EthereumKitSwift is a framework that enables you to create Ethereum wallet and use it in your app.

// BIP39: Generate seed and mnemonic sentence.

let mnemonic = Mnemonic.create()
let seed = Mnemonic.createSeed(mnemonic: mnemonic)

// BIP32: Key derivation and address generation

let wallet = try! Wallet(seed: seed, network: .main)

// Send some ether

let rawTransaction = RawTransaction(
    ether: try! Converter.toWei(ether: "0.00001"), 
    to: address, 
    gasPrice: Converter.toWei(GWei: 10), 
    gasLimit: 21000, 
    nonce: 0
)

let tx = try! wallet.signTransaction(rawTransaction)
print(tx)
