Ardor (ARDR, Nxt asset ID 12422608354438203866) will be upgrading from their Nxt blockchain asset to their dedicated Ardor blockchain.
The Ardor Genesis Snapshot will take place on the Nxt blockchain and it is scheduled for December 28th, 2017. The block height of the snapshot is 1636363. The new Ardor blockchain will become operational at 12:00 AM UTC, on 1/1/2018.
Users' Ardor Bittrex exchange balance totals will reflect the same total that they had prior to the swap in a 1:1 manner. The old Ardor tokens will no longer be supported or be traded on Bittrex.
Bittrex will re-enable trading Ardor tokens (ARDR) when we and the Ardor team agree that the migration is satisfactory and the blockchain network deemed stable.
Note: Bittrex will be closing our ARDR wallet to deposits and withdrawals. Bittrex will stop trading the ARDR token to take accurate snapshots of balances around block 1636363. If any ARDR deposits you had sent to Bittrex are not settled (i.e. marked as pending) by 6:00 PM PT, on 12/27/2017 (2:00 AM on 12/28/2017 UTC), you may not be credited with ARDR.
We would like to thank the Ardor team for working closely with us.
