Smart and sustainable city must meet six criteria according to Giffinger. This paper analyzes the probability of the city of Bouake becoming a smart and sustainable city in a context of informal trade dominance. The conduct of this study is based on conducting a survey to collect qualitative and quantitative data. An interview guide is administered to the various actors involved in urban and digital development. As for the investigation, it is directed at traders. From this it follows that informal trade is the main source of urban employment. While the practice of this activity generates a frantic production of garbage and the presence of traders created a real urban entropy. In addition, green spaces are becoming public markets, sites of international institutions, housing, etc. Moreover, the digital divide is characterized by the persistence of gray areas. This situation does not facilitate the appropriation of digital by populations and administrations.
