BitAccelerate

BitAccelerate is a free Bitcoin transaction accelerator that enables faster confirmations for your unconfirmed transactions. It operates by rebroadcasting transactions to 20 popular and highly connected Bitcoin nodes.

Additionally, we provide a premium acceleration service for most transactions, available for a fee. With this service, transactions receive priority confirmation by the miners. We are partnering with some of the largest mining pools.

As more people start to use Bitcoin, the block size reaches its limit, leading to a crowded Bitcoin network. Consequently, low-fee transactions are delayed, and sometimes even dropped (purged) from the confirmation queue (mempool).

It often occurs that the network becomes congested immediately after you have sent your transaction, especially when the price of Bitcoin is rapidly rising. In such cases, even if your initial fee was sufficient, it may no longer be adequate due to changed market conditions.

In such situations, you need to take measures to expedite your transaction. You can use a transaction accelerator, RBF (if the transaction supports it), or CPFP (if you control any of the transaction's outputs). Otherwise, you may have to wait days, weeks, or even months for the transaction to be confirmed.

Transaction rebroadcasting aids in the following ways:

• Rapid propagation of new transactions. If the transaction carries a lower fee compared to the prevailing market rate, Bitcoin nodes prioritize distributing other transactions with higher fees. Consequently, it is common for major mining nodes to remain unaware of your transaction if it hasn't reached them.
• Mining nodes become aware of your transaction. This is important, especially when the network is congested. Your fee might be enough, but the miners don't know about your transaction. When you launch a new transaction, the rebroadcasting service helps to start mining blocks with it faster.
• Some miners do not have access to the entire mempool. Often, we observe blocks being mined with transactions that may not be the most optimal at that moment. Consequently, there's a possibility for your transaction to be confirmed, even if there are others with higher fees. This happens because miners are aware of your transaction but might not be aware of others.
• Re-committing the transaction to the mempool after purging. When the mempool becomes congested with numerous transactions, most nodes begin purging those with lower fees. Utilizing the rebroadcasting service, you reinsert your transaction. This becomes particularly crucial when network load diminishes, as it is the sole method to reintroduce your transaction into the mempool.
• It should also be noted that Bitcoin nodes are configured by default to drop transactions from the mempool if they are older than 14 days. This means that transactions not confirmed within this period are forgotten. In such cases, our free service can help restore them.
• You can distribute transactions with a lower fee than what most nodes can currently accept. The reason is that we are working with nodes set to support a larger or even unlimited mempool. Thus, these nodes will take care of the propagation of your transaction to ensure it does not fall out of the mempool of other nodes.

Transaction rebroadcasting can be beneficial in certain situations, particularly when the network is not excessively congested. However, it should be noted that this service is provided free of charge and cannot be compared to the prioritization of transactions by mining pools. In heavily congested networks, its impact may be minimal. In such cases, it is advisable to consider alternative forms of transaction acceleration.

A Bitcoin Transaction ID (TxID) is a unique identifier assigned to each transaction that occurs on the Bitcoin blockchain. It serves as a way to track and verify transactions on the network. The TxID is typically a 64-character-long string of letters and numbers, represented in hexadecimal format.

If you're using a Bitcoin wallet software or service, there is usually a transaction history or activity section where you can view details of your transactions, including the TxID. Once you have the TxID, you can use it to track the status of the transaction on the blockchain explorer or to accelerate the transaction via this service.

With our free rebroadcast service, we cannot commit to any time frames or guarantee any outcomes.

With the premium service, transactions are typically confirmed within 1 to 4 hours after payment to us. However, it may take longer, especially when the network is heavily congested and we have a lot of service orders.

There are cases where the mining pool to which we have submitted the transaction for priority confirmation encounters bad luck and takes more time to find a block containing the corresponding transaction.

In general, we cannot commit to any specific timeframes because there are many factors that affect the confirmation of a transaction. As you can see, even luck plays a significant role.

You can use one of the following techniques to speed up your transaction confirmation yourself:

• The current transaction rebroadcasting service. It's free, so it won't cost you anything to try. If you're concerned about your privacy, rest assured that we keep absolutely no data from the transactions we distribute for free.
• Replace-by-fee (RBF). If your transaction is RBF-enabled, you can bump its fee via your wallet. This is the easiest and most standardized approach.
• Child Pays For Parent (CPFP). If you have control over any of the transaction's outputs, you can accelerate it using CPFP. We offer a free CPFP calculator to help you determine the exact feerate required for the second transaction.

We also offer a tool for broadcasting raw Bitcoin transactions.
