Now that you know how the system works, you can understand what really happens with unconfirmed Bitcoin transactions. A Bitcoin transaction can only belong to 1 of the following 3 statuses: confirmed, unconfirmed, or rejected. We know what a confirmed transaction is. Unconfirmed transactions, therefore, are transactions waiting to be confirmed.

Most of the time what this means is that they are waiting to be picked up by miners, confirmed on the blockchain, and have this process happen enough times for vendors or receivers to deem it valid. Transactions with zero confirmations remain in the mempool waiting to be picked up by miners. This usually happens because miners select which transactions to prioritize based on the transaction fee. If transaction fees are too low, miners are not incentivized to process and confirm or reject them; they are not getting paid enough to do so.

Unconfirmed transactions can remain in the mempool indefinitely until eventually they are picked up and confirmed or rejected by a miner. Users can push unconfirmed transactions, or transactions with zero confirmations through the mempool, using 1 of the following 3 methods:. Those are, in simple terms, the inner workings of the Bitcoin transaction confirmation mechanism. Hopefully, the information here will allow you to understand what happens with unconfirmed Bitcoin transactions and how to push your transactions through.

It should also allow you to understand how to prioritize your transactions to save on transaction fees. Think about the following technique, based on the information above:. By Bitcoin Chaser. Share this article. Keep in mind that in order to take advantage of this, you need a proper bitcoin wallet which allows for custom fee setting. A selection of such wallets you can find here or here. Here you can see a visualization of how many unconfirmed transactions are currently on the network, as well as how many were there in the past.

Each coloured layer represents a different fee amount. The most interesting graph is the third one, which shows you the size of the current mempool in MB and the amount of transactions with different fee levels, which would compete with your transaction if you were to send it right now. But this also should help you to see that even the low fee transactions get confirmed very regularly, especially on weekends and in the night periods, and that the spikes in the mempool so far have always been temporary.

For that you can switch to higher timeframes in the upper right corner, f. Try higher timerframes as well. You clearly can see that the mempool is cyclical and you can set a very low fee if you are not in hurry. This is also an overview of the current mempool status, although less visual than the previous one.

It shows you some important stats, like the mempool size, some basic stats of the recent blocks tx fees, size etc. You can see this projection in the left upper corner the blocks coloured in brown. This is a simple estimation tool. It is very simple to use, but the disadvantage is that it shows you estimates only for the next 24 hours. You probably will overpay by this method if your transaction is less time sensitive than that. This is a very simple bot that tweets out fees projections every hour or so.

Very simple to use. Hopefully one of these tools will help you save fees for your next bitcoin transaction. Or at least help you understand that even with a very low fee setting your transaction will be confirmed sooner or later. Furthermore, I hope it makes you understand how important it is to use a wallet that allows you to set your own fees.

There is currently a backlog of unconfirmed Bitcoin transactions and typically only the transactions with the highest fees will be confirmed until the backlog clears. Sign up to join this community.

Add a comment. Active Oldest Votes. How Bitcoin Mining Works Bitcoin transactions are mined processed by Miners, and Miners want to benefit from their work. If you have sent a transaction without or with an exceptionally small transaction fee expect it to be ignored for an unknown amount of time until a miner decides to process it and solves the block; this could be several days to several weeks, possibly never.

The next best thing is to cancel and resend the transaction. Make a note of the individual bitcoin address es that the unconfirmed transaction was sent from. Run Bitcoin Core with the -zapwallettxes option or wait a few days until your wallet stops broadcasting the transaction and it falls out of the global transaction mempool. Issue with mempool. Send all your bitcoins from the addresses recorded in step 1 to a new address with the recommended or higher than recommended fee.

Make original transaction again using the recommended fee. What to watch out for Sites that claim to "speed up your unconfirmed bitcoin transaction". If the addresses used in the original transaction have sufficient bitcoin in them to cover the transaction, it can always be completed at a later date. To avoid this, follow step 3 to empty the associated addresses and do not reuse them.

