From entropy, BIP84

[pbies]

Hi!

Need help with getting BIP84 HD wallet from entropy.

For now I don't see from_entropy function in new, 3.2.0 version with BIP84.

Do I need to go back with HDWallet version, or it can be done in 3.2.0?

Thank you

Hello @pbies,

In Version 3, the from_entropy and from_mnemonic root functions are not available in all HD classes. Instead, the root function starts with from_seed. To use entropy or a mnemonic, you need to convert them into a seed first.

For further details: https://github.com/talonlab/python-hdwallet/blob/master/clients/bip84.py#L50

Alternatively, if you prefer to use from_entropy and from_mnemonic directly, consider using the HDWallet class instead of the specific HD classes.

See this example: https://github.com/talonlab/python-hdwallet/blob/master/examples/BIPs/from_entropy.py

Thanks!

Which BIPs/BIPxxHDs are the default ones for Bitcoin? I see: 84, 39, 44, 32.
I need from_entropy, from_seed and from_private_key for standard Bitcoins. The ones used in Bitcoin Core.
I will be converting to all 7 address types.
In which places use which BIPs?

I have code like:

from hdwallet import HDWallet
from hdwallet.cryptocurrencies import Bitcoin as BTC
from hdwallet.entropies import BIP39Entropy
from hdwallet.hds import BIP84HD
from hdwallet.mnemonics import BIP39Mnemonic
from hdwallet.seeds import BIP39Seed

hdwallet=HDWallet(cryptocurrency=BTC, hd=BIP84HD).from_mnemonic(mnemonic=BIP39Mnemonic(mnemonic=k))
hdwallet=HDWallet(cryptocurrency=BTC, hd=BIP84HD).from_private_key(private_key=k)
hdwallet=HDWallet(cryptocurrency=BTC, hd=BIP84HD).from_seed(seed=BIP39Seed(k))
hdwallet=HDWallet(cryptocurrency=BTC, hd=BIP84HD).from_wif(wif=k)
hdwallet=HDWallet(cryptocurrency=BTC, hd=BIP84HD).from_xprivate_key(xprivate_key=k)
hdwallet=HDWallet(cryptocurrency=BTC, hd=BIP84HD).from_entropy(entropy=BIP39Entropy(k))

and then printing addresses from hdwallet.

Bitcoin Core typically defaults to the following address types:

• Legacy Addresses (P2PKH): Based on BIP44HD, though these are now seldom used due to inefficiency.
• Nested SegWit Addresses (P2WPKH-In-P2SH): Aligned with BIP49HD, offering compatibility with older systems.
• Native SegWit (P2WPKH): Defined by BIP84HD, this is the preferred format for modern wallets.
• Taproot Addresses (P2TR): Specified by BIP86HD, used for advanced functionalities like complex smart contracts.

If you aim to convert to all 7 address types, you can use BIP32HD. However, this is not the default approach used by Bitcoin Core.

Thank you very much!
