There is no guaranteed confirmation time. A relay accepting a transaction does not mean it has been mined. If it is already widely propagated, rebroadcasting may make no difference. Check the fee estimates and your wallet’s RBF or CPFP options if you need to increase its fee.

Yes. Zest's BTC TX accelerator is completely free. There are no hidden fees, no account required, and no premium tier. You only need your transaction ID (txid).

A txid is the unique 64-character hexadecimal identifier assigned to every Bitcoin transaction when it is broadcast. You can find it in your wallet's transaction history, or by checking the send confirmation your wallet showed you. It looks like: a1b2c3d4…

Yes — anyone who knows the txid can rebroadcast it. This is useful if a counterparty sent you funds but their node did not propagate the transaction widely.

The most common cause is a fee rate that was set too low. If network congestion increased after your transaction was broadcast, higher-fee transactions jump the queue. A secondary cause is poor initial propagation — the transaction wasn't relayed to enough nodes. Rebroadcasting addresses the second cause; RBF or CPFP addresses the first.

RBF is a Bitcoin protocol feature that lets a sender replace an unconfirmed transaction with a higher-fee version that spends the same inputs. Most modern wallets (Bitcoin Core, BlueWallet, Electrum) enable RBF by default. If your wallet shows a 'Bump Fee' or 'Replace' option, that is RBF.

CPFP lets the recipient of an unconfirmed transaction speed it up. You spend the unconfirmed incoming output in a new transaction with a high fee. Miners must include the stuck parent transaction to earn the child's fee, so they have an incentive to confirm both together.

Yes. The accelerator rebroadcasts any valid raw Bitcoin transaction regardless of address type — legacy (P2PKH), SegWit (P2WPKH/P2WSH), and Taproot (P2TR) are all supported.

There is no network-wide expiry deadline. Nodes can remove unconfirmed transactions according to their own memory and expiry policies, while other nodes may still have them. A missing explorer result does not cancel a payment. Check your wallet and whether the inputs are still unspent before attempting a replacement.
