WalletKit

WalletKit is a Swift framwork that enables you to create and use bitcoin HD wallet(Hierarchical Deterministic Wallets) in your own app.

You can check if the address generation is working right here.

Features

• Mnemonic recovery phrease in BIP39
• BIP32/BIP44 HD wallet
• BIP13 address format

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, BIP44)

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.generateAddress(at: 0)
print(firstAddress)

let secondAddress = wallet.generateAddress(at: 1)
print(secondAddress)

let thirdAddress = wallet.generateAddress(at: 2)
print(thirdAddress)
