How to send Unoparty assets in bulk

Below is a script for constructing, signing and broadcasting a large number of sends efficiently. It assumes that the source addresses are in a (temporarily) unlocked Unobtanium Core wallet, to which a running instance of unopartyd is connected.

This script takes a single command-line argument of the CSV file from which to pull the sources, destinations, quantities, assets and fees.

Warning: This example is outdated as it used the previous addrindexrs_uno unobtanium branch, however, same principles apply to current mainline repo.

Script

import csv
import sys

from unopartylib.lib import util
from unopartylib.lib import config
from unopartylib.lib.backend import addrindex_uno

config.BACKEND_URL = 'http://user:password@localhost:4120'
config.BACKEND_SSL_NO_VERIFY = False
config.TESTNET = False
config.REQUESTS_TIMEOUT = 5

def unoparty_api(method, params):
    return util.api(method, params)

def unobtanium_api(method, params):
    return addrindex_uno.rpc(method, params)

def do_send(source, destination, asset, quantity, fee, encoding):
    validateaddress = unobtanium_api('validateaddress', [source])
    assert validateaddress['ismine']
    pubkey = validateaddress['pubkey']
    unsigned_tx = unoparty_api('create_send', {'source': source, 'destination': destination, 'asset': asset, 'quantity': quantity, 'pubkey': pubkey, 'allow_unconfirmed_inputs': True})
    signed_tx = unobtanium_api('signrawtransaction', [unsigned_tx])['hex']
    tx_hash = unobtanium_api('sendrawtransaction', [signed_tx])
    return tx_hash


with open(sys.argv[1], 'r') as csvfile:
      reader = csv.reader(csvfile)
      print('{}|{}|{}'.format('linenum', 'input', 'result'))

      for row in reader:
            if reader.line_num == 1:                                            
                  continue                                                        

            source, destination, asset, quantity, fee = row
            fee, quantity = int(fee), int(quantity)

            try:
                  tx_hash = do_send(source, destination, asset, quantity, fee, 'opreturn')
            except Exception as e:
                  tx_hash = str(e)

            print('{}|{}|{}'.format(reader.line_num, ','.join(row), tx_hash))

CSV File

All quantities are specified in satoshis. The format of the CSV file is as follows:

source,destination,asset,quantity,fee
  uVVuwXm2mDK9pr9XkWT5k7ihQyoSC8y2MW,uVVuwXm2mDK9pr9XkWT5k7ihQyoSC8y2MW,XUP,100000000,150
  uVVuwXm2mDK9pr9XkWT5k7ihQyoSC8y2MW,uVVuwXm2mDK9pr9XkWT5k7ihQyoSC8y2MW,XUP,200000000,100

Instructions

Use this script on a system with unoparty-lib installed and in the PYTHONPATH. (If using a Federated Node, this is possible by issuing the command unonode shell unoparty or unonode shell unoparty-testnet as appropriate, and using the script in that shell.)

If the CSV file with the data is called input.csv, and the script is called sendmany.py, then call this script with $ python3 sendmany.py input.csv.
