There are not any particular relay coverage guidelines that apply to CPFP, as a result of in contrast to RBF, CPFP isn’t a relay coverage. It is a utterly regular new, further, transaction that will get relayed. The fee-bumping impact isn’t achieved by a particular relay mechanism, however by the miner’s block constructing mining logic recognizing the mix of kid and mum or dad as higher than the mum or dad alone.
For this to work, the block constructing code must be sufficiently highly effective to acknowledge this. That is the case if the miner instantly or not directly makes use of Bitcoin Core (model 0.13.0 or later).
Observe that there are common coverage guidelines that apply to dependant transactions (e.g. the ancestor and descendant depend limits, that are by default 25 transactions). They are not particular to CPFP, however might impression its use.
