Your Bitcoin has been sitting there for hours, maybe even days, and you have found a BTC accelerator promising to get it confirmed faster. A legitimate BTC accelerator only needs your transaction ID (TXID) and nothing else. It should never need your seed phrase, private key, or wallet credentials.
That matters because BTC Afterburner, a tool other âbest ofâ lists still recommend, runs on Samourai Wallet. U.S. authorities shut down Samourai Wallet in 2024, and its former domain was later taken over and used as a phishing site in 2026.
A BTC accelerator can rebroadcast your transaction or submit it through a mining-pool partner for priority processing. Below, we have checked which tools are currently live, what they charge, what they require from you, and whether BitTools is still legitimate.
Top 10 BTC Accelerators in 2026
1. Fujn
Fujn is a Bitcoin transaction accelerator that offers a free acceleration option without requiring a sign-up.Â
The main appeal is the low barrier to entry. You do not need to create an account before trying the free option. There is no sign-up step, so you can start in the time it takes to paste a TXID.
Fujn also states that its free acceleration has eligibility limits, including a transaction-size requirement. That means not every transaction will qualify for the free route.
Free or paid: Both
What you need: TXID
Best for: Users looking for a straightforward accelerator without account setup
2. ViaBTC
ViaBTC is one of the better-known mining-pool-backed options in the BTC accelerator space. It offers both free and paid acceleration, although the free service has a limited hourly quota.
Its free service is also limited to eligible transactions, including transactions no larger than 0.5 KB and meeting its minimum fee-rate requirement. The paid service calculates an acceleration fee after you enter your TXID. ViaBTC says it then prioritizes the transaction through its mining-pool network.
One important tradeoff is that free slots can disappear within seconds of the hour. If the quota is full, you either have to wait for the next hourly allocation or use the paid option.
Free or paid: Limited free option + paid acceleration
What you need: TXID + ViaBTC account
Best for: Users who want acceleration backed by a large mining pool
3. BitAccelerate
BitAccelerate offers a free Bitcoin transaction accelerator that rebroadcasts transactions to multiple Bitcoin nodes. Its current site says the free service rebroadcasts through 20 popular and highly connected nodes. It also offers a premium service that uses mining-pool partners for additional prioritisation.Â
The free option does not require an account. This makes it useful if you simply want to try rebroadcasting before paying for anything.
Rebroadcasting does not magically increase your transactionâs fee. If your fee is far below what miners currently accept, simply broadcasting it again may not be enough.
Free or paid: Both
What you need: TXID
Best for: Users who want to try free rebroadcasting first
4. F2Pool Accelerator
F2Pool Accelerator requires an F2Pool account and charges an acceleration fee. You enter your TXID, and F2Pool calculates the required fee based on the transaction and current network conditions.
F2Pool says it has partnered with multiple mining pools, allowing an acceleration request to be processed when a participating pool produces a block.
The main trust signal is that the accelerator is directly connected to an established, identifiable mining pool rather than an anonymous third-party site.
Free or paid: Paid
What you need: TXID + F2Pool account
Best for: Users who want a mining-pool-backed accelerator
5. 360 BTC Accelerator
360 BTC Acceleratorâs free route is currently temporarily unavailable, while its paid route remains available. The paid service has been listed at $25, although users should confirm the live price before submitting a payment.
The more useful information for a reader is simply that its free option is currently paused and the paid route is the one available.
Free or paid: Free tier temporarily paused; paid tier available
Current paid price: $25
What you need: TXID + payment
Best for: Users who are willing to pay while the free option is unavailable
6. BTC Nitro
BTC Nitro has an active service that offers standard and premium acceleration options. The standard route focuses on rebroadcasting your transaction, while the premium route uses partner mining infrastructure to give the transaction higher priority.
The key point is that a paid accelerator still cannot control when Bitcoin miners produce the next block. A service can improve your transactionâs chances of being selected, but it cannot control the network.
Free or paid: Both
What you need: TXID
Best for: Users comparing free rebroadcasting with paid priority processing
7. Mempool Accelerator
Mempool Accelerator is operated by the Mempool project behind mempool.space. It uses an out-of-band fee to ask mining-pool partners to prioritize your transaction.
You submit your TXID, choose a target fee rate, and pay the calculated acceleration cost. The service currently accepts several payment methods, including Lightning, and displays the estimated cost before acceleration.
One useful trust signal is transparency. Mempool publishes acceleration activity and provides public information about how its accelerator works.
The service is paid, so it is not the first option to try if your transaction can reasonably wait or if a free rebroadcast is likely to help.
