• Python 3.6+ support

Installation

pip3 install moneyonchain

or with specific version

pip3 install moneyonchain==2.0.0

Usage

Network manager

Network manager manage connection to node and other specific to current connected network. By default if you run the first time .install(), this will install current used networks of our enviroments by brownie.

First time you are going to interect with our api you will need to install predefined connections networks

from moneyonchain.networks import NetworkManager

connection_network='rskTesnetPublic'
config_network = 'mocTestnet'

# init network manager
# connection network is the brownie connection network
# config network is our enviroment we want to connect
network_manager = NetworkManager(
    connection_network=connection_network,
    config_network=config_network)

# run install() if is the first time and you want to install
# networks connection from brownie
network_manager.install()

Connection table

Network Name	Network node	Host	Chain
rskTesnetPublic	RSK Testnet Public	https://public-node.testnet.rsk.co	31
rskTesnetLocal	RSK Testnet Local	http://localhost:4444	31
rskMainnetPublic	RSK Mainnet Public	https://public-node.rsk.co	30
rskMainnetLocal	RSK Mainnet Local	http://localhost:4444	30

Example 1. Connect by default to RSK Testnet public node and to mocTestnet enviroment and print is connected

from moneyonchain.networks import NetworkManager


connection_network='rskTesnetPublic'
config_network = 'mocTestnet'

# init network manager
# connection network is the brownie connection network
# config network is our enviroment we want to connect
network_manager = NetworkManager(
    connection_network=connection_network,
    config_network=config_network)

# run install() if is the first time and you want to install
# networks connection from brownie
# network_manager.install()

# Connect to network
network_manager.connect()

print(network_manager.is_connected())

# finally disconnect from network
network_manager.disconnect()

Price provider

Get the last price from MOC or RDOC contract.

See example in source/example/price_provider.py

from moneyonchain.networks import NetworkManager
from moneyonchain.oracle import PriceProvider

import logging
import logging.config

# logging module
# Initialize you log configuration using the base class
logging.basicConfig(level=logging.INFO)
# Retrieve the logger instance
log = logging.getLogger()

connection_network='rskTesnetPublic'
config_network = 'mocTestnet'

# init network manager
# connection network is the brownie connection network
# config network is our enviroment we want to connect
network_manager = NetworkManager(
    connection_network=connection_network,
    config_network=config_network)

# run install() if is the first time and you want to install
# networks connection from brownie
# network_manager.install()

# Connect to network
network_manager.connect()

price_provider = PriceProvider(network_manager)

log.info("Last price: {0}".format(price_provider.price()))

# finally disconnect from network
network_manager.disconnect()

result:

INFO:root:Connecting to mocTestnet...
INFO:root:Connected: True
INFO:root:Last price: 10725.4

RDOC Contract:

from moneyonchain.networks import NetworkManager
from moneyonchain.oracle import PriceProvider

import logging
import logging.config

# logging module
# Initialize you log configuration using the base class
logging.basicConfig(level=logging.INFO)
# Retrieve the logger instance
log = logging.getLogger()

connection_network='rskTesnetPublic'
config_network = 'rdocTestnet'

# init network manager
# connection network is the brownie connection network
# config network is our enviroment we want to connect
network_manager = NetworkManager(
    connection_network=connection_network,
    config_network=config_network)

# run install() if is the first time and you want to install
# networks connection from brownie
# network_manager.install()

# Connect to network
network_manager.connect()

price_provider = PriceProvider(network_manager)

log.info("Last price: {0}".format(price_provider.price()))

# finally disconnect from network
network_manager.disconnect()

Result:

INFO:root:Connecting to rdocTestnet...
INFO:root:Connected: True
INFO:root:Last price: 0.092123288999999996

Mint BPro example

To run this script need private key, where replace with your PK in PRIVATE_KEY, and also you need to have funds in this account

martin@martin-desktop:~$ export ACCOUNT_PK_SECRET=PRIVATE_KEY
martin@martin-desktop:~$ python ./mint_bpro.py

Example code

from decimal import Decimal
from moneyonchain.networks import NetworkManager
from moneyonchain.moc import MoC

connection_network = 'rskTesnetPublic'
config_network = 'mocTestnet'

# init network manager
# connection network is the brownie connection network
# config network is our enviroment we want to connect
network_manager = NetworkManager(
    connection_network=connection_network,
    config_network=config_network)

# run install() if is the first time and you want to install
# networks connection from brownie
# network_manager.install()

# Connect to network
network_manager.connect()


moc_main = MoC(network_manager).from_abi()

amount_want_to_mint = Decimal(0.001)

total_amount, commission_value = moc_main.amount_mint_bpro(amount_want_to_mint)
print("To mint {0} bitpro need {1} RBTC. Commision {2}".format(format(amount_want_to_mint, '.18f'),
                                                               format(total_amount, '.18f'),
                                                               format(commission_value, '.18f')))

print("Please wait to the transaction be mined!...")
tx_receipt = moc_main.mint_bpro(amount_want_to_mint)

# finally disconnect from network
network_manager.disconnect()

this print
