Kraken.Net is a strongly typed client library for accessing the Kraken REST and Websocket API. All data is mapped to readable models and enum values. Additional features include an implementation for maintaining a client side order book, easy integration with other exchange client libraries and more.

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

dotnet add package KrakenExchange.Net

REST Endpoints

// 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;

Websocket streams

// 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.LastTrade.Price;
});

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

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.
