Binance DEX C# SDK

Binance DEX C# SDK

Source code is under MIT License (MIT)

C# SDK is inspired by Binance DEX Java SDK, (used a lot in previous Binance DEX "competition")

Project uses following NuGet packages:

• NBitcoin
• Google.Protobuf
• RestSharp
• Newtonsoft.Json
• WebsocketRPC.Standalone

SDK supports:

• Creating Wallets
• Creating Signature
• Broadcast to Binance DEX chain
• HTTP API (https://binance-chain.github.io/api-reference/dex-api/paths.html)
• WebSockets Streams (https://binance-chain.github.io/api-reference/dex-api/ws-streams.html)
• Node RPC (https://docs.binance.org/api-reference/node-rpc.html)

Wallet

Create wallet with private key string value either for TEST_NET or PROD:

    Wallet wallet = Wallet.FromPrivateKey(
        "6d3cfc67595db1523915219718a31fa5b467d099a51035d8fb82ea9841496f09",
        BinanceDexEnvironment.TEST_NET);

HttpApi

HttpApi objects:

• Times
• Infos
• Validator
• Peer
• Account
• AccountSequence
• Transaction
• Token
• Market
• FeeData
• MarketDepth
• TransactionMetadata
• KLines
• OrderList
• Order
• TickerStatistics
• TradePage
• TxPage

Broadcast objects:

• CancelOrder
• MultiTransfer
• NewOrder
• TokenFreeze
• TokenUnfreeze
• Transfer
• Vote

Example how to transfer founds:

    HttpApiClient httpApiClient = new HttpApiClient(BinanceDexEnvironment.TEST_NET);
    Wallet wallet = Wallet.FromPrivateKey(
        "6d3cfc67595db1523915219718a31fa5b467d099a51035d8fb82ea9841496f09",
        BinanceDexEnvironment.TEST_NET);

    Transfer transfer = new Transfer
    {
        Coin = "PND-943",
        FromAddress = wallet.Address,
        ToAddress = "tbnb18086qc9yxtk5ufddple8upf0k3072vvagpm2ml",
        Amount = "0.05"
    };

    TransactionRequest assmebler = new TransactionRequest(wallet, TransactionOption.DefaultInstace);
    string body = assmebler.BuildTransfer(transfer);
    List<TransactionMetadata> result = httpApiClient.Broadcast(body);

Web socket streams

Web socket stream objects:

• OrdersData
• AccountsData
• TransfersData
• TradesData
• MarketDiff
• MarketDepth
• KLine
• Ticker
• AllTickersData
• MiniTicker
• AllMiniTickersData
• Blockheight

Example how to listen web socket stream:

    public class Program
    {
        public static void Main(string[] args)
        {
            WebSocketClient client = new WebSocketClient();
            client.Env = BinanceDexEnvironment.TEST_NET;
            client.Topic = ETopic.Blockheight;
            client.StreamData += OnStreamData;
            client.Connect();

            Console.ReadLine();
        }

        private static void OnStreamData(object sender, IStreamData data)
        {
            Blockheight blockheight = (Blockheight)data;
            Console.WriteLine(blockheight.BlockHeight);
        }
    }

Node RPC

Node RPC endpoints and response objects:

• AbciInfo: ResponseData
• ConsensusState: ConsensusRoundStateData
• DumpConsensusState: DumpRoundStateData
• NetInfo: ResultNetInfo
• Genesis: ResultGenesis
• Health: ResultHealth
• NumUnconfirmedTxs: ResultUnconfirmedTxs
• Status: ResultStatus
• AbciQuery: ResultAbciQuery
• Block: ResultBlock
• BlockByHash: ResultBlock
• BlockResults: ResultBlockResults
• Blockchain: ResultBlockchainInfo
• Commit: ResultCommit
• ConsensusParams: ResultConsensusParams
• Tx: ResultTx
• TxSearch: ResultTxSearch
• UnconfirmedTxs: ResultUnconfirmedTxs
• Validators: ResultValidators
• BroadcastTxAsync: ResultBroadcastTx
• BroadcastTxCommit: ResultBroadcastTxCommit
• BroadcastTxSync: ResultBroadcastTx

Example how to communicate with Node RPC:

    NodeRpcClient nodeRpcClient = new NodeRpcClient("https://data-seed-pre-0-s1.binance.org");
    ResponseData responseData = nodeRpcClient.AbcInfo();
