# tokencore介绍

##### 区块链钱包后台核心组件，支持BTC,OMNI,ETH,ERC20,TRX,TRC20,BCH,BSV,DOGE,DASH,LTC

# tokencore使用方式

#### 引入本库
gradle方式
在你的build.gradle里面
```
    repositories {
        maven { url 'https://jitpack.io' }
    }
    
    dependencies {
        compile 'com.github.paipaipaipai:tokencore:1.1.0'
    }
```
maven方式
```
	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>
	
	<dependency>
	    <groupId>com.github.paipaipaipai</groupId>
	    <artifactId>tokencore</artifactId>
	    <version>1.1.0</version>
	</dependency>
```

#### 初始化身份
```java
    try {
        Files.createDirectories(Paths.get("${keyStoreProperties.dir}/wallets"))
        } catch (Throwable ignored) {
        }
//KeystoreStorage是接口，实现它的getdir方法
        WalletManager.storage = KeystoreStorage();
        WalletManager.scanWallets();
        String password = "123456";
        Identity identity = Identity.getCurrentIdentity ();
        if (identity == null) {
        Identity.createIdentity(
        "token",
        password,
        "",
        Network.MAINNET,
        Metadata.P2WPKH
        );
        }
```

#### 生成钱包

```java
    Identity identity = Identity.getCurrentIdentity ()
        String password ="123456";
        List<String> chainTypes = new ArrayList();
        chainTypes.add(ChainType.BITCOIN);

        List<Wallet> wallets = identity.deriveWalletsByMnemonics (
        chainTypes,
        password,
        MnemonicUtil.randomMnemonicCodes()
        );

```

#### 离线签名

```java
    String password ="123456";
        String toAddress ="dsadsadsadsa";
        int changeIdx =0;
        long amount =1000L;
        long fee =555L;
//utxos需要去节点或者外部api获取
        ArrayList<UTXO> utxos = new ArrayList();
        BitcoinTransaction bitcoinTransaction = BitcoinTransaction (
        toAddress,
        changeIdx,
        amount,
        fee,
        utxos
        );
        TxSignResult txSignResult = bitcoinTransaction.signTransaction (
        ChainId.BITCOIN_MAINNET.toString(),
        password,
        wallet
        );
```
