Trade up Contract Simulator for CS:GO

This app simulates Trade-up contract. User can choose any weapon from any tiers. One thing that makes us special is that we have all tiers, from consumer grade to covert. The main idea is to choose 10 weapons from the same tier, choose condition and add them into contract. If contract is full then you can sign it and recieve new gun. The new weapon is storable or you can sell it for money and see if you lose money or you make money. Also all weapon prices are real, taken from Steam market.
