What is a crypto white paper?

By PlatformCrypto.eu editorial team · Last checked on 20 October 2026

Short answer

A white paper is the document in which a project explains what its token is and how it works. Under MiCA it has also become a legal disclosure: anyone offering a crypto-asset to the public in the EU, or seeking admission to trading, must publish one with set contents and notify it to a supervisor.

The genre started with Bitcoin. In October 2008, a nine-page paper signed Satoshi Nakamoto described a payment system that needed no trusted intermediary. Thousands of projects followed with papers of their own, ranging from serious technical specifications to glossy sales brochures. For years, nobody checked what they claimed or who stood behind the claims.

What MiCA changed

For most crypto-assets other than stablecoins, the EU's crypto regulation now requires a white paper before a token is offered to the public or admitted to trading on a platform. Its contents are prescribed, including:

who the offeror or issuer is and who runs the project;
what the token is and which rights and obligations attach to it;
the underlying technology;
the risks, presented prominently;
information on the principal adverse impacts on climate and the environment.

Each white paper must carry a statement that no competent authority has approved it. Supervisors receive it by notification but do not vet the content in advance. If it is misleading, those who drew it up are liable for the damage. Stablecoins face stricter rules, with authorisation before issue; see our stablecoins page.

Where to find a white paper

ESMA, the EU securities regulator, publishes notified white papers in its interim register, listing who prepared each one, through which supervisor and when. For coins without an issuer, such as bitcoin, the white paper is often drawn up by an exchange or a specialist firm seeking admission to trading. Our coin pages note in their sources when a MiCA white paper exists, for example Algorand and Ethereum Classic.

How to read one critically

Start with the risk section. MiCA requires it, so it should be easy to find.
Check the author. Did the issuer write it, or a third party with limited inside knowledge?
Look at the token allocation. How much belongs to the team and early investors, and when does it unlock? What market cap is explains why that matters.
Be wary of promises. A MiCA white paper must not suggest guaranteed value. A project that offers to sell you tokens with no white paper at all, or with return claims, is a red flag; if you have already lost money, see crypto stolen: what can you do.

Does a white paper say anything about the price?

No. It is a disclosure, not a quality mark and not advice. A token with a tidy white paper can still lose most of its value. How smart contracts behind many tokens work is explained in what a smart contract is.
