Requisitos para um sistema de contratos inteligentes dentro do whatsapp

Abstract

This study investigated the feasibility of simplifying agreement formalization through WhatsApp, aiming to understand users’ challenges during informal negotiations and propose essential features for an automated contract creation tool without intermediaries. The main contribution of this work is the proposal of a theoretical and conceptual model for a smart contract system integrated into the application, intended to democratize access to legal formalization, reduce bureaucracy, and enhance trust in digital transactions. The findings indicated that, although WhatsApp offers agility and practicality, the lack of formalization mechanisms and legal certainty represents a significant barrier. Features such as guided contract creation, electronic signatures, secure storage, and traceability of information were identified as crucial, emphasizing usability, accessibility, and legal validity. For future studies, it is recommended to implement and validate functional prototypes, expand the participant sample, and deepen the analysis of legal, ethical, and regulatory aspects related to smart contract use in messaging platforms.
