Way back (check this forum thread)..  metamorphin ,limxdev from bitcore team helped josh with this coin.. you can see it all in here as advertised (go back to the first post and then move forward and you'll see it all) In fact I think Limxdev was listed as the main developer originally. More recently (about 12 months ago or so.. they know better than me) Metamorphin and Limxdev have not been involved although I think limxdev may have made some small tweaks to help out Josh before he got too busy.

As mentioned Metamorphin tried to point out in the discord chat that they were no longer involved in the coin and it was wrong to associate this coin with their work on Bitsend and Bitcore and for that Metamorphin was banned from discord. (That is my understanding anyways)
