bsvlib
A Bitcoin SV (BSV) Python Library that is extremely simple to use but more.
- MAINNET and TESTNET supported
- P2PKH and P2PK supported
- All the SIGHASH flags supported
- Additional script types can be customized
- Ability to adapt to different service providers
Installation
$ pip install bsvlib
Examples
- Send BSV in one line.
from bsvlib import Wallet
# Donate to aaron67!
print(Wallet(['YOUR_WIF_GOES_HERE']).send_transaction(outputs=[('1HYeFCE2KG4CW4Jwz5NmDqAZK9Q626ChmN', 724996)]))
- Good to send unspent locked by different keys in one transaction, and OP_RETURN output is supported as well
from bsvlib import Wallet
from bsvlib.constants import Chain
w = Wallet(chain=Chain.TEST)
w.add_key('cVwfreZB3i8iv9JpdSStd9PWhZZGGJCFLS4rEKWfbkahibwhticA')
w.add_key('93UnxexmsTYCmDJdctz4zacuwxQd5prDmH6rfpEyKkQViAVA3me')
print(w.get_balance(refresh=True))
outputs = [('mqBuyzdHfD87VfgxaYeM9pex3sJn4ihYHY', 724), ('mr1FHq6GwWzmD1y8Jxq6rNDGsiiQ9caF7r', 996)]
pushdatas = ['hello', b'world']
print(w.send_transaction(outputs=outputs, pushdatas=pushdatas, combine=True))
- Operate P2PK
from bsvlib import Wallet, TxOutput, Transaction
from bsvlib.keys import Key
from bsvlib.script import P2pkScriptType
from bsvlib.service import SensibleQuery
private_key = Key('L5agPjZKceSTkhqZF2dmFptT5LFrbr6ZGPvP7u4A6dvhTrr71WZ9')
w = Wallet(provider=SensibleQuery())
w.add_key(private_key)
w.add_key('5KiANv9EHEU4o9oLzZ6A7z4xJJ3uvfK2RLEubBtTz1fSwAbpJ2U')
t = Transaction()
t.add_inputs(w.get_unspents(refresh=True))
t.add_output(TxOutput(P2pkScriptType.locking(private_key.public_key().serialize()), 996, P2pkScriptType()))
t.add_change(private_key.address())
print(t.sign().broadcast())
- Sign with different SIGHASH flags, more examples
from bsvlib import Wallet, Transaction, TxInput, TxOutput
from bsvlib.constants import SIGHASH
from bsvlib.keys import Key
private_key = Key('L5agPjZKceSTkhqZF2dmFptT5LFrbr6ZGPvP7u4A6dvhTrr71WZ9')
unspents = Wallet([private_key]).get_unspents(refresh=True)
t = Transaction()
t.add_input(TxInput(unspents[0], sighash=SIGHASH.SINGLE_FORKID))
t.add_output(TxOutput(private_key.address(), 135))
t.sign()
# it's good to append any outputs AFTER the first output, no need to sign, can broadcast directly
print(t.add_change().broadcast())
