Just try sending the unconfirmed UTXO with a high fee. If it lets you, it supports CPFP.
Basically a miner will confirm both transactions to get the higher fee on the second transaction.
I don’t think moonpay supports CPFP they seem to be mostly a shitcoin exchange
Please Login to reply.
It is certainly worth a try
CPFP is done from the receiving wallet, not the sending wallet.
So no need for the exchange to allow it.
