.Mexc.Net Mexc.Net

.NET License

Mexc.Net is a strongly typed client library for accessing the Mexc REST and Websocket API.

Features

  • Response data is mapped to descriptive models
  • Input parameters and response values are mapped to discriptive enum values where possible
  • Automatic websocket (re)connection management
  • Client side rate limiting
  • Client side order book implementation
  • Support for managing different accounts
  • Extensive logging
  • Support for different environments
  • Easy integration with other exchange client based on the CryptoExchange.Net base library
  • Native AOT support

Supported Frameworks

The library is targeting both .NET Standard 2.0 and .NET Standard 2.1 for optimal compatibility

.NET implementation Version Support

Install the library

NuGet

NuGet version Nuget downloads

dotnet add package JK.Mexc.Net

GitHub packages

Mexc.Net is available on GitHub packages. You'll need to add https://nuget.pkg.github.com/JKorf/index.json as a NuGet package source.

Download release

GitHub Release

The NuGet package files are added along side the source with the latest GitHub release which can found here.

How to use

REST Endpoints

// Get the ETH/USDT ticker via rest request
var restClient = new MexcRestClient();
var tickerResult = await restClient.SpotApi.ExchangeData.GetTickerAsync("ETHUSDT");
var lastPrice = tickerResult.Data.LastPrice;

Websocket streams

// Subscribe to ETH/USDT ticker updates via the websocket API
var socketClient = new MexcSocketClient();
var tickerSubscriptionResult = socketClient.SpotApi.SubscribeToMiniTickerUpdatesAsync("ETHUSDT", (update) => 
{
  var lastPrice = update.Data.LastPrice;
});

For information on the clients, dependency injection, response processing and more see the Mexc.Net documentation or have a look at the examples here or here.

CryptoExchange.Net

Mexc.Net is based on the CryptoExchange.Net base library. Other exchange API implementations based on the CryptoExchange.Net base library are available and follow the same logic.

CryptoExchange.Net also allows for easy access to different exchange API's.

Discord

Nuget version
A Discord server is available here. Feel free to join for discussion and/or questions around the CryptoExchange.Net and implementation libraries.

AOT Support

Mexc websocket uses Protobuf serialization. The library uses the protobuf-net library to handle this, but unfortunately this library is not AOT compatible by itself.
To support AOT compilation:

  1. Add the rd.xml file to your application start project. File can be found here.
  2. In your application start project add a reference to the file with the following property in your .csproj file: <RdXmlFile Include="rd.xml" />
