Blockchain transaction stuck
The fee market in Bitcoin can be very dynamic, with the fee-rate required for a transaction to be included in a block increasing or decreasing rapidly. One of the reasons for the volatility in the fee-rate is that the mechanism used to select what to include in a block is a market. However, there is one scenario in which the inability to withdraw a transaction from the mempool can become a serious problem for users: when the user has not attached a high enough fee-rate for the transaction to be confirmed in a block, and the user has an urgent need for the transaction to be confirmed. This could happen for many reasons: the wallet or user has underestimated how much fee is required, the user has tried to save fees by bidding at the low end of the fee estimation range, or the required fee rate has just spiked unexpectedly after the transaction was broadcast. We therefore need a method to bump up the fee on an already broadcast transaction for a couple of reasons:. The user constructs and signs a replacement transaction which spends one or more of the same inputs as the stuck transaction but pays additional fee usually by reducing the amount of bitcoin for the change output and leaving the extra value as additional fee.
