HDWalletKit
HDWalletKit 是一个 Swift 框架，它可以让您在自己的应用程序中创建和使用比特币 HD 钱包（分层确定性钱包）。
特色功能
- 支持 HD 和 NonHD 钱包
- BIP39 中的助记词恢复短语
- 生成 Keystore 文件
- 读取 Keystore 文件
- 签署以太坊交易
- ERC20 令牌
- 基于 UTXO 签署交易
安装
CocoaPods
要使用 CocoaPods 将 HDWalletKit 集成到您的 Xcode 项目中，在您的 Podfile 中指定它
pod 'HDWalletKit'Carthage
使用 Carthage 进行安装，只需在你的 Cartfile 中添加以下内容

如何使用
生成种子并将其转换为助记词短语
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())私钥和密钥派生（BIP39）
let mnemonic = Mnemonic.create()
let seed = Mnemonic.createSeed(mnemonic: mnemonic)
let privateKey = PrivateKey(seed: seed, coin: .bitcoin)
// BIP44 key derivation
// m/44'
let purpose = privateKey.derived(at: .hardened(44))
// m/44'/0'
let coinType = purpose.derived(at: .hardened(0))
// m/44'/0'/0'
let account = coinType.derived(at: .hardened(0))
// m/44'/0'/0'/0
let change = account.derived(at: .notHardened(0))
// m/44'/0'/0'/0/0
let firstPrivateKey = change.derived(at: .notHardened(0))
print(firstPrivateKey.publicKey.address)生成密钥库文件
let data = "abandon amount liar amount expire adjust cage candy arch gather drum buyer"
let keystore = try! KeystoreV3(data: data, password: "qwertyui")
let encodedKeystoreDaya = (try? keystore?.encodedData())打开密钥库文件
let keystore = try! KeystoreV3(data: encodedKeystoreDaya, password: password)
guard let decoded = try? keystore?.getDecriptedKeyStore(password: password) else {
fatalError()
}
print(decoded)创建您的钱包和生成地址
let mnemonic = Mnemonic.create()
let seed = Mnemonic.createSeed(mnemonic: mnemonic)
let network: Network = .main(.bitcoin)
let wallet = Wallet(seed: seed, network: network)
let account = wallet.generateAccount()
print(account)使用私钥签名以太坊交易
let signer = EIP155Signer()
let rawTransaction1 = EthereumRawTransaction(
value: Wei("10000000000000000")!,
to: "0x34205555576717bBdF8158E2b2c9ed64EB1e6B85",
gasPrice: 99000000000,
gasLimit: 21000,
nonce: 2
)
guard let signed = try? signer.hash(rawTransaction: rawTransaction1).toHexString() else { return }
print(signed)使用私钥签名比特币交易
获取 UTXO 可使用 (https://github.com/essentiaone/essentia-bridges-api-ios)
let address = try LegacyAddress("1HLqrFX5fYwKriU7LRKMQGhwpz5HuszjnK", coin: .bitcoin)
let utxoWallet = UTXOWallet(privateKey: "Kz9UKkL6bKE92QPxQbPcqkCZTnCyLVyfRNFRSbToNjyb4bx321fh")
let signedTx = try utxoWallet.createTransaction(to: address, amount: 0, utxos: utxos)创建发送 ERC20 代币交易数据
let erc20Token = ERC20(contractAddress: "0x8f0921f30555624143d427b340b1156914882c10", decimal: 18, symbol: "ESS")
let address = "0x2f5059f64D5C0c4895092D26CDDacC58751e0C3C"
let data = try! erc20Token.generateDataParameter(toAddress: address, amount: "3") 创建获取 ERC20 代币余额交易数据
let erc20Token = ERC20(contractAddress: "0x8f0921f30555624143d427b340b1156914882c10", decimal: 18, symbol: "ESS")
let data = try! erc20Token.generateGetBalanceParameter(toAddress: "2f5059f64D5C0c4895092D26CDDacC58751e0C3C")将非 HD 私钥转换为地址
let privateKey = PrivateKey(pk: "L35qaFLpbCc9yCzeTuWJg4qWnTs9BaLr5CDYcnJ5UnGmgLo8JBgk", coin: .bitcoin)
print(privateKey.publicKey.address)
