What about @jooize just posts numbers? Contractor 1,2,3,n and payment in the amount of X to contractor n?
Apart from that: @woolly_sammoth, I think you are are probably more closely involved with dev costs in general. Those transactions of 8 to 9k USD during April and May, was there any service provided to Nu that you are aware of that could cost like 8 to 9k USD times 4 for two months? I mean, if all your work since November has been worth $9522,50, then what has been done for Nu that is worth 4 times as much within a time frame of two months?
Edit: The least @jooize can do is explain what kind of service was rendered in particular for the large payments of 8 to 9k USD from 2017-05-30 / 2017-05-16 / 2017-04-27 / 2017-04-26. If there is heavy development going on, then 8k USD is not that much money, although it is still quite significant. But there was no development going on and @sigmike and @woolly_sammoth already kindly disclosed how much they got. @jooize what about bringing at least some light into this?
