Creating secure, hierarchical deterministic (HD) wallets is a foundational skill for managing multiple cryptocurrencies safely. With the rise of digital assets like Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Bitcoin Cash (BCH), Bitcoin Gold (BTG), DASH, and Dogecoin (DOGE), developers and users alike need reliable tools to generate wallets without exposing private keys.
Enter pywallet — a lightweight Python library designed to simplify HD wallet creation across major blockchain networks. Built on trusted open-source foundations, pywallet streamlines the generation of mnemonic seeds, extended keys, and child addresses while maintaining strong security practices.
This guide walks you through installation, usage examples, and best practices for integrating pywallet into your cryptocurrency workflows — all while keeping your private data secure.
What Is an HD Wallet?
Hierarchical Deterministic (BIP32) wallets allow you to derive an infinite number of public addresses from a single master seed. This architecture ensures that:
- You can generate new receiving addresses without ever exposing your private key.
- All child wallets are cryptographically linked to a root seed.
- Recovery is simple: just restore using the original 12-word mnemonic.
This makes HD wallets ideal for applications requiring frequent address generation — such as exchanges, payment processors, or custodial services.

Supported Cryptocurrencies
Pywallet supports the following major blockchain networks:
- Bitcoin (BTC)
- Ethereum (ETH)
- Litecoin (LTC)
- Bitcoin Cash (BCH)
- Bitcoin Gold (BTG)
- DASH
- Dogecoin (DOGE)
Each network follows BIP44 standards where applicable, ensuring compatibility with most wallets and services.
Installation
Getting started with pywallet is straightforward using pip, the Python package manager.
sudo pip install pywalletEnsure you're running a compatible version of Python (2.7+ or 3.6+) and have pip installed. Once complete, you can begin generating wallets programmatically.
How to Create an HD Wallet
The first step in using pywallet is generating a secure mnemonic seed and creating a wallet for your desired cryptocurrency.
Example: Generate a Bitcoin HD Wallet
# create_btc_wallet.py
from pywallet import wallet
# Generate a 12-word BIP39 mnemonic
seed = wallet.generate_mnemonic()
# Create a Bitcoin wallet with one child address
w = wallet.create_wallet(network="BTC", seed=seed, children=1)
print(w)Sample Output
{
"coin": "BTC",
"seed": "guess tiny intact poet process segment pelican bright assume avocado view lazy",
"address": "1HwPm2tcdakwkTTWU286crWQqTnbEkD7av",
"xprivate_key": "xprv9s21ZrQH143K2Dizn667UCo9oYPdTPSMWq7D5t929aXf1kfnmW79CryavzBxqbWfrYzw8jbyTKvsiuFNwr1JL2qfrUy2Kbwq4WbBPfxYGbg",
"xpublic_key": "xpub661MyMwAqRbcEhoTt7d7qLjtMaE7rrACt42otGYdhv4dtYzwK3RPkfJ4nEjpFQDdT8JjT3VwQ3ZKjJaeuEdpWmyw16sY9SsoY68PoXaJvfU",
"wif": "L1EnVJviG6jR2oovFbfxZoMp1JknTACKLzsTKqDNUwATCWpY1Fp4",
"children": [
{
"address": "1E3btRwsoJx2jUcMnATyx7poHhV2tomL8g",
"path": "m/0",
"xpublic_key": "xpub69Fho5TtAbdoXyWzgUV1ZYst9K4bVfoGNLZxQ9u5js4Rb1jEyUjDtoATXbWvAcV8cERCMMnH8wYRVVUsRDSfaMjLqaY3TvD7Am9ALjq5PsG",
"wif": "KysRDiwJNkS9VPzy1UH76DrCDizsWKtEooSzikich792RVzcUaJP"
}
]
}🔐 Never expose yourseed,xprivate_key, orwifin production environments. Store them securely using encrypted vaults or hardware modules.
You can repeat this process for other networks by changing the network parameter.
Example: Ethereum Wallet Generation
# create_eth_wallet.py
from pywallet import wallet
seed = wallet.generate_mnemonic()
w = wallet.create_wallet(network="ETH", seed=seed, children=1)
print(w)Note: Ethereum does not use WIF (Wallet Import Format), so that field will be empty.
Generate Child Wallets Securely
One of the biggest advantages of HD wallets is the ability to create child addresses from an extended public key (xpub) — without ever revealing your private key.
This is perfect for backend servers that need to generate unique deposit addresses for users.
Example: Create Child Addresses
# create_child_wallet.py
from pywallet import wallet
WALLET_PUBKEY = 'YOUR WALLET XPUB'
# Generate a specific address for user ID 10
user_addr = wallet.create_address(network="BTC", xpub=WALLET_PUBKEY, child=10)
# Or generate a random address based on timestamp
rand_addr = wallet.create_address(network="BTC", xpub=WALLET_PUBKEY)
print("User Address\n", user_addr)
print("Random Address\n", rand_addr)Sample Output
User Address
{'address': '13myudz3WhpBezoZue6cwRUoHrzWs4vCrb', 'path': 'm/0/395371597'}
Random Address
{'address': '1KpS2wC5J8bDsGShXDHD7qdGvnic1h27Db', 'path': 'm/0/394997119'}This method ensures your server remains secure even if compromised — since no private keys are present.

Security Best Practices
While pywallet simplifies development, security ultimately depends on how you implement it.
Key Recommendations:
- Always generate the initial seed and private keys in a secure, offline environment.
- Never transmit or log sensitive data like mnemonics or xprv keys.
- Use environment variables or secure secret managers to store credentials.
- Validate input parameters before calling wallet functions.
- Regularly audit dependencies and keep pywallet updated.

Frequently Asked Questions (FAQ)
Q: Is pywallet safe to use in production?
A: Pywallet provides the tools, but safety depends on implementation. Always generate seeds and private keys offline and avoid logging sensitive data.
Q: Can I recover my wallet on other platforms?
A: Yes — as long as you have the 12-word mnemonic and know the derivation path (e.g., m/44'/0'/0'/0), you can restore your wallet in any BIP39/BIP44-compliant wallet.
Q: Why doesn’t Ethereum have a WIF key?
A: WIF is specific to Bitcoin-based chains. Ethereum uses different key formats — typically raw hex-encoded private keys.
Q: How many child addresses can I generate?
A: Theoretically unlimited. BIP32 allows for 2^31 child keys per level, which is more than sufficient for any practical use case.
Q: Does pywallet support testnets?
A: Native testnet support may vary. Check documentation or extend functionality by modifying network parameters manually.
