We got a message from CoinExchange regarding a swap :
I have had very little time lately . We are upgrading the system at the moment. So unfortunately cannot commit to doing the swap at least for the next week.
Then we asked him if its ok to contact him after next week and he agreed.
In the meantime, I sent a query to Novaexchange with request to add Solaris with Xevan algorithm to their voting list .
Thank you for your support !
