Hi,
when trying to use publishmulti with multichain 2.0 beta:
{"method" : "publishmulti", "params":["myStream1", [{"key":"k1","data":"0123"},{"key":"k1","data":"0123"}]]}
I get:
{
    "result": null,
    "error": {
        "code": -25,
        "message": "Transaction was not signed properly"
    },
    "id": null
Do I have to sign the tx? I thought you have to do it only for raw tx.
Thanks!
