Multisig transaction with native assets not working

Question

Hi,

    I am trying to create a multisig transaction with native assets, But I am facing problem at the last, Can you please help me?
    
    I have four nodes, I am listing four nodes address, public key and private below.
    I have created 1000 native assets and sending 100 assets to node and then i would like to test it.
    first three nodes are involved in agreement.
    
    I am getting "error: {"code":-26,"message":"18: bad-txns-inputs-spent"}."

Address                                        Public Key                                                                Private Key

Answer 1

It looks like you forgot to call sendrawtransaction 0100000001c6b3ac... (ea97d7cdac1d1e656e17b93f22c5ae27903e3f96ecb5ab10a6ae5d7c8dd3c23a) to multisig address. That's why you see "complete":false in the output of the subsequent signrawtransaction and error when trying to send transaction relying on non-existent input.

We also strongly recommend using of preparelockunspent API (http://www.multichain.com/developers/json-rpc-api/) for preparing inputs for createrawtransaction. Unlocked outputs can be spent by automatic wallet optimization procedure.
