Conflicting Nonce in Mempool

Send 33K stacks from my Stacks wallet to an Exchange with memo as specified by the Exchange.

Then tried to send another 33K to the SAME address but using a different memo.

Apparently this exchange is using ONE address and directing it to my account based on the memo.

Here’s the question: The second transaction failed with a “Conflicting Nonce in Mempool” error.

WHY??? Is there something fundamental that prevents TWO transactions to the same wallet at the same time? I can’t imagine that – but a second transaction to the same address will NOT go through.

It seems like you send both transactions with the same nonce.
I suggest you read this info that explains how nonce work and why it’s important.
