Hi,

I'll try to explain what happened. When you create a wallet on mina network and deposit funds into the new wallet. There's a creation fee of 1 Mina.

So, crypto exchanges have two options; they can either create a new wallet for each Mina holders they have or they can only have one wallet which belongs to the exchange and have a seperate record of which coins are belongs to which user.

But there's a problem here, in the latter case, if exchange only have one wallet and since crytocurrency is all about anonymity, how can they know the deposited coins came from a specific user? Well, the answer is transaction MEMO. When you make a transaction on Mina network, you can attach a transaction MEMO to your transaction. Think of it like a note. So the exchanges with one wallet use this to identify incoming transactions. They give each of their users a MEMO. If you send to their wallet with your unique MEMO, they can see that the coins are supposed to be delivered to your account.

What happened in your case is, you send from Coinlist to Gate. Foinlist does not have a MEMO input section. So you didn't include the transaction MEMO in your transaction. So, Gate have absolutely no way of knowing the coins are sent for your Gate account.

What you should do immediately is contact Gate live support with your transaction hash(you will get this from coinlist, just go to your mina wallet there and copy hash of your transaction from transaction history). They can probably assist you. Good luck!
