EthereumKit

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

🚨 EthereumKit is currently under development. not ready for the production use 🚨

Features

How to Use

  • Generate seed and convert it to mnemonic sentence.
let entropy = Data(hex: "000102030405060708090a0b0c0d0e0f")
let mnemonic = Mnemonic.create(entropy: entropy)
print(mnemonic)
// abandon amount liar amount expire adjust cage candy arch gather drum buyer

let seed = Mnemonic.createSeed(mnemonic: mnemonic)
print(seed.toHexString())
  • PrivateKey and key derivation (BIP32)
let masterPrivateKey = PrivateKey(seed: seed, network: .main)

// m/44'
let purpose = masterPrivateKey.derived(at: 44, hardens: true)

// m/44'/60'
let coinType = purpose.derived(at: 60, hardens: true)

// m/44'/60'/0'
let account = coinType.derived(at: 0, hardens: true)

// m/44'/60'/0'/0
let change = account.derived(at: 0)

// m/44'/60'/0'/0
let firstPrivateKey = change.derived(at: 0)
print(firstPrivateKey.publicKey.address)
  • Create your wallet and generate addresse
// It generates master key pair from the seed provided.
let wallet = Wallet(seed: seed, network: .main)

let firstAddress = wallet.receiveAddress(at: 0)
// 0x83f1caAdaBeEC2945b73087F803d404F054Cc2B7

let secondAddress = wallet.receiveAddress(at: 1)
// 0xb3c3D923CFc4d551b38Db8A86BbA42B623D063cE

let thirdAddress = wallet.receiveAddress(at: 2)
// 0x82e35B34CfBEB9704E51Eb17f8263d919786E66a
