Is there any way to move the old coins from Cryptopia? I have been away for a month or so and just realized that a coinswap had taken place but my old XLR coins are still on Cryptopia

The swap has not ended, so you have
two options. The first one, sell your old XLR, then buying the new one (with xevan algorithm). Secondly, send your old coins to the address for swap. How to swap the old coin is guided in the OP of the announcement.
Solaris with Nist5 algorithm is no longer on exchange.
You need to swap your coins manually through our swap system .
Here you have ours unique automatic swap website : https://solaris.swapyourcoins.today
1. Enter your "new Solaris" address
2. Send your "old Nist5 Solaris" to the given address
3. Receive the exact amount of "new Solaris"
"New address " you will find in your new Solaris wallet .
New wallet for Solaris with Xevan algorithm you can download from :
