You are still not thorough about this question in my opinion and I believe that this is not a big project, so it will be difficult for you to open a campaign for it which is most acceptable on the forum. Nonetheless, you can still find a way around it if you are clever enough. First, note that direct codes for personal gains might not be allowed on the forum even though some are still cleverly doing it and people look away.

You might first want to state what your crypto project is all about before I or other people can be able to put you through on the most clever way you can do it and that will not break the rules of the forum.
