## Introduction



EtherWalletKit is an Ethereum Wallet Toolkit for iOS.



I hope cryptocurrency and decentralized token economy become more widely adapted.

However, some developers hesitate to add a crypto wallet on apps since blockchain and cryptocurrency are complex and require many new knowledge. 



Don't worry. 
With EtherWalletKit, you can implement an Ethereum wallet without a server and blockchain knowledge.

* BIP39 Mnemonics

#### Planned Features

* Browsing transaction history 

* Keystore import / export

* Custom configuration / advanced transactions

* Multiple accounts

* Third party APIs

* ERC-721 supports



## Installation



### CocoaPods



To integrate EtherWalletKit into your Xcode project using CocoaPods, specify it in your Podfile:



pod 'EtherWalletKit'



## Quick Start



#### 0. Don't forget to import it



``` swift



import EtherWalletKit



```



#### 1. Create an Ethereum Wallet



```swift

// Generate a new account with its new password.

try? EtherWallet.account.generateAccount(password: "ABCDEFG")



// Import an existing account from its private key and set its new password.

try? EtherWallet.account.importAccount(privateKey: "1dcbc1d6e0a4587a3a9095984cf051a1bc6ed975f15380a0ac97f01c0c045062, password: "ABCDEFG")

```



Note: ```password``` will be encrypted and saved to the device and it will be required to access the wallet.



#### 2. Get balance



```swift

// Get balance of Ether

EtherWallet.balance.etherBalance { balance in

    print(balance)

}



// Get balance of a token

EtherWallet.balance.tokenBalance(contractAddress: "0xd26114cd6EE289AccF82350c8d8487fedB8A0C07") { balance in

    print(balance)

}

```



#### 3. Send



```swift

// send Ether to an address.

EtherWallet.transaction.sendEther(to: "0x7777787C97a35d37Db8E5afb0C92BCfd4F6480bE", amount: "1.5", password: "ABCDEFG") { txHash in

    print(txHash)

}



// send a token to an address.

EtherWallet.transaction.sendToken(to: "0x7777787C97a35d37Db8E5afb0C92BCfd4F6480bE", contractAddress: "0xd26114cd6EE289AccF82350c8d8487fedB8A0C07", amount: "20", password: "ABCDEFG", decimal: 18) { txHash in

    print(txHash)

}

```



Note: ```password``` should be eqaul to the password of wallet created. Also you can put ```gasPrice``` as an extra parameter to set gas price for the transcation.



For full documentation, please see [THIS](./Docs/Document.md).



## Notes



* Nothing will be sent to a server. Everything will be worked on the local device and Ethereum Blockchain.

* You dont need to download and sync the nodes because [Infura](https://infura.io/) is doing it for you.

* ```password``` for wallet is equal to the password for the keystore file. Always make sure a ```password``` is long enough for security.
