How to make a bitcoin transaction and pay less than 1 sat/vByte

You may have to add information to click the use SSL button, because I got an error when I didn't.

What kind of "information" did you need to add?

I've succeeded in changing after I clicked the Use SSL button.

I don't remember having to click on "Use SSL" when I tested this on my own setup back when I was writing this thread. Maybe it was already turned on from before or the software did it by itself after a restart. I also don't remember seeing error messages.

I see what happened here:
He must have disabled that "Use SSL" switch beforehand (from his old settings or something else) that's why he had to enable it when he followed your instructions.

On the other hand (at your end);
You do not remember having to tick that settings and your test worked right away because it's switched-on by default.

Including a short note should prevent rare instances like this.

Are you saying that I should mention something in my OP about the Use SSL option and how it should be ticked for network changes to be recorded properly? I could add that somewhere in the tutorial.
Or perhaps you were trying to say that it should have been noted by Blue Wallet in the network settings tab?

Something like: 'Make sure that "Use SSL" is ticked' in the OP about BlueWallet should be enough.
It's switched-on by default, but in cases like what happened to "@Not your key not your BTC", the note should prevent it.

Pmalek, since version 4.6.2 of Electrum, you no longer need to use the wallet.relayfee=(lambda: 0) command, and all you need is to be connected to a server that accepts transactions with a fee rate of less than 1 sat/vbyte.
I noticed this after SeriouslyGiveaway shared a link to your topic in another thread thinking that it's difficult to make such transactions using Electrum.

You may want to consider editing the topic, so that it reflects the changes that have made it easier to make sub 1 sat/vbyte transactions in more recent versions of Electrum.

That's great, if only the newer executable versions & even the Python sources install of Electrum didn't have minimum system requirements (PyQt6 binary wheel dependency on non-backward-compatible system frameworks and dynamic library symbols) above what some of us actually have.

I can only run Electrum 4.8.2 bypassing the GUI entirely and using TUI/text mode (-g text) or headless daemon commands, and I had to go through hell installing everything that should have been, but wasn't, done automatically by the first or second command after downloading the .tar.gz Python sources file.

Now, I don't want to get off on a rant here, but...

It is because you are using desktop Electrum for transactions will be the reason you did not know early. It was also not possible on mobile Electrum before, but version 4.7.0 supported it, the time it also supported fee customization. So far you connected to the node that is supporting it, the transaction will be sent.

I feel like you didn't get my point, or maybe I didn't get yours. I already knew about making sub 1 sat/vbyte transactions in Electrum.

Before Electrum 4.6.2, you needed to do two things to make a transaction with a fee rate of less than 1 sat/vbytes. One was to use the wallet.relayfee=(lambda: 0) command, and the other was to connect to a server that accepts sub 1 sat/vbytes transactions.

Now, it's much easier.
You no longer need to use the console, and all you need is to be connected to a server that accepts such transactions. Currently, even if Electrum connects to a server automatically or you choose a random server, there's a good chance that the server will broadcast your transaction.

I suggested editing the topic, so that someone without much technical knowledge who reads the guide doesn't get the impression that it's difficult to make a sub 1 sat/vbyte transaction in Electrum.
As I said, the suggestion came to my mind after reading this post in another thread.

I think he's just adding a note about when it's implement on the Android version of Electrum
but somehow made his post look like going against yours due to the words that he's used, specially that first part.

That's great to know and thanks for pointing it out. I didn't know Electrum made that change and simplified the sending of sub 1 sat/vByte transactions. I will edit my OP and mention it. Charles-Tim's post isn't clear. Do you know if sub 1 sat/vByte transactions are supported on Electrum's mobile app or not?

[hosemary]

Yes, it allows you to set the fee rate manually and make sub 1 sat/vbytes transactions since the version 4.7.0. Now like the desktop version, all you need for making such transactions is to be connected to a server that accepts them.

From Electrum's Release notes:

  - new: allow manual editing of fee/feerate (#10371)
          This also allows sending sub-1 sat/b transactions on Android.

The electrum servers recommended in this guide are not showing on the list of available servers on my electrum. When I copy and past the name of one of those servers into the "server" field, it doesn't change to that server. Is there another one I can look for that accepts low fees? I haven't found one yet. I'm running version 4.5.4, in case that might be an issue.

Try mine on "Manual server selection", including port number:

I'm currently installing my very first Electrum server electrum.loyce.club:50002

I'm running version 4.5.4, in case that might be an issue.

You may want to upgrade to make low fees easier.

Since Electrum version 4.6.2, it's no longer necessary to use the wallet.relayfee=(lambda: 0) command.

It's no longer like it was in the early days and there are many servers that accept sub 1 sat/vbyte transactions. This means that you should be able to find a server that supports such transactions easily.
Even if you let Electrum connect to a server automatically, there's a good chance that it will accept your transaction.

The electrum servers recommended in this guide are not showing on the list of available servers on my electrum.

This can occasionally happen since all available Electrum servers aren't hard-coded internally.

There are only a couple of servers that's pre-included to the list: github.com/spesmilo/electrum/blob/master/electrum/chains/mainnet/servers.json
Then, the rest should appear after they are fetched from the available servers if those are connected to them.

When I copy and past the name of one of those servers into the "server" field, it doesn't change to that server.

Manual server selection shouldn't have any issue.
It's either your network has issue connecting to it or it's (temporarily) offline.

Thanks for the replies. I found a server that is working with low fees. I don't see any reason to update my electrum at this time, because I've already added the line for low fees in the terminal.

The last two times that I tried to connect to "electrum.labrie.ca" it didn't work and the server was offline. I don't know what the status of it is today. If you couldn't connect to it either, maybe it's been shut down. LoyceV server worked when I needed it, though.

Just know that if you are planning to use the "wallet.relayfee=(lambda: 0)" command, it's something you have to enter into the console every time you load Electrum and want to make a sub 1 sat/vByte transaction. It's not a one-time thing. Alternatively, you can also use the plugin by TryNinja that runs the command whenever you open Electrum. Still, the easiest thing to do is to just update the software to the newest version.
