Python-HDWallet

Python-based library for the implementation of a Hierarchical Deterministic (HD) wallet generator for Cryptocurrencies.

Available Cryptocurrencies

This library simplify the process of creating new HDWallet's for:

Cryptocurrencies	Symbols	Mainnet	Testnet	Coin Type	Default Paths
Bitcoin	BTC, BTCTEST	Yes	Yes	0	m/44'/0'/0'/0/0
Ethereum	ETH, ETHTEST	Yes	Yes	60	m/44'/60'/0'/0/0
Dogecoin	DOGE, DOGETEST	Yes	Yes	3	m/44'/3'/0'/0/0
Litecoin	LTC, LTCTEST	Yes	Yes	2	m/44'/2'/0'/0/0
Omni	OMNI, OMNITEST	Yes	Yes	200	m/44'/200'/0'/0/0
Dash	DASH, DASHTEST	Yes	Yes	5	m/44'/5'/0'/0/0
Qtum	QTUM, QTUMTEST	Yes	Yes	88	m/44'/88'/0'/0/0

BIP39 Mnemonic code for generating deterministic keys:

Entropy	Checksum	Entropy + Checksum	Mnemonic Length
128	4	132	12
160	5	165	15
192	6	198	18
224	7	231	21
256	8	264	24

BIP44 Path	m/44'/coin_type'/{account}'/{change}/{address}

NOTICE: All Cryptocurrencies testnet network default paths are set to m/44'/1'/0'/0/0 except Ethereum and also Ethereum cryptocurrency ETHTEST testnet is an alias of ETH mainnet network.

Quick Start

Simple Bitcoin cryptocurrency mainnet HDWallet generator:

#!/usr/bin/env python3

from python_hdwallet import PythonHDWallet as HDWallet
from python_hdwallet.utils import generate_entropy
from python_hdwallet.symbols import BTC
from typing import Optional

import json

# Choose strength 128, 160, 192, 224 or 256
STRENGTH: int = 160  # Default is 128
# Choose language english, french, italian, spanish, chinese_simplified, chinese_traditional, japanese or korean
LANGUAGE: str = "korean"  # Default is english
# Generate new entropy
ENTROPY: str = generate_entropy(strength=STRENGTH)
# Secret passphrase/password for mnemonic
PASSPHRASE: Optional[str] = None  # str("meherett")

# Initialize Bitcoin mainnet HDWallet
hdwallet: HDWallet = HDWallet(symbol=BTC)
# Get Bitcoin HDWallet from entropy
hdwallet.from_entropy(
    entropy=ENTROPY, passphrase=PASSPHRASE, language=LANGUAGE
)

# Derivation from path
# hdwallet.from_path("m/44'/0'/0'/0/0")
# Or derivation from index
hdwallet.from_index(44, harden=True)
hdwallet.from_index(0, harden=True)
hdwallet.from_index(0, harden=True)
hdwallet.from_index(0)
hdwallet.from_index(0)

# Print all Bitcoin HDWallet information's
print(json.dumps(hdwallet.dumps(), indent=4, ensure_ascii=False))

Ethereum cryptocurrency testnet Ganache-CLI/TestRPC wallet look's like:

#!/usr/bin/env python3

from python_hdwallet import PythonHDWallet
from python_hdwallet.cryptocurrencies import EthereumMainnet  # Alias EthereumTestnet
from python_hdwallet.utils import generate_mnemonic
from typing import Optional

# Choose strength 128, 160, 192, 224 or 256
STRENGTH: int = 128  # Default is 128
# Choose language english, french, italian, spanish, chinese_simplified, chinese_traditional, japanese or korean
LANGUAGE: str = "english"  # Default is english
# Generate new mnemonic words
MNEMONIC: str = generate_mnemonic(language=LANGUAGE, strength=STRENGTH)
# Secret passphrase/password for mnemonic
PASSPHRASE: Optional[str] = None  # str("meherett")

# Initialize Ethereum mainnet HDWallet
python_hdwallet: PythonHDWallet = PythonHDWallet(cryptocurrency=EthereumMainnet)
# Get Ethereum HDWallet from mnemonic
python_hdwallet.from_mnemonic(
    mnemonic=MNEMONIC, passphrase=PASSPHRASE, language=LANGUAGE
)

print("Mnemonic:", python_hdwallet.mnemonic())
print("Base HD Path:  m/44'/60'/0'/0/{address_index}", "\n")

# Get Ethereum HDWallet information's from address indexes
for address_index in range(10):
    # Derivation from Ethereum BIP44 path
    python_hdwallet.from_path(
        path=EthereumMainnet.BIP44_PATH.format(
            account=0, change=0, address=address_index
        )
    )
    # Print address_index, path, address and private_key
    print(f"({address_index}) {python_hdwallet.path()} {python_hdwallet.address()} 0x{python_hdwallet.private_key()}")
    # Clean derivation indexes/path
    python_hdwallet.clean_derivation()

Output
