15 Best (BTC) Bitcoin Transaction Accelerators (2025)

Need a BTC accelerator because your transaction got stuck?

You’re in the right place.

if you made a Bitcoin transaction, and it’s been over the estimated 10 minutes of confirmation time, but it’s still pending, don’t worry. You haven’t lost your Bitcoin; it’s simply stuck in the mempool.

We’ll talk about the mempool in a bit – just keep in mind that your Bitcoin is safe there. The reason your BTC is pending or stuck could be because of the low gas fee you used in processing your transaction. 

This happens because the miners who confirm your transaction and add them to the blockchain prioritise transactions based on high gas fees.  So, your transaction may be on the queue but is not being chosen to be added to the block because of a low gas fee.

However, a low gas fee is not the only possible reason for your transaction being stuck.

It could also be the age, size, and time of the transaction.  You could have processed your transaction when the miners were swamped. Or maybe, there are tons of transactions before yours, and you just have to wait your turn.

While in the mempool, your transaction (in extreme cases) may take a day or even some days to confirm. In rarer cases, the transaction may be forgotten, and your BTC returned to your wallet. 

Now, let’s talk about the mempool to better understand what goes on in there and how you can navigate the system better. 

What You Should Know About The Bitcoin Mempool Congestion

The mempool is the short form of the “memory pool.” Mempool is where pending transactions that have been validated “live” until confirmed on a block. 

When you make a Bitcoin transaction, it is broadcasted to miners, after which it is picked up and verified by all the available nodes. Each node has its own mempool built into the system with a default size of 300MB to hold unconfirmed transactions.

The nodes then remove the transaction from their mempool when it has been added to a block. 

You may wonder why there’s a hold-up if it is this straightforward. 

Well, as is with demand and supply, transaction fees can go really high or low, depending on the transaction load to be confirmed. 

Nodes have the liberty to set a minimum threshold for their transaction fee. This is where they start to kick out transactions with lower fees from their mempool. Nodes then prioritise higher transaction fees, leading to stuck transactions. 

Transaction fees in Bitcoin are not dependent on the amount of BTC but rather the space it will take up on the block. This is why it is charged in satoshis/vBytes.

Basically, what you’re paying for is the block space. This is why you need to incentivize the miners to prioritize your transaction on the block. 

Sidenote: Satoshis is the minimum unit of Bitcoin, and 1 BTC = 100 million satoshis. While vBytes is Virtual  Kilobytes.

How Can I Speed Up My Bitcoin Transaction?

For other reasons like; age, time, and transaction size, you can try sending your BTC at non-peak periods — like the weekends. 

However, you may need other alternatives to push your transaction because BTC processes an average of 7 transactions per second and 608,400 daily.

Most traders whose transactions have been held up due to low gas fees resort to some means to accelerate the confirmation time. One of the most popular tools used is Bitcoin Accelerators — the whole point of this blog post. 

So, What Is A Bitcoin Transaction Accelerator?

As the name suggests, a BTC accelerator helps you hasten your confirmation time despite network congestion or high miners’ fees. Bitcoin accelerators work by rebroadcasting your transaction on the system.

Would you say you’re shocked to learn that miners often run these accelerators? I know I’m not. 

So, instead of recalling your transaction, accelerators give it a boost and push them to be confirmed in the following block. Free and paid accelerators are available; just submit your transaction ID for rapid processing. 

Individuals and businesses can use accelerators to bypass delays and ensure that transactions are unstuck on the network.

Frequently Asked Questions (FAQs) on BTC Accelerators

Do Bitcoin Accelerators Work?

BTC Accelerators present a tricky situation where you have no way to confirm that your transaction is being prioritized. However, your best bet is to ensure that you use a reliable and trustworthy service to boost your transaction, especially because most accelerators don’t refund you. 

How To Rebroadcast Bitcoin Transaction

There are three major ways to rebroadcast your transaction; Replace-by-fee (RBF), Bitcoin Accelerators, and Child Pay For Parent (CPFP). 

RBF is when you try to re-send a transaction by increasing the miner’s fee. To do this, you have to use a wallet that supports RBF.

Bitcoin accelerators are third-party tools often run by miners. It requires you to input your transaction ID and rebroadcast your transaction, reminding miners that it needs confirmation.  

CPFP works similarly to RBF. However, you have to create a child transaction with a higher miner’s fee to support your unconfirmed transaction. In the mempool, miners must confirm the parent transaction before moving on to the child transaction. 

Why Is My Bitcoin Transaction Stuck In The Mempool?

Bitcoin’s growing popularity and use means its 1 MB block size is not as accommodating for the transaction load on the network. So, several reasons can cause your transaction to get stuck in the mempool.  Some are:

1. Low transaction fees
2. Network congestion
3. Age, time, and size of the transaction
