Electrum fee under 1 sat/byte

[o_e_l_e_o]

I’m am trying to send Bitcoin through my electrum wallet to my electrum tails wallet and yes they are different wallets not on the same seed.

"TX decode failed" is a Bitcoin Core error message, not an Electrum one. Are you trying to sign a transaction on Electum and broadcast it on Core? Or are you trying to export a partially signed transactions? What version of Electrum are you using? Are you getting some other error message from Electrum?

I’m new to using electrum. I installed the latest version they had and I’m using windows 10. I don’t know what you mean by Core or partially signed. I just followed the YouTube tutorials and other tutorials on how to set it up and it’s not working. No I am not getting any error message from electrum only this. I appreciate the help.

So you go to Send and paste in your address from your Electrum Tails wallet?
You then enter the amount of coin you want to send and hit pay?
You then get a window asking you to set a fee?
You then hit send and get a new window asking you to sign and broadcast the transaction?

Talk us through the steps you are taking and where exactly you get the error message. Also please copy and paste the error message exactly in here.

Electrum servers use bitcoin core to interact with the blockchain so that's why the message is from core.

So how do I fix it?

I can’t send pictures on here but yeah I made a Reddit thread on it. Also maybe the electrum tails address is wrong but I took a picture of it on my phone then sent it it through my email and then downloaded the image to my desktop windows computer and uploaded that image to the send address and I did everything as the following steps as how much I want to send then put the fee but it said it was below the relay some reason then I hit finalize then I signed it and tried to broadcast it and I get the same tx error. I switched servers and tried many things but it not working. I hope I didn’t loose my money it was only about 100 dollars worth of Bitcoin. Still wouldn’t want to loose it.

I think you can only fix it if you have your own full node or ElectrumX server where you can able to edit the minimum relay fee because most of the nodes or servers listed on Electrum only have a relay fee of 1 sat/vbyte lower than that I think no server offers lower than the current minimum fee but you can try to find server under "green circle" change your server and try to send.
Or your last hope is to have an ElectrumX server where you can able to edit the minimum relay fee.

The "TX decode failed" error message below means that the RAW Transaction's structure is incorrect.
The rest of the message is the standard message Electrum shows when failing to broadcast a transaction.

Without the actual RAW transaction or the procedures you've followed, no one can tell what went wrong.
That very long output can't be an address though.

But it seems like you've solved it already?
Based from your reply in Reddit (6 hours ago), you already did.

Based on this comment (https://www.reddit.com/r/Electrum/comments/w4f7s3/tx_decided_failed/ih9vq97/) and the screenshot on that Reddit thread, it looks like OP exported his address as a QR code, saved that QR code as a picture, and then tried to import that actual .jpeg file in to Electrum, which is obviously not how QR codes work. The resulting long string of hex data was obviously not a valid bitcoin address but I think Electrum probably interpreted it as a script, which allowed him to proceed but returned the error when he tried to send coins to it. Once he changed whatever he copied to an address belonging to an exchange, it worked fine.

Which also means, of course, that he wasn't double checking whatever he pasted against the source he copied from (or else he would have realized he didn't copy the address correctly), which means he is a prime target to lose his coins to clipboard malware.

To be fair though, I don't think you can import a QR code that is located inside a computer file on Electrum (CMIIW). It requires a webcam and a second device or a piece of paper.

In the Import screen, there should probably be another option "From QR code" that opens a QR code address, or at least disallow importing from a file whose magic bytes matches that of an image.

Correct. But there should be no need to, really. If you can generate a QR code for an address to import in to Electrum, then you can also just copy the address normally in the first place.

It requires a webcam and a second device or a piece of paper.

Not necessarily. A webcam on its own would suffice, provided it is not built in and so you could there point it at the screen on the same device. Or there are plenty of websites to which you can upload a QR code as an image file and they will decode the QR code for you - whether this is an unacceptable security or privacy risk to you depends on what you are transferring via QR code. (Of course with the caveats of blindly trusting a third party QR decoder and that you should still double check whatever is decoded against the source.)
