Fee Bumping
Transactions● Common
Increasing the effective fee of an unconfirmed transaction to speed confirmation. Methods include Replace-By-Fee (RBF) creating a new version, and Child-Pays-For-Parent (CPFP) adding high-fee child transaction.
Technical Notes
RBF: BIP-125, replaces tx with higher-fee version. CPFP: child tx pays enough to cover parent. When to use: RBF if you're sender and signaled opt-in; CPFP if receiver or no RBF signal. Combined strategies possible.
