This Python3 module implements support for Elements transactions.
It builds on top, and is intended to be used along with python-bitcointx library.
-
python-bitcointx (version >= 1.0.0)
-
Configure parameters for
secp256k1-zkp:
./configure --enable-experimental \
--enable-module-generator \
--enable-module-rangeproof \
--enable-module-surjectionproof \
--enable-module-ecdh \
--enable-module-recovery
With contextual switch to Elements parameters:
import os
import elementstx
from bitcointx import ChainParams, get_current_chain_params
from bitcointx.wallet import CCoinKey, CCoinExtKey, CCoinAddress, P2PKHCoinAddress
with ChainParams('elements'):
k = CCoinExtKey.from_seed(os.urandom(32))
a = P2PKHCoinAddress.from_pubkey(k.derive_path("m/0'/0'/1").pub)
print('example {} address: {}'.format(get_current_chain_params().name, a))
assert CCoinAddress(str(a)) == aWith global switch to Elements parameters:
from elementstx import ElementsParams
from bitcointx import select_chain_params
select_chain_params('elements')
# or, using the chain params class directly
select_chain_params(ElementsParams)
# To switch to Liquid Network parameters:
select_chain_params('elements/liquidv1')Without the switch of chain parameters:
from elementstx.core import CElementsTransaction
transaction_data = read_tx_data()
tx = CElementsTransaction.deserialze(transaction_data)
print("Number of txout witnesses:", len(tx.wit.vtxoutwit))See examples/ directory.
