By the time an allocator reads a term sheet, the manager has already made the decision that matters most: where the fund is domiciled and what kind of vehicle it is. That choice, not the track record, decides who is legally responsible for the coins, what a depositary or custodian is required to do about them, whether staking or lending inside the fund is permitted at all, and how an investor gets out. This is not investment, legal or tax advice; it is a map of what the wrapper itself decides, so that the diligence questions land on the right document.

The domicile decides whether anyone is obliged to check the coins exist

Fund domicile is usually chosen for tax neutrality and investor familiarity. For digital-asset funds it also decides whether an independent third party is legally obliged to verify what the fund holds.

Cayman Islands vehicles, still the most common offshore wrapper, carry no general statutory custodian or depositary requirement for regulated mutual funds or private funds. The tokenised-fund legislation of 2026, the Mutual Funds (Amendment) Act 2026, the Private Funds (Amendment) Act 2026 and the Virtual Asset (Service Providers) (Amendment) Act 2026, all in force from 24 March 2026, left that position where it was. Tokenised fund interests stay inside the existing audit and registration regime, the issuance of digital equity tokens and digital investment tokens by tokenised funds is excluded from the virtual-asset service provider regime, and no additional custodian obligation is imposed on the token structure. A CIMA-regulated fund holding coins directly can rely on custody arrangements of the manager's own choosing, with no external check built into the fund's legal structure beyond the annual audit.

European Union vehicles work the other way round: the depositary is a mandatory, separately regulated party under the Alternative Investment Fund Managers Directive, and its obligations attach whatever the manager would prefer. Luxembourg is the instructive case, and its position has moved recently enough that an older memorandum may describe a rule that no longer applies. The CSSF's communiqué of 22 February 2024 allowed alternative investment funds to invest in virtual assets directly and indirectly on condition that units were marketed only to well-informed investors. Its crypto-assets FAQ for undertakings for collective investment, rewritten at version 7 on 4 February 2026 and carried to version 8 on 24 April 2026 on the regulator's own record, went considerably further. UCITS may now take indirect crypto exposure of up to 10% of net asset value, through transferable securities that embed no derivative. Alternative investment funds open to retail investors may hold up to 10% of net asset value, directly or indirectly. Funds restricted to well-informed investors are not held to that cap, and a manager going above it needs CSSF authorisation for the "Other-Other Fund-Crypto-assets" strategy.

On custody the same FAQ sets out two routes rather than one standard, and the difference is the whole question an allocator is asking. A depositary that intends to safekeep crypto-assets itself needs authorisation or notification as a crypto-asset service provider under the EU's Markets in Crypto-Assets Regulation, and must tell the CSSF before it takes such a mandate. A depositary that does not offer crypto custody instead refers the fund to a specialised provider, and it is that provider, not the depositary, which carries the restitution liability. Both are lawful. Only the fund's own documents say which one applies, and therefore who is answerable if the coins go missing.

Ireland has taken the most cautious European position and put a number on it. The Central Bank of Ireland's AIFMD Q&A, updated 4 April 2023, does not permit UCITS or retail alternative investment funds to hold crypto exposure. It permits indirect exposure inside a Qualifying Investor AIF, capped at 20% of net asset value for open-ended funds and 50% for closed-ended or limited-liquidity funds, and it is explicit that direct investment is not permitted until it is demonstrated to the Central Bank that a depositary can meet its obligations to provide custody or safekeeping for the assets. That is a regulator declining to let the wrapper exist in the form allocators might assume it takes elsewhere, pending a custody standard it has not yet accepted as met.

Switzerland sits closer to Ireland's caution than to Luxembourg's flexibility, and for a structural reason: its funds regime never turned on the AIFMD distinction between financial instruments and everything else. FINMA's Guidance 01/2026, published 12 January 2026, confirms that a Swiss collective investment scheme holding crypto-based assets directly must place them in safekeeping with a Swiss bank acting as custodian bank under Article 72 of the Collective Investment Schemes Act. Delegation to a third-party custodian is permitted under Article 73, but only where that custodian is subject to equivalent prudential supervision and the assets are excluded from its bankruptcy estate under the applicable foreign law; FINMA indicated that custodians regulated under MiCA in EU member states are likely to meet the equivalence test. It was also explicit that a Swiss sponsor or manager does not escape the rule by routing the same strategy through a foreign vehicle.

The United States has no fund-level depositary requirement of the AIFMD kind. A private fund organised as a Delaware limited partnership or LLC is not itself subject to a custody rule; the obligation sits with the investment adviser, under Investment Advisers Act Rule 206(4)-2, which requires client assets to be held by a qualified custodian, traditionally a bank, a registered broker-dealer or a futures commission merchant. On 30 September 2025 the staff of the SEC's Division of Investment Management issued a no-action letter allowing registered advisers and registered funds to treat certain state-chartered trust companies as banks for this purpose, subject to conditions covering the custodian's authorisation, its key-management and cybersecurity policies, its audited financials and internal control reports, and a written agreement barring it from lending or pledging the assets. A purpose-built crypto custody rule is not yet in place. The SEC sent one to the White House Office of Management and Budget on 25 August 2026; it still needs a Commission vote, publication as a proposal and a comment period of at least 60 days before anything can be adopted. An allocator into a US-adviser fund is relying on a decades-old rule plus a staff letter, not on a crypto custody standard written for the asset.

