使用示例

生成钱包

创建钱包

  let keystore = EtherKeystore(keysSubfolder: "/keystore")
  let buildType: BuildType = .create(newPassword: [YOUR PASSWORD])
  keystore.buildWallet(type: buildType, completion: { (result) in
    print("wallet address: ", result.value, "or error: ", result.error)
  }

通过助记词导入

  let keystore = EtherKeystore(keysSubfolder: "/keystore")
  let buildType: BuildType = .mnemonic(words: [YOUR MNEMONICS WORDS ARRAY], newPassword: [YOUR PASSWORD])
  keystore.buildWallet(type: buildType, completion: { (result) in
    print("wallet address: ", result.value, "or error: ", result.error)
  }

通过私钥导入

  let keystore = EtherKeystore(keysSubfolder: "/keystore")
  let buildType: BuildType = .privateKey(privateKey: [YOUR PRIVATE KEY STRING], newPassword: [YOUR PASSWORD])
  keystore.buildWallet(type: buildType, completion: { (result) in
    print("wallet address: ", result.value, "or error: ", result.error)
  }

通过Keystore导入

  let keystore = EtherKeystore(keysSubfolder: "/keystore")
  let buildType: BuildType = .keystore(string: [YOUR KEYSTORE STRING], password: [YOUR PASSWORD], newPassword: [YOUR PASSWORD])
  keystore.buildWallet(type: buildType, completion: { (result) in
    print("wallet address: ", result.value, "or error: ", result.error)
  }

导出钱包

导出私钥

  let keystore = EtherKeystore(keysSubfolder: "/keystore")
  guard let wallet = keystore.wallet(for: [THE WALLET ADDRESS STRING]) else { return }
  let exportType: ExportType = .privateKey(wallet: wallet, password: [YOUR PASSWORD])
  keystore.exportWallet(type: exportType, completion: { (result) in
    print("exported keystore string: ", result.value, "or error: ", result.error)
  }

导出助记符

注：Loois SDK 不以任何方式存储用户的助记符

导出Keystore文件

  let keystore = EtherKeystore(keysSubfolder: "/keystore")
  guard let wallet = keystore.wallet(for: [THE WALLET ADDRESS STRING]) else { return }
  let exportType: ExportType = .keystore(wallet: wallet, password: [YOUR PASSWORD], newPassword: [YOUR PASSWORD])
  keystore.exportWallet(type: exportType, completion: { (result) in
    print("exported keystore string: ", result.value, "or error: ", result.error)
  }

修改Keystore密码

  let keystore = EtherKeystore(keysSubfolder: "/keystore")
  guard let wallet = keystore.wallet(for: [THE WALLET ADDRESS STRING]) else { return }
  keystore.update(wallet: wallet, password: [YOUR PASSWORD], newPassword: [YOUR PASSWORD], completion: { (result) in
    print("update result is: ", result.value, "or error: ", result.error)
  }

删除钱包

  let keystore = EtherKeystore(keysSubfolder: "/keystore")
  guard let wallet = keystore.wallet(for: [THE WALLET ADDRESS STRING]) else { return }
  keystore.delete(wallet: wallet, password: "12345678", completion: { (result) in
    print("delete result is: ", result.value, "or error: ", result.error)
  }

交易签名

  let keystore = EtherKeystore(keysSubfolder: "/keystore")
  guard let wallet = keystore.wallet(for: [THE WALLET ADDRESS STRING]) else { return }
  
  let contractAddress = EthereumAddress(string: [ADDRESS]) // WETH
  let encoder = FunctionRawEncoder.transfer(to: EthereumAddress(string: [ADDRESS])!,
                                        amount: 1_000_000_000_000_000)
  let st = RawTransaction(nonce: 539,
                       gasPrice: 5140490000,
                       gasLimit: 60000,
                          value: 0,
                             to: contractAddress,
                          data: encoder.encodedData,
                   functionRaw: encoder.function.signature)
  let signed = HomesteadSigner().sign(transaction: st, wallet: wallet, password: [YOUR PASSWORD])
  print("signed string: ", signed.value?.hexString, "or error: ", signed.error)
