asset funds. Under CIMA, a fund holding digital assets may register as a registered person or seek a VASP licence depending on the activities conducted. The exempted limited partnership structure is well understood by prime brokers, institutional LPs, and custodians. Cayman's lack of direct taxation is an advantage for cross-border investor bases, and the VASP Act provides a dedicated registration pathway for fund vehicles engaging in virtual-asset activities. The principal risk for Cayman structures is increasing scrutiny from EU and US investors around substance, tax transparency, and FATF greylist risk – the latter of which has historically affected specific Cayman sub-sectors and requires ongoing monitoring.
The BVI offers a faster, lower-cost registration path under the BVI FSC's VASP Act 2022. BVI limited partnerships are commonly used for smaller or emerging-manager vehicles and for single-family office structures. BVI is competitive on speed and cost. It carries a similar investor-access profile to Cayman but has historically been viewed as a tier below Cayman for institutional acceptance.
The ADGM in Abu Dhabi gives a manager a regulated onshore profile within a common-law free zone, with the FSRA as regulator. The ADGM's approach to digital assets under the FSRA framework is explicit and relatively well-developed. For a manager seeking a Middle Eastern investor base or a regulated identity for marketing purposes, the ADGM offers material advantages over an offshore vehicle – at a higher cost and with more demanding authorisation requirements.
The AIFC in Kazakhstan is an emerging alternative for managers targeting the CIS investor base or seeking a lower-cost regulated profile. AFSA has an explicit digital-asset regime. The AIFC offers a common-law environment and an independent court system. It is not yet at institutional depth parity with Cayman or the ADGM, but it is growing.
EU-domiciled structures – Luxembourg SCSp or Irish QIF – give access to the EU investor base under AIFMD (the Alternative Investment Fund Managers Directive) passporting. For a digital-asset fund, the MiCA layer adds complexity: the fund's activities may bring the manager or the vehicle within the scope of CASP authorisation under MiCA as well as AIFMD. EU-domiciled structures carry the highest compliance cost but offer the broadest institutional investor access in Europe without reliance on national private-placement regimes.
Decision Matrix: Which Fund Profile Fits Which Vehicle?
Selecting the right vehicle requires mapping the fund sponsor's profile against five decision variables: investor base geography, asset class mix, liquidity profile, manager operating jurisdiction, and cost tolerance.
Profile A – Emerging manager, seed stage, non-US non-EU investor base, liquid tokens. The appropriate vehicle is typically a Cayman exempted limited partnership with CIMA registration, potentially a BVI partnership as a lower-cost variant. The GP entity is a Cayman or BVI exempted company. The custodian mandate goes to an established digital-asset custodian with Cayman experience. Timeline to first close is a matter of weeks from engagement, depending on CIMA processing. Key risk: insufficient institutional investor acceptability if the fund scales and seeks larger LPs later.
Profile B – Mid-market manager, institutional LP targets including European pension allocators, mixed asset class (liquid tokens plus SAFT/early-stage protocol positions). A Cayman master fund with EU and non-EU feeders, managed by a licensed AIFM (for the EU feeder) and a Cayman GP (for the offshore feeder), is the standard architecture. The AIFM can be a third-party ManCo or an internally licensed entity in Luxembourg or Ireland. The MiCA CASP question needs to be assessed separately for the management entity. Key risk: complexity and cost of running parallel regulatory regimes. Timeline is materially longer than a pure offshore structure.
Profile C – Manager based in Dubai or Abu Dhabi, targeting GCC institutional capital, holding a mix of digital assets and tokenised real-world assets. An ADGM-domiciled fund under the FSRA framework, with the GP entity holding an FSRA licence, gives the investor base regulatory familiarity and the manager a credible regulated identity. For distribution into mainland Dubai, VARA's fund-management activity licence may also be required. Key risk: regulatory cost and the need to maintain a genuine presence in the ADGM. Timeline depends on FSRA processing, which varies by application complexity.
