Is there a list of double pay transactions somewhere?
I had most of my coins invested in shares and received a <1 BTC transaction that was my recent dividends from before the shutdown.
Even though it is a small amount I would like to return this if it was double payed, but I really have no clue what my balance was at shutdown.
If you had gotten a double payment then you would have gotten 2 transactions with the exact same amount. You sound like you got only one payment so you arent one of them.
