Installation

Install via PiP:

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, 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",

     "path": "m/0",
     "xpublic_key": "xpub69Fho5TtAbdoXyWzgUV1ZYst9K4bVfoGNLZxQ9u5js4Rb1jEyUjDtoATXbWvAcV8cERCMMnH8wYRVVUsRDSfaMjLqaY3TvD7Am9ALjq5PsG",

 }]
}

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, 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",

    "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 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_child_wallet.py

User Address
{
  "address": "13myudz3WhpBezoZue6cwRUoHrzWs4vCrb",
  "path": "m/0/395371597"
}
Random Address
{
  "address": "1KpS2wC5J8bDsGShXDHD7qdGvnic1h27Db",
  "path": "m/0/394997119"
}
