BitcoinKit implements Bitcoin protocol in Swift. It is an implementation of the Bitcoin SPV protocol written (almost) entirely in swift.
- Send/receive transactions.
- See current balance in a wallet.
- Encoding/decoding addresses: P2PKH, WIF format.
- Transaction building blocks: inputs, outputs, scripts.
- EC keys and signatures.
- BIP32, BIP44 hierarchical deterministic wallets.
- BIP39 implementation.
