Of course we are 100% sure, XCI is an OPEN SOURCE public project. Everyone are free to contribute. We are in active cooperation with other cryptonote developers with great reputation - @slb from forknote and @aiwe from karbowanec. You are more than welcome to audit the source code and build your own binaries.
