RPC

• Setup
• Query Info
  • Get Account Info
  • Get Node Info
  • Query Transactions by Block
  • Query Blockmeta
  • Query Blockhash
  • Query Transaction Hash
• Post Transaction
  • Broadcast Transactions in commit manner
  • Broadcast Transactions in sync manner

Setup

• Create Default Node RPC Client

binanceDexNodeApi = BinanceDexApiClientFactory.newInstance().newNodeRpcClient();

• Create Customized Node RPC Client

binanceDexNodeApi = BinanceDexApiClientFactory.newInstance().newNodeRpcClient(baseUrl, hrp);

Query Info

Get Account Info

This function will query /abci_query rpc endpoint with input

String address = "tbnb16hywxpvvkaz6cecjz89mf2w0da3vfeg6z6yky2";
Account account = binanceDexNodeApi.getAccount(address);

Get Node Info

This function will query /status rpc endpoint

Infos nodeInfo = binanceDexNodeApi.getNodeInfo();

Query Transactions by Block

This function will query /tx_search rpc endpoint with indexer of tx.height

Long height = 7794210L;
List<Transaction> transactions = binanceDexNodeApi.getBlockTransactions(height);

You can get the type of a transaction,

String type = transactions.get(0).getTxType()

The following types are supported:

• NEW_ORDER
• CANCEL_ORDER
• FREEZE_TOKEN,
• UNFREEZE_TOKEN,
• TRANSFER,
• VOTE,
• ISSUE,
• BURN,
• MINT
• SUBMIT_PROPOSAL

Query Blockmeta

This function will query /block rpc endpoint

BlockMeta blockMeta = binanceDexNodeApi.getBlockMetaByHeight(8454149L);

Query Blockhash

This function will query /tx rpc endpoint

BlockMeta blockMeta = binanceDexNodeApi.getBlockMetaByHash("6FACD5586859B67AD5B5BABF0A0DC971AF91215DEBB9EF3D2F3847E4D2D97DDD");

Query Transaction Hash

This function will query /block_by_hash rpc endpoint

Transaction transaction = binanceDexNodeApi.getTransaction("9A4EFAEAC70A9115AD88B540FED7515D5DDBECF2BB19C0A7CBDC4E3F5053ECB8");

Post Transaction

Broadcast Transactions in commit manner

This function will post transactions to /broadcast_tx_commit rpc endpoint. It will be broadcasted and returns with the response from CheckTx and DeliverTx.

1. Transfer in a synchronized manner

//prepare transaction
String symbol = "BNB";
Transfer transfer = new Transfer();
transfer.setCoin(symbol);
transfer.setFromAddress(wallet.getAddress());
transfer.setToAddress("tbnb16hywxpvvkaz6cecjz89mf2w0da3vfeg6z6yky2");
transfer.setAmount("1.1");
TransactionOption options = new TransactionOption("test1gg", 1, null);
//post transaction
List<TransactionMetadata> resp = binanceDexNodeApi.transfer(transfer, wallet, options, true);

2. Multi-send in a synchronized manner

//prepare transaction

List<Output> outputs = new ArrayList<>();

List<OutputToken> outputTokens1 = new ArrayList<OutputToken>();
outputTokens1.add(new OutputToken("BNB", "0.1"));
outputTokens1.add(new OutputToken("XRP.B-585", "0.1"));
Output o1 = new Output("tbnb1mrslq6lhglm3jp7pxzlk8u4549pmtp9sgvn2rc", outputTokens1);

List<OutputToken> outputTokens2 = new ArrayList<OutputToken>();
outputTokens2.add(new OutputToken("BNB", "0.1"));
Output o2 = new Output("tbnb1sadf5e0gdpg757zefd6yru086cknjyttudg532", outputTokens2);

outputs.add(o1);
outputs.add(o2);

MultiTransfer multiTransfer = new MultiTransfer(wallet.getAddress(), outputs);
TransactionOption options = new TransactionOption("test", 1, null);

//post transaction
List<TransactionMetadata> resp = binanceDexNodeApi.multiTransfer(multiTransfer, wallet, options, true);

Broadcast Transactions in sync manner

This function will post transactions to /broadcast_tx_sync rpc endpoint. It will be broadcasted and returns with the response from CheckTx.

1. Transfer in a synchronized manner

//prepare transaction
String symbol = "BNB";
Transfer transfer = new Transfer();
transfer.setCoin(symbol);
transfer.setFromAddress(wallet.getAddress());
transfer.setToAddress("tbnb16hywxpvvkaz6cecjz89mf2w0da3vfeg6z6yky2");
transfer.setAmount("1.1");
TransactionOption options = new TransactionOption("test1gg", 1, null);
//post transaction
List<TransactionMetadata> resp = binanceDexNodeApi.transfer(transfer, wallet, options, false);

2. Multi-send in a synchronized manner

//prepare transaction

List<Output> outputs = new ArrayList<>();

List<OutputToken> outputTokens1 = new ArrayList<OutputToken>();
outputTokens1.add(new OutputToken("BNB", "0.1"));
outputTokens1.add(new OutputToken("XRP.B-585", "0.1"));
Output o1 = new Output("tbnb1mrslq6lhglm3jp7pxzlk8u4549pmtp9sgvn2rc", outputTokens1);

List<OutputToken> outputTokens2 = new ArrayList<OutputToken>();
outputTokens2.add(new OutputToken("BNB", "0.1"));
Output o2 = new Output("tbnb1sadf5e0gdpg757zefd6yru086cknjyttudg532", outputTokens2);

outputs.add(o1);
outputs.add(o2);

MultiTransfer multiTransfer = new MultiTransfer(wallet.getAddress(), outputs);
TransactionOption options = new TransactionOption("test", 1, null);

//post transaction
List<TransactionMetadata> resp = binanceDexNodeApi.multiTransfer(multiTransfer, wallet, options, false);
