Frequently asked questions

Why is my Bitcoin transaction stuck or unconfirmed?
A Bitcoin transaction stays unconfirmed when its fee rate (sat/vB) is too low for current mempool demand. Miners pick the highest fee-rate transactions first, so a low-fee transaction can wait hours or days until the mempool clears or you boost its priority.
What is a Bitcoin transaction accelerator and is it free?
A transaction accelerator asks a mining pool to prioritise or rebroadcast your transaction so it confirms faster. Some pools offer a limited free queue, but most reliable acceleration is paid. Always check the cost before submitting and never share your private keys.
What is the difference between RBF and CPFP?
Replace-By-Fee (RBF) rebroadcasts the same transaction with a higher fee, and only works if the transaction signalled RBF when it was created. Child-Pays-For-Parent (CPFP) spends one of the transaction's unconfirmed outputs in a new high-fee transaction, pulling the original through with it.
How long before an unconfirmed transaction is dropped?
Most nodes drop transactions from the mempool after about 14 days if they never confirm. The coins are never lost; they simply return to spendable in your wallet, and you can resend with a higher fee.
Can an accelerator guarantee my transaction confirms?
No service can guarantee the next block, but mining-pool accelerators significantly raise the odds by prioritising your transaction. Avoid any service that asks for your seed phrase or private keys, that is always a scam.
Are Bitcoin transaction accelerators safe to use?
Reputable mining-pool accelerators only need your TXID, which is public, so they are safe. The risk is scam sites that demand upfront payment to an unknown wallet or ask for keys. Verify the operator and prefer RBF or CPFP from your own wallet when possible.
