Bitcoin is becoming more and more popular. The amount of transactions per day is increasing and is at an all times high:. While this is good news, it also has its downsides. Because the size of each mined block is fixed to 1MB, the amount of transactions per block is limited.

There is a lot of debate whether this should be changed. The consequence in the current system is that not all submitted transactions can be processed quickly. The time until a transaction is confirmed can therefore become rather long. Fortunately, the bitcoin network is based on market principles. The invisible hand takes care of this issue: By adding higher processing fees to your transaction you can make sure that it receives higher priority.

It is even possible that it will never get confirmed. Recently, I experienced this case myself. My transaction was stuck for more than 24 hours because my wallet software, Electrum, was outdated. It proposed a way too low fee for the transaction and since I never had to change the default in the past, I just submitted it. After a few electrum wallet unconfirmed bitcoin, I lost my hope that the issue will resolve itself. So I started reading up on solutions and came along quite a few:. For me, only the electrum wallet unconfirmed bitcoin method was practicable and this will often be the case.

I found some pretty decent descriptions of the method here and here. However, applying the method in the practice with Electrum was somewhat tricky. Therefore, I offer a more detailed step electrum wallet unconfirmed bitcoin step how-to here. The basic idea is to create a new transaction which uses part of your unconfirmed transaction as electrum wallet unconfirmed bitcoin input. This transaction should have an elevated fee. For miners to confirm it they will also have to include the previous, unconfirmed transaction into the block.

If the fee of the second transaction is high enough to compensate for both transactions, miners will willingly do this. Just spend some of the received coins or send to yourself with an extra juicy fee. This is because most of the time some amount of the transaction gets back to you as "change".

You can see this by looking at transaction details and checking the outputs. This will take you to the "Send" tab where the "From" field electrum wallet unconfirmed bitcoin includes the correct input. Notice that usually Electrum determines the inputs automatically and hides the "From" field. Otherwise, skip the next step and come back to it after reading on. Go on and enter one of your receiving addresses in the "Pay to" field.

Additionally, make sure to add an appropriate fee for the transaction. This is the crucial part! To determine the fee go to https: Now, find out the combined size of both your transaction. For your unconfirmed one, go back to electrum wallet unconfirmed bitcoin "history" tab and check the "size" field in the details.

For the current one, click the "Preview" button. Add those numbers and multiply by the recommended fee per byte. This gives you a good idea of the total fee you should now enter in Electrum. If there is no field to enter a fee manually but only a slider, make sure to check the "Edit fees manually" box in the preferences.

Sign and broadcast your transaction. Now you know how to resolve unconfirmed transactions with Electrum. As a next step, I recommend to update your wallet software. Most recent versions recommend an appropriate dynamic fee for every transactions.

With that, unconfirmed transactions should be a thing electrum wallet unconfirmed bitcoin the past. Toggle navigation Data Dive. About Alexa Analytics How-to Python.

The Bitcoin network is seriously clogged now, I have had many problems with transactions and maybe you too, if you've set a low fee, it can be stuck in limbo for up to 1 week before being rejected.

But I have quickly figured out how to solve this issue if you have unconfirmed transactions for a long time. Now the RBF should be straightforward, but not all wallets support it, so I am going to show you the hard and long way to fix it, by teaching you how to double-spend a transaction.

The address and wallet shown below is not mine and it's not associated with me at all. I have just picked a random Bitcoin address with an unconfirmed transaction from the memory pool. I have picked a random wallet, and named it RANDOM, it's watch only, but you get the idea, this should be your wallet with an unconfirmed transaction in it. I will demonstrate here how to fix that unconfirmed transaction. You can fix multiple unconfirmed ones too, just by repeating this procedure. We have 1 unconfirmed transaction here, and we need to get rid of it, so here is what you will do:.

Disconnect the Internet, because we will remove this transaction from the wallet, it's unconfirmed so don't worry. Don't reconnect the Internet, because it will re-download it, and you have to start all over again.

