Litecoin module for use with python-bitcointx

Project description

This Python3 library implements support for Litecoin transactions.

It builds on top, and is intended to be used along with python-bitcointx library.



With contextual switch to Litecoin parameters:

import os
import litecointx
from bitcointx import ChainParams, get_current_chain_params
from bitcointx.wallet import (
    CCoinKey, CCoinExtKey, P2WPKHCoinAddress, CCoinAddress

with ChainParams('litecoin'):
    k = CCoinExtKey.from_seed(os.urandom(32))
    a = P2WPKHCoinAddress.from_pubkey(k.derive_path("m/0h/0h/1").pub)
    print('example {} address: {}'.format(get_current_chain_params().NAME, a))
    assert CCoinAddress(str(a)) == a

With global switch to Litecoin parameters:

from litecointx import LitecoinMainnetParams
from bitcointx import select_chain_params

# or, using the chain params class directly

Without the switch of chain parameters:

from litecointx.wallet import P2SHLitecoinLegacyAddress, P2SHLitecoinAddress

legacy_adr = P2SHLitecoinLegacyAddress('3F1c6UWAs9RLN2Mbt5bAJue12VhVCorXzs')
canonical_adr = P2SHLitecoinAddress.from_scriptPubKey(legacy_adr.to_scriptPubKey())
assert str(canonical_adr) == 'MMDkQMv8pGGmAXdVyxaW8YtQMCHw7eouma'

With special parameter that makes CCoinAddress to decode legacy p2sh addresses:

from bitcointx import select_chain_params
from bitcointx.wallet import CCoinAddress
from litecointx.wallet import P2SHLitecoinLegacyAddress

select_chain_params('litecoin', allow_legacy_p2sh=True)
legacy_adr = CCoinAddress('3F1c6UWAs9RLN2Mbt5bAJue12VhVCorXzs')
assert isinstance(legacy_adr, P2SHLitecoinLegacyAddress)

this also works with ChainParams context manager.
