What is a Bitcoin Transaction Accelerator?

A Bitcoin transaction accelerator is an online service designed to speed up the confirmation of Bitcoin transactions that are stuck or delayed, typically due to low transaction fees. These services are often operated by mining pools and work by rebroadcasting the transaction with higher priority to the Bitcoin network, helping it gain visibility among miners.

Accelerators are particularly useful during times of network congestion, when miners tend to prioritize transactions offering higher fees. By pushing your transaction back into the network with enhanced visibility, these tools aim to reduce confirmation delays that can sometimes stretch into hours or even days.

There are two main types of Bitcoin accelerators: free and paid. Free accelerators usually rebroadcast your transaction to affiliated mining pools without increasing the fee, making them a useful (though less guaranteed) option. Paid accelerators, on the other hand, may include fee boosting mechanisms behind the scenes to incentivize faster inclusion in the next block, offering more reliable results.

How Do Bitcoin Accelerators Work?

Let’s explore how free Bitcoin accelerators function behind the scenes:

Submission: Users begin by submitting their transaction ID (TXID) to the accelerator’s platform. This is a unique identifier for the unconfirmed transaction and serves as the key input for the acceleration process.

Prioritization: Once the transaction is submitted, the accelerator attempts to prioritize it within the mempool (the pool of unconfirmed transactions). While free services do not increase the transaction fee, they still attempt to raise its visibility among miners by resubmitting or rebroadcasting it to partner mining nodes.

Broadcasting: The accelerator then rebroadcasts the transaction across multiple nodes in the Bitcoin network. By doing so, it increases the likelihood that a mining pool will include the transaction in the next block, accelerating confirmation—especially during periods of moderate network activity.

While free accelerators may not guarantee immediate results like paid services, they remain a useful tool for increasing confirmation speed without incurring additional costs.

Pros & Cons of Using Bitcoin Accelerators

While BTC accelerators can be helpful, they are not all perfect. The following chart sets forth the pros and cons of using Bitcoin accelerators:

Top Free Bitcoin Accelerators 2025

Here are some of the top-performing free Bitcoin accelerators in 2025:

ViaBTC

ViaBTC is one of the most prominent Bitcoin mining pools and offers a widely used Bitcoin transaction acceleration service. This tool helps users speed up unconfirmed transactions—especially useful when network congestion causes delays.

ViaBTC provides both free and paid acceleration options:

• The free service allows up to 100 transaction submissions per hour, making it a popular choice for users who don’t want to incur additional fees. While confirmation is not guaranteed, this option is useful during periods of moderate network activity.
• For those needing higher reliability and priority, ViaBTC also offers a premium acceleration service. By paying a fee starting at 0.0001 BTC per kilobyte (KB) of transaction size, users can gain access to up to 1,000 transaction submissions per hour. This premium tier ensures faster inclusion in upcoming blocks, making it ideal for urgent or large-value transactions.

Thanks to its direct integration with one of the largest Bitcoin mining pools and competitive fee structure, ViaBTC remains a top choice for users looking to accelerate Bitcoin transactions efficiently—whether through the free service or the more reliable paid option.

BTC.com

BTC.com is widely regarded as one of the most reliable Bitcoin transaction acceleration services, known for its low fees, batch processing capability, and strong network integration. Its ability to accelerate multiple transactions within a single batch makes it especially popular among users who regularly process large volumes of Bitcoin transfers.

The platform offers both free and premium acceleration services:

• The premium service is priced at approximately $24 per transaction, but it stands out by allowing users to accelerate multiple transactions under a single fee, offering excellent value for high-frequency traders or service providers.
• In collaboration with several major mining pools, BTC.com’s accelerator is designed to address network congestion and reduce confirmation times. The service claims to provide a 75% chance of confirmation within the next block, typically within one hour—making it one of the more efficient options available.

A key advantage of BTC.com is its flexible fee model. Unlike some competitors, the platform does not impose a minimum fee requirement in Bitcoin, which allows users to accelerate transactions of varying sizes without needing to meet a fixed threshold.

With a solid reputation, seamless integration with major mining pools, and features that support both individual and batch users, BTC.com remains a go-to choice for those seeking dependable and flexible transaction acceleration.

BitAccelerate

BitAccelerate is a free Bitcoin transaction accelerator designed to help users push through unconfirmed transactions by rebroadcasting them across ten Bitcoin network nodes. This process increases the likelihood of the transaction being picked up by miners and included in the next available block.

One of BitAccelerate’s key advantages is its simplicity and accessibility. The service requires no registration or login, making it an ideal solution for casual users who want a quick and hassle-free way to speed up delayed transactions.

As a completely free tool, BitAccelerate is best suited for those unwilling or unable to pay for premium acceleration. Users can resubmit their transaction every six hours, a recommended practice to increase visibility until the transaction is confirmed.

However, while BitAccelerate offers convenience and zero cost, its effectiveness may be limited during times of high network congestion. In such cases, paid accelerators that offer fee-based prioritization may deliver faster and more reliable results. Still, for users seeking a no-cost alternative, BitAccelerate remains a valuable tool in the crypto space.

360 Bitcoin Accelerator

360 Bitcoin Accelerator is a free service designed to assist in confirming unconfirmed Bitcoin transactions by rebroadcasting them across multiple network nodes. Unlike paid accelerators run directly by mining pools, 360 Bitcoin Accelerator relies on network propagation to improve the chances of a transaction being picked up for inclusion in an upcoming block.

While it doesn’t offer guaranteed prioritization like premium services, it has proven effective in many cases—particularly for smaller or non-urgent transactions. According to the platform, it has successfully helped accelerate the confirmation of over 1,000 BTC transactions since its launch.

One of the service’s key strengths is its flexibility. Unlike some free tools that restrict transaction size, 360 Bitcoin Accelerator does not impose any maximum limits, making it a useful option for a wide range of users. However, during periods of high network congestion, its performance may lag behind that of fee-based alternatives.

Overall, for users seeking a zero-cost solution with no registration requirements, 360 Bitcoin Accelerator offers a convenient and flexible tool—though not always the fastest option under heavy network load.

ConfirmTX

ConfirmTX is a straightforward yet reliable Bitcoin transaction accelerator that aims to confirm transactions within 12 hours or less. The platform operates by rebroadcasting transactions to multiple mining pools, significantly increasing the chances of prompt inclusion in a mined block.

• ConfirmTX offers a transparent and user-friendly pricing model:
• Transactions larger than 250 bytes incur a flat fee of $5.
• Smaller transactions are processed free of charge, making it a cost-effective option for routine users.

To further instill user confidence, ConfirmTX provides a guarantee—if a transaction is not confirmed within 72 hours, users receive a credit for one future free acceleration. This added assurance helps mitigate the risks of occasional delays, making ConfirmTX a dependable solution for those seeking quicker Bitcoin confirmations without navigating complex fee structures.

Bitcoin Afterburner

Bitcoin Afterburner is an in-wallet accelerator tool by Samourai Wallet, allowing users to accelerate transactions directly from their mobile device using CPFP. As a mobile application that offers transaction acceleration services, Bitcoin Afterburner enables users to fund the app with bitcoins and use it to boost their unconfirmed transactions.

Key features include:

• Mobile app integration
• CPFP-powered acceleration
• Maintains user privacy
• Ideal for stuck mobile transactions

Bitcoin Afterburner is especially attractive to privacy-focused users who want to stay in control.Bitcoin Afterburner has a free option. However, it may charge a basic fee for subscriptions and minor fees associated with CPFP services. Additionally, the app simplifies the process of accelerating transactions and ensures a faster confirmation time for users.
