Bitcoin transaction stuck? Bump it with RBF or CPFP
Paste the transaction id. You see the fee rate it paid, the rates confirming now, and exactly what a replacement or a child transaction would have to pay.
Or enter fee and size by hand
Rules: BIP-125 (Replace-by-Fee). CPFP: child fee = target rate × (parent vB + child vB) − parent fee.
Questions and answers
Why is my Bitcoin transaction unconfirmed?
Miners fill blocks with the transactions that pay the highest fee rate. If yours pays less than the rate currently needed, it waits until demand falls or it is bumped.
What is Replace-by-Fee (RBF)?
Sending a new version of the same transaction with a higher fee. BIP-125 sets the rules: the replacement must pay a higher absolute fee and cover its own relay cost. Most wallets show a “bump fee” or “speed up” button for it.
What is Child-Pays-for-Parent (CPFP)?
Spending an output of the stuck transaction (for example your change) in a new transaction with a high fee. Miners take both together when the combined fee rate is attractive. The child must pay for the parent's size as well as its own.
Do I need a paid transaction accelerator?
No. RBF and CPFP are free features of Bitcoin wallets; the only cost is the higher network fee shown above. This site does not link to paid accelerators.
Is the transaction id I enter stored?
No. It is checked, passed once to the data hub, which asks a public Bitcoin API, and kept only in a short cache. It is not written to disk or logged.
