Where do I find my Blockchain wallet's change address? Six days ago, I sent some bitcoin and it hasn't been confirmed. In an attempt to execute a Child-pays-for-parent transaction, I used my mnemonic seed to derive addresses from my blockchain wallet(in order to access my private keys), but I can't seem to find the change address on the list of derived addresses. Where can I find it?
Go to https://iancoleman.io/bip39/ and download the page to use it offline (you should never enter private keys into a website).

Scroll down and choose the BIP 44 tab. In the text box next to "External / Internal", change the 0 to 1. You should then get all of your change addresses derived below.
