Questions
Can anyone guarantee to speed up my transaction?
No. Only miners decide what goes into a block. You can make your transaction more attractive by paying more (replace-by-fee or child-pays-for-parent), or pay a mining pool’s accelerator service to prioritise it in the blocks that pool mines. Anyone promising a guaranteed confirmation for a fee is not being straight with you.
What is replace-by-fee (RBF)?
The sender re-signs the same payment with a higher fee, replacing the stuck version. Wallets such as Sparrow, Electrum, BlueWallet, Trezor Suite and Bitcoin Core do this with one click. The replacement must pay at least the old fee plus a little for its own size.
What is child-pays-for-parent (CPFP)?
Whoever controls an output of the stuck transaction (the recipient, or the sender through their change) spends it in a new transaction with a high fee. Miners include both, because together they pay enough. It works even when the original does not signal RBF.
Does the free rebroadcast help?
Only when the transaction has fallen out of some nodes’ mempools (after about two weeks, or when mempools are full). Rebroadcasting cannot make a low fee attractive; it only makes sure the network still knows about it.
What about paid accelerators?
Some mining pools sell out-of-band acceleration: you pay them and they include your transaction in blocks they mine. That only helps if those pools find a block soon, and you pay on top of the fee. We link to reputable ones but have no relationship with them.
My transaction disappeared. Is my money gone?
No. If a transaction is dropped, the coins never left your wallet. Your wallet may need to rescan or “cancel” the dropped transaction before you can send again with a higher fee.
