How to Clear Stuck Bitcoin Transactions from the Mempool

How to Clear Stuck Bitcoin Transactions from the Mempool
Selene Marwood / Dec, 19 2025 / Crypto Guides

Ever sent a Bitcoin transaction and watched it sit there for hours-maybe even days-without moving? You’re not alone. Thousands of users face this every week, especially during spikes in network activity. The transaction doesn’t disappear. It doesn’t fail. It just… hangs. Trapped in the mempool, the temporary holding area for unconfirmed Bitcoin transactions. This isn’t a glitch. It’s how Bitcoin works when fees are too low. But here’s the good news: you can clear it. And you don’t need to be a developer to do it.

Why Transactions Get Stuck in the Mempool

The Bitcoin network doesn’t process transactions instantly. Miners pick transactions from the mempool and bundle them into blocks every 10 minutes or so. But they don’t pick randomly. They pick the ones with the highest fees first. That’s how the system stays efficient. If your transaction has a fee that’s too low compared to what others are paying, it gets pushed to the back of the line. And if the mempool is full-like during a price surge or big institutional trade-it can stay there for days.

Most Bitcoin nodes automatically drop transactions after 72 hours. Some wait up to 14 days. But waiting isn’t always practical. You might need those funds for a payment, a trade, or to rebroadcast with a higher fee. That’s where action comes in.

Method 1: Replace-by-Fee (RBF)

Replace-by-Fee is the cleanest, most direct way to fix a stuck transaction-if your wallet supports it. RBF lets you create a new transaction that replaces the old one, with a higher fee. The network sees it as a revision, not a double-spend. Miners will prioritize the new version because it pays more.

You need two things:

  • A wallet that supports RBF (Electrum, Sparrow, and some versions of Bitcoin Core do)
  • Extra Bitcoin to cover the increased fee
Here’s how to do it in Electrum:

  1. Open your wallet and go to the History tab.
  2. Find the stuck transaction and right-click it.
  3. Select “Replace by fee.”
  4. Set a new fee rate. Use mempool.space to see the current average fee. Aim for at least 1.5x the current rate.
  5. Confirm and broadcast.
If done right, the replacement transaction confirms in 10 to 30 minutes. Some wallets even let you send the funds back to yourself instead of the original recipient-effectively canceling the original send.

Method 2: Child Pays for Parent (CPFP)

What if you didn’t use RBF? What if the wallet you used doesn’t support it? Or worse-what if you sent Bitcoin to someone else, and now they’re stuck?

That’s where CPFP comes in. It’s a clever workaround that lets the recipient of the stuck transaction speed things up.

Here’s how it works: The recipient creates a new transaction that spends the unconfirmed output from your stuck transaction. They add a high fee to this new transaction. Miners see the combined fee of both transactions-the original (parent) and the new one (child)-and are incentivized to confirm them together.

This method doesn’t require the sender to do anything. It’s entirely in the hands of the receiver. That’s why it’s so useful for exchanges, merchants, or anyone receiving payments on-chain.

You’ll need:

  • Access to the receiving wallet
  • Sufficient Bitcoin to pay the child transaction fee
  • A wallet that lets you manually set fees (Electrum, Sparrow, or Bitcoin Core)
The trick is making the child transaction’s fee high enough to make the whole package attractive. A fee of 80-100 satoshis per byte usually does the job during moderate congestion.

Method 3: Transaction Accelerators

If you don’t want to mess with technical steps, third-party accelerators exist. Services like BitAccelerate, ViaBTC, or Mempool Accelerator let you pay a fee to have your transaction prioritized by mining pools they have direct connections with.

These services work best during medium congestion. During extreme spikes, even accelerators can’t guarantee speed. And not all are trustworthy. Some charge $5-$20 and never confirm your transaction.

Use them only if:

  • You’ve tried RBF and CPFP and they didn’t work
  • You’re on a tight deadline
  • You’re willing to pay extra for convenience
Always check reviews and confirm the service connects to major mining pools. Avoid services that ask for your private keys.

A woman in a cozy cabin watches a transaction transform into a bird as it rises through a starry mempool on her screen.

Method 4: Wait It Out

Sometimes, the best move is no move at all.

If your transaction has a fee just below the current average, network congestion might ease. Fees drop. Miners start picking up older, low-fee transactions again. Many stuck transactions clear naturally within 3-7 days.

This works especially well if you sent the transaction during a known peak-like after a Bitcoin ETF news drop or a major exchange deposit surge. The mempool clears faster than you think once the rush passes.

Use mempool.space to track the mempool size and fee trends. If the graph is trending down, patience pays.

Method 5: Double-Spend to Cancel (Advanced)

This is a last-resort method. It involves creating a new transaction that spends the same inputs as the stuck one, but sends the funds back to your own wallet-with a much higher fee. If this new transaction confirms first, the original one becomes invalid.

This isn’t supported by most wallets. You need to manually construct the transaction using Bitcoin Core or a tool like BitcoinJS. It’s risky. If you mess up the inputs or fee, you could lose funds.

Only attempt this if:

  • You understand UTXOs and transaction structure
  • You’ve backed up your wallet
  • You’re comfortable using command-line tools
Most users should avoid this unless they’re technically experienced.

How to Prevent Stuck Transactions in the Future

The best way to deal with a stuck transaction? Avoid it altogether.

