How to create a multisig transaction without all addresses in the same wallet?

[ThePiachu]

I am wondering - how would I go about creating a multisig transaction for Darkcoin without having all of the keys in one wallet? In Bitcoin I resort to using listunspent data from a block explorer, but I can't find something similar for Darkcoin, plus darkspend might become another hurdle.

What is the process of using multisig with Darkcoin when not all of the keys are in the same wallet?

Welcome to the forum.

Me and fernando did some examples on using multisig in Darkcoin, have a look

here --> http://wiki.darkcoin.qa/display/DRK/Multisignature+example

and

here --> http://wiki.darkcoin.qa/display/DRK/Complex+Multisignature+Example

Hope that helps,
Holger

I guess the approach is similar to what I already had. At the same time, my problem still remains - the system relies on human input to find the unspent transactions, while I would prefer having an automated way to do this. Ideally, it would be using a block explorer with listunspent API, but I can't seem to find any - https://darkcointalk.org/threads/darkcoin-block-explorer-with-listunspent-api.3265/ .

I don't know of any block explorer with an API that allows that. I may be wrong, but I think the only two with a public API are the official one and cryptoID, but they don't offer listunspent:
http://explorer.darkcoin.io/q
https://chainz.cryptoid.info/api.dws

However, in the help page of cryptoID, they say:

The various pages of the site use "undocumented" APIs for their own purpose.
You are free to use them (use, not abuse!), but be aware they can change at any time without notice.

Maybe you can indeed use listunpent with their API and make it work.

If not, the only idea I have is that you use the addmultisig command to add the multisig address to the wallet and then use listunpent in the wallet. I haven't tried this, so I'm not sure if it will work. If you try, please post your results.

If someone can help me get ABE up and running on AWS (I'll pay for the hosting), I would be more than happy to start writing a RESTful API that we can open to the public.

I don't have the Python skills necessary to get ABE running on my own (yet). https://github.com/bitcoin-abe/bitcoin-abe

Send me the pem of the instance, and i'll install it

Thanks flare! May not be until next week, but I'll get a new server setup and send you the pem.

Hey flare, can you fix all the block explorer address prefixes?

multisig starts with '7' now (was '3')
and testnet public keys with 'x/y' (was 'm/n')
and testnet multisig with '8/9' (was '2')

Got it - will update abe code accordingly.
