How to start a crypto fund: the 2026 rules

By A. Bradley Randall, Founding Attorney · Published July 1, 2026 · Last updated July 1, 2026

“How do I start a crypto fund?” has become one of the most common questions we hear — and the answer got a lot clearer in 2026. A crypto fund is, at its core, a private investment fund: the same vehicle as a hedge fund, offered to the same kinds of investors, under the same securities exemptions. What's different is the engine — the digital assets it holds, the venues it trades, and the way it custodies and values them. That overlay is where the legal work is.

This guide walks the whole path in order, written for the manager who can run the strategy but hasn't built the fund around it.

Is a crypto fund even legal?

Yes. There are two questions hiding inside this one, and separating them removes most of the confusion. First, the fund's own interests are securities — so you offer them under a private-placement exemption, exactly as a hedge fund does. That part has never been in doubt. Second, the assets the fund trades are regulated too, and that's where the rules were unsettled until recently.

The picture changed in 2026. In a joint interpretation issued in March 2026, the SEC (the U.S. Securities and Exchange Commission) and CFTC (the U.S. Commodity Futures Trading Commission) took the position that most crypto assets are not themselves securities, and the agencies have shifted from regulation-by-enforcement to written guidance and coordination. For a fund manager, that means a far more workable environment than two years ago — though it's guidance, not statute, it does not carry the force of law, and it could be revised or withdrawn by either agency without notice. Pending legislation could also reshape parts of it.

Is your token a security or a commodity?

This is the question that drives your custody, your CFTC analysis, and your disclosures — so it's worth getting right. It's decided asset by asset under the Howey test (the legal standard from SEC v. W.J. Howey Co. for determining whether an instrument is an investment contract and thus a security). Bitcoin and Ether are treated as commodities; the SEC's 2026 guidance is that most crypto assets are not themselves securities. But two categories still are: tokenized securities (a security doesn't stop being one because it's on a blockchain), and tokens still tied to a promoter's ongoing managerial efforts. The practical step is to screen each intended holding before you build, because holding a security-token pulls in extra custody requirements, potential broker-dealer registration obligations, and restrictions on where and how those tokens can be traded — including the risk that transacting on unregistered platforms could violate federal securities law.

The structure — U.S. or cross-border

A crypto fund uses the same architecture as a hedge fund. For a U.S.-only raise, it's a single Delaware limited partnership (the fund), a general partner that manages it, and a management company — relying on Section 3(c)(1) (limiting beneficial owners to 100 accredited investors) or 3(c)(7) (allowing unlimited qualified purchasers) of the Investment Company Act. The manager runs the strategy (often, in a fund like this, with an algorithm) and deploys capital into exchanges and DeFi (decentralized finance) liquidity pools.

The moment you raise from non-U.S. or tax-exempt investors, you add an offshore layer: a Cayman feeder (and often a master), structured so that foreign investors can avoid U.S. tax filing obligations and tax-exempt investors can be shielded from UBTI (unrelated business taxable income) — though achieving these outcomes requires careful tax structuring and entity classification. That's the cross-border master-feeder, and it's the difference between our two crypto-fund tracks — a U.S. fund versus a cross-border build.

Raising the money — Regulation D

You raise the same way every private fund does: under Regulation D, either Rule 506(b) (a private, non-advertised raise from investors you know) or Rule 506(c) (you can advertise, but every investor must be verified accredited). You file a Form D (a notice of exempt offering filed with the SEC) and the state blue-sky notices. Whether you cap investors at 100 beneficial owners under 3(c)(1) (who will also need to be accredited investors under Regulation D) or open up to qualified purchasers (QPs) under Section 3(c)(7) is a structural choice — and for a crypto fund using derivatives, going 3(c)(7)/QP-only unlocks a useful CFTC exemption (below).

Do you register as an investment adviser?

The manager is an investment adviser, but registration isn't automatic, and it isn't uniform. Many emerging managers rely on the private fund adviser exemption and become an exempt reporting adviser (a lighter filing) rather than a fully registered adviser. Above the assets threshold you register with the SEC; below it, and without an exemption, you may need to register with one or more states — and state rules vary significantly (some states offer their own exemptions; others require notice filings even for exempt reporting advisers). The answer depends on your assets and where you and your investors sit, so it's confirmed as part of scoping the fund.

Do you register with the CFTC?

Only if you trade derivatives or use leverage. Non-security crypto are commodities, but spot trading generally isn't “commodity interest” activity under current CFTC interpretation, so a spot-only fund generally isn't a commodity pool today — though this position is unsettled and could change with pending legislation (see below). If you trade crypto futures, perpetuals (which are largely unavailable to U.S. persons on compliant exchanges and carry enforcement risk if accessed offshore), options, or on margin, the manager can be a commodity pool operator — and here recent relief matters: an adviser to a qualified-purchaser-only fund can avoid CPO registration by filing a notice, without the derivatives limits that constrain the older de minimis exemption. It's one more reason a derivatives strategy often points toward a Section 3(c)(7) structure.

Custody — the hardest part

For a fund that provides liquidity to DeFi pools, custody is the real design problem, because on-chain positions live in wallets and smart contracts, not at a traditional custodian — and assets deployed in a smart contract may fall outside qualified-custody protections entirely, exposing the fund to smart-contract exploit risk with no custodial recourse. The workable answer is a split: a qualified custodian for the idle sleeve (recent SEC guidance lets funds use certain state-chartered trust companies for crypto), and institutional multi-party-computation (MPC) custody for the on-chain sleeve — all supported by disciplined key management and an annual audit. Alongside custody sit two more must-haves: a written valuation policy for illiquid and DeFi positions (the single hardest operational issue), and AML (anti-money laundering) and sanctions screening of on-chain counterparties. A formal FinCEN (the U.S. Financial Crimes Enforcement Network) AML-program mandate for advisers is currently scheduled to take effect in 2028 (confirm the effective date, as it may change), but OFAC (the U.S. Office of Foreign Assets Control) sanctions apply now, and any serious fund screens from day one.
