Second version of java multi-language blockchain exchange/fiat currency trading/coin-to-coin second contract/contract leverage exchange
This system is based on the source code and is available in multiple languages. It also adds a second contract function and repairs the K-line.
The source code comes with a complete installation tutorial, and the front end is vue source code.
The screenshots are from the exchange client. If you want to see the demonstration, don’t come. The JVAV pure source code demonstration is not something you can just do.
Note that the default background is the first picture. The background of the screenshot was changed to the Ruoyi framework by someone else (the open source framework can be changed by yourself)
