Replace-by-Fee (RBF) is a feature that enables Bitcoin users to replace their original transactions by paying a higher fee. In general, accepting RBF transactions comes with a higher risk of double spend attacks, as well as the risk of a user changing the amount of a transaction before it is mined. Due to these risks, we unfortunately cannot accept RBF transactions at this time.
