I sent balance of NEM to NEMwallet from POLONEX several hours ago.
At that time, as the following attention was displayed, I input the message which I thought about by oneself.
"You MUST send your deposit using the unique Message below. Failure to do so may result in the loss of your deposit."
However, I cannot receive NEM with an NEM wallet yet.
Will unique Message have other meanings?
What should I do?
All Polo deposits go into one huge account that everyone shares. You have to enter a message in your NEM transaction to tell them who you are (your random code).
When you take XEM from your regular wallet and send it to Poloniex, they need the unique message to know it is really you.
When you send XEM from your Poloniex account to your regular NEM wallet, it doesn’t need a unique message, just your address is fine.
Hello.
I appreciate your kind response!
Ummm…Sorry the message may not be the cause …
I cannot receive NEM with an NEM wallet yet.
I asked to support of POLONIEX about this.
They showed a record of the transaction in the following.
"http://chain.nem.ninja/#/search/,,,,,"
(Is it problem if I put a actual URL of transaction record here?)
The transaction looks like completed.
However, I do not receive NEM with the NEM wallet.
Also the transaction history of the NEMwallet does not have the record that received NEM.
I confirmed an address, but it was not wrong.
As the version of the wallet was not latest, I updated it today.
However, the problem is not yet settled.
What should I do?
Hello! Ah, I see!

I cannot receive NEM with an NEM wallet yet…
