Web3Tools is an extender for the web3py library
Setup your PyPi credentials on ~/.pypirc
[pypi]
username = __token__
password = pypi-token
Accordingly with the setuptools on setup.py generate a new package for a given project and version. Two files (tar.gz and whl) will be added to dist/
python setup.py sdist bdist_wheel
Upload the packages within dist/ to PyPi
pip install twine
twine upload dist/*
from web3tools import Utils
Create an ethereum account
address, private_key = Utils.create()
keystore = Utils.encrypt(private_key, "myPassword")
Get address
private_key = Utils.decrypt("myKeystore", "myPassword")
address = Utils.get_address(private_key)
Sign a message & Recover signer's address
signature = Utils.sign_message("myPrivateKey", "myMessage")
address = Utils.recover_message(signature, "myMessage")
from web3tools import Ewt
ewt = Ewt()
Ewt Authentication, similar to jwt but using the ethereum encryption keys
ewt_token = ewt.generate("myPrivateKey")
is_valid = ewt.validate(ewt_token)
from web3tools import Reader
reader = Reader(Providers.INFURA_MAINNET.value.format("myInfuraKey"))
Crawl blockchain

transaction = reader.get_transaction("myTxid")
receipt = reader.get_receipt("myTxid")
gas_price = reader.get_gas_price()
Get Wallet Info
balance = reader.get_balance("myWallet")
nonce = reader.get_nonce("myWallet")
Read Contracts
contract = reader.get_contract_instance("abiFilePath", "contractAddress")
value = reader.call_view(contract, "viewName", "viewArguments")

from web3tools import Providers, Transactor
transactor = Transactor(Providers.INFURA_MAINNET.value.format("myInfuraKey"))
Send 1 Eth to receiverAddress
transactor.launch_transaction("myPrivateKey", "receiverAddress", transactor.to_wei(1))
Call a transfer function of a token contract to send 1 Token to receiverAddress
contract = transactor.get_contract_instance("abiFilePath", "contractAddress")
transactor.launch_function(contract, "myPrivateKey", "transfer",
"receiverAddress", transactor.to_wei(1))
