Let's say I broadcast a transaction tx0
signaling RBF replaceability. Later on, send another transaction tx1
that spends the same inputs of tx0
, but this time with higher fees.
In this case, tx0 is removed from mempool right? so what if then I try to send a child transaction tx0child
that forms a more profitable CPFP than tx1
alone? But without the context of removed parent (tx0
) this CPFP cannot work then, although it's more profitable?
