The Python BitcoinLib is a library that provides developers with a wide range of tools to work with Bitcoin.
- With BitcoinLib you can:
- Create and manage wallets
- Use various key-structures for your wallet such as HD (Hierarchical Deterministic) wallets following the BIP32 standard
- Interact with the Blockchain, retrieve and decode blockchain data
- Build, sign and verify transactions and signatures. This could be a standard segwit transactions but also multisig, nulldata or custom made transactions
- Create, analyse and run Bitcoin scripts
- Generate Bitcoin addresses and represent them in different address formats like P2PKH, P2SH, Bech32, etc
- Create private keys and work with Mnemonic password phrases
- Uses external Service providers to fetch address, transaction, utxo and blockchain data. Or connect to you local Bitcoin core, Bcoin or Blockbook node.
- Can be extended to support other cryptocurrencies by configuring custom parameters. At the moment Litecoin and Dogecoin are also supported.
Install required packages on Ubuntu or related Linux systems:
$ sudo apt install build-essential python3-dev libgmp3-dev
Then install using pip
$ pip install bitcoinlib
Check out the more detailed installation instructions to read how to install on other systems or for troubleshooting.
If you are using docker you can check some Dockerfiles to create images in the docker directory.

The bitcoin library contains a wallet implementation using SQLite3 or SQLAlchemy 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
'bc1qk25wwkvz3am9smmm3372xct5s7cwf0hmnq8szj'
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('bc1qemtr8ywkzg483g8m34ukz2l4pl3730776vzq54', '0.001 BTC', offline=False)
'b7feea5e7c79d4f6f343b5ca28fa2a1fcacfe9a2b7f44f3d2fd8d6c2d82c4078'
>>> t.info # Shows transaction information and send results
You can find many more examples in the documentation for instance about the Wallet.create() method.
There are many working examples on how to create wallets, specific transactions, encrypted databases, parse the blockchain, connect to specific service providers in the examples directory in the source code of this library.
Some more specific examples can be found on the Coineva website.
BitcoinLib is used at Blocksmurfer Explorer and many other repositories: https://github.com/1200wd/bitcoinlib/network/dependents
