Ahhh... no, the exchanges themselves don't have an address - unless they are also a coin.
So, back to the handbag analogy, the handbag itself has no address - you have your account login to access it, but it isn't a "coin address".
I'm still not exactly sure what you wish to do - sounds like to transfer BLURT to Ionomy, then sell for BTC, transfer the BTC to Kraken, then sell for Monero XMR. Is that right?
You have an Ionomy account? In there you will see the deposit memo needed for BLURT.
You see, with graphene chains the whole "address" issue is clearer - coz there is no address (!!) - the wallet address is your username, so when you transfer to the account "ionomy" you must include the memo to tell their site to put the coins in your account, else it just goes to theirs! lol
Exchanges do this otherwise every trade will rack up network fees - so all trades are done internally, on their own ledger, and only transfers to and from the exchange have to go through the relevant blockchain.
So your "Kraken account" will have a username and login, but that in itself is NOT a coin-wallet.
eg your various cards in your physical wallet all have card numbers, but the wallet itself doesn't (not until they barcode everything!)
To be clear I know how to swap from hive to blurt. I have some bitcoin on ionomy which they gave me for my hive (I sold all of my hive). The bitcoin is on iononmy. I want to buy monero with those bitcoin or swap, don't care where I keep them just how to do it.
I still don't understand the difficulty.
go to Kraken, look at their BTC deposit page and you will find the BTC address and maybe a memo too.
Go back to Ionomy and send your BTC to the Kraken address and memo.
(Some exchanges with some coins generate unique addresses, hence no memo needed, but if the coins are pooled then u must incl the memo.)
OK this sounds like a plan I can work with. THANKYOOOOOOOO 😘