AntonKrouglov: That sounds like a bug. Please file an issue on github. Update: There is an issue already: github. I agree except for "your transaction is stuck in limbo". The wallet may say "unconfirmed transaction" and it may show a different balance as if the transaction was actually confirmed but the network itself agrees on the fact that you transaction did not take place.

The "limbo" is the danger to be in a double spending scenario, aka during the first 1 or 2 confirmations — Gianluca Ghettini. GianlucaGhettini "limbo" means "an uncertain period of awaiting a decision or resolution; an intermediate state or condition". Since the transaction is awaiting inclusion in a block, limbo describes the situation well.

Once a transaction is broadcast I would say it is in limbo as long as it is valid, even if it is no longer in any public mempools. The only resolutions are to confirm or invalidate by double spending the transaction.

Double spending is not a danger in this situation because you are the sender, not the receiver. Show 6 more comments. This makes the wallet "forget" any unconfirmed transactions, thus enabling you to reuse their inputs. Create a new transaction to make your payment and add an appropriate fee this time. The simplest way is to send all your bitcoins to yourself. Steve Ellis Steve Ellis 1, 8 8 silver badges 10 10 bronze badges. This is a far better option than the accepted answer.

Helped me a lot. A bit more detailed explanation can be found here: reddit. How are they caused? What can I do to make my stuck transaction confirm? There are several options for confirming stuck transactions: For both the recipient and the sender of the transaction, you can: Wait for the transaction to confirm Wait for the network to "forget" about the transaction Ask a miner to confirm it for you For the sender of a transaction, you can also: Attempt an Replace-By-Fee double spend transaction If you have a change output, you can attempt a Child-Pays-For-Parent transaction For the recipient of a transaction, you can also: Attempt a Child-Pays-For-Parent transaction Waiting for a confirmation If you are incapable of performing any of the other options or are too afraid to do so, you can simply wait and hope that the transaction will eventually confirm.

Waiting for the network to "forget" about the transaction If a transaction remains unconfirmed for too long, it can be eventually "forgotten" by most nodes on the Bitcoin network if no one rebroadcasts the transaction. Ask a miner for help Some mining pools and miners offer services to allow you to prioritize your transaction in their mempool so that it is chosen sooner for inclusion in a block. How can I avoid making Stuck transactions in the future? Using Dynamic Fees The best way to avoid having stuck transactions is to make sure that you are not spending from an unconfirmed transaction, and include a sufficient transaction fee.

Armory Armory also allows for the creation of RBF transactions. I just experienced a "gotcha" in Bitcoin Core 0. The transaction required no "change" address since it was spending exactly the amount of the input. When attempting an RBF to speed up the transaction, bitcoin-qt complains that there is no change address present in the transaction, so RBF cannot be used.

MaxVernon, see my question exactly about this issue: bitcoin. Rebroad Why not? The mempool. When you start again, everything that was there is loaded into the mempool again. By deleting this file, the mempool will start out empty without your transaction so it can be abandoned. Then, you can resend the transaction with a higher fee. Is this also the answer to bitcoin. Adam Adam 3, 1 1 gold badge 11 11 silver badges 33 33 bronze badges. ViaBTC recently stated that their allotment for an hour is used up in about 3 minutes.

TL;DR: Your funds are safe. A transaction either will be confirmed or it never leaves your wallet, so there is nothing to worry about in regards to the safety of your coins. How is the speed of confirmations determined in bitcoin? So what happens if my transaction stays unconfirmed for days or even weeks?

The order here is roughly from advanced to easy. Any Help???? You have a few options: Submit your transaction to the ViaBTC Transaction Accelerator If you control either of the receiving addresses, send a new transaction from one of them with a much larger fee, encouraging a miner to pick up the whole chain of transactions Child-Pays-For-Parent. The transaction should be either confirmed or removed from the memory pool within about 72 hours.

It is important to note that a Bitcoin user cannot undo a confirmed Bitcoin transaction ; however, an unconfirmed Bitcoin transaction can be cancelled. If the blockchain does not approve a Bitcoin transaction within 24 hours , it is considered unconfirmed.

