Hi there,

when will electrum implement the option to reduce fees to 0.00001 btc? It's available since bitcoin core (0.9.0) and I would like to have the choice to use it also with my favorite wallet.

You will have to edit the source code to make this change. Edit the MIN_RELAY_TX_FEE line in lib/bitcoin.py. Change it to 1,000 satoshis:

The reinstall.

thank you
I did try it.
But electrum doesn't propagate a transaction about 0.00079 btc with this fee. It says network can't. With Bitcoin Core (0.9.0) it works

Try connecting to a different electrum server.

The thing is that you need a large portion of the network to be running 0.9.0 for the lower fee to take effect. That means miners but it also means electrum servers for us.

Thank you again. Do you have a tipp which server I should try?

I don't know. You can try asking in the servers thread or the electrum IRC channel about which servers will relay transactions with 1,000 satoshi fees.

I tried several servers by random. None did accept the transaction.

Set the transaction fee in tools > preferences. Then use tools > create transaction > from CSV text to create your transaction. Confirm everything is correct, sign and save the transaction to a file. Then open the file using a text editor, copy the hex portion and broadcast it using bitcoind or blockchain.info's pushtx:

Hmmm ... if I do so (I don't know if I have the knowledge to do) it would be easier to just use bitcoin core ...

I run a bitcoinblog (bitcoinblog.de) and work currently on an article how to lower transaction fees for non-technicals. So I am searching for easy methods to do so

Hmm... for me, all I need to do is set the variable to 0 and it lets me choose any fee...

did you try using 1.9.8?

Ok, I updatet / downloaded the new client.

Still doesn't work.

Did you try to send a tx with 0.00079 btc?

Try the steps I outlined. The problem is server side not client side.

The following electrum servers are running bitcoind v0.9.0

• electrum2.jdubya.info
• jwu42.dyndns.org

But without pools using 0.9.0 it won't matter  ???

Can you explain with example what is the hex portion of file.

They'll probably be treated like no-fee TX by pools who have upgraded to 0.9.0 - at least now they have a chance to propagate where previously they'd only propagate if they matched the strict rules for no-fee tx. It's really experimental at this stage to get them into a block because even bitcoin-qt in core sets the old  0.0001 fee as default to send tx.

It is a plain text file with a json object in it. It will look like this:

You just copy the hexadecimal digits inside the quotes and paste into blockchain.info or eligius' push transaction page. Very simple.
