Erstellen eines Online Stores

Hey, this project exists of two shops. A customer can buy virtual currency for real money in shop1. Only 10 different products for the different currency amount are sold. The customer can see in his „My Account“-section how many units of the virtual currency he owns. The customer can also cash out his virtual currency via PayPal or Bank Transfer. The cash out is only possible with an amount of 5 EUR/ USD. 100 units of the virtual currency equal 1.00 EUR/ USD. In shop2 the customer can buy virtual goods, from an external marketplace, for the virtual money that he bought in shop1. Only virtual goods from customers are sold in shop2. The solution of both shops acts as a trust instance between both sides. If a customer decides to sell a virtual good on shop2, he sets his selling price as a value of the virtual currency. Depending on this the share of 10% of shop2 is display and it is shown what the customer really earns with his sale. Afterwards he receives a trade offer from a trade bot in the external marketplace. When the customer accepts the offer of the trade bot the virtual good is displayed for sale in shop2 and the good is in the inventory of the trade bot. If the virtual good gets bought, the appropriate value of the virtual currency is transferred from the buyers account to the account of the seller. Afterwards the trade bot makes a trade offer to the buyer with his bought virtual good. Every virtual good stays in the inventory of the trade bot as long as it is purchased. A trade bot, written in C#, is available for free. It needs to be checked if adjustments on the trade bot need to be made. To ensure the identity and trade within the external marketplace an integration via an existing web API to shop2 needs to be done. I'm looking forward to hear from you. Br
