Test sample

Initialize identity

 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

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

Offline signature

 String password = "123456";
 String toAddress = "33sXfhCBPyHqeVsVthmyYonCBshw5XJZn9";
 int changeIdx = 0;
 long amount = 1000L;
 long fee = 555L;
 //utxos needs to go to the node or external api to get
 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 from = "TJRabPrwbZy45sbavfcjinPJC18kjpRTv8";
 String to = "TF17BgPaZYbz8oxbjhriubPDsA7ArKoLX3";
 long amount = 1;
 String password = "123456";
 Wallet wallet = WalletManager.findWalletByAddress(ChainType.BITCOIN, "TJRabPrwbZy45sbavfcjinPJC18kjpRTv8");
 TronTransaction transaction = new TronTransaction(from, to, amount);
 //Offline signature, it is not recommended to sign and broadcast together
 TxSignResult txSignResult = transaction.signTransaction(String.valueOf(ChainId.BITCOIN_MAINNET), password, wallet);
 System.out.println(txSignResult);
