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 Kraken.Net documentation is the main resource for installing, configuring, and using the library.

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 more examples and explanations, continue with the Kraken.Net documentation or browse the compilable repository examples.

The CryptoExchange.Net Shared API V2 provides exchange-agnostic interfaces and models for common operations such as retrieving tickers, order books and balances, placing orders, and subscribing to market updates.
V2 uses a strict interface per capability. The SharedApi property on each API surface therefore exposes only the operations or subscriptions that surface actually supports. IKrakenSharedApiClient groups the exchange's Shared API surfaces for dependency injection and runtime capability lookup.
using Kraken.Net.Clients;
using CryptoExchange.Net.SharedApis;
using var restClient = new KrakenRestClient();
IGetTickerRest tickerClient = restClient.SpotApi.SharedApi;
var symbol = new SharedSymbol(TradingMode.Spot, "ETH", "USDT");
var result = await tickerClient.GetTickerAsync(
new GetTickerRequest(symbol));
if (!result.Success)
{
Console.WriteLine(result.Error);
return;
}
Console.WriteLine(result.Data.LastPrice);The request and response models belong to CryptoExchange.Net.SharedApis, so the same operation can accept another exchange's IGetTickerRest implementation. When using dependency injection, inject IKrakenSharedApiClient to access all of the exchange's Shared API surfaces or inject a capability such as IGetTickerRest directly. Use GetCapability on the aggregate when the operation, transport, or trading mode is selected at runtime.
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 provides shared access to different exchange APIs.
