I tried to generate wallets by using pywallet and bip32utils (Python). But I noted that the addresses/keys of the 2 wallets, namely wallet_pywallet and wallet_bip39 don't match with each other.

I noted that the addresses/keys of wallet_bip39 match with Exodus, but wallet_pywallet doesn't. We have been using pywallet for such a long time so I believe wallet_pywallet should be correct as well. Why is there such a discrepancy?

Below is the code, while the code for wallet_bip39 is obtained from this post.

from pywallet import wallet
import binascii
import mnemonic
import bip32utils

def bip39(mnemonic_words):
    mobj = mnemonic.Mnemonic("english")
    seed = mobj.to_seed(mnemonic_words)

    bip32_root_key_obj = bip32utils.BIP32Key.fromEntropy(seed)
    bip32_child_key_obj = bip32_root_key_obj.ChildKey(
        44 + bip32utils.BIP32_HARDEN
        0 + bip32utils.BIP32_HARDEN
        0 + bip32utils.BIP32_HARDEN

    return {
        'mnemonic_words': mnemonic_words,
        'addr': bip32_child_key_obj.Address(),
        'publickey': binascii.hexlify(bip32_child_key_obj.PublicKey()).decode(),
        'privatekey': bip32_child_key_obj.WalletImportFormat(),
        'coin': 'BTC'

mnemonic_words = wallet.generate_mnemonic()
wallet_pywallet = wallet.create_wallet(network="BTC", seed=mnemonic_words, children=0)
wallet_bip39 = bip39(mnemonic_words)

Derivation paths.

wallet_bip39 is using m/44'/0'/0' while (if I looked at the right pywallet code) pywallet is using m/0'

  • Thanks for your reply. I tried to change the bip39()'s code to bip32_child_key_obj = bip32_root_key_obj.ChildKey(0 + bip32utils.BIP32_HARDEN).ChildKey(0).ChildKey(0), but the keys/addresses of the two wallets still don't match with each other.
