EthereumKit

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

Features

  • Mnemonic recovery phrease in BIP39
  • BIP32/BIP44 HD wallet
  • EIP55 format address encoding
  • EIP155 replay attack protection
  • Sign transaction

How to Use

Wallet

  • BIP39: Generate seed and mnemonic sentence.
let entropy = Data(hex: "000102030405060708090a0b0c0d0e0f")
let mnemonic = Mnemonic.create(entropy: entropy)
let seed = Mnemonic.createSeed(mnemonic: mnemonic)
  • BIP32: Key derivation and address generation
// It generates master key pair from the seed provided.
let wallet = Wallet(seed: seed, network: .main)

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

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

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

Supported APIs

Geth in EthereumKit communicates with Ethereum via JSONRPC. It connects to Ropsten for test network and Mainnet for main network. (Will support localhost soon⚠️)

To see more about APIs, check the documentations.

Installation

Carthage

  • Insert github "yuzushioh/EthereumKit" to your Cartfile.
