                        The BitcoinKit library is a Swift implementation of the Bitcoin(BCH/BTC) protocol. This library was originally made by Katsumi Kishikawa, and now is maintained by Yenom Inc. It allows maintaining a wallet and sending/receiving transactions without needing a full blockchain node. It comes with a simple wallet app showing how to use it.
