In the fast-paced world of cryptocurrency, timely Bitcoin transactions are crucial—especially when you're conducting business or responding to market movements. But what happens when your BTC transfer gets stuck in limbo due to low transaction fees? That’s where a Bitcoin transaction accelerator comes in.
These tools help users bypass network congestion by increasing the likelihood that miners will prioritize their transactions. Whether you're a seasoned trader or new to crypto, understanding how to use these accelerators can save time, frustration, and potentially lost opportunities.
Let’s dive into how Bitcoin transaction accelerators work, why they matter, and explore five reliable services that can get your stalled BTC transactions confirmed quickly.
How Bitcoin Transactions Get Stuck
Every Bitcoin transaction must be verified and added to a block by miners. Before that happens, it enters a holding area called the mempool—a queue of unconfirmed transactions. Miners typically select transactions with the highest fees first, leaving low-fee transfers waiting, sometimes for hours or even days.
During periods of high demand—such as bull markets or major network events—the mempool can become severely congested. In late 2017, for example, over 450,000 transactions were processed daily, causing widespread delays. This is when using a transaction accelerator becomes not just helpful, but essential.

What Is a Bitcoin Transaction Accelerator?
A Bitcoin transaction accelerator is an off-chain service—often operated by major mining pools—that helps push your unconfirmed transaction into the next available block. These services do this by re-broadcasting your transaction across multiple nodes or prioritizing it within their own mining operations in exchange for an additional fee.
While not all wallets support these tools (especially hardware wallets), most software wallets allow integration with accelerators. It's important to note that these services don’t guarantee instant confirmation but significantly improve the odds—especially during peak network traffic.
Top 5 Bitcoin Transaction Accelerators
1. ViaBTC
Launched in 2017 as a response to Bitcoin’s 1 MB block size limit, ViaBTC offers both free and paid acceleration options. The free tier allows up to 100 transactions per hour, making it accessible for casual users.
For urgent cases or transactions with extremely low fees, ViaBTC provides a paid option requiring a minimum fee of 0.0001 BTC per KB. What sets ViaBTC apart is its relatively low miner fees compared to industry standards and no requirement for account registration.
Simply submit your transaction ID (TXID)—available via any blockchain explorer—and your transaction will be processed. Two-factor authentication is also supported for enhanced security.
2. BTC.com
BTC.com runs a well-regarded transaction acceleration service in collaboration with several mining pools. While not entirely free, this platform offers strong performance: according to their data, there's a 75% chance of confirmation within one hour and 98% within four hours.
Fees vary based on current network congestion. For instance, accelerating a specific transaction might cost around $12, payable in fiat or cryptocurrency. Users must sign up to receive a fee estimate, and payments are non-refundable since the acceleration process is irreversible.
This makes BTC.com ideal for users who need predictable results and are willing to pay a premium during high-traffic periods.
3. ConfirmTX
ConfirmTX offers fast processing for unconfirmed Bitcoin transactions. Transactions over 250 bytes cost $5, while smaller ones are processed for free or at minimal cost (as low as $0.01).
The service works by pushing your TXID to multiple partner mining pools, increasing visibility and selection probability. There are no refunds, but if your transaction isn’t confirmed within 72 hours, you’ll receive credit for a future acceleration.
Priority is determined by the fee paid:
- $0–$0.50: Up to 72 hours
- Over $0.50: Typically confirmed within 48 hours
Ensure your transaction doesn’t have unconfirmed inputs, as this may disqualify it from processing.
4. 360 BTC Accelerator
This completely free tool helps users speed up stuck transactions by re-broadcasting them across the network. Unlike other services, 360 BTC Accelerator doesn’t mine directly or partner with pools—it simply increases the visibility of your TXID.
By broadcasting your transaction ID to various nodes, it improves the chances of being picked up by active miners like those in the ViaBTC pool. No sign-up is required, making it user-friendly and accessible.
While it doesn’t offer guaranteed timing, consistent re-broadcasting every few hours can make a noticeable difference during moderate congestion.
5. BitAccelerate
BitAccelerate is another no-cost solution that rebroadcasts your transaction through 10 different Bitcoin network nodes. To use it, simply enter your TXID, click “Accelerate,” and wait.
You can resubmit every six hours until confirmation—though excessive submissions may result in a temporary ban. Like 360 BTC Accelerator, BitAccelerate doesn’t require login credentials or personal information.
It’s best suited for users who prefer hands-off management and don’t mind waiting a bit longer for organic miner pickup.

Frequently Asked Questions (FAQ)
Q: Do Bitcoin transaction accelerators actually work?
Yes—but only if used through legitimate platforms. Reputable services like ViaBTC and BTC.com operate with real mining influence or broad node networks. Free scams exist, so stick to known providers.
Q: Can I use accelerators with hardware wallets?
Currently, most accelerators don’t support hardware wallets directly. These tools typically work best with software wallets that allow manual TXID input or fee adjustments.
Q: Are there alternatives to using third-party accelerators?
Absolutely. Native blockchain features like Replace-by-Fee (RBF) and Child Pays for Parent (CPFP) let you increase fees without external tools. However, they require technical knowledge and compatible wallets.
Q: How long does acceleration usually take?
Results vary. With paid services like BTC.com, confirmation often occurs within 1–4 hours. Free options may take up to 72 hours depending on network load and fee levels.
Q: Is there a risk of losing funds when using an accelerator?
No—your funds aren’t at risk as long as you use legitimate services and provide the correct TXID. Accelerators don’t access your private keys or wallet balance.
Q: Why not just wait it out instead of paying?
You can wait, but during high congestion, low-fee transactions may take days—or get dropped entirely. If timeliness matters, acceleration is a cost-effective alternative to uncertainty.
Final Thoughts: When to Use a BTC Accelerator
Bitcoin transaction accelerators serve as valuable tools during network congestion or when you’ve accidentally set a low fee. While blockchain-native solutions like RBF are preferable long-term, accelerators offer immediate relief without deep technical setup.
