tokencore使用方式

引入本库

• gradle方式 在你的build.gradle里面

    repositories {
        maven { url "https://dl.bintray.com/tronj/tronj" }
        maven { url 'https://jitpack.io' }
    }
    
    dependencies {
        compile 'com.github.paipaipaipai:tokencore:1.2.1'
    }

测试样例

初始化身份

    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

        Identity identity = Identity.getCurrentIdentity();
        String password = "123456";
        Wallet wallet = identity.deriveWalletByMnemonics(
        ChainType.BITCOIN,
        password,
        MnemonicUtil.randomMnemonicCodes()
        );
        System.out.println(wallet.getAddress());

        String password = "123456";
        String toAddress = "33sXfhCBPyHqeVsVthmyYonCBshw5XJZn9";
        int changeIdx = 0;
        long amount = 1000L;
        long fee = 555L;
        //utxos需要去节点或者外部api获取
        ArrayList<BitcoinTransaction.UTXO> utxos = new ArrayList();
        BitcoinTransaction bitcoinTransaction = new BitcoinTransaction(
        toAddress,
        changeIdx,
        amount,
        fee,
        utxos
        );
        Wallet wallet = WalletManager.findWalletByAddress(ChainType.BITCOIN, "33sXfhCBPyHqeVsVthmyYonCBshw5XJZn9");
        TxSignResult txSignResult = bitcoinTransaction.signTransaction(
        String.valueOf(ChainId.BITCOIN_MAINNET),
        password,
        wallet
        );
        System.out.println(txSignResult);

        String to = "TF17BgPaZYbz8oxbjhriubPDsA7ArKoLX3";
        long amount = 1;
        String password = "123456";
        Wallet wallet = WalletManager.findWalletByAddress(ChainType.BITCOIN, "TJRabPrwbZy45sbavfcjinPJC18kjpRTv8");
        TronTransaction transaction = new TronTransaction(from, to, amount);
        //离线签名，不建议签名和广播放一块
        TxSignResult txSignResult = transaction.signTransaction(String.valueOf(ChainId.BITCOIN_MAINNET), password, wallet);

        System.out.println(txSignResult);
