Hierarchical Deterministic Wallet

Python-based library for the implementation of a hierarchical deterministic wallet generator for multiple cryptocurrencies.

Available Cryptocurrencies

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

Quick Start

Simple Bitcoin cryptocurrency mainnet HDWallet generator:

#!/usr/bin/env python3

from hdwallet import HDWallet
from hdwallet.utils import generate_entropy
from 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 hex string
ENTROPY: str = generate_entropy(strength=STRENGTH)
# Secret passphrase for mnemonic
PASSPHRASE: Optional[str] = None  # "meherett"

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

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

# Initialize Ethereum mainnet BIP44HDWallet
bip44_hdwallet: BIP44HDWallet = BIP44HDWallet(cryptocurrency=EthereumMainnet)
# Get Ethereum BIP44HDWallet from mnemonic
bip44_hdwallet.from_mnemonic(
    mnemonic=MNEMONIC, passphrase=PASSPHRASE
