java usdt交易监听 代码

由于您没有提供更多的上下文，我将提供一个简单的Java代码示例来监听USDT交易：

import org.bitcoinj.core.*;
import org.bitcoinj.kits.WalletAppKit;
import org.bitcoinj.params.MainNetParams;
import org.bitcoinj.script.Script;
import org.bitcoinj.script.ScriptBuilder;

public class USDTTransactionListener {
    public static void main(String[] args) throws Exception {
        // Create a new wallet app kit
        NetworkParameters params = MainNetParams.get();
        WalletAppKit kit = new WalletAppKit(params, new java.io.File("."), "mywallet");

        // Add a listener to the kit
        kit.wallet().addEventListener((wallet, tx, txType, depth) -> {
            // Check if the transaction is a USDT transaction
            for (TransactionOutput output : tx.getOutputs()) {
                Script script = output.getScriptPubKey();
                if (script.isSentToAddress() && script.getToAddress(params) != null) {
                    if (script.isOpReturn() && script.getChunks().size() > 1) {
                        byte[] data = script.getChunks().get(1).data;
                        if (data != null && data.length >= 4 &&
                                data[0] == 'o' && data[1] == 'm' && data[2] == 'n' && data[3] == 0) {
                            // This is a USDT transaction, do something with it
                            System.out.println("USDT transaction detected: " + tx.getHashAsString());
                        }
                    }
                }
            }
        });

        // Start the kit and wait for it to finish initializing
        kit.startAsync();
        kit.awaitRunning();

        // Wait for the user to exit
        System.out.println("Press enter to exit");
        System.in.read();

        // Stop the kit
        kit.stopAsync();
        kit.awaitTerminated();
    }
}

该代码使用BitcoinJ库来监听比特币网络上的交易。它会检查输出脚本的类型，以确定它是否是一个USDT交易。如果是，它将打印出交易哈希。请注意，这个代码还没有处理USDT交易的金额或其他细节。
