Bitcoin Transaction Accelerator

A Bitcoin transaction accelerator is a service that helps an unconfirmed transaction get into a block sooner. A free accelerator rebroadcasts your already-signed transaction to well-connected nodes. A paid (premium) accelerator arranges for mining pools to include your transaction in the blocks they mine, even though its on-chain fee is below the current market rate.

Each block has limited space, and miners fill it with the transactions that pay the most per virtual byte (sat/vB). If your wallet set a fee rate that was too low — or fees rose after you sent — your transaction waits in the mempool. Unconfirmed parent transactions and poor propagation can also delay it. Read the full explanation.

It depends on the package: within 1 hour (Standard), 45 minutes (Fast), 30 minutes (Priority) or 10 minutes (Express), counted from the start of acceleration. Bitcoin blocks arrive at random intervals, so these are targets — and if your transaction is not confirmed within 24 hours, you get a full refund.

Choose a speed package: Standard $20 (confirmed within 1 hour), Fast $50 (within 45 minutes), Priority $100 (within 30 minutes) or Express $200 (within 10 minutes). The higher the package, the higher the priority your transaction gets.

It helps when the problem is propagation — for example if your transaction was dropped by some nodes or never reached miners properly. It cannot change the fee, so if your fee rate is far below the market, a rebroadcast alone rarely speeds things up. In that case use RBF, CPFP or premium acceleration.

Open your wallet's transaction history, tap the pending transaction and copy the “Transaction ID”, “TXID” or “Hash”. Exchanges usually show it in the withdrawal details. It is a 64-character string of letters a–f and digits. You can also paste a block-explorer link — we extract the TXID automatically.

No — never. The accelerator only uses your public TXID. Nobody can move your coins with it. Never share a seed phrase or private key with any accelerator; legitimate services do not need them.

Almost every valid unconfirmed transaction can. Exceptions: transactions that are already confirmed, replaced or double-spent, non-standard transactions, or extremely large packages. Our checker tells you before you pay — you are never charged for a transaction we can't accept.

The order page notices it and cancels the invoice automatically, so you don't pay for nothing.

Often yes. With Replace-by-Fee (RBF) you resend the same payment with a higher fee. With Child-Pays-for-Parent (CPFP) the receiver spends the incoming coins with a high fee so miners take both. Our CPFP calculator tells you the exact fee needed.
