@l0nelyc0w Checking in. How's it going?

@woodser I managed to get getXmrTxs working with the tests after the problem I had with null values, I followed ProcessModel.java and it helped to get the reply back. I have a question regarding createXmrTx(destinations) though, destinations isn't the only parameter for createXmrTx() right? It should also have the desired amount and the rest of fields that are mandatory to create a tx (as transfer in Monero RPC doc). And relayXmrTx() should take as it's only parameter the tx_metadata created by createXmrTx() (as relayTx in Monero RPC doc).

I think I will have a PR ready within the next 7 days.

@l0nelyc0w The amounts are part of the destinations. The only other required field is the account index which is always 0 for Haveno's wallet, so it doesn't need to be provided.

Yes, relayTxXmr() should take the tx metadata as an argument (I fixed the documentation).

OK account index was the actual field of interest thank you for clarifying.