Free or paid: Paid
What you need: TXID + payment
Best for: Users who want a Bitcoin-focused accelerator with publicly documented infrastructure
8. Binance Pool Accelerator
Binance Pool operates a paid BTC Transaction Accelerator that lets users enter their transaction ID, see an estimated cost, and pay to accelerate the transaction. Its trust signal is that it is tied to a large exchange, Binance.
Unlike a basic TXID-only tool, Binance requires users to log in, and published terms also state that users must have a verified account to use the accelerator.
The service works with partner mining pools, meaning another pool may ultimately mine the block containing your transaction. Acceleration requests cannot be cancelled and are not refundable, so check the estimated cost carefully before submitting.Â
Free or paid: Paid
What you need: TXID + verified Binance account
Best for: Existing Binance users who already have a verified account
9. CoinEx BTC Accelerator
CoinEx provides a paid BTC transaction accelerator through its block explorer. You log in, enter your transaction ID, calculate the acceleration fee, and make the required payment.
Its service works with mining-pool infrastructure to increase the likelihood that a transaction is confirmed sooner.
Note that acceleration requests are non-refundable once submitted. CoinEx also makes clear that confirmation time cannot be guaranteed because it depends on network congestion and block production.Â
Free or paid: Paid
What you need: TXID + CoinEx account
Best for: Existing CoinEx users who want a paid acceleration option
10. BitTools
BitTools is not the free-only, no-signup tool it used to be. Its current site lists multiple service tiers:
- Free BTC rebroadcast: $0
- Auto BTC Re-broadcast: $15
- Enhanced Pro Acceleration: $25
- VIP Mining Priority: private-node fee + $50
- Lifetime Pro membership: $50
The free tier requires no registration and provides a manual rebroadcast. The paid tiers add automated monitoring, enhanced processing, or higher-priority infrastructure.
BitTools is currently live, and its free tier requires no account, a reasonable way to test whether the service is legitimate before paying for anything.
If your transaction qualifies, you can start with the free rebroadcast instead.
Free or paid: Both
Current pricing: $0 to $50+, depending on the service
What you need: TXID; account for paid tiers
Best for: Users specifically searching for BitTools and comparing its current free and paid options
Your TXID is all anyone needs
Every tool worth trusting shares one thing: it only needs your TXID to find your transaction.
A TXID is public information that identifies a Bitcoin transaction. An accelerator needs it to locate the transaction, rebroadcast it, calculate an acceleration fee, or submit it to a mining-pool partner. It does not need your seed phrase or private key.
What do you do with your BTC once the accelerator has done its job and your transaction has been confirmed?Â
Once itâs confirmed, convert your BTC to Naira or Cedis with Breetâ . Breet lets you sell your BTC directly for local currency and receive the value in your bank account in minutes, without waiting for a P2P buyer to complete the payment.
Skip the P2P wait; once it confirms, sell straight to your bank.
Frequently asked questions
What is a Bitcoin transaction accelerator?
A Bitcoin transaction accelerator is a service that helps an unconfirmed transaction get confirmed sooner by rebroadcasting it or submitting it through mining-pool infrastructure for priority processing.
Are Bitcoin accelerators safe to use?
Yes, as long as the site only asks for your TXID. The moment it asks for a seed phrase, private key, or wallet connection, stop. Your TXID is safe to share, but your seed phrase and private key are not. If an accelerator asks for either, stop using the site.
Is BitTools legit?
BitTools is legit and currently operating. It does not require private keys or wallet credentials for its free rebroadcast service.Â
Why is my Bitcoin transaction stuck in the mempool?
A Bitcoin transaction can remain unconfirmed when its fee rate is low compared with the transactions competing for available block space. Network congestion can make the wait longer.â
Whatâs the difference between an accelerator, RBF and CPFP?
A Bitcoin accelerator is a third-party service that can rebroadcast your transaction or offer miners an additional incentive to prioritize it. RBF, or Replace-by-Fee, lets you replace an eligible unconfirmed transaction with a new one carrying a higher fee. CPFP, or Child Pays for Parent, uses a new transaction with a higher fee to encourage miners to confirm the original transaction along with it.
How much does a BTC accelerator cost?
BTC accelerators range from free to $50 and above. Some services use fixed prices, while others calculate the cost based on the transaction and current network conditions. Always check the live price before paying.
Whatâs the longest a Bitcoin transaction can take?
There is no guaranteed maximum confirmation time. A transaction can remain unconfirmed for hours or longer, particularly when its fee is low relative to current network demand. In some cases, an unconfirmed transaction can eventually be dropped from a nodeâs mempool rather than confirmed.â
