Installing

Require Python >= 3.7, installing from PyPI repository (https://pypi.org/project/chainlibpy):

pip install chainlibpy

Usage

Generating a wallet

from chainlibpy import Wallet

# create a wallet
wallet = Wallet.new()
# or you can recover from an mnomic
# mnemonic = "dune car envelope chuckle elbow slight proud fury remove candy uphold puzzle call select sibling sport gadget please want vault glance verb damage gown"
# wallet = Wallet(mnemonic)

print(wallet.private_key)
print(wallet.public_key)
print(wallet.address)

Signing transactions

from chainlibpy import Transaction, Wallet
from chainlibpy.amino import StdFee, Coin
from chainlibpy.amino.message import MsgSend

wallet = Wallet.new()
fee = StdFee("300000", [Coin("100000")])
tx = Transaction(
    wallet=wallet,
    account_num=11335,
    sequence=0,
    fee=fee,
    memo="",
    chain_id="test",
    sync_mode="sync",
)
from_add = wallet.address
msg = MsgSend(
    from_address=wallet.address,
    to_address="cro103l758ps7403sd9c0y8j6hrfw4xyl70j4mmwkf",
    amount="387000",
)
tx.add_msg(msg)
pushable_tx = tx.get_pushable()

One or more token transfers can be added to a transaction by calling the add_transfer method.

When the transaction is fully prepared, calling get_pushable will return a signed transaction in the form of a JSON string. This can be used as request body when calling the POST /txs endpoint of rpc.

thanks

thanks cosmospy for the following:

• referenced the packages to sign transaction and create hd wallet
• python lint config file
• use same sign method
