# tokencore introduction

##### The core components of the blockchain wallet backend, support BTC, OMNI, ETH, ERC20, TRX, TRC20, BCH, BSV, DOGE, DASH, LTC

# tokencore usage


#### Introducing this library
gradle way
In your build.gradle
```
    repositories {
        maven { url 'https://jitpack.io' }
    }
    dependencies {
        compile 'com.github.paipaipaipai:tokencore:1.1.0'
    }
```

maven way
```
	<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>
```
#### Initialize identity
```java
    try {
        Files.createDirectories(Paths.get("${keyStoreProperties.dir}/wallets"))
    } catch (Throwable ignored) {
    }
//KeystoreStorage is an interface that implements its getdir method
    WalletManager.storage = KeystoreStorage();
    WalletManager.scanWallets();
    String password = "123456";
    Identity identity = Identity.GetCurrentIdentity ();
    if (identity == null) {
        Identity.createIdentity(
            "token",
            password,
            "",
            Network.MAINNET,
            Metadata.P2WPKH
        );
    }
```

#### Generate wallet

```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()
    );

```

#### Offline signature

```java
    String password ="123456";
    String toAddress ="dsadsadsadsa";
    int changeIdx =0;
    long amount =1000L;
    long fee =555L;
//utxos needs to go to the node or external api to get
    ArrayList<UTXO> utxos = new ArrayList();
    BitcoinTransaction bitcoinTransaction = BitcoinTransaction (
            toAddress,
    changeIdx,
    amount,
    fee,
    utxos
    );
    TxSignResult txSignResult = bitcoinTransaction.SignTransaction (
            ChainId.BITCOIN_MAINNET.toString(),
    password,
    wallet
    );
```
