ABSTRACT Immaterial objects in digital social networks. The "transactor object" as a new category of art. How is it possible to initiate and maintain close relationships with people with whom we had never been physically close? Can we really know the other through this mediation? What is the role of technological devices with which we communicate? And the role of immaterial objects we exchange? ¿Are these objects involved in digital relationships beyond the will of the sender? Can they be considered as another participant in them? What happens in transit? Will traces of this mediations remain in the devices used? Besides, can we consider these exchanges as transactions? The new information and communication technologies have penetrated in such a way in contemporary societies that mobile phones and personal computers, among other devices, often become a kind of prosthesis of its owners, a social, occupational and emotional prosthesis. Through them we produce and exchange texts, images, videos and other information with other subjects. The use -production, processing, circulation and consumption- of certain intangible objects within online social networks raises issues that few decades ago did not have the same relevance: a reformulation of the relationship between subject and object, in addition to economic reorganization that entails. We propose to call this objects as "transactor" objects: mediating objects through which communicative acts occur, and from which, incidentally, they do not go unscathed. Bear an intrinsic mobility, they are objects-in-transit, "objects of exchange" in two ways, as they are part of a transaction, -according to the economics use of the term- but also suffer and cause changes. Its ontological incompleteness induce instability and therefore movement. An incomplete object, clamped, is also a restless object. We use here the term transactor to name objects that possess potentially or temporarily, the quality of transport, modify and transmit with some autonomy and unpredictability one or more actions, of which they are part and constitute its changing ontology. Throughout this research we make a historical tracking of certain changes in the relationship between man and labor and the economy in order to contextualize the situation of digital objects in the early twenty-first century. We also emphasize ways of reading the changes from the perspective of contemporary art, through practices associated with the transaction, the proposition of new economic models and the testing of collective experiencies of economic management. We also performed a group-type experience, the "Ágora Nómada", which revolved around the production and exchange of immaterial objects as the only tool of emotional and social construction among participants. Finally we conducted a junction between some practices carried out on the web and the theoretical approaches discussed, from authors such as Michel Foucault, Bruno Latour, Mieke Bal, Karin Knorr Cetina and Sherry Turkle. A back and forth between practice and theory from the participant's role has been the main method of work, an experience of tracing, of immersion and reflection as actors and subjects involved in an intangible network of exchanging affections, work and sociality. Considering these objects as "transactors" invites us to rethink the distribution of roles between the actors of artistic practice.
