Monero "Double Spend" ????

[MoneroDS?]

Hi Folks:

This BTCTalk account is a new one-off throwaway account login I made just for this post, for privacy purposes (hope that's okay)

Posting this here just 'cuz I don't know quite what to do and wanna ask the community for input.

A couple days ago I made a transfer of bitcoin into a MONERO wallet and didn't immediately check it, just trusting it would've gone thru okay.

But now, today, I go and look at that address via MyMonero wallet and it appears to have been deposited TWICE into that address!

The time stamp on TWO transactions is exactly the same minute and second.

But the transaction ID's ARE different!  And, going on a few days now both transactions seem to have STUCK and are considered valid (?).

So, what could have happened here?  It's not so much I'm happy to have gotten an extra 51 monero (thirty bucks whoopie) but it's more than a little bit troubling to see that something like this could happen?  If it's plus thirty bucks this time, could be some day MINUS thirty thousand dollars!!!???

Comments appreciated.

how should we talk about this if you dont tell us the transaction id's?
and no, we wont type it off some picture. copy paste it here

maybe the exchange made a mistake, maybe mymonero, maybe its just all bullshit. like this noone can tell

Yes please. The "identifying" info you left is easily enough to find those transactions, given a bit of motivation. Why make it annoying for us to take a look? Post the full IDs of the two txs in question in *text* form.

Needs more information, post the ids so we can actually look into this.

[MoneroDS?]

Okay guys... sorry, no problem, just this stuff still kinda new to me.

If the info's already accessible from just part of trans ID?

Well OK then.  Not meaning to be annoying LOL

So, here they are:



Transaction 1:
51 Monero

Transaction 2:
51 Monero

So... what's up?

What happened here??

Thanks.

What I was saying was that the info you left was enough to (almost certainly) uniquely identify your transactions, just that there exist no tools to search by partial match at the moment (thus requiring motivation).

Looking at the txs in question, it's clear they came from the same sender. Was this an exchange withdrawal? It looks like their systems screwed up somehow and send you your money twice. From the network's perspective, there was no double spend or anything of the sort.

Edit: I do hope you've not discovered another withdrawal exploit at Polo. That would be sad.

It has happened before, monero should roll back the chain and fix the problem before more double transactions

[MoneroDS?]

Not sure if I wanna say where it was from...
maybe wait and see IF the party in question sees this post and contacts me first?

Again it's not so much I wanna keep the free thirty bucks, LOL, but more-so I'm concerned if this might somehow damage Monero, or Monero's reputation... OR even damage this particular third-party's reputation, who sent it, IF they could be somehow exploited by it too?  I wouldn't want to do that, either, so kind of have to step lightly here maybe...

Really kind of strange, actually, since even THEY so far don't seem to have noticed anything went wrong?

Hmm.

Hmm.

I assure this has nothing to do with Monero, at least not the Monero *network* (it's possible some implementation somewhere is responsible).

There was no double spend. Someone sent you coins twice. So yes, I'd recommend caution (you could contact the party in question as well), but not for Monero's sake.

L.O.L.
