All questions about partnership proposals to representatives of e-commerce should be directed to chat Telegram.
I believe that the team itself should be busy finding partners from business companies. I haven't seen an advertising campaign to raise awareness for such participants.
The strategy of the project on questions of search of partners in technical documents is not specified. I think that this description would help us to deal with this issue.
The team pays little attention to its advertising. I think the Paypex team is directly negotiating with those e-commerce participants who can popularize the applications. It's a long process.
