Objective

The BSV Blockchain Libraries Project aims to structure and maintain a middleware layer of the BSV Blockchain technology stack. By facilitating the development and maintenance of core libraries, it serves as an essential toolkit for developers looking to build on the BSV Blockchain.

Getting Started

Installation

pip install bsv-sdk

Basic Usage

import asyncio
from bsv import (
    PrivateKey, P2PKH, Transaction, TransactionInput, TransactionOutput
)


# Replace with your private key (WIF format)
PRIVATE_KEY = 'KyEox4cjFbwR---------VdgvRNQpDv11nBW2Ufak'

# Replace with your source tx which contains UTXO that you want to spend (raw hex format)
SOURCE_TX_HEX = '01000000018128b0286d9c6c7b610239bfd8f6dcaed43726ca57c33aa43341b2f360430f23020000006b483045022100b6a60f7221bf898f48e4a49244e43c99109c7d60e1cd6b1f87da30dce6f8067f02203cac1fb58df3d4bf26ea2aa54e508842cb88cc3b3cec9b644fb34656ff3360b5412102cdc6711a310920d8fefbe8ee73b591142eaa7f8668e6be44b837359bfa3f2cb2ffffffff0201000000000000001976a914dd2898df82e086d729854fc0d35a449f30f3cdcc88acce070000000000001976a914dd2898df82e086d729854fc0d35a449f30f3cdcc88ac00000000'

async def create_and_broadcast_transaction():
    priv_key = PrivateKey(PRIVATE_KEY)
    source_tx = Transaction.from_hex(SOURCE_TX_HEX)

    tx_input = TransactionInput(
        source_transaction=source_tx,
        source_txid=source_tx.txid(),
        source_output_index=1,
        unlocking_script_template=P2PKH().unlock(priv_key),
    )

    tx_output = TransactionOutput(
        locking_script=P2PKH().lock(priv_key.address()),
        change=True
    )

    tx = Transaction([tx_input], [tx_output], version=1)

    tx.fee()
    tx.sign()

    await tx.broadcast()

    print(f"Transaction ID: {tx.txid()}")
    print(f"Raw hex: {tx.hex()}")

if __name__ == "__main__":
    asyncio.run(create_and_broadcast_transaction())
