EthereumKit

EthereumKit is a Swift 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 HDWallet(seed: seed, network: .main)
let address = try wallet.generateAddress(at: 0)

// Send some ether
let rawTransaction = RawTransaction(ether: "0.15", address: "0x88b44BC83add758A3642130619D61682282850Df", nonce: 2)
let tx = try wallet.signTransaction(rawTransaction)

geth.sendRawTransaction(rawTransaction: tx) { result in 
    // Do something...
}
