Eventhough they are only in the stage of the pre ICO , the team of ESR wallet have been successfully made a partnership to some big company.
I believe this is their step of preparation for the flight of their project. i believe this will be a very good one and will be big hit in the crypto industry.
I think the developers of this project (ESR) really want to have a successful project in the future that's why they quickly gathered strong partners in the beginning to have an assurance. For me it's a great move for Devs., and it's good for investors, participants and for the users also because they are sure to the project they support.
