Simple HD wallet creation for BTC, BTG, BCH, LTC, DASH and DOGE

PyWallet

Simple HD wallet creation for: BTC, BTG, BCH, LTC, DASH, DOGE

Most of the code here is forked from:

• Steven Buss’s Bitmerchant (original)

• BlockIo’s multimerchant-python (fork of Bitmerchant)

• Michail Brynard’s Ethereum BIP44 Python

I simply added support for a few more cryptocurrencies (BCH, BTG, DASH), as well as created methods to simplify the creation of HD wallets and child wallets.

Enjoy!

Installation

Install via PiP:

$ sudo pip install pywallet

Example code:

Create HD Wallet

The following code creates a new Bitcoin HD wallet:

# create_btc_wallet.py

from pywallet import wallet

# generate 12 word mnemonic seed
seed = wallet.generate_mnemonic()

# create bitcoin wallet
w = wallet.create_wallet(network="BTC", seed=seed)

print(w)

Output looks like this:

$ python create_btc_wallet.py

{
 'coin': 'BTC',
 'seed': 'tool innocent picnic fluid silent ask minute scheme rural crumble decrease rescue',
 'address': '1CPG2MU2fbXKfqi3pdBF3WaiodE28uB6ns',
 'xprivate_key': 'xprv9s21ZrQH143K4WwrikXgmThRVAXko6oSNKcG5AUyRhYQCmmUX18eZUpcB98T3DP73jqgq7JrLEaXLkUs5cQ4HnCmtVuNVTbfRx9GRB1duuX',
 'xpublic_key': 'xpub661MyMwAqRbcH12Kpn4h8beA3CNFCZXHjYXrsYtaz35P5a6d4YSu7H962Rt1nzo6q5rhHmTCTcxSaNFG2UtAQdy4pAuLqaz5gAmSx76t5Ab',
 'wif': 'KzkcdtrAPY3CctyzLJARA3rC8gUHEdrk1V8hN3GGE2UHJvaFEhA2'
}

Similarly, you can do the same for an Ethereum wallet:

# create_eth_wallet.py

from pywallet import wallet

seed = wallet.generate_mnemonic()
w = wallet.create_wallet(network="ETH", seed=seed)

print(w)

Output looks like this (no WIF for Ethereum):

$ python create_eth_wallet.py

{
 'coin': 'ETH',
 'seed': 'cactus father lecture ahead strategy parrot genre kind crew lock merit unfair',
 'address': '0x6497148e392fc5703db95be03cc5cbb81009d3b2',
 'xprivate_key': 'xprv9zJtR6McPYXYpQGeUgAy219NSPBiHXmP8kzwsMJVRjGd86r4cDgZotQJaXH1TAZ2MSFKoPE6pYUe3cTEgRAdwXKt9enhoc7PnF7opkwdBqP',
 'xpublic_key': 'xpub6DJEpbtWDv5r2tM7ahhyP966zR2CgzVEVyvYfji6z4obzuBD9kzpMginRnczVeuxXjvQFEGDEgdKzTB4r8Q2aUUa5GAZxDfogChbrZxj3Cj',
 'wif': ''
}

* Valid options for network are: BTC, BTG, BCH, LTC, DASH, DOGE

Create Child Wallet

You can create child-wallets (BIP32 wallets) from the HD wallet’s Extended Public Key to generate new public addresses without revealing your private key.

Example:

# create_child_btc_wallet.py

from pywallet import wallet

WALLET_PUBKEY = 'YOUR WALLET XPUB'

# generate address for specific 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)

Output looks like this:

$ python create_eth_wallet.py

User Address
 1FxgaPRGHcY7JGg5jqdwx4kYgiP3xB1aX7
Random Address
 1KpS2wC5J8bDsGShXDHD7qdGvnic1h27Db

IMPORTANT

I highly recommend that you familiarize yourself with the Blockchain technology and be aware of security issues. Reading Mastering Bitcoin and going over Steven Buss’s security notes on the Bitmerchant repository is a good start.

Enjoy!
