Hey oeleo

I just checked my Bitcoin Wallet app and I can't seem to find the bc1 address in my 'address book' but I did notice that after doing this deposit i've sent I'm left with exactly 747satoshi on my android btc wallet

So maybe that bc1 address is the wallet that I sent from?

This is kind of confusing for a noob like myself. will be using an RBF enabled android wallet in the future for sure!
