Also, when I hover over the unconfirmed parent, it shows a fee rate of 0.00 sats/vB despite me paying the higher fee on the second consolidation.
CPFP only increases the "
effective fee" of the parent and children transactions, not necessarily increases the parent's fee rate.
You can only see that effective fee rate during creation of the CPFP transaction by hovering your mouse over "
[→ CPFP " near the fee rate.
Anyways, AFAIK 0.00sat/vB in Sparrow is only possible if the fee rate source is set to "
Server" and your selected server "
Bitcoin Core" is configured to relay 0sat/vB txns.
If it's the case (
not a typo), I'd suggest you to set to standard minimum because even though you're be able to relay such transactions, most of your peers and miners will just reject it.