Liquidity terms and side pockets: where the token, not the strategy, sets the timeline

Standard hedge fund liquidity terms assume the manager can convert a position to cash inside the redemption notice period. Digital-asset funds frequently cannot, for reasons that sit in the asset rather than the market: a token subject to a vesting schedule from a private round, a position that is bonded or staked and therefore locked for a protocol-defined period, or a position on a venue that has itself gated withdrawals. The market response, used well beyond crypto but now doing more work inside it, is the side pocket: a segregated class or series holding the illiquid or hard-to-value position, walled off from the liquid book so that new subscribers are not diluted into it and departing investors are not forced to sell it at a depressed mark to fund a redemption, with each investor's participation fixed by their pro rata interest at the moment of designation. That is fund-structuring practice as described by Maples in March 2026, cited here as law-firm commentary rather than as a rule of any regulator. There is no statutory side-pocket regime; the terms are whatever the governing documents say.

Staking makes the liquidity question concrete, because lock-ups are neither fixed nor short. Ethereum's validator queues are the clearest illustration precisely because they swing. The exit queue peaked at roughly 2.67 million ETH in September 2025, after a security incident at a large staking operator pushed an entire validator fleet towards the door, and had collapsed to near zero by the first week of January 2026. The entry queue then went the other way: by 20 May 2026 about 3.5 million ETH was waiting to be activated, a queue of 62 days. A fund's move into or out of a staked position is hostage to network-level congestion that has nothing to do with the fund's own decisions, on a timeline the manager cannot forecast when a redemption notice is accepted. A liquidity term that assumes staked assets convert to cash on the same schedule as spot holdings is written for an asset the fund is not holding. The risk and reward of the staked position itself is a separate question, taken up in Proof of Talk's piece on institutional staking.

Staking and lending also reopen the custody question the domicile was meant to have settled. Coins in cold storage under a qualified custodian are not the same asset, operationally, as coins delegated to a validator or supplied to a lending protocol: the permission to stake or lend is frequently one the custodian must grant to the manager or a staking provider, which is functionally a partial withdrawal from custody for the duration. Whichever of the Luxembourg routes above a fund has taken, or whichever qualified custodian a US adviser has appointed, the allocator's question is the same: does the sign-off cover assets in a staked or lent state, or only assets sitting still?

In-kind subscriptions and valuation authority

Most digital-asset funds accept cash subscriptions. Some, particularly those built around a specific token or a pre-launch allocation, accept the token itself. An in-kind subscription raises two questions a cash subscription does not: who values the contributed token at the subscription date, since that sets both the units issued and the investor's cost basis, and what diligence is performed on the token's own transaction history before it is accepted, since a fund that takes in tainted coins inherits the taint. Neither question has a standard regulatory answer. Both are governed by the fund's subscription agreement and valuation policy, which is why they belong on the diligence list rather than being assumed.

Valuation authority is a governance question the wrapper answers differently by jurisdiction. A Cayman fund's valuation policy is a matter for its own offering documents rather than a digital-asset-specific rule. A Luxembourg AIFM's valuation function sits under Article 19 of AIFMD whatever the asset class, which requires the valuation either to be performed by an independent external valuer or to be functionally independent of portfolio management within the manager, with conflicts mitigated. What digital assets change is not the rule but the input: with no consolidated market price, the policy has to specify which venues count, how an unlisted position is priced, and who decides when the administrator's mark and the manager's mark disagree. Those mechanics are the subject of Proof of Talk's companion piece on fund administration and NAV, worth reading alongside this one rather than repeated here.

What the wrapper does not tell you

None of this substitutes for the diligence a manager's custody, key-management and counterparty arrangements demand in their own right, covered separately in Proof of Talk's piece on operational due diligence for digital-asset managers. The wrapper decides only the legal starting point: whether anyone outside the manager must verify that the coins exist, whether staking is contemplated by the governing documents, and how an investor's money gets back out if the token will not convert to cash on the promised notice. A term sheet silent on any of those points has not avoided the question. It has left the manager to answer it unilaterally when the moment arrives.

Diligence questions specific to the wrapper

  • Which entity is the depositary or custodian, under which country's rule, and does that rule require it to safekeep the assets, to verify ownership, or neither?
  • Where the depositary does not itself hold the crypto-assets, which provider carries the restitution liability, and is that written down?
  • Does the depositary's or custodian's sign-off extend to assets while staked, lent or bonded, or only to assets in cold storage?
  • Does the domicile impose an investor-eligibility gate or an exposure cap, such as Luxembourg's 10% retail ceiling and well-informed-investor route above it, or Ireland's qualifying-investor threshold, and does every investor in the fund actually clear it?
  • Is there a side-pocket mechanism in the governing documents, on what triggers may the manager use it, and what happens to the management and performance fee on assets moved into one?
  • What is the stated unbonding or unlock period for any staked or vested position, and does the redemption notice period match it?
  • Are in-kind subscriptions permitted, and if so, who values the contributed token and what diligence is performed on its transaction history before it is accepted?
  • Who has final authority when the administrator's valuation mark and the manager's mark diverge, and is that authority written into the valuation policy or only assumed?

Where a regime is still moving, that status matters as much as the rule. AIFMD II's transposition deadline passed on 16 April 2026 with several member states, including France, Italy and Spain, not yet fully transposed. The MiCA transitional window for crypto-asset service providers already operating before the rules applied ran to 1 July 2026, shorter in member states that chose to cut it. The SEC's crypto custody rulemaking was still at the Office of Management and Budget through September 2026, with no proposal published and no rule adopted. An allocator reading a fund's custody or depositary representation today is reading a snapshot of a framework that has not finished moving.
