What is tokenization? Legal implications

The digitalization of assets is transforming how value is represented, transferred and managed. In this context, tokenization has emerged as one of the most significant developments within the blockchain ecosystem.

Despite its growing presence, the concept still generates confusion. It is frequently associated exclusively with cryptocurrencies, when in reality they represent only a specific application within a much broader phenomenon.

Understanding what tokenization means, the different types of tokens that exist and how they fit within the European regulatory framework has become essential for legal practitioners interacting with the digital economy.

Tokenization is not synonymous with cryptocurrencies

When blockchain is mentioned, many people immediately think of Bitcoin or financial speculation. However, cryptocurrencies are merely one specific application of a much wider technological development.

From both a legal and technological perspective, tokenization consists of digitally representing an asset, right, or utility through a token recorded on a blockchain network. In other words, tokenization converts an asset or right into a transferable and programmable digital unit.

The underlying asset may be virtually anything, including money, corporate shares, real estate, art, access rights to services, intellectual property or physical assets from the real world.

This leads to a key concept within today’s ecosystem: the tokenization of real-world assets.

Blockchain technology does not necessarily create new value. Instead, it digitizes the legal representation of existing value, enabling traceability, fractionalization and transfer without traditional intermediaries.

Cryptocurrencies, therefore, are not the origin of tokenization. They are simply tokens whose value derives from the digital economic systems in which they operate.

Difference between utility tokens, security tokens and NFTs

One of the most common misconceptions within the blockchain ecosystem is assuming that all tokens share the same legal nature. From a legal standpoint, however, token classification depends not on the technology used, but on its economic function and the rights it confers.

Consequently, the applicable legal regime is determined not by the fact that an asset is tokenized, but by what the token actually represents.

Regulation (EU) 2023/1114, known as MiCA Regulation (Markets in Crypto-Assets Regulation), establishes a harmonized regulatory framework for certain crypto-assets, introducing three main regulatory categories:

Asset-Referenced Tokens.
E-Money Tokens.
Other crypto-assets, a residual category in which utility tokens generally fall.

However, MiCA does not regulate the entirety of the tokenization phenomenon. The Regulation expressly recognizes that certain tokens, particularly those representing financial instruments, fall outside its scope.

In particular, security tokens, when they embody rights equivalent to transferable securities or financial instruments, remain subject to the traditional European financial markets framework, primarily MiFID II and the corresponding national legislation.

The legal conclusion is clear, the economic function of the token determines its legal regime.

Utility tokens: access, not investment

Utility tokens are defined under MiCA as crypto-assets other than asset-referenced tokens or e-money tokens.

These tokens grant access to a product or service within a digital ecosystem. They function as a digital mechanism of use or consumption, allowing holders to interact with platforms or benefit from specific functionalities.

Typical examples include:

Access to SaaS platforms.
Services within metaverse environments.
Tokenized loyalty or reward programs.

The determining element is that they do not grant financial participation rights or profit expectations. For this reason, they are generally not considered financial instruments.

The main legal challenges surrounding utility tokens typically relate to consumer protection, transparency obligations, contractual terms and technological compliance rather than financial regulation.

Security tokens: when a token becomes a financial instrument

Security tokens represent economic or financial rights linked to an underlying asset and perform functions equivalent to traditional financial instruments.

They may be equivalent to shares, holdings, debt, investment rights or even profit sharing.

From a legal perspective, blockchain technology is irrelevant for regulatory classification. If a token incorporates investment expectations or economic rights characteristic of transferable securities, financial markets regulation applies, including MiFID II, the Prospectus Regulation and supervision by national authorities such as the CNMV.

This reflects the principle of technological neutrality, whereby technology does not alter the legal nature of the asset.
A financial instrument remains a financial instrument, even when represented digitally on a decentralized infrastructure.

NFTs: digital uniqueness

NFTs (Non-Fungible Tokens) constitute a distinct category based on non-fungibility, meaning each token possesses unique characteristics and cannot be exchanged on a one-to-one basis with another.

They are commonly used to represent digital art, collectibles,gaming assets or digital certifications.

The regulatory focus tends to be on issues of intellectual property, usage licences, digital authenticity, and rights associated with the token vis-à-vis the asset represented.

A frequent misconception must be clarified: purchasing an NFT does not automatically transfer copyright ownership unless an explicit rights assignment exists.

Tokenization of Real-World Assets

Beyond purely digital environments, the true potential of blockchain technology lies in the tokenization of real-world assets, understood as the digital representation of traditional assets through tokens recorded on decentralized networks.

The underlying asset can be very diverse, ranging from real estate to shares, commodities or works of art.

Tokenisation allows for:
