Ledou Chain is a corporate virtual currency launched by Shenyang Jingshun Network Technology Co., Ltd., which is mainly used as a token for commodity trading, and is applied to the online shopping mall - Ledou Mall, which is developed by the company itself. It replaces the settlement function of the legal currency in the process of commodity trading, so that the payment system of our mall can be created with high degree of freedom, which can ultimately solve the fraud problem in the transaction process.
