1.轉(zhuǎn)帳usdt

/**
     * 轉(zhuǎn)賬
     * @param fromAddress 來源地址
     * @param fromHexPrivateKey 來源密鑰
     * @param toAddress 對方地址
     * @param amount 數(shù)量
     * @return 區(qū)塊鏈交易id
     */
    public static String transferUSDT(String fromAddress, String fromHexPrivateKey, String toAddress, BigInteger amount) {
        ApiWrapper client = getApiWrapper(fromHexPrivateKey);
        Function transfer =
                new Function(
                        "transfer",
                        Arrays.asList(new Address(toAddress), new Uint256(amount)),
                        Arrays.asList(new TypeReference<Bool>() {}));

        TransactionBuilder builder =
                client.triggerCall(fromAddress, TRC20_USDT_CONTRACT_ADDR, transfer);
        builder.setFeeLimit(50000000);

        Chain.Transaction transaction = client.signTransaction(builder.getTransaction());
        String txid = client.broadcastTransaction(transaction);
        client.close();
        return txid;
    }

2.轉(zhuǎn)帳 trx

/**
     * 轉(zhuǎn)賬TRX
     * @param fromAddress 來源地址
     * @param fromHexPrivateKey 來源 秘鑰
     * @param toAddress 目標(biāo)地址
     * @param amount 數(shù)量
     * @return
     * @throws IllegalException
     */
    public static String transferTRX( String fromAddress, String fromHexPrivateKey, String toAddress, long amount)
            throws IllegalException {
        ApiWrapper client = getApiWrapper(fromHexPrivateKey);
        Response.TransactionExtention transactionExtention =
                client.transfer(fromAddress, toAddress, amount);
        Chain.Transaction transaction = client.signTransaction(transactionExtention);
        String txid = client.broadcastTransaction(transaction);
        client.close();
        return txid;
    }

3.查詢交易狀態(tài)

/**
   * 查詢交易狀態(tài)
   *
   * @param txid
   * @return
   * @throws IllegalException
   */
  public String getTransactionStatusById(String txid) throws IllegalException {
    ApiWrapper client = getApiWrapper(tronServiceConfig.getHexPrivateKey());
    Chain.Transaction getTransaction = client.getTransactionById(txid);
    return getTransaction.getRet(0).getContractRet().name();
  }