Profile D – Single-family office or proprietary vehicle, small LP count, closed-ended, illiquid token positions. A BVI or Cayman structure at minimal registration cost, with the GP as a related-party entity and a custodian mandate to a qualified provider, is proportionate. No institutional distribution channel means the AIFMD and MiCA CASP issues are unlikely to be triggered. Key risk: if the family office later brings in third-party capital, the vehicle may need to be restructured for regulatory compliance.
If a prior application stalled or an account was closed, a second-read assessment can surface the structural reason and the route forward. Write to OBOLUS at info@oboluslaw.com to map your options.
What Does the GP Entity Need to Operate Legally in Its Home Jurisdiction?
The GP entity – the management company that exercises discretion over the fund's assets – must be assessed for licence requirements in the jurisdiction where it operates, not merely where the fund is domiciled. This distinction is consistently misunderstood, and it is the most common compliance gap we identify in digital-asset fund structures.
A Cayman exempted company acting as GP of a Cayman fund is, in principle, operating in the Cayman Islands. But if the principals who make investment decisions sit in London, the FCA's threshold conditions for managing investments may be engaged. If they sit in Singapore, the MAS Payment Services Act framework and the capital-markets services licensing rules are potentially relevant. If they sit in Dubai, VARA's management-of-virtual-assets activity licence may apply. The location of the people making decisions is the operative fact, not the entity's registered address.
Within the EU, the AIFMD adds another layer. A non-EU manager marketing to EU professional investors above the AIFMD marketing thresholds must either appoint an EU AIFM, register under the AIFMD national private-placement regime of each target member state, or rely on the relevant reverse-solicitation carve-out (which is narrow and cannot be engineered). Under MiCA, if the GP entity provides crypto-asset services to third parties, CASP authorisation is a separate question that sits alongside the AIFMD analysis.
For managers operating in the UAE, the VARA regime in Dubai is activity-based: the question is what activities the entity conducts, not merely what it calls itself. Management of virtual assets, advisory services, and custody are treated as distinct regulated activities under VARA's rulebooks, each requiring its own licence. A manager conducting multiple activities needs multiple licences or a combined application. The ADGM/FSRA framework takes a similar approach.
The AML dimension adds a further compliance obligation that runs parallel to the licensing question. Across virtually every major fund jurisdiction, the GP entity is a regulated person for AML/CFT purposes. FATF Recommendation 15 on virtual assets and the Travel Rule (the obligation to pass originator and beneficiary data with a transfer) apply to virtual-asset service providers; whether a fund manager falls within the VASP definition in the relevant jurisdiction requires a fact-specific analysis of the fund's activities and the token types held.
How Does Custody Work for a Digital-Asset Fund?
Custody is the operational lynchpin of a digital-asset fund, and the custody model must be agreed before the fund structure is finalised. Most institutional-grade custodians have strong preferences about fund vehicle type, governing law, and the jurisdiction of the GP entity. Picking a vehicle the preferred custodian will not service is a structural error that is expensive to reverse.
Regulated custody – the holding of digital assets on behalf of clients by a licensed custodian – is an explicit regulated activity in most flagship regimes. Under MiCA, custody and administration of crypto-assets on behalf of clients is a CASP activity requiring authorisation. Under VARA, custody is a separately licensed activity. Under the BVI VASP Act 2022, custody is within the definition of virtual-asset service. The fund's custodian must hold the relevant licence in a jurisdiction that the fund's governing law and the LP's due-diligence standards will accept.
Within a GP/LP structure, the custody arrangement is documented in a custodian agreement between the fund (or the GP on behalf of the fund) and the custodian. The agreement specifies the asset types, the signing arrangements, the settlement mechanics, and – critically – the liability allocation for loss events. For a fund holding volatile or illiquid digital assets, the liability cap provisions in a standard custodian agreement warrant careful negotiation. Some custodians set absolute liability caps that are substantially lower than the value of assets under custody; others offer segregated custody structures with higher protection at higher cost.
