So can devs answer me, please? I must to provide docs (which ones) or no? I mean do the KYC?
Yes, you will need to do the KYC. There will be a "How To - KYC" guide released today in a couple of hours, so you can read all about it there. But you will need your ID, adress, etc.
I do hate the fact that projects use KYC. it's so bothersome, not to mention the security concerns.
