🗣 Wd提问: btctools

🤖 Ai回答: To create a command-line tool `btctools` for Bitcoin operations, follow this step-by-step guide、The tool will handle address generation, balance checks, and transaction sending using Python and essential libraries.

Step 1: Install Dependencies
bash
pip install requests bit

Step 2: Create the Python Script (`btctools.py`)
python
import argparse
import requests
from bit import PrivateKey, Key
from bit.network import NetworkAPI, set_service_timeout
from bit.utils import bytes_to_hex

Configure timeout for network requests
set_service_timeout(10)

def generate_address(testnet=False):
Generate a new Bitcoin address and return its private key (WIF) and public address.
key = Key(network='testnet' if testnet else 'bitcoin')
wif = key.to_wif()
address = key.address
return wif, address

def get_balance(address, testnet=False):
Retrieve the balance of a Bitcoin address (in satoshis) using a blockchain explorer API.
base_url = https://testnet.blockchain.info if testnet else https://blockchain.info
endpoint = f/q/addressbalance/{address}?confirmations=0
try:
response = requests.get(base_url + endpoint)
response.raise_for_status()
return int(response.text)
except requests.RequestException as e:
raise Exception(fFailed to fetch balance: {e})

def send_transaction(sender_wif, recipient_address, amount_btc, testnet=False):
Create, sign, and broadcast a Bitcoin transaction.
Initialize sender key
sender_key = PrivateKey(sender_wif, network='testnet' if testnet else 'bitcoin')

Convert BTC to satoshis
amount_sat = int(float(amount_btc) * 100_000_000)

Create and broadcast transaction
try:
tx_hash = sender_key.send(
[(recipient_address, amount_sat, 'satoshi')],
fee=500, Conservative fee rate (satoshis per byte)
absolute_fee=True
)
return tx_hash
except Exception as e:
raise Exception(fTransaction failed: {e})

def main():
parser = argparse.ArgumentParser(description=Bitcoin Command-Line Tools)
parser.add_argument(testnet, action=store_true, help=Use Bitcoin testnet)

subparsers = parser.add_subparsers(dest=command, required=True)

Subcommand: address
addr_parser = subparsers.add_parser(address, help=Generate a new Bitcoin address)

Subcommand: balance
bal_parser = subparsers.add_parser(balance, help=Check address balance)
bal_parser.add_argument(address, help=Bitcoin address)

Subcommand: send
send_parser = subparsers.add_parser(send, help=Send Bitcoin)
send_parser.add_argument(sender_key, help=Sender private key (WIF format))
send_parser.add_argument(recipient, help=Recipient Bitcoin address)
send_parser.add_argument(amount, help=Amount in BTC)

args = parser.parse_args()

try:
if args.command == address:
wif, address = generate_address(args.testnet)
print(fPrivate Key (WIF): {wif})
print(fAddress: {address})

elif args.command == balance:
satoshis = get_balance(args.address, args.testnet)
btc = satoshis / 100_000_000
print(fBalance: {btc:.8f} BTC)

elif args.command == send:
tx_hash = send_transaction(
args.sender_key,
args.recipient,
args.amount,
args.testnet
)
print(fTransaction ID: {tx_hash})

except Exception as e:
print(fError: {e})

if __name__ == __main__:
main()

Key Features
1、Address Generation:
Generates a new private key (WIF) and corresponding Bitcoin address.
Supports mainnet and testnet.

2、Balance Check:
Queries blockchain explorer APIs for real-time balance.
Displays balance in BTC with 8 decimal places.

3、Transaction Sending:
Constructs and broadcasts transactions via the network.
Automatically calculates fees and handles UTXOs.
Converts BTC amounts to satoshis internally.

Usage Examples

1、Generate a new address:
bash
python btctools.py address

For testnet:
bash
python btctools.py address testnet


2、Check balance:
bash
python btctools.py balance [address]

Example:
bash
python btctools.py balance 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa


3、Send Bitcoin:
bash
python btctools.py send [sender_wif] [recipient_address] [amount_btc]

Example:
bash
python btctools.py send L4gEfV..、1BvBMSE..、0.001


Notes
Testnet Mode: Use the `testnet` flag for testing (avoids spending real Bitcoin).
Error Handling: The tool provides clear error messages for issues like invalid keys, insufficient funds, or network problems.
Security: Private keys are processed locally and never transmitted externally.

This tool provides essential Bitcoin operations in a simple, secure, and user-friendly CLI format、Always exercise caution when handling real Bitcoin private keys!
