Frequently Asked Questions

BTCBoost is a free Bitcoin transaction accelerator service. It rebroadcasts your unconfirmed TXID to major Bitcoin mining pools, increasing the probability of your transaction being included in the next block.

Yes, BTCBoost is completely free. There are no hidden fees, no subscriptions, and no account required. We accelerate up to 100 transactions per hour on our free plan.

No. Just paste your Bitcoin TXID into the form and click Accelerate. BTCBoost requires zero registration, zero email, and zero personal information.

BTCBoost is completely non-custodial. We only receive your TXID — a public identifier that anyone can see on the blockchain. We never ask for your private key, seed phrase, or wallet access. Your funds are always under your full control.

Your transaction is likely stuck because the fee rate you set (in sat/vB) is lower than what miners are currently prioritizing. During periods of high mempool congestion, miners pick the highest-fee transactions first, leaving low-fee transactions waiting for hours or even days.

BTCBoost submits your TXID directly to the transaction priority queues of top mining pools. This signals to miners that your transaction should be considered for inclusion in the next block, even if the fee is relatively low.

Most accelerated transactions confirm within 1–3 Bitcoin blocks, which is approximately 10–30 minutes. However, confirmation time depends on current mempool congestion, your original fee rate, and miner decisions. Very low-fee transactions (below 1 sat/vB) may require longer or additional measures.

No service can guarantee Bitcoin transaction confirmation, as miners independently decide which transactions to include. However, BTCBoost significantly improves your chances by broadcasting to mining pools that collectively control ~78% of the Bitcoin network hashrate.

You can accelerate transactions that are still unconfirmed (in the mempool). If a transaction has already been confirmed, acceleration is not needed. Transactions that have already been dropped from the mempool (usually after 2 weeks of inactivity) cannot be accelerated without rebroadcasting from the sender's wallet.

If your transaction has been in the mempool for many hours at a very low fee rate, consider using RBF (Replace-By-Fee) from your wallet to bump the fee, or ask the recipient to use CPFP (Child Pays for Parent). See our How It Works page for details.

A Transaction ID (TXID) is a unique 64-character hexadecimal string that identifies a specific Bitcoin transaction. You can find it in your wallet under the transaction details, or on any Bitcoin block explorer like mempool.space.

Sat/vB stands for satoshis per virtual byte — the unit used to measure Bitcoin transaction fee rates. A higher sat/vB means miners are more likely to prioritize your transaction. During low congestion, 10–20 sat/vB is typically sufficient; during high congestion, 50–200+ sat/vB may be needed.

Replace-By-Fee (RBF) is a feature that allows a sender to replace an unconfirmed transaction with a new one that has a higher fee. It's the most reliable way to speed up a stuck transaction if your wallet supports it (e.g., Electrum, Bitcoin Core, BlueWallet).

Child Pays for Parent (CPFP) is a technique where you create a new transaction that spends an output from an unconfirmed transaction, with a high enough fee to incentivize miners to confirm both. It's useful when you're the recipient and can't use RBF.

Open your Bitcoin wallet and navigate to the transaction you want to accelerate. Look for 'Transaction ID', 'TXID', or 'Hash' in the transaction details. It will be a 64-character string of letters and numbers. You can also search your Bitcoin address on mempool.space to find your transactions.

BTCBoost broadcasts to major pools including ViaBTC, BTC.com, Foundry, AntPool, F2Pool, and Binance Pool. Combined, these pools represent approximately 78% of the current Bitcoin network hashrate.

The free plan allows up to 100 accelerations per hour. There is no daily limit — if you stay within the hourly limit, you can accelerate as many transactions as needed.

No. BTCBoost does not modify your transaction in any way. We rebroadcast it as-is to mining pools. Your fee remains exactly what you originally set. To actually increase the fee, you need RBF or CPFP from your wallet.
