In some implementations, a system may receive interaction data indicating an object and a user location associated with a user of a plurality of users. The system may identify a user-based storage site, of a plurality of user-based storage sites corresponding to at least a subset of the plurality of users, having an object list that includes the object. A particular user-based storage site, of the plurality of user-based storage sites, may have a storage site location associated with a corresponding user. The storage site location may be within a distance threshold of the user location. The system may transmit location data indicating the storage site location. The system may receive retrieval data indicating that the object has been retrieved from the user-based storage site. The system may update the object list of the user-based storage site.
