Hi there, thanks for your feedback. 
Just like the previous contest held by illy on our platform, the Client has decided not to reveal the cash amount involved in the collaboration contract. The previous winner was contacted directly by the Client once the contest was over and the collaboration contract was concluded between the two parties alone. We can just confirm you that the total amount involved in the contract was in line with the market prices.
With regards to IP of the submitted projects, the authors will always remain the acknowledged authors of their works. If you want to learn more about it and other related matters, we suggest you to login on Desall.com and go to the Upload page of the contest at issue: there you will find the Contest Agreement with all details.
If you have any further doubts, you can also contact us to our e-mail address hello*[AT]desall[DOT]*com
