About

coincenter is not just another random implementation of some exchanges' REST API, it also provides a higher abstraction of each platform specificities by providing workarounds for the ones not implementing some queries (for instance, withdrawal fees is rarely accessible with the public endpoint, but coincenter can handle their query for all exchanges, by using screen scraping techniques of external resources when needed).

Also, it takes the user by the hand for more complex queries, like trades and withdraws, working by default in synchronized mode until the operation is finished (withdraw will not finish until the funds are received and available at destination, trade will not finish until the opened order is either matched / canceled).

Technically speaking, this project is for C++ enthusiasts providing an alternative to other crypto exchanges clients often written in higher level languages. It is an illustration of the elegance and possibilities of modern C++ in an area where it is (sadly) barely chosen.

Of course, all suggestions to improve the project are welcome (should it be bug fixing, support of a new crypto exchange, feature addition / improvements
