Principle 4 is the last of the four included in Section I of the Unidroit Principles on digital assets and private law. It discusses the purpose and definitions of the Principles. Principle 4 is dedicated to so-called linked assets, which are digital assets linked to another tangible or intangible asset and to which the Unidroit Principles also apply. However, the existence of the link, its requirements and effects, will be regulated by another law (a national law other than any national law that implements or is consistent with these Principles, in accordance with Principle 2 (2) and (3)).