  • Check fees before sending: Always use a fee estimator like mempool.space or Bitcoin Fee Calculator. Don’t rely on default settings.
  • Use RBF-enabled wallets: Electrum, Sparrow, and Bitcoin Core all support it. Enable it by default.
  • Monitor network conditions: Avoid sending during known congestion windows-like US market open hours (8 AM-12 PM EST).
  • Consider Lightning: For small, frequent payments, use the Lightning Network. It’s instant and cheap.
Most wallets now show estimated confirmation times based on current fees. If it says “2+ hours,” that’s your warning sign. Adjust the fee before hitting send.

Tools You Need

You don’t need fancy software. Just these:

  • mempool.space - Real-time mempool data, fee estimates, transaction tracking
  • Electrum Wallet - Best for RBF and CPFP on desktop
  • Bitcoin Core - Full node, most control, steeper learning curve
  • Sparrow Wallet - Great for advanced users, excellent CPFP tools
Avoid web wallets that hide fee controls. If you can’t see or adjust the fee, you’re flying blind.

What Doesn’t Work

There’s a lot of misinformation out there. Here’s what to ignore:

  • “Rebroadcast the same transaction” - That won’t help. Miners already saw it. They won’t see it again unless the fee changes.
  • “Use a different node” - Nodes don’t mine. They just relay. Changing nodes won’t speed things up.
  • “Wait for a hard fork” - No fork will clear your transaction. Bitcoin’s rules stay the same.
Stick to the five proven methods. Anything else is a scam or a myth.

Real-World Example

Last month, a user in Wellington sent 0.5 BTC to a crypto exchange. The fee was set at 15 sat/vB. The network average was 80. The transaction sat for 5 days. They used Electrum to enable RBF, bumped the fee to 95 sat/vB, and added 0.0003 BTC extra. The replacement transaction confirmed in 18 minutes. Their funds arrived. No loss. No panic.

That’s the power of knowing how to act.

How long does a stuck Bitcoin transaction usually take to clear?

Most stuck transactions either clear within 72 hours or get dropped by nodes. Some can linger up to 14 days. But if the fee is too low, it may never confirm unless you use RBF, CPFP, or an accelerator. Don’t wait longer than 5 days without taking action.

Can I cancel a Bitcoin transaction after sending it?

You can’t directly cancel it, but you can replace it with a higher fee (RBF) or use CPFP if you’re the recipient. If the transaction drops from the mempool after 72-336 hours, you can rebroadcast with a higher fee. There’s no official undo button in Bitcoin.

Do I need extra Bitcoin to clear a stuck transaction?

Yes, for RBF and CPFP. You need additional Bitcoin to cover the higher fee. For example, if your original transaction had a 10,000 satoshi fee and you need to bump it to 50,000, you’ll need 40,000 extra satoshis to pay the difference. This isn’t a cost-it’s just using your own funds more efficiently.

Why won’t my wallet let me do RBF?

Your wallet may not support RBF, or you may have sent the transaction without enabling it. RBF must be enabled at the time of sending. Wallets like Exodus, Trust Wallet, and most mobile apps don’t support it by default. Use Electrum or Bitcoin Core if you want RBF control.

Is it safe to use a transaction accelerator?

It’s safe if you use a reputable service and don’t give away your private keys. Stick to well-known accelerators like BitAccelerate or Mempool Accelerator. Avoid services that ask for your seed phrase or wallet password. Never trust a service that promises “guaranteed” confirmation without transparency.

    I swear Bitcoin is just a cosmic joke sometimes
    One minute you're sending funds to pay rent, the next you're staring at a transaction that's been stuck longer than my last relationship
    Why does it feel like the network is judging me?

    RBF is the way to go if your wallet supports it. Simple, clean, and works every time. Just make sure you have a little extra BTC to bump the fee. No drama.

    You people act like this is some kind of crisis. Bitcoin was designed to be slow and expensive. If you can't afford the fee, don't use it.

    Stuck tx? Nah man, just let it breathe. The mempool is like a busy Lagos traffic jam - eventually the cars move, even if the horn blows for days

    CPFP is fake. Miners don't care about your child transaction. They only care about the highest fee per byte. Stop lying to yourselves.

    The methodology outlined herein is both technically sound and pragmatically viable. However, one must consider the macroeconomic implications of fee manipulation within a decentralized consensus mechanism.

    You're all missing the point. Bitcoin Core is the only legitimate wallet. If you're using Electrum or Sparrow, you're already compromised. And no, RBF is not 'safe' - it's a protocol-level vulnerability.

    Hey, don't stress. I've had txs sit for a week before. Just use mempool.space to track it. Sometimes patience is the best tool you've got.

    This post is just fearmongering. Most people who get stuck are just lazy and didn't check fees. You're not special. Your tx isn't important.

    I used to panic every time a tx got stuck. Then I learned to just breathe. RBF saved me three times. Now I always enable it. You got this.

    The mempool is a liquidity pool, not a queue. You're conflating fee markets with transaction ordering. Also, CPFP is an anti-pattern.

    I just sent my mom a Bitcoin payment and she thought it vanished 😅
    Thank you for explaining RBF and CPFP so clearly - now I can help her without making her cry 🤍

    Always. Check. The. Fee. Before. You. Hit. Send. I can't believe how many people don't do this. It's so simple. Seriously. Just check it.

    The very notion of 'clearing' a transaction implies a central authority. Bitcoin's immutability is its virtue. Perhaps the mempool's silence is a metaphysical test.

    I just used RBF and my tx confirmed in 12 minutes. I cried. Not because I was happy - because I realized I'd spent 5 days worrying over a 0.0003 BTC fee
