-snip- A friend of mine told me that Bitcoin has been sent to her wallet and since two today it fails to confirm, so can she make it to be confirm faster with application??
It depends if the wallet supports CPFP (
child-pays-for-parent)
Because if not, you'll have to find a way to spend the specific unconfirmed output and manually compute the necessary fee rate to bump the parent transaction.
So, what wallet is it?
Also, the transaction may have unconfirmed parent(s) with 'high size-low fee' as well that could render your CPFP attempt ineffective.
So knowing the txid can help us determine your chances and possible recommended additional fee.
