Creating raw trasactions offline using pybitcointools.

Question

Ok, so I'm trying to create the raw transaction offline using this python lib:

https://github.com/vbuterin/pybitcointools/blob/master/bitcoin/transaction.py

For bitcoin tx I'm feeding the serialiser the following to create the Tx hexstring:

{'locktime': 0, 'version': 1,
    'outs':
        [{
            'value': 990000, 'script': 'a914cf17f42454bb7e9159a99de401eb188c129d701487',
    'ins': [{'sequence': 4294967295, 'outpoint': {'index': 0, 'hash': '45b1314a725432a6121a52798ed5e5882c99407d2dd8eef9174a2dc7e6c180cd'}, 'script': ''}]}

 

what is the multichain network expecting the value to be in order to transact assets and native currency?

 

Something like

{"":3, "bankpoints":12.0}} ??

Answer 1

You need to express any assets as OP_DROP metadata inside the output script. The format is fully documented here and you can also use createrawtransaction to see some examples.

Thanks for the reply.

I undertand the problem then is in the library. is there any multichain-compatible library to work with multichain, or a fork of the pybitcointools with supports the multichain?

Not, yet - no. But you always have the option of using MultiChain's createrawtransaction API to build the transaction.
