Installing

Installing from PyPI repository (https://pypi.org/project/icplazapy):

pip install icplazapy

Usage

Generating a wallet

from icplazapy import generate_wallet

wallet = generate_wallet()

The value assigned to wallet will be a dictionary just like:

{
    'seed': 'loan weapon tone clever party picture spot novel almost change rug primary speak entry usage maximum farm beyond magnet crazy later day addict orchard', 
    'derivation_path': "m/44'/118'/0'/0/0", 
    'private_key': b'\x06\xe5*di\x88q0\xe4\x08Y\x9aL\xcb\xd7\xc0\xac\xc6\x9d\x9a\x18\xc5$\x00\xacM5\xae\x1b\x07\xe7N', 'public_key': b'\x02Jj\xe8>y\xe0\xcb\xe2\x11oIX@29p\xd3\x1c\x83\xcd\xa4i\xb0\x9e\xd7\x9f!\xf5\xbe\xb7\xe1i', 
    'address': 'icplaza1ayuhuzmlkw3dr7ftajxcl9kzg4vvzr0ltwpwjl'
}

Converter functions

Mnemonic seed to private key

from icplazapy import BIP32DerivationError, seed_to_privkey

seed = (
    "teach there dream chase fatigue abandon lava super senior artefact close upgrade"
)
try:
    privkey = seed_to_privkey(seed, path="m/44'/118'/0'/0/0")
except BIP32DerivationError:
    print("No valid private key in this derivation path!")

Private key to public key

from icplazapy import privkey_to_pubkey

privkey = bytes.fromhex(
    "6dcd05d7ac71e09d3cf7da666709ebd59362486ff9e99db0e8bc663570515afa"
)
pubkey = privkey_to_pubkey(privkey)

Public key to address

from icplazapy import pubkey_to_address

pubkey = bytes.fromhex(
    "03e8005aad74da5a053602f86e3151d4f3214937863a11299c960c28d3609c4775"
)
addr = pubkey_to_address(pubkey)

Private key to address

from icplazapy import privkey_to_address

privkey = bytes.fromhex(
    "6dcd05d7ac71e09d3cf7da666709ebd59362486ff9e99db0e8bc663570515afa"
)
addr = privkey_to_address(privkey)

Public key to hex address

from icplazapy import pubkey_to_hex_address

pubkey = bytes.fromhex(
    "03e8005aad74da5a053602f86e3151d4f3214937863a11299c960c28d3609c4775"
)
addr = pubkey_to_address(pubkey)

Private key to hex address

from icplazapy import privkey_to_hex_address

privkey = bytes.fromhex(
    "6dcd05d7ac71e09d3cf7da666709ebd59362486ff9e99db0e8bc663570515afa"
)
addr = privkey_to_address(privkey)

address from hex address

from icplazapy import from_hex_address
hex_addr = "0x4790155804CB6fd0D3697CBb367E75397408a587"
addr = from_hex_address(hex_addr)

address to hex address

from icplazapy import to_hex_address
addr = "icplaza1g7gp2kqyedhap5mf0janvln4896q3fv87z2dm6"
hex_addr = to_hex_address(addr)

Signing transactions

from icplazapy import Transaction

tx = Transaction(
    privkey=bytes.fromhex(
        "26d167d549a4b2b66f766b0d3f2bdbe1cd92708818c338ff453abde316a2bd59"
    ),
    account_num=11335,
    sequence=0,
    fee=1000,
    gas=70000,
    memo="",
    chain_id="icplaza_9000-4",
    sync_mode="sync",
)
tx.add_transfer(
    recipient="icplaza1g7gp2kqyedhap5mf0janvln4896q3fv87z2dm6", amount=387000
)

pushable_tx = tx.get_pushable()


# Optionally submit the transaction using your preferred method.
# This example uses the httpx library.
import httpx

# icplaza rest api
api_base_url = ""
httpx.post(api_base_url + "/txs", data=pushable_tx)

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 the Cosmos REST API.
