IGNIS on Exchanges
Exchanges manage their own order books and balance sheets regardless of account balances on the Blockchain.
During the IGNIS airdrop on block 1636363 each exchange received 0.5 IGNIS per NXT into its Ardor account.
The distribution of IGNIS to exchanges may take few more days for the exchange to implement.
Therefore there is no need to open a ticket about this now, and especially not for Jelurida.
Our recommendation is to wait until Jan 5th and if you still don't see your IGNIS balance contact your exchange.
