Title: Cosigner pool
Post by: dave111223 on February 02, 2015, 03:24:58 AM
Where can I get more details on how to use the co-signer pool?

I have taken the following steps (in 2.0 beta):

1) Setup a single-sig wallet
2) Used the master pub key (from #1) to setup a 2of2 multi-sign wallet
3) Turned on co-signer pool plugin in my multisig wallet
4) Created a send transaction in my multisig wallet and clicked "Send to co-signer"
5) Open single-sig wallet and tried to turn on the co-signer pool plugin but cannot because it is greyed out

So how can I sign the 2nd signature via the pool using my single-sig wallet?

This is not the way you are supposed to create a multisig wallet.
You need to create two multisig wallets files, A and B, where A has the xpub of B, and B has the xpub of A
See the doc here: https://electrum.orain.org/wiki/Multisig_Wallets

Before you do anything else, you need to recover the coins you sent to the 2 of 2 wallet you created.
For this, create a new wallet file, select 'restore' and 'multisig 2of2'
Then enter the two seeds in the dialog box. (the seed of the standard wallet, and the seed of the 2of2 wallet you just created)

please report back here.
it may be that the multisig wallet creation procedure is too difficult for most people.
in any case I think we will have to improve it.

Oh ok I get it now, thanks.

P.S. I was still able to use my multisig + singlesig wallet.  But I had to "Save" the signed transaction from the multisig wallet and import into the singlesig wallet, and it worked, without any need to do a wallet restoration.
