A security token is a blockchain token that represents a claim on profits, revenue, equity, or a managed return from the efforts of others. It meets the legal definition of a security in most jurisdictions and triggers the heaviest regime: prospectus duties, accredited-investor rules, and ongoing disclosure.
Regulators do not read whitepapers. They look at what buyers were told and who controls the returns, so the label on your site is worthless if the economics say security.
How it works
Holders buy a security token because they expect to profit from the ongoing efforts of the issuer or a third party. That expectation is the defining characteristic, and it is precisely what US securities law, EU financial instruments law, and most comparable regimes are built to regulate.
How it is calculated
The US tool is the Howey test, which asks four questions: Was there an investment of money, in a common enterprise, with an expectation of profits, derived from the efforts of others? A token that clears all four prongs is an investment contract and therefore a security, whatever the project calls it. The SEC's 2019 digital-asset framework applies Howey to token facts, and enforcement since then confirms that the utility-token label is no shield when the substance is a profit claim.
Why it matters
In the EU, MiCA does not govern security tokens. Crypto-assets that qualify as financial instruments under MiFID II fall outside MiCA and into the existing securities stack: prospectus rules, suitability checks, ongoing disclosure. Projects that genuinely belong here and embrace it gain institutional capital, legal certainty, and the right to distribute revenue to holders. The burden is real but navigable.
Common mistake
Landing in the security bucket by substance while claiming utility by label. That gap is the enforcement target. We map every token against Howey before any architecture decision is locked, and we brief counsel on the specific choices that move each prong, because some of them, particularly decentralization and functional launch before the token sale, can shift the analysis materially.
See MiCA Compliance for Token Designs for how this applies in practice.
