Key Points:
Bitcoin transactions can take anywhere from one minute to several hours to confirm, depending on network congestion. The good news is that there are multiple ways to speed up Bitcoin transactions in 2025.
As Bitcoin becomes more popular and more people use it as a payment method, addressing Bitcoin transaction issues will help you secure the next block to confirm your transaction.
There are now more solutions available to address pending Bitcoin transactions. These solutions are easy to implement and can provide you with peace of mind.
Recent technological advancements allow users to add higher fees to transactions even after sending payments.
In 2025, Bitcoin will continue to evolve as a new global store of value and decentralized currency system, leading to more frequent transactions. Therefore, Bitcoin's limited block space of 4MB may result in ongoing network congestion and Bitcoin transaction confirmation issues, causing users' payments to be delayed for hours or even days.
Fortunately, Bitcoin holders can use several methods to address blockchain transaction delays, especially during periods of congestion that may delay or even cancel timely payments.
Setting appropriate fees before sending transactions will help users manage their Bitcoin transactions with ease.
This article serves as a guide to resolving Bitcoin transaction bottlenecks. It will help you speed up pending BTC payments and provide step-by-step guidance for fixing Bitcoin transactions.
How do Bitcoin transactions work?
Bitcoin transactions allow network participants to transfer value to recipients using wallets. When someone initiates a Bitcoin transaction, they broadcast it to all network nodes. These nodes maintain a complete history of the blockchain, including all unconfirmed transactions waiting for the network to add them to the next block.
Unconfirmed transactions eventually enter the memory pool, which is a temporary storage space or queue for pending transactions. A transaction is only confirmed when a miner adds it to a block and removes it from the memory pool.
Understanding Transaction Fees in 2025
When users initiate a BTC transaction, they pay network fees to miners for verifying the payment and adding it to the blockchain. Miners are individuals or businesses that need to make a profit, earning income by generating new Bitcoins.
They also maximize their returns through users' fees, so they will prioritize transactions with higher fees, removing them from the memory pool and adding them to the next block.
However, Bitcoin's block space can only accommodate a limited number of transactions, depending on the size of the data being transmitted. High network congestion will lead to delayed confirmations for low-fee transactions, which must wait until their priority is higher than other payments to be added to the next block.
Why do Bitcoin transactions get stuck?
Wallets typically set the optimal transaction fee based on current network traffic. If users need a quick resolution, they can set a custom fee to speed up the transaction. The higher the fee they pay, the faster the transaction confirmation.
That said, sudden spikes in network congestion can delay Bitcoin payments. Additionally, low fees will significantly increase wait times. Paying the minimum fee often places transactions at the back of the queue, potentially causing them to get stuck in a pending state.
This situation will persist until unconfirmed payments in the memory pool are resolved, network congestion eases, and the fees for the payments are acceptable enough for miners to include them in the next block.
Did you know? Community or miner-operated Bitcoin transaction accelerators can manually prioritize stuck transactions for inclusion in the next block by charging a fee. This is particularly useful during periods of network congestion.
Check Your Bitcoin Transaction Status
All Bitcoin transactions are published in the memory pool. Miners only remove and confirm transactions from the memory pool when they add them to a block.
Stuck transactions may remain in a pending state indefinitely, while those with the lowest fees may even linger in the memory pool permanently, although typically not for more than a few days. When this happens, the funds will be returned to the sender's wallet, which can then send a new transaction. A higher fee may lead to faster payment confirmation.
Bitcoin users can check the status of their transactions through various available blockchain explorers, including Mempool.space. Here, the paid transaction fees can even be compared with the existing rates displayed. This helps check if the transaction is stuck due to low fees.
How to Use a Block Explorer to Find Unconfirmed Bitcoin Transactions?
All block explorers have a search field where you can enter the transaction ID or wallet address. The transaction ID is usually a long string of letters and numbers.
Depending on the explorer tool you use, the information may be displayed differently. Clicking on it usually reveals details such as confirmation count, addresses, the amount of Bitcoin sent, fees, and timestamps.
To check the transaction status, follow these steps:
Choose a reliable block explorer, such as Mempool.
Look for the provided search box on the homepage.
Enter the transaction ID. The results will display basic details of your transaction.
If your transaction is still pending, it will show as "unconfirmed" and will display the estimated block for confirming the transaction. If there is no estimated block, it means the fee is too low, effectively causing the transaction to get stuck for a while.
How to Fix Bitcoin Transaction Delays
There are many valuable tips to avoid Bitcoin transactions getting stuck. Before that, you should consider these questions: How urgent is your Bitcoin transaction? Are you prepared to pay a higher fee to resolve it faster?
If you do not have an urgent payment need, you can simply initiate the transaction and wait for confirmation. There will be no loss of funds; in the worst-case scenario, if the transaction is not confirmed, the funds will return to your wallet.
To avoid stress during periods of network congestion, you can set a higher transaction fee. This will ensure that your transaction is added to the next block and confirmed quickly.
Here is a step-by-step guide to help you deal with stuck Bitcoin transactions and confirm them faster.
Step 1: How to Use "Replace-By-Fee" to Fix Stuck Transactions?
If your transaction has already started and you did not increase the miner fee, it may get stuck in the memory pool due to congestion. What can you do in this case?
Yes, you can still use a tool called Replace-By-Fee (RBF) to skip the queue. It allows you to rebroadcast the same unconfirmed transaction with a higher fee. This increases the chances of miners choosing it and adding it to the next block.
RBF has several variants, but a good option is Opt-in RBF. It allows the sender to indicate that they want to replace their low-fee transaction with a higher-fee one in case it gets stuck in congestion.
In most cases, you must enable the Opt-in RBF option in your settings before sending the transaction. This is important to avoid nodes thinking it is a fraudulent double spend and rejecting the replacement transaction.
Step 2: Use "Child Pays for Parent" to Clear Stuck Transactions
If your wallet does not provide the Opt-in RBF tool, there is another option to help you confirm transactions faster.
It is called "Child Pays for Parent" (CPFP). It allows users to spend outputs from a low-fee unconfirmed transaction ("parent" transaction). The new transaction ("child" transaction) will have a higher fee rate, incentivizing miners to choose both transactions and add them to the next block.
Before sending a new transaction, check your wallet to see if it supports either or both of the Replace-By-Fee and Child Pays for Parent options. Not all miners or wallets allow the use of these tools.
Step 3: Use Mining Pools to Accelerate Your Bitcoin Transactions
Several mining pools offer "transaction accelerators" through third-party services like Mempool or ViaBTC. By entering the ID in the relevant search bar, you can accelerate stuck transactions with at least 0.1 mBTC fee per kilobyte. Participating mining pools will prioritize processing it over other transactions. The service is free but limited to 100 transactions per hour.
Mempool accelerators allow users to pay fees via Lightning or Cash App to speed up their pending Bitcoin transactions.
Did you know? CPFP was conceived by Bitcoin developers to address low-fee transaction issues, enabling users to accelerate confirmations by incentivizing miners with higher fees in subsequent transactions.
Prevent Future Bitcoin Transaction Bottlenecks
Assessing the urgency of payments is the first step in setting appropriate rates. During high network congestion or price volatility, users can set custom fees. This ensures their transactions are confirmed quickly and do not get stuck or rejected.
Remember, even if you have already sent a transaction, you can easily accelerate it using RBF or CPFP. Check your wallet to see if these tools are available. If these options are not available, wait for the transaction to confirm. If it gets canceled, resend it after checking network congestion.
