🐳 Library including all the common functionalities used in Python projects

ocean-keeper

Wraps keeper contracts and web3 functions.

How to

The main class is Keeper and all contracts are accessible directly from the keeper instance. Each deployed contract has a python wrapper class exposing the main functions and validating inputs.

import os
from ocean_keeper import Keeper
from ocean_keeper.contract_handler import ContractHandler
from ocean_keeper.web3_provider import Web3Provider
from ocean_keeper.utils import get_account

# Init the web3 instance
Web3Provider.init_web3('http://localhost:8545')  # Assume running with local parity node
# set the contract handler path to abi files
ContractHandler.set_artifacts_path(os.path.expanduser('~/.ocean/keeper-contracts/artifacts'))
# get keeper instance
keeper = Keeper.get_instance(artifacts_path=ContractHandler.artifacts_path)
# Do stuff with keeper and it's contracts
account = get_account(0)
keeper.did_registry.register('0x10101010101010101010', '', 'http://localhost:5000/api/v1/assets', account)

Account can be specified using the following environment variables:

• PARITY_ADDRESS: the ethereum address
• PARITY_PASSWORD: the password to decrypt key in the PARITY_ENCRYPTED_KEY
• PARITY_KEY: the private key of this account (matches the PARITY_ADDRESS)
• PARITY_ENCRYPTED_KEY: the encrypted key in a json str
• PARITY_KEYFILE: path to the json file that has the encrypted key specified in json document

Note: The keys are loaded in this order: PARITY_KEY, PARITY_ENCRYPTED_KEY, PARITY_KEYFILE. If PARITY_KEY is specified the password and other environment variables are ignored.
