I have an ERC20 token exchange CEX running as a game.
I currently have a working orderbook system and users can buy and sell tokens.
Currently, all of the code to execute trades and order fills is in the front end JS, but this causes problems if the users browser crashes or multiple users make orders at the same time.
I need either the exchange contracts to me modified or a backend nodeJS server to receive and execute orders, and also queue orders for execution if multiple users execute at once.
The code is 90% working on the front end, so it may need just to be implemented on a separate nodejs server running in the background, with the addition of order queuing.
Happy to pay in crypto.
Or provide skype address and i will add you