For funds with both on-chain token positions and tokenised real-world assets, the custody model may need to be split: a qualified digital-asset custodian for the on-chain positions, and a traditional securities custodian for any tokenised instruments that fall within the securities definition in the relevant jurisdiction. Coordinating two custodian agreements with different liability regimes and settlement cycles is an under-appreciated operational complexity in mixed-asset digital-asset funds.
In a recent matter, a fund sponsor had structured a Cayman vehicle and reached first close before discovering that their preferred custodian would not accept the structure's governing documents without material amendments to the liability and segregation provisions. We assisted in renegotiating the custodian agreement and amending the LP agreement to reflect the revised custody model, allowing the fund to proceed. The matter resolved within a matter of weeks, but the delay had implications for the fund's deployment timeline.
What Are the Most Common Structural Errors in Digital-Asset Fund Formation?
Six errors recur across the digital-asset fund matters we advise on. None is exotic; all are avoidable with early legal input.
First: choosing a vehicle before assessing the investor base. A Cayman fund cannot accept US persons without either Regulation D / Regulation S compliance or a full SEC registration – neither of which is implicit in the Cayman structure. A vehicle marketed to EU institutional investors without an AIFMD-compliant route creates distribution risk that may not surface until a specific LP's compliance department reviews the documents.
Second: treating the GP entity as a passthrough. Sponsors sometimes form a GP entity in the same offshore jurisdiction as the fund, with minimal substance, and operate the fund from a different country. The regulatory reality is that the operating jurisdiction of the principals determines which local licences apply. An offshore GP with onshore management is a common source of unlicensed activity exposure.
Third: using a generic partnership agreement without digital-asset-specific provisions. Standard LP agreement precedents drafted for private-equity or hedge-fund use do not address on-chain custody mechanics, hard-fork treatment, protocol governance voting, staking income allocation, or the NAV calculation methodology for illiquid token positions. These gaps generate LP-GP disputes at the worst possible time – when a hard fork splits an asset or a protocol vote materially changes the value of a position.
Fourth: omitting AML/KYC mechanics from the fund documents. The GP's AML obligations run to the fund's LPs. The LP agreement and side letters must reflect the GP's rights and obligations to request AML documentation, to redeem or gate an LP who fails AML screening, and to report to authorities where required. This is not merely a compliance formality: it is a structural protection against the fund becoming an AML enforcement target.
Fifth: ignoring the tax position of the GP's carried interest. The tax treatment of carry in a digital-asset fund varies significantly by the GP entity's jurisdiction and the characterisation of the underlying assets. Carry derived from the disposal of tokens that are treated as capital assets in a given jurisdiction is taxed differently from carry on income-characterised positions such as staking rewards or lending income. Early structuring of the carry vehicle protects the GP principal's net return.
Sixth: deferring the custody model to post-launch. As noted above, custody arrangements must be aligned with the fund structure before the LP agreement is finalised. A custodian agreement that conflicts with the fund's constitutional documents creates a legal gap that is difficult to close once LPs have committed capital.
The Cross-Border Reality: Manager, Investor, and Asset in Three Different Places
A digital-asset fund's legal architecture rarely sits in a single jurisdiction. The GP entity is in one place, the fund vehicle in another, the LPs in a third, and the custodian in a fourth. Each of those locations contributes a layer of legal obligation that the overall structure must accommodate.
This multi-jurisdictional reality is the defining feature of digital-asset fund practice. In a recent cross-border matter, a fund sponsor with a management team in one jurisdiction, a Cayman fund vehicle, and a European LP base had structured its vehicle without a legal analysis of the distribution restrictions in the LP home jurisdictions. We identified that the fund's marketing materials, distributed via a Telegram channel accessible to EU residents, engaged the financial-promotion rules in multiple member states under the applicable national private-placement regimes, as well as the MiCA marketing provisions for crypto-asset services. A revised distribution protocol and an updated set of LP communications were implemented before any regulatory contact occurred.
