TokenCore

TokenCore 是一个区块链库。TokenCore 提供了相对一致的 API，允许您同时管理 BTC、ETH 和 EOS 链上的钱包以及签署交易。此外，TokenCore 引入了“身份”的概念，您可以使用同样的助记词来管理三个链上的钱包。

安装

要安装 TokenCore，请使用 CocoaPods 并在 Podfile 中添加以下内容

pod "TokenCore", :git => "[email protected]:consenlabs/token-core-ios.git", :branch => 'master'

尝试 API

创建新身份并推导出 eth、btc 钱包

// You should create or recover Identity first before you create other wallets
do {
  var metadata = WalletMeta(source: .newIdentity)
  metadata.network = Network.mainnet
  metadata.segWit = .p2wpkh // .p2wpkh means that the derived btc wallet is a SegWit wallet
  metadata.name = "MyFirstIdentity"
  let (mnemonic, identity) = try Identity.createIdentity(password: TestData.password, metadata: metadata)
  let ethereumWallet = identity.wallets[0]
  let bitcoinWalelt = identity.wallets[1]
} catch {
  print("createIdentity failed, error:\(error)")
}

导出钱包

let prvKey = try WalletManager.exportPrivateKey(walletID: ethereumWallet.walletID, password: TestData.password)
print("PrivateKey: \(prvKey)")
let mnemonics = try WalletManager.exportMnemonic(walletID: ethereumWallet.walletID, password: TestData.password)
print("Mnemonic: \(mnemonics)")
let keystore = try WalletManager.exportKeystore(walletID: ethereumWallet.walletID, password: TestData.password)
print("Keystore: \(keystore)")

// output:
// PrivateKey: f653be3f639f45ea1ed3eb152829b6d881ce62257aa873891e06fa9569a8d9aa
// Mnemonic: tide inmate cloud around wise bargain celery cement jungle melody galaxy grocery
// Keystore: {"id":"c7575eba-3ae3-4cc3-86ba-2eb9c6839cad","version":3,"crypto":{"ciphertext":"7083ba3dd5470ba4be4237604625e05fa6b668954d270beb848365cbf6933ec5","mac":"f4f9ea8d42ff348b11fc146c396da446cc975309b3538e08a58c0b218bddd15d","cipher":"aes-128-ctr","cipherparams":{"iv":"db3f523faf4da4f1c6edcd7bc1386879"},"kdf":"pbkdf2","kdfparams":{"dklen":32,"c":10240,"prf":"hmac-sha256","salt":"0ce830e9f888dfe33c31e6cfc444d6f588161c9d4128d4066ee5dfdcbc5d0079"}},"address":"4a1c2072ac67b616e5c578fd9e2a4d30e0158471"}

签名交易

let signResult = WalletManager.ethSignTransaction(
        walletID: String,
        nonce: String,
        gasPrice: String,
        gasLimit: String,
        to: String,
        value: String,
        data: String,
        password: String,
        chainID: Int
      )
let signedTx = signResult.signedTx // This is the signature result which you need to broadcast.
let txHahs = signResult.txHash // This is txHash which you can use for locating your transaction record

故障排除

由于 Xcode 命令行工具不再安装到 /usr/include，因此在 macOS 10.14 Mojave 和 Xcode 10 上，请安装 /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg。
