Digital-Asset Fund Structuring and Tokenisation: What Changes and What Does Not

Tokenisation can improve transferability and operational efficiency, but it does not remove the legal architecture of a fund. Investor eligibility, ownership records, transfer restrictions, valuation, anti-money laundering controls and governance still determine whether the structure works, whatever form the interest itself takes. The distinction that matters for a Cayman fund is between tokenising the fund interest itself and simply accepting crypto subscriptions or investing in digital assets, because these are three different design questions with different governance, administrator, custody and record-keeping requirements.

"Tokenisation changes how an interest is held and transferred. It does not change what a fund interest legally is, or the governance obligations that come with issuing one. A token that represents a share still needs a share register behind it, an administrator who can reconcile it, and a board that governs the fund it represents." David Lloyd, Chief Executive Officer at CV5 Capital

Executive Summary

A tokenised fund interest is still a fund interest, subject to the same investor eligibility, transfer restriction and governance requirements as a conventionally held share, with the technology layer determining how ownership is recorded and transferred rather than what obligations attach to holding it. Structuring a tokenised or digital-asset-focused fund correctly requires distinguishing three separate questions that are frequently conflated.

• Tokenising the fund interest, accepting crypto as a subscription currency, and investing the fund's assets in digital assets are three distinct design decisions, each with different structuring implications.
• A tokenised interest requires an authoritative register of record, and the token must be reconcilable to that register, not treated as a substitute for it.
• Investor eligibility and transfer restrictions apply to a tokenised interest exactly as they apply to a conventional share, and the technology needs to enforce, not bypass, those restrictions.
• Custody, valuation and audit evidence requirements for the fund's underlying digital assets are addressed separately from the question of whether the fund interest itself is tokenised.
• Anti-money laundering and know-your-customer obligations apply at the point of subscription and transfer regardless of whether the interest is represented by a token or a conventional share certificate.

Three Different Questions, One Recurring Conflation

The phrase digital asset fund is used to describe at least three structurally distinct propositions, and the governance requirements differ meaningfully between them. A fund that invests in Bitcoin, Ethereum or other digital assets but issues conventional shares to investors is, from a structuring perspective, a fund with an unconventional asset class, not a tokenised fund. A fund that accepts USDC, USDT or other digital assets as subscription currency, converting them to the fund's base currency or holding them directly, has introduced a subscription mechanics question distinct from either its investment strategy or its share structure. A fund that issues the investor's interest itself as an on-chain token, representing ownership of a share or unit, has introduced a genuinely different register and transfer mechanism.

Each of these can exist independently or in combination, and the governance, administrator and custody requirements differ accordingly. The mechanics of accepting digital subscription currencies are addressed in accepting USDC, USDT, BTC and ETH subscriptions: a fund operator's control framework, and the broader 2026 statutory framework for tokenised structures in Cayman is set out in the tokenised Cayman fund: the 2026 statutory framework.

The Register Question: What the Token Actually Represents

The central structuring question for a genuinely tokenised fund interest is what the token legally represents and how it relates to the fund's authoritative register of shareholders. Cayman company law requires a register of members, and a tokenised structure does not remove this requirement; it changes how that register is maintained and how ownership changes are reflected in it. The token itself should be understood as a representation of an interest recorded on an authoritative register, reconcilable to that register at any point, rather than as a self-standing record that exists independently of it.

The specific question of who maintains that register, and how a transfer agent function operates in a tokenised structure, is addressed in SEC transfer agent rules and tokenised funds: who maintains the register. The governance answer needs to be clear before launch: an administrator or transfer agent function that can reconcile on-chain activity to the fund's official register, rather than a structure in which the blockchain ledger and the fund's legal register can drift apart without a defined reconciliation process.

Investor Eligibility and Transfer Restrictions

A tokenised fund interest is still subject to the same investor eligibility requirements, whether under the Mutual Funds Act, the Private Funds Act, or the applicable offering restrictions, as a conventionally issued share. The technology does not create an exemption from investor qualification, minimum subscription requirements, or transfer restrictions designed to keep the fund within its regulatory registration category and its offering document's investor eligibility criteria.

