Yes, Edollar is not a copy-paste coin. Exchange has to change something to make it work.
There is a branch on github that implement rpc methods (like verify_address, get_total_balance ...) and wallet notification mechanism (notify incoming transaction, block generated ...) to support exchange and 3rd integration (https://github.com/edollar-project/edollar/tree/exchange-support)
Then It will be fine if one exchange declined listing. There is a lot of big and good exchange over there, Just wait for a little time ...
