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

• 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

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.

dotnet add package KrakenExchange.Net

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

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

Basic request:

// Get the ETH/USD ticker via rest request
var restClient = new KrakenRestClient();
var tickerResult = await restClient.SpotApi.ExchangeData.GetTickerAsync("ETHUSD");
var lastPrice = tickerResult.Data.First().Value.LastTrade.Price;

Place order:

var restClient = new KrakenRestClient(opts => {
	opts.ApiCredentials = new KrakenCredentials(
		new HMACCredential("SPOTKEY", "SPOTSECRET"),
		new HMACCredential("FUTURESKEY", "FUTURESSECRET")
	);
});

// Place Limit order to go long for 0.1 ETH at 2000
var orderResult = await restClient.FuturesApi.Trading.PlaceOrderAsync(
    "PF_ETHUSD",
    OrderSide.Buy,
    FuturesOrderType.Limit,
    0.1m,
    2000
    );

WebSocket subscription:

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

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

Kraken.Net includes AI-oriented documentation and examples for code generation tools:

See cryptoexchange-skills-hub for installable skills.

Kraken.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.
