[![.NET](https://img.shields.io/github/actions/workflow/status/JKorf/BloFin.Net/dotnet.yml?style=for-the-badge)](https://github.com/JKorf/BloFin.Net/actions/workflows/dotnet.yml) ![License](https://img.shields.io/github/license/JKorf/BloFin.Net?style=for-the-badge)

BloFin.Net is a client library for accessing the [BloFin REST and Websocket API](https://docs.blofin.com/index.html). 

## Features

* Response data is mapped to descriptive models

* Input parameters and response values are mapped to discriptive enum values where possible

* High performance

* 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, as well as the latest dotnet versions to use the latest framework features.

|.NET implementation|Version Support|

|--|--|

|.NET Core|`2.0` and higher|

|.NET Framework|`4.6.1` and higher|

|Mono|`5.4` and higher|

|Xamarin.iOS|`10.14` and higher|

|Xamarin.Android|`8.0` and higher|

|UWP|`10.0.16299` and higher|

|Unity|`2018.1` and higher|

## Install the library

### NuGet 

[![NuGet version](https://img.shields.io/nuget/v/BloFin.net.svg?style=for-the-badge)](https://www.nuget.org/packages/BloFin.Net)  [![Nuget downloads](https://img.shields.io/nuget/dt/BloFin.Net.svg?style=for-the-badge)](https://www.nuget.org/packages/BloFin.Net)

	dotnet add package BloFin.Net

	

### GitHub packages

BloFin.Net is available on [GitHub packages](https://github.com/JKorf/BloFin.Net/pkgs/nuget/BloFin.Net). You'll need to add `https://nuget.pkg.github.com/JKorf/index.json` as a NuGet package source.

### Download release

[![GitHub Release](https://img.shields.io/github/v/release/JKorf/BloFin.Net?style=for-the-badge&label=GitHub)](https://github.com/JKorf/BloFin.Net/releases)

The NuGet package files are added along side the source with the latest GitHub release which can found [here](https://github.com/JKorf/BloFin.Net/releases).

## API key

For accessing authenticated endpoints an API key is required. When creating an API key in the BloFin web interface select `Connect to Third-Party Application` and select `JKorf` as the application name. BloFin requires users to select the application they're using with the API key. Selecting a different application will not work with the library.

## How to use

*Basic request:*

```csharp

// Get the ETH/USDT ticker via rest request

var restClient = new BloFinRestClient();

var tickerResult = await restClient.FuturesApi.ExchangeData.GetTickersAsync("ETH-USDT");

var lastPrice = tickerResult.Data.FirstOrDefault()?.LastPrice;

```

	

*Place order:*

```csharp

var restClient = new BloFinRestClient(opts => {

	opts.ApiCredentials = new BloFinCredentials("APIKEY", "APISECRET");

});

// Place Limit order to go long for 0.1 ETH at 2000

var orderResult = await restClient.FuturesApi.Trading.PlaceOrderAsync(

    "ETH-USDT",

    OrderSide.Buy,

    OrderType.Limit,

    0.1m,

    MarginMode.Cross,

    2000,

    positionSide: PositionSide.Long);

```

*WebSocket subscription:*

```csharp

// Subscribe to ETH/USDT ticker updates via the websocket API

var socketClient = new BloFinSocketClient();

var tickerSubscriptionResult = socketClient.FuturesApi.SubscribeToTickerUpdatesAsync("ETH-USDT", (update) => 

{

  var lastPrice = update.Data.LastPrice;

});

```

For information on the clients, dependency injection, response processing and more see the [documentation](https://cryptoexchange.jkorf.dev/client-libs/getting-started), or have a look at the examples [here](https://github.com/JKorf/BloFin.Net/tree/main/Examples) or [here](https://github.com/JKorf/CryptoExchange.Net/tree/master/Examples).

## CryptoExchange.Net

BloFin.Net is based on the [CryptoExchange.Net](https://github.com/JKorf/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](https://jkorf.github.io/CryptoExchange.Net#idocs_shared).
