TokenCore is a blockchain library. TokenCore provides the relatively consistent API that allows you to manage your wallets and sign transactions in BTC, ETH and EOS chains simultaneously. In addition, TokenCore introduces the concept of 'identity', you can use the same mnemonic to manage wallets on the three chains.
To install TokenCore, use CocoaPods and add this to your Podfile:
pod "TokenCore", git: "https://github.com/consenlabs/token-core-ios.git", branch: "master"
The example show how to manager the wallet and sign transaction, the eos sign will coming soon.
$ cd Example
$ pod install
// 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)")
}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:
