A DAO without a legal wrapper is, in the eyes of most regulators and courts, an unlimited partnership. That means personal liability for anyone who participates in decisions. This guide covers the three ways to fix that: a trust, a foundation, or Wyoming's DUNA, and how to choose between them.

Why a DAO needs a legal wrapper at all

Two tests matter here.

The liability test. Without an entity, a DAO is legally invisible until something goes wrong, at which point courts have treated unincorporated groups of collaborators as general partnerships. Every participant becomes personally exposed to the group's debts and legal claims.

The "who do I call" test. Regulators, including the SEC, ask whether a token still depends on the "efforts of others," typically a founding team or company. If the answer is one identifiable group, the token looks like a security. If governance and legal control are genuinely distributed, it doesn't. In March 2026, the SEC and CFTC issued joint guidance formalizing this framework, and the current SEC chairman has stated publicly that ETH is not a security under this test.

Getting the legal wrapper right affects both outcomes at once.

Option 1: Trust or Foundation (the classic stack)

The traditional approach uses two entities.

The trust or foundation sits at the top. It holds no shareholders and, ideally, no named beneficiaries: instead, the class of token holders as a whole benefits. Its only purpose is to grow the network, not generate profit. Assets, including tokens, are pledged to it, and it can make grants to anyone helping the network grow.

The operating entity sits underneath, 100% controlled by the trust or foundation. This is the entity that actually hires people, signs contracts, and receives grants to cover its costs. A Delaware or Wyoming LLC works well here for non-US teams; a C-Corp if you're raising from traditional VCs alongside the trust or foundation.

Common jurisdictions: Cayman (Foundation Company, purpose-built for this), BVI, Panama, and for US-based structures, Nevada or Wyoming trusts.

Trade-off: two entities to maintain, two sets of filings, and the design only works if the founding team genuinely gives up residual control, no reserved power to change beneficiaries or replace protectors and guardians at will.

Option 2: The Wyoming DUNA

Wyoming's Decentralized Unincorporated Nonprofit Association Act, effective July 2024, created a single entity purpose-built for what the trust-plus-operating-entity stack was trying to achieve.

A DUNA gives a DAO:

Legal existence, so it can contract, own assets, sue and be sued.
Limited liability for members, removing the unincorporated-partnership exposure.
A defined tax treatment for the entity and its members.
No requirement to name individual beneficiaries. Token holders qualify as members as a class.
DAOs with 100 or more members can generally self-declare as a DUNA without a separate state filing, depending on structure.

Trade-off: the DUNA is a new entity type. Case law is thin compared to a Cayman Foundation or a century of US trust law. It is also Wyoming-specific, so projects wanting a non-US jurisdiction still need the trust or foundation route.

Choosing between them

Use the trust or foundation stack if: you want the deepest body of case law, you're not US-focused, or your project needs an offshore jurisdiction for optics or banking reasons.

Use a Wyoming DUNA if: you want one entity instead of two, you're comfortable with a US wrapper, and you want the fastest, most straightforward path to legal existence for a token holder community.

Many projects use both: a DUNA or foundation at the governance layer, with a separate operating entity underneath for teams, contractors, and vendor contracts.

Real examples

Otonomos has set up Wyoming DUNAs for live projects, not hypotheticals.

dEdu, a decentralized, non-profit education project, runs as a Wyoming DUNA: no shareholders, no traditional board, governed by its members.

EthSystems, founded by former Ethereum Foundation privacy leads, uses the same structure to organise its community and treasury.

What a legal wrapper does not fix

A DUNA or foundation solves the legal problem: liability, contracting ability, tax treatment. It does not automatically solve the power problem.

Governance concentration is a real, ongoing risk regardless of entity type. MakerDAO's 2020 concentration in its top 50 MKR holders led directly to an attempted governance attack on its 2025 successor, Sky, requiring an emergency centralized intervention to stop it. The legal wrapper did not cause that risk and does not remove it either: it only determines whether the people running the project are personally liable, and whether regulators view the token as a security.

Decentralization is a design choice enforced by governance mechanics (voting thresholds, timelocks, distributed multisigs), not a side effect of picking the right entity.

FAQs

Do I need a lawyer to set up a DUNA?
No law firm retainer is required. Otonomos handles the filing and structure end to end.

Can a DUNA issue tokens?
Yes, this is one of its primary use cases.

Is a DUNA the same as an LLC?
No. An LLC has members with ownership interests. A DUNA is a nonprofit association structure without traditional ownership, built specifically for community governance.

Does a DUNA replace the need for an operating entity?
Not always. Many projects still use a separate operating entity for hiring, contracting, and day-to-day operations, with the DUNA holding the treasury and governance layer.

What happens if our project doesn't reach 100 members?
Smaller or earlier-stage projects may need to file directly with the state rather than self-declaring. Talk to your Otonomos advisor about the right path for your stage.

Is Cayman or Wyoming better for a Web3 foundation?
