Sending a transaction isn't always the end of the story. Using the RBF and CPFP protocols, a developer can continue to control the transaction after it's been sent, to improve efficiency or to recover transactions that get stuck.

After working through this chapter, a developer will be able to:

   * Decide Whether RBF or CPFP Might Help a Transaction
   * Create Replacement Transaction Using RBF
   * Create New Transactions Using CPFP
   
Supporting objectives include the ability to:

   * Understand the Mempool
   * Understand the Difference Between RBF and CPFP
   * Plan for the Power of RBF
