change address

[jubalix]

is it that the second address of N addresses that I have is the change address for all transactions.

so say I have addresses 1- 5

1 has 1BTC
2 has 0BTC
3 has 1 BTC
4 has 3BTC
5 has 2BTC

If I send from 5 1 btc to some other address afterwards I would have


1 has 1BTC
2 has 1 BTC
3 has 1 BTC
4 has 3BTC
5 has 0 BTC

Is that right?


then say I send 0.5 from 2 to 4

1 has 1BTC
2 has 0.5 BTC
3 has 1 BTC
4 has 3.5BTC
5 has 0 BTC

because 2 sends 0.5 to itself as it is the change address?


thanks in advance

The first one is correct.
For the second one I'm not entirely sure, but sending to yourself doesn't usually make sense (unless the address is in a different wallet).

Also, in both cases you are forgetting the fee (0.0001, I think...).

that is what I wanted to say just like now So I just quote.

so address 2 is always the change address?

I believe Jim has confirmed this before, but I don't remember where's the post.

Yes - that's right - the change always goes to the second address, if it is present.
If there is just one address in your wallet it uses that as the change address.
