Python client library used in SKALE network components.

• Python 3.7+ support
• Compatibility with web3.py v6

pip install skale.py

• Ledger Wallet (works with Ledger Nano S and other models)
• RPC Wallet (works with SKALE Transactions Manager)
• SGX Wallet (works with SKALE SGX Wallet)
• Web3 Wallet (works with web3.py embeded functions)

With embeded Web3Wallet

from skale import SkaleManager
from skale.wallets import Web3Wallet
from skale.utils.web3_utils import init_web3

web3 = init_web3(ENDPOINT)
wallet = Web3Wallet(private_key, web3)
skale = Skale(ENDPOINT, ABI_FILEPATH, wallet)

With external transactions manager:

from skale import SkaleManager
from skale.wallets import RPCWallet

web3 = init_web3(ENDPOINT)
wallet = RPCWallet(TM_URL)
skale = Skale(ENDPOINT, ABI_FILEPATH, wallet)

Interactions with SKALE contracts

active_nodes = skale.nodes.get_active_node_ips()
schains = skale.schains.get_schains_for_owner('0x...')

Due to the web3.py v5 limitations you have to create separate instances of the skale.py for the each thread.
Take a look on the tests/multithreading_test.py for the reference.

You can find usage examples here.

. venv/bin/activate 
pip install -e .[dev]

bash build_and_publish.sh major/minor/patch

 export $(cat .env | xargs) && bash build_and_publish.sh major/minor/patch
