Thanks Alex for your reply.
As I could search for this proposal, I would not need the licence if I use their service or another similar one. They have the licence and offer the service of white branding for other companies (b2b). So it would be only a matter of developping a new adapter (maybe an hybrid one for fiat and crpto if exists the service).
I understand that you are busy, but could you maybe considere it for a potential development in some near future?
Thanks again Alex
