{"content":"How RBF Works:\nWhen a transaction is first broadcast, it is marked as \"opt-in RBF\" if the sender sets the RBF=1 flag in the transaction.\nAs long as the original transaction remains unconfirmed, the sender can create a new transaction that spends the same inputs but with a higher fee.\nMiners will typically include the transaction with the higher fee, effectively \"replacing\" the original lower-fee transaction.","contentType":"text/plain"}
