bitcoinlib 0.6.11

Bitcoin and Other cryptocurrency Library

Bitcoin Crypto Currency Library for Python.

Includes a fully functional wallet, with multi signature, multi currency and multiple accounts. Use this library to create and manage transactions, addresses/keys, wallets, mnemonic password phrases and blocks with simple and straightforward Python code.

You this library at a high level and create and manage wallets for the command line or at a low level and create your own custom made transactions, keys or wallets.

The BitcoinLib connects to various service providers automatically to update wallets, transactions and blockchain information.

Install

Installed required packages

Example

The bitcoin library contains a wallet implementation using SQLAlchemy and SQLite3 to import, create and manage keys in a Hierarchical Deterministic way.

Example: Create wallet and generate new address (key) to receive bitcoins

>>> from bitcoinlib.wallets import Wallet
>>> w = Wallet.create('Wallet1')
>>> w.get_key().address
'1Fo7STj6LdRhUuD1AiEsHpH65pXzraGJ9j'

Now send a small transaction to your wallet and use the scan() method to update transactions and UTXO’s

>>> w.scan()
>>> w.info()  # Shows wallet information, keys, transactions and UTXO's

When your wallet received a payment and has unspent transaction outputs, you can send bitcoins easily. If successful a transaction ID is returned

>>> t = w.send_to('1PWXhWvUH3bcDWn6Fdq3xhMRPfxRXTjAi1', '0.001 BTC', offline=False)
'b7feea5e7c79d4f6f343b5ca28fa2a1fcacfe9a2b7f44f3d2fd8d6c2d82c4078'
>>> t.info  # Shows transaction information and send results