The tax dimension of the cross-border reality is equally demanding. Most major fund domiciles impose no direct tax at the fund level for non-resident investors. But the LP's home jurisdiction determines how distributions, carry, and token disposals are taxed in the hands of the investor. A US taxable LP in a Cayman fund is subject to PFIC rules if the fund does not elect into the mark-to-market or QEF regime. A European LP in a Cayman fund may face look-through taxation if the fund is treated as fiscally transparent under the LP's home country rules. These issues do not disappear because the fund is offshore – they shift onto the LP and, by extension, onto the GP's investor relations and operational burden.
Banking is the final cross-border pressure point. Digital-asset funds face persistent difficulty in maintaining fiat banking for the fund vehicle, the GP entity, and the management company. The bank's risk appetite for digital-asset counterparties is jurisdiction-specific and institution-specific. Cayman and BVI funds frequently bank in the Channel Islands, Canada, or specific European jurisdictions whose banks have developed digital-asset client programmes. Failure to secure banking before the first close is a material operational risk. We map banking options as part of the domicile analysis, not as an afterthought.
A Common Assumption That Warrants Correction
A common assumption among fund sponsors entering the digital-asset space is that any established offshore vehicle works equally well for a digital-asset fund. The assumption conflates legal validity with operational fitness. A BVI or Cayman limited partnership is legally valid as a fund vehicle. It is not automatically operationally fit for a digital-asset strategy.
Operational fitness requires that the vehicle's constitutional documents address digital-asset-specific mechanics; that the GP entity is licensed in its operating jurisdiction for the relevant activities; that the custodian accepts the structure; that the investor base can legally invest through the vehicle; and that the distribution channel complies with the marketing rules in each LP's home jurisdiction. A generic offshore vehicle satisfies none of these requirements by default. Each requires affirmative legal work.
Operators we advise routinely encounter this issue when they seek to onboard an institutional LP and receive a due-diligence questionnaire that exposes structural gaps in documents drafted without digital-asset-specific guidance. Retrofitting a structure after LP commitments have been made is costly, time-consuming, and creates investor-relations risk. The better approach is a fit-for-purpose structure from formation.
We match domicile to investor base, asset mix, and redemption profile. That matching exercise is the core of what a digital-asset fund formation engagement at OBOLUS involves – not a template filing, but a cross-border legal architecture mapped to the specific facts of the manager and the fund.

FAQ
Where should a crypto fund be domiciled?
The right domicile depends on the investor base, the asset class, the manager's operating location, and the fund's distribution strategy. The Cayman Islands is the most common choice for institutional digital-asset funds, given its established fund law, CIMA regulation, and custodian acceptance. The BVI offers a lower-cost alternative. ADGM and the AIFC suit managers with a regulated onshore presence in the Gulf or Central Asia. EU structures are appropriate where broad access to European institutional investors is the priority. There is no single correct answer – the domicile must be matched to the fund's specific facts.
Does a digital-asset fund manager need a licence?
In almost every case, yes. The GP entity or management company that exercises investment discretion over the fund's assets requires authorisation in the jurisdiction where its principals operate. Managing funds from London engages the FCA regime; from Singapore, the MAS capital-markets and Payment Services Act frameworks; from Dubai, VARA's management-of-virtual-assets activity licence or the ADGM/FSRA framework. The fund's offshore domicile does not exempt the manager from local licensing requirements in its operating jurisdiction. AML registration typically runs in parallel as a separate obligation.
How is custody arranged for a crypto fund?
Custody for a digital-asset fund is arranged through a regulated custodian holding the relevant licence in an accepted jurisdiction. The custody model is documented in a custodian agreement negotiated alongside the fund's LP agreement, covering asset types, signing arrangements, settlement mechanics, and liability allocation. Institutional custodians have specific requirements around fund vehicle type and governing documents. For mixed portfolios holding both on-chain tokens and tokenised securities, split custody arrangements across two qualified providers are common. The custody model should be confirmed before the fund structure is finalised.
