Simple BIP32 (HD) wallet creation for BTC, BTX, RVN, MXT, BTG, BCH, LTC, DASH, USDT, QTUM and DOGE
Project description
ZPyWallet
Simple BIP32 (HD) wallet creation for: BTC, BTX, RVN, MXT, BTG, BCH, ETH, LTC, DASH, DOGE
BIP32 (or HD for “hierarchical deterministic”) wallets allow you to create child wallets which can only generate public keys and don’t expose a private key to an insecure server.
This library simplify the process of creating new wallets for the BTC, BTX, RVN, MXT, BTG, BCH, ETH, LTC, DASH and DOGE cryptocurrencies.
This is a fork of PyWallet <https://github.com/ranaroussi/pywallet> with support for more coins, and some bugfixes.
Enjoy!
Installation
Install via PiP:
$ sudo pip install zpywallet
Example code:
Create HD Wallet
The following code creates a new Bitcoin HD wallet:
# create_btc_wallet.py
from zpywallet import wallet
# generate 12 word mnemonic seed
seed = wallet.generate_mnemonic()
# create bitcoin wallet
w = wallet.create_wallet(network="BTC", seed=seed, children=1)
print(w)
Output looks like this:
$ python create_btc_wallet.py
{
"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"
}]
}
Similarly, you can do the same for an Ethereum wallet:
# create_eth_wallet.py
from zpywallet import wallet
seed = wallet.generate_mnemonic()
w = wallet.create_wallet(network="ETH", seed=seed, children=1)
print(w)
Output looks like this (no WIF for Ethereum):
$ python create_eth_wallet.py
{
"coin": "ETH",
"seed": "traffic happy world clog clump cattle great toy game absurd alarm auction",
"address": "0x3b777f60eb04fcb13e6b27e468532e491409722e",
"xprivate_key": "xprv9yTuSjwb95QZznV6epMWpb4Kpc2S8ZRaQuAf5B697YXtQD2tDmmJ5KvwJWVjtbVrdJ1WBKNnuodrpTKGfHfiPSEgrAxUjL5RP1gQwwT3fFx",
"xpublic_key": "xpub6GhhMtkVjoPi5DKtqapKzMzrzdGjo1EPc7Ka6KdeoXYdCrTBH1Hu1wKysm8boWSy8VeTKVJi6gQJ2qJ4YG2ZhvFDcUUgMJrFCJWN1PGtBry",
"wif": "",
"children": [{
"address": "0x87eb82d43fa7316df0a989c0d951a9037ed02f9b",
"path": "m/0",
"xpublic_key": "xpub6LnpVXD73jNuAYXxzQCnEY6wXQspwkiAEkZWoX4BW9Tzx6KbUrMUYAU1Yvw4kebPHSPiEJPo8irHWHSwQR6WuVwUj85xURsugPWeJVH6sau",
"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_wallet.py
from zpywallet 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_child_wallet.py
User Address
{
"address": "13myudz3WhpBezoZue6cwRUoHrzWs4vCrb",
"path": "m/0/395371597"
}
Random Address
{
"address": "1KpS2wC5J8bDsGShXDHD7qdGvnic1h27Db",
"path": "m/0/394997119"
}
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!