This means the technical implementation needs to enforce these restrictions rather than merely record transfers after the fact. A tokenised structure that permits free peer-to-peer transfer of the token without a compliance check against investor eligibility and transfer restrictions at the point of transfer is not a workable design for a regulated fund interest, whatever its technical sophistication. Permissioned transfer mechanisms, whitelisting of eligible wallet addresses tied to verified investor identity, and an administrator function capable of approving or blocking a transfer before it settles are the practical requirements this creates.

Custody, Valuation and Audit Evidence for the Underlying Assets

Separately from whether the fund interest itself is tokenised, a fund investing in digital assets needs a custody, valuation and audit evidence framework for those underlying assets. These are addressed at length elsewhere and should not be conflated with the fund interest tokenisation question: custody arrangements determine who controls the private keys or exchange account credentials securing the fund's digital assets, valuation policy determines how those assets are priced for net asset value purposes, and audit evidence determines what documentation an auditor will accept as proof of the fund's holdings. The distinction between segregated portfolio ringfencing at the legal level and the practical custody arrangements that need to sit alongside it is addressed in segregated portfolio company ringfencing: does it survive crypto fund custody.

Anti-Money Laundering and Governance Do Not Change

Anti-money laundering and know-your-customer obligations apply at subscription and at transfer regardless of the technology used to represent the interest. A tokenised structure does not reduce these obligations, and in some respects increases the practical burden of discharging them, because a wallet address is not itself an identity and the fund's control framework needs to tie wallet addresses to verified investor identities with the same rigour applied to a conventionally onboarded investor. The board's governance role, including independent director oversight, valuation approval and the fund's overall accountability to CIMA, is unchanged by the choice to tokenise the interest; the board remains responsible for the fund regardless of how ownership is technically represented.

Building the Structure in the Right Order

The practical sequencing for a fund considering tokenisation is to resolve the underlying fund structure first, including its investor base, regulatory registration category and governance framework, and then determine which of the three design questions above the fund actually needs to answer with a tokenised or blockchain-based solution. A fund that begins with the technology and attempts to retrofit fund governance around it typically produces a structure that satisfies neither the technical ambition nor the regulatory and administrative requirements a Cayman fund needs to meet.

Key Takeaways

• Separate the three distinct questions: investing in digital assets, accepting digital subscription currencies, and tokenising the fund interest itself.
• Ensure a tokenised interest is reconcilable to an authoritative register of members, with a defined administrator or transfer agent function performing that reconciliation.
• Enforce investor eligibility and transfer restrictions technically, through permissioned transfer mechanisms, not only through documentation.
• Resolve custody, valuation and audit evidence for the fund's underlying digital assets as a separate workstream from the interest tokenisation question.
• Apply anti-money laundering and know-your-customer controls to wallet-based investors with the same rigour as conventionally onboarded investors.
• Structure the underlying fund and its governance first, then determine which elements genuinely benefit from tokenisation.

Frequently Asked Questions

Is a tokenised fund interest the same as accepting crypto subscriptions?

No. Accepting crypto subscriptions means investors can pay for a conventionally issued share using digital assets such as USDC or Bitcoin. A tokenised fund interest means the share or unit itself is represented as a token, which is a distinct structuring decision with different governance and transfer agent implications.

Does a tokenised fund still need a register of members?

Yes. Cayman company law requires an authoritative register of members, and a tokenised structure changes how that register is maintained and reconciled, not whether it is required. The token should be reconcilable to the register, not a substitute for it.

Can a tokenised fund interest be transferred freely, peer to peer?

No, not without compliance controls. A tokenised interest remains subject to the fund's investor eligibility criteria and transfer restrictions, and the technical implementation should enforce these through permissioned transfer mechanisms rather than allowing unrestricted transfer.

Does tokenisation change a fund's anti-money laundering obligations?

No. Anti-money laundering and know-your-customer obligations apply at subscription and transfer regardless of how the interest is represented, and a fund needs to tie wallet addresses to verified investor identity with the same rigour as conventional onboarding.

Who is responsible for governance in a tokenised fund structure?

The fund's board of directors remains fully responsible for governance, valuation approval and accountability to CIMA, regardless of whether the fund's interests are conventionally issued or tokenised.

What custody considerations apply to a fund investing in digital assets?

Custody of the fund's underlying digital assets is a separate question from interest tokenisation, covering who controls private keys or exchange account credentials, how those arrangements are documented, and what evidence an auditor will accept to verify the fund's holdings.
