Bitcoin transaction accelerator
A Bitcoin transaction accelerator helps an unconfirmed transaction get included in a block faster by ensuring its effective fee rate is high enough for the mempool. You provide the transaction and the accelerator raises its priority so miners pick it up in the next block or two.
How acceleration works. The accelerator rebroadcasts your transaction (or a higher-fee replacement, when RBF is available) with a fee rate that clears the current mempool threshold. Nodes then relay it to miners, who include it in the next block.
What you need. Your transaction ID (TXID) and, for RBF, access to the original wallet. The accelerator then tracks the transaction until it reaches its first confirmation.
Typical time. With a fee rate above the current threshold, confirmation usually lands within the next one or two blocks — roughly 10 to 30 minutes.
Quick answers
What do I need to use a Bitcoin accelerator?
Your transaction ID (TXID). If the original used RBF, the accelerator can also raise the fee for you; otherwise it relies on the original fee becoming competitive.
Is acceleration instant?
Not instant, but fast. Once the effective fee rate clears the mempool threshold, the transaction is typically confirmed in the next block or two.
Does it work for every unconfirmed transaction?
It works best when the transaction used RBF or when the fee can be raised. A very old, low-fee transaction without RBF may need a CPFP child transaction instead.
