Bitcoin is one of the most widely used cryptocurrencies in the world, known for its decentralized nature and robust security. However, one common challenge users face is slow transaction confirmation times—especially during periods of high network congestion. When you send BTC, your transaction enters a queue where miners choose which transactions to confirm based on the fees attached. This means that if your fee is too low, your transaction could remain unconfirmed for hours or even days.
Fortunately, there’s a built-in solution: Replace-by-Fee (RBF). This feature allows users to speed up pending Bitcoin transactions by replacing them with a new version that includes a higher network fee. If you're using a wallet that supports this functionality—like Proton Wallet—you can easily accelerate your transaction and avoid long waits.
In this guide, we’ll walk through how Bitcoin transaction fees work, why some transactions get delayed, and how you can use the boost priority feature in Proton Wallet to ensure your BTC transfer goes through quickly.
Understanding Bitcoin Transaction Fees
Every time you send Bitcoin, you pay a small network fee to miners. These are individuals or groups who use powerful computers to validate transactions and add them to the blockchain. The fee acts as an incentive: miners prioritize transactions with higher fees because it’s more profitable for them.

This creates a competitive environment during peak usage times—such as when markets are volatile or during major crypto events. With many people sending BTC at once, the network becomes congested, and lower-fee transactions get stuck in the mempool (a holding area for unconfirmed transactions).
Key factors affecting transaction speed:
- Network congestion: More transactions = longer wait times.
- Fee amount: Higher fees increase confirmation priority.
- Transaction size: Larger data size (e.g., multiple inputs) requires higher fees.
While you can't control network traffic, you can adjust your fee strategy. That’s where RBF comes in.
What Is Replace-by-Fee (RBF)?
Replace-by-Fee (RBF) is a protocol rule in Bitcoin that allows a sender to replace an unconfirmed transaction with a new one that pays a higher fee. This doesn’t mean canceling the original—it replaces it so only the updated version gets confirmed.
Not all wallets support RBF, and it only works if:
- The original transaction was sent with RBF enabled.
- It hasn't been confirmed yet.
- You still control the sending wallet.
Proton Wallet automatically enables RBF for outgoing Bitcoin transactions, giving you the flexibility to boost slow transfers whenever needed.
How to Boost a Bitcoin Transaction in Proton Wallet
If your BTC transfer is stuck or taking longer than expected, follow these steps to increase its priority:
Step 1: Log In to Your Proton Wallet
Open the Proton Wallet app on your mobile device or visit wallet.proton.me in your browser. Make sure you're logged into the correct account associated with the pending transaction.
Once inside, navigate to the wallet dashboard. Your recent transactions are displayed directly on the main screen under the relevant cryptocurrency balance (e.g., BTC).
Step 2: Select the Pending Transaction
Locate the transaction that's still marked as “In progress” or “Pending.” Click on it to open the details panel on the right side of the screen.
⚠️ Note: The boost feature is only available for transactions that have not yet been confirmed and were sent with RBF enabled.
Step 3: Click "Boost Priority"
In the transaction details window, look for the Status section. You’ll see a button labeled Boost priority—click it.
A pop-up titled Boost Transaction Priority will appear. Here, you’ll see:
- The current network fee of your original transaction.
- A slider to adjust the new, higher fee.
- An estimated confirmation time based on current network conditions.
Move the slider to choose a competitive fee. The wallet will automatically calculate how long confirmation might take based on real-time blockchain data.

Once satisfied with the new fee, click Increase fee and resend. The wallet will create a replacement transaction with the updated fee and broadcast it to the network.
Step 4: Verify the Updated Transaction
After resending, return to your transaction list and click on the same entry. In the details panel, check the Network fee field—it should now reflect the higher amount you set.
The original transaction will disappear from the mempool once the new one is accepted, and miners will begin processing the updated version.
You can repeat this process multiple times if needed—though each boost increases the total cost slightly.
Tips for Avoiding Slow Bitcoin Transactions
While boosting works well, it's better to prevent delays in the first place:
- Check network congestion before sending
Use tools like mempool.space to view current fee rates and congestion levels. - Use dynamic fee estimation
Modern wallets like Proton Wallet offer smart fee suggestions based on urgency (e.g., economy, standard, fast). - Enable RBF by default
Always send transactions with RBF enabled so you retain control over unconfirmed sends. - Avoid peak hours when possible
Large price swings often trigger surges in transaction volume. Consider timing non-urgent transfers during calmer periods. - Keep small reserves for boosting
Ensure your wallet has enough funds to cover increased fees if you need to boost later.
Frequently Asked Questions (FAQ)
Q: Can I cancel a Bitcoin transaction instead of speeding it up?
A: No—once broadcast, Bitcoin transactions cannot be canceled. However, if unconfirmed, you can replace them using RBF with a higher fee or let them expire (which may take days).
Q: Why didn’t my transaction confirm even after boosting?
A: Rarely, network anomalies or extremely high congestion may delay confirmation temporarily. Try boosting again with a significantly higher fee. Most wallets prevent double-spending by invalidating old versions automatically.
Q: Does boosting cost extra money?
A: Yes—the difference between the original and new fee is paid to miners. For example, if your initial fee was $1 and you boost to $5, you pay an additional $4 in miner fees.
Q: Will boosting work if my transaction isn’t using RBF?
A: No. Only transactions originally sent with RBF enabled can be replaced. Always ensure RBF is active when making BTC transfers.
Q: How long does it take after boosting?
A: Typically within 10 minutes to 1 hour, depending on network load and your new fee level. High-priority fees often get confirmed in the next block.
Q: Is boosting safe?
A: Yes—it’s a standard Bitcoin feature supported by major wallets. It does not compromise security or expose private keys.
Final Thoughts
Bitcoin remains a powerful tool for global value transfer, but understanding how transaction fees and confirmation work is essential for smooth usage. With features like Replace-by-Fee, wallets like Proton give users control over their transaction speed—even after sending.
By monitoring network conditions, setting appropriate fees upfront, and knowing how to boost when necessary, you can enjoy faster, more reliable BTC transfers without frustration.
