<p>I got a stuck transaction and would like to clear this. I found many information about RBF (Replace-by-Fee) how it works etc. So i think this might be the best option to get my transaction going.  </p>

<p>Unfortunately i couldnt find any information about how to apply this command to the existing unconfirmed and zero-fee transaction. Please advise.  </p>

<p>THank you so much</p>

Unfortunately i couldnt find any information about how to apply this command to the existing unconfirmed and zero-fee transaction. Please advise.
