Was ist CPFP (child pays for parent)?
Unsticking a low-fee transaction by spending its output in a new, high-fee transaction, making the pair attractive together.
Miners evaluate packages, so a child transaction paying well above market can subsidise its parent. This works when you control an output of the stuck transaction — often the change output.
CPFP is the recipient-side answer to a stuck payment, where RBF is the sender-side one.
