Ava thanks for this response. Just to make sure I'm understanding you correctly. If I emptied my wallet of all my bitcoin and sent it to a new address with no change because I emptied it, then the output would have to be 0 Because I only had one output (the new address)?

Yes. The `vout` always counts up starting at 0.

<p>If I sent myself bitcoin to a new address on a different hardware wallet and it was all of my funds with no change, is it normal for the utxo output or &quot;vout&quot; to be 0?</p>
<p>It is my understanding that if I was not sending all my bitcoin and receiving some back in my change address that output or vout would now be 1?</p>
<p>Am I understanding this correctly?</p>

What does a utxo output or vout of 0 mean?

(Asked by: username_0 on 2024-01-01)

If I sent myself bitcoin to a new address on a different hardware wallet and it was all of my funds with no change, is it normal for the utxo output or "vout" to be 0?

It is my understanding that if I was not sending all my bitcoin and receiving some back in my change address that output or vout would now be 1?

Am I understanding this correctly?

`vout` is simply the index of the output in the outputs list of a transaction. It is used to identify which output of a transaction is being spent.

If your transaction only has one output, then the only possible `vout` is 0.
