I've heard a lot about Confideal. https://medium.com/@confideal/why-will-confideal-ico-be-successful-ad293f09d7e1 Think you should try it because it's a unique smart contract creating environment powered by smart contracts constructor, cryptocurrency payments, and even a digital arbitration system to work out the right judgements on unclear matters related to smart contracts performance.
Thanks for your input, do they have a whitepaper? I would like to learn more if possible.
