Non-fungible tokens (NFTs) are transforming the commercialisation of digital art by establishing unique blockchain identifiers that ensure authenticity and certify subsequent transactions. However, the transfer of control over an NFT does not automatically include the transfer of the associated copyrights, thereby creating legal uncertainty as to what rights are actually acquired. This interdisciplinary project between engineering and law proposes the design of a smart contract, based on the ERC-721 standard, to manage the transfer of property rights linked to digital artworks represented as NFTs. The accompanying legal contract incorporates essential clauses covering the identification of the parties, a description of the artwork and its link to the token, pricing, royalties, and the terms of rights transfer. The proposal seeks to integrate blockchain technology with existing legal frameworks, offering an innovative solution that strengthens legal certainty in the transfer of copyright within digital environments.
