Title: Armory have two incomming tx that I dont understand
Post by: varChar on August 10, 2014, 08:20:20 PM
I noticed today that I had two received addresses (the last two in my wallet) where one is on x btc and one is y btc, its only been one tx in each. The comment is [[ Change received ]] and if i open both of them have the same comments and it says the same as two outgoing transaction that I made those two dates and times.
If I look at my wallet transactions it doesn't have any received bitcoins at that size.

So I don't understand what happened.

You dont see change amounts. You only see how much was taken out of your balance, not how much was returned.

But the thing is that those two that I dont understand have an receiveing of two differents amount that isn't the same as the two to the outgoing site that I made a payment. The outgoing and incomming have the same time and date, but have different amounts.
And I shouldn't have any income from that site, and not more then I paid :)

Feels like it's a kinde of 'clean up' that armory does for organize the wallet..?

Say that 1 BTC was sent to your address A and you send 0.1 BTC to address B.
The whole 1 BTC has to be taken from address A ( that's how bitcoin works ).
So Armory sends in the same transaction the 0.1 to B and  (0.9 - fee) to a new change address C it creates for this purpose .

In this case there is a TxIn that redeems your 1BTC UTXO. A 0.9 UTXO is created on the change address. The net effect on your balance is -0.1 BTC, but the change address is oblivious to the spent amount, it only knows its new 0.9 UTXO.

Look at the funding transaction you say is different in amount. Double click on it and look at the change address and its funding, then compare that to your wallet address ledger.