Copy the hash of the transaction, by right clicking on it and copy. It should be a SHA hash, the one used in this demonstration is: Open the wallet file with a text editor. The format of the wallet is JSON , so it should be easy to edit if you are familiar with it. It should appear 4 times, in different places, you need to delete them, but carefully to keep the JSON syntax intact, so I have highlighted what you need to delete, it should be different for you, but you will get the idea, it should be everything that is highlighted:.

This is the transaction data section, the TX hash and right below the data should be deleted, as highlighted above. Now, start your Internet, and create a fresh electrum wallet. You have to make a new one to broadcast it, because the other one will get updated as soon as you go online, and it doesn't let us send this way, so you should make a new wallet, but it's just a dummy wallet.

Open the dummy wallet, and load your saved transaction from file. Then just click on the Broadcast button, and you are done! That's it, you are done now, your previous unconfirmed transaction will be cancelled, and it will be overwritten by this new one we created, and with a proper fee, it should get confirmed in no-time! It should cancel in hours if it doesnt go through, but if a node re-broadcasts it accidentally or maliciously, then it can be stuck FOREVER.

I have had my TX stuck for 48 hours, and then some jackass rebroadcasted it, and it was in limbo for more than 72 hours, before I figured out this method and successfully recovered my money with a double spend. This post has been ranked within the top 80 most undervalued posts in the first half of Nov See the full rankings and details in The Daily Tribune: Nov 24 - Part I.

You can also read about some of our methodology, data analysis and technical details in our initial post. If you are the author and would prefer not to receive these comments, simply reply "Stop" to this comment. I was able to follow along and created a dummy wallet but when I hit broadcast I received an error "error: The transaction was rejected by network rules. Does the pay to field in electrum need to be set to the same exact address as the original transaction that had too small a fee?

I did change the address in my example so perhaps that caused the issue? FTR in electrum 2. Might have to remove the 5 command line but as Im not sure what part and not, there's some additional shuffling.. I have 3 transactions unconfirmed now for over 2 days. I am kinda freaking out. Makes no sense there is a backdoor method and not frontdoor. Until a transact actually confirms we could have more EDIT control.

I am using a coinomi wallet ,, not sure how to do this with that. With the RBF you have to enable that flag when sending the transaction, usually enabled by default, so you can replace the TX with a new one.

Otherwise you can use the other methid in which a 2nd transation is sent that increases the cumulative fee for the first one. I did the whole thing but My Electrum wallet still on Watching only mode. I sweeped the PRivate Key but still stuck on that mode. Otherwise I've changed the wallet and deleted those related with my stuck transaction. What's the problem with it? RBF Replace by fee Transaction , if it's supported by your wallet Double-Spend the transaction and put a higher fee manually Now the RBF should be straightforward, but not all wallets support it, so I am going to show you the hard and long way to fix it, by teaching you how to double-spend a transaction.

Don't use the double-spend for chargeback scams! You should only use it to fix your limbo unconfirmed transactions as a last resort! Double Spending First of all you will need Electrum Wallet, because it's easier to edit and configure, so download it, and verify the download signature: We have 1 unconfirmed transaction here, and we need to get rid of it, so here is what you will do: It should appear 4 times, in different places, you need to delete them, but carefully to keep the JSON syntax intact, so I have highlighted what you need to delete, it should be different for you, but you will get the idea, it should be everything that is highlighted: Now open the wallet you should still be offline , and check it it loads.

If it loads then you did a good job. If it doesn't load then you restore the backup and do it again because you probably deleted something that you should have not. The unconfirmed transaction should no longer be there, so that now we can spend it again! Re-create the transaction, but this time put a higher fee: Authors get paid when people like you upvote their post.

So this is a last resort procedure to recover your money. What wallet is working well? Thanks, check out my other articles, all of them are useful imo. How long does this process take? I was having the same problem. Since I posted this article they have added 2 "rescue" methods: Child pays for parent Replace by fee With the RBF you have to enable that flag when sending the transaction, usually enabled by default, so you can replace the TX with a new one.

Look into them and see if your wallet can process that: Thanks child pays for parent worked with heavy fees..
