Assumptions:
- You have a Bitcoin address with a positive balance.
- You have the private key for that address.
- You want to send a certain amount of BTC to another address.
Step 1: Prepare the transaction inputs
Let’s say we want to send 0.01 BTC from address 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
to address 1B1tP1eP5QGefi2DMPTfTL5SLmv7DivfNb
. We need to get the UTXOs (Unspent Transaction Outputs) for the sender address.
Using a tool like bitcoin-cli
or a block explorer, we get the following UTXO:
{
"txid": "54625789abcdef0123456789abcdef0123456789abcdef0",
"vout": 0,
"scriptPubKey": "76a9141a1zp1ep5qgefi2dmptftl5slmv7divfna88ac",
"amount": 0.1,
"confirmations": 100
}
Step 2: Create the transaction
Using the signing.py
file, let’s create a new transaction:
import hashlib
from sign import sign_tx
# Set the transaction inputs
txid = bytes.fromhex("54625789abcdef0123456789abcdef0123456789abcdef0")
vout = 0
scriptPubKey = bytes.fromhex("76a9141a1zp1ep5qgefi2dmptftl5slmv7divfna88ac")
amount = 0.1
# Set the transaction outputs
output_amount = 0.01
output_scriptPubKey = bytes.fromhex("76a9141b1tp1ep5qgefi2dmptftl5slmv7divfnb88ac")
# Create the transaction
tx = {
"version": 1,
"inputs": [
{"txid": txid, "vout": vout, "scriptPubKey": scriptPubKey, "amount": amount}
],
"outputs": [
{"amount": output_amount, "scriptPubKey": output_scriptPubKey}
],
"locktime": 0
}
Step 3: Sign the transaction
Using the sign.py
file, let’s sign the transaction with the private key:
import ecdsa
from sign import sign_tx
# Load the private key
private_key = ecdsa.SigningKey.from_secret_exponent(1234567890abcdef, curve=ecdsa.SECP256k1)
# Sign the transaction
signature = sign_tx(tx, private_key)
Step 4: Create the RawTX transaction
Using the main.py
file, let’s create the RawTX transaction:
from main import serialize_tx
# Serialize the transaction
raw_tx = serialize_tx(tx, signature)
print(raw_tx.hex())
Output:
The output will be a hexadecimal string representing the RawTX transaction.
Here’s an example output:
“`
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

amount_in_satoshi = 100000 # Количество сатоши для отправки (1 BTC = 100,000,000 сатоши)
fee_in_satoshi = 10000 # Размер комиссии в сатоши
# Получение информации о балансе и непотраченных выходах
unspent_outputs = get_unspent_outputs(private_key)
balance_in_satoshi = sum(output['value'] for output in unspent_outputs)
# Проверка достаточности баланса
if balance_in_satoshi < amount_in_satoshi + fee_in_satoshi:
print("Недостаточно средств на балансе.")
exit()
# Создание транзакции
tx = create_transaction(unspent_outputs, destination_address, amount_in_satoshi, fee_in_satoshi)
# Подписывание транзакции
signed_tx = sign_transaction(tx, private_key)
# Broadcast транзакции
broadcast_transaction(signed_tx)
print("Транзакция успешно отправлена!")
Убедитесь, что вы заменили "ваш_частный_ключ"
на свой частный ключ в формате шестнадцатеричного числа и "адрес_получателя"
на адрес Bitcoin получателя.
Этот скрипт использует предоставленный вами исходный код для создания, подписания и отправки транзакции Bitcoin с положительным балансом монет BTC. Он получает информацию о балансе и непотраченных выходах, создает транзакцию, подписывает ее вашим частным ключом и затем отправляет ее в сеть Bitcoin.
Помните, что работа с криптовалютами и частными ключами требует особой осторожности и безопасности. Убедитесь, что вы понимаете риски и принимаете необходимые меры предосторожности перед использованием такого кода.
To create a Bitcoin RawTX transaction with a positive balance of BTC coins using the provided source code links, you will need to follow these general steps:
- Install the required dependencies: python3, pip, and the python libraries mentioned in the source code.
- Download the source code files from the provided links: main.py, secp256k1.py, sighash.py, sign.py, and signing.py.
- Extract the contents of the downloaded files and place them in a new directory.
- Open the main.py file in a text editor and modify the following variables to match your Bitcoin wallet and transaction details:
private_key
: the private key associated with the Bitcoin address you want to send BTC from.recipient_address
: the Bitcoin address you want to send BTC to.amount_btc
: the amount of BTC you want to send.
- Save the changes to main.py and run the script using the command
python3 main.py
.
Here is an example of what the modified main.py file might look like:
import secp256k1, sighash, sign, signing
private_key = 'your_private_key_here'
recipient_address = 'recipient_bitcoin_address_here'
amount_btc = 0.01
utxos = get_utxos(recipient_address)
total_satoshis = sum([utxo['satoshis'] for utxo in utxos])
inputs = []
for utxo in utxos:
txid = utxo['txid']
vout = utxo['vout']
script_pubkey = utxo['script_pubkey']
amount = utxo['satoshis']
inputs.append({
'txid': txid,
'vout': vout,
'script_pubkey': script_pubkey,
'amount': amount,
'sequence': 0xffffffff
})
outputs = [
{
'recipient_address': recipient_address,
'amount': amount_btc * 1e8
}
]
change_address = recipient_address
change_amount = total_satoshis - amount_btc * 1e8
if change_amount > 0:
outputs.append({
'recipient_address': change_address,
'amount': change_amount
})
tx = {
'version': 1,
'inputs': inputs,
'outputs': outputs,
'locktime': 0
}
tx = sign_transaction(tx, private_key, utxos)
raw_tx = to_hex(tx)
print(raw_tx)
Please note that this is just an example, and you will need to replace the placeholders with your actual private key, recipient address, and amount of BTC. You will also need to implement the get_utxos()
, sign_transaction()
, and to_hex()
functions, as they are not included in the provided source code.
Finally, make sure to test the transaction with a small amount of BTC first to ensure that everything is working correctly before sending a large amount.
