Electrum: send transactions status Unconfirmed after 12 hours

[nelson4lov]

OP, as a rule of thumb, before making any future BTC BTC transaction, ensure you have gone to https://mempool.space  to get the current fee rate. I failed to do so two weeks ago and my transaction was unconfirmed for almost a week. Good thing Electrum RBF feature is enabled by default — I was able to bump the fee. I'm saying this because some wallet providers like Mycelium wallet fee suggestions are confusing but a tool like mempool.space streamlines the process.

I am surprised that you somehow managed to get a transaction with a fee so low to even broadcast. I used to use via BTC and I used 10 sat/byte and I almost never could get the transaction broadcasted by electrum. I had to manually go to a block explorer and broadcast the raw transaction there. The fact that you managed to get one being 1sat is very surprising.

Just need to right click on the transaction in electrum, and click Increase fee and use 40-50 sat instead of 1 and it’ll confirm in a few hours. Keep in mind if you don’t have RBF enabled then you will have to wait for it to drop it from the mempool or do CPFP but I don’t think that is necessary in this case. Try and increase fee first and if you get an error let us know and we will do CPFP instead.

@hosseinimr93 and @o_e_l_e_o:
What if:
1. I remove the local transaction from the sending wallet
2. I spend all the coins
3. Can later one of the nodes which has my transaction actually complete it? If yes, then what happens?

If the second transaction is confirmed then the previous one will become invalidated and will be removed from the mempool.

Then you may wonder what if both the TXs included in the same block, like I did and here is why it will never happen explained by o_e_l_e_o

If both transactions are valid then both transactions can be included in the same block too if the fee is used in the same range then what happens?

The default behavior of a node is never have two or more conflicting transactions in its mempool. When it accepts a replacement, it evicts the original. As such, it would never create a candidate block which contains two conflicting transactions. Should some mining pool edit their software and accidentally mine a block containing conflicting transactions, all other nodes on the network would reject it as being invalid.

Well I did make a mistake like that in this last month. I did not send enough fees and I was having to wait 3 days for my Bitcoin confirmation.
Just make sure you check the meme pool if you do not want that to happen. There is many things going on now with the Bitcoin network and we must pay more then used to for transactions.

Bitcoin fees were huge this week with several of transactions pending. The congestion seems to be easing today but not sure if there would still be another spike.
Average fees has decreased below $10, which is still large. Considering the corrective price, we could get a smooth mempool this week. If you are not in a hurry you could wait for the congestion to ease. I check the current average fees before broadcasting a transaction from my wallet.

Being a novice, this is all an untouched territory for me. I signed up for mempool.space, I learned how to see my transaction and its ETA. How do I find fees?

You don't need an account - just go to https://mempool.space/ and look at the left side of the screen for the section on transaction fees, and pick an appropriate fee.

If you want to get a bit more complex, then try looking at https://jochen-hoenicke.de/queue/#1,8h. This site shows you a graphical representation of the mempool, which each colored band representing transactions of a given fee. Knowing that each block will remove roughly 1 vMB of transactions from the top of the mempool, you can choose exactly where you want to place your transaction in the mempool and the appropriate fee rate to do so.
