Bit: Bitcoin made easy.

Version 0.7.2.

Bit is Python’s fastest Bitcoin library and was designed from the beginning to feel intuitive, be effortless to use, and have readable source code. It is heavily inspired by Requests and Keras.

Bit is so easy to use, in fact, you can do this:

>>> from bit import Key
>>> my_key = Key(...)
>>> my_key.get_balance('usd')
>>> # Let's donate!
>>> outputs = [
>>>     # Wikileaks
>>>     ('1HB5XMLmzFVj8ALj6mfBsbifRoD4miY36v', 0.0035, 'btc'),
>>>     # Internet Archive
>>>     ('1Archive1n2C579dMsAu3iC6tWzuQJz8dN', 190, 'jpy'),
>>>     # The Pirate Bay
>>>     ('129TQVAroeehD9fZpzK51NdZGQT4TqifbG', 3, 'eur'),
>>>     # xkcd
>>>     ('14Tr4HaKkKuC1Lmpr2YMAuYVZRWqAdRTcr', 2.5, 'cad')
>>> ]
>>> my_key.send(outputs)

Here is the transaction


  • Python’s fastest available implementation (100x faster than closest library)

  • Seamless integration with existing server setups

  • Supports keys in cold storage

  • Fully supports 25 different currencies

  • First class support for storing data in the blockchain

  • Deterministic signatures via RFC 6979

  • Access to the blockchain (and testnet chain) through multiple APIs for redundancy or a remote Bitcoin node

  • Exchange rate API, with optional caching

  • Optimal transaction fee API, with optional caching

  • Compressed public keys by default

  • Multiple representations of private keys; WIF, PEM, DER, etc.

  • Legacy P2PKH and Segwit nested-P2WPKH transactions

  • Legacy P2SH and Segwit nested-P2WSH transactions for multisignature

Dev Guide

Up ahead is Bit’s API and a few notes about design decisions. Beware the pedantry, or lack thereof.

Well done! There will be more soon, but right now you have nothing left to see. Remember, a watched pot never boils.
