使用波场进行 转账、查询 java demo
otc、ctc。。。可用
1.转帐usdt /** * 转账 * @param fromAddress 来源地址 * @param fromHexPrivateKey 来源密钥 * @param toAddress 对方地址 * @param amount 数量 * @return 区块链交易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.转帐 trx /** * 转账TRX * @param fromAddress 来源地址 * @param fromHexPrivateKey 来源 秘钥 * @param toAddress 目标地址 * @param amount 数量 * @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.查询交易状态 /** * 查询交易状态 * * @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(); } 1.转帐usdt /**