Every transaction must be confirmed by a miner via the proof-of-work principles. A transaction must receive at least three confirmations before it can be completely approved by the blockchain. If a Bitcoin transaction is still recent less than 5 minutes , it can be canceled or unconfirmed, and if that happens, the user may have to wait longer for confirmation, as even the fastest network requires at least 10 minutes to confirm a transaction.

A Bitcoin transaction can also be unconfirmed if the transaction fee is too low or not included. According to the cryptography of Bitcoin, smaller transaction sums have a lesser likelihood of being confirmed successfully. Miners may refuse to confirm transactions with excessively low fees. However, if your transaction is not verified by the network within 24 hours, you can reverse it.

But be certain that the transaction is indeed unconfirmed. Since the blockchain is open to the public, you can simply keep tabs on your transaction. To track a transaction with the block explorer , all you need to do is input the transaction ID. All Bitcoin transaction requires at least three confirmations to be deemed successful. If your transaction has two or one approval, it must be validated by a third miner.

The RBF Protocol allows you to broadcast a Bitcoin transaction to the whole network a second time for a higher fee. As a result, miners can select the transaction quickly, cancelling the previous transaction and initiating a new one.

As a result, first, check to see if your wallet permits you to do so. When transferring Bitcoins, you can choose this option to ensure that you can utilize it if required. However, if your wallet does not support the RBF Protocol, you can utilize the higher-fee double-spend option. Many people transacting over the Bitcoin network implies that the blockspace is in popular demand, meaning that when you send a transaction, it has to compete with other transactions for the inclusion in one of the blocks in the future.

Miners are motivated by profits and transactions that pay more than other transactions are preferred when mining a new block. This post attempts to explain how the mempool works, how to optimize fees and that one does not need to worry about their funds.

In bitcoin there is no "in transit". There is no situation where they "leave" one wallet and are not simultaneously and instantaneously in the destination address. If that is the case, you just wait. Eventually the transaction will either happen or will be deleted by the network.

Keep also in mind that this is not possible with any transaction RBF requires opt in before sending, f. If nothing else works and your transaction really needs a soon confirmation, you can try and contact a mining pool to ask them if they would include your transaction. Some mining pools even offer a web-interface for this: 1 , 2. If you are interested in trying out those options, here is a very helpful post that goes more into it: What can I do to make my stuck transaction confirm?

Here you see how many transactions are currently and were historically waiting to be confirmed, i. You can then deduct which layer your own transaction is currently at, and how far away from the top your position is miners work through the mempool always from the top, simply because the transactions on top pay them more. You can estimate that each newly mined block removes 1MB from the top see the third graph which shows the mempool size in MB. On average, a new block is produced every ten minutes.

The second important observation is that the mempool "ebbs and flows", so even the lower paid transactions are periodically being confirmed at some point. A you can influence directly, B you can observe in real time, but C is difficult to predict. Good to know : "fee" means the absolute amount of satoshis a transaction pays, and "fee rate" is the fee per weight of a transaction. Miners prioritize by the latter, because even if a "lighter" transaction pays less in absolute satoshis, it might be more profitable to include it into a block if it has higher fee rate, because it also takes up less space.

Transactions are being broadcast by the full nodes on the network. Each node can adjust their settings for how long they keep unconfirmed transactions in their mempool. This means that in the absolute worst case the unconfirmed transaction will simply disappear from the network, as if it never happened.

Keep in mind that in those two weeks the coins never actually leave your wallet. A transaction with very low fee rate might also disappear from the network if the mempool goes over MB in size, because by default a Bitcoin Core node will purge transactions from its internal mempool, starting with the lowest fee rates first, while increasing its minimum acceptable fee rates that it will broadcast further. You can read more about it here. Keep in mind that in order to take advantage of this, you need a proper bitcoin wallet which allows for custom fee setting.

A selection of such wallets you can find here or here. Here you can see a visualization of how many unconfirmed transactions are currently on the network, as well as how many were there in the past.
