CryptoClients.Net provides unified access to cryptocurrency trading APIs in C#.

It combines:

  • direct access to exchange-specific REST and WebSocket clients
  • shared cross-exchange interfaces from CryptoExchange.Net
  • dynamic multi-exchange requests and subscriptions
  • client-side helpers such as rate limiting, order books, trackers, and user client management

The library currently supports 27 exchanges and additional platform integrations such as CoinGecko and Polymarket.

Features

  • Full access to exchange-specific APIs through ExchangeRestClient and ExchangeSocketClient
  • Shared exchange-agnostic interfaces for spot and futures functionality
  • Request data from a single exchange or many exchanges in one call
  • Subscribe to one or many data streams on multiple exchanges through a single API
  • Strongly typed models and enum mappings
  • Automatic WebSocket (re)connection management
  • Client-side rate limiting
  • Client-side order book support
  • Multi-user client management
  • Support for multiple API environments
  • Dynamic credential management

Quick example

var client = new ExchangeRestClient();
var symbol = new SharedSymbol(TradingMode.Spot, "ETH", "USDT");

var results = await client.GetSpotTickerAsync(
    new GetTickerRequest(symbol),
    ["Binance", "Bybit", "HyperLiquid", "OKX"]);

foreach (var result in results)
{
    if (!result.Success)
        Console.WriteLine($"{result.Exchange} error: {result.Error}");
    else
        Console.WriteLine($"{result.Exchange} price: {result.Data.LastPrice}");
}

Installation

NuGet

dotnet add package CryptoClients.Net

GitHub Packages

CryptoClients.Net is also available on GitHub Packages.

Add the following NuGet source:

https://nuget.pkg.github.com/JKorf/index.json

Download release

Latest releases are available here:
https://github.com/JKorf/CryptoClients.Net/releases

Getting started

There are two main entry points:

  • ExchangeRestClient for REST APIs
  • ExchangeSocketClient for WebSocket APIs

You can also use exchange-specific clients directly, such as BinanceRestClient or KucoinSocketClient.

Dependency injection

// Load options from configuration
builder.Services.AddCryptoClients(builder.Configuration.GetSection("CryptoClients"));

// Or configure in code
builder.Services.AddCryptoClients(options =>
{
    options.OutputOriginalData = true;
});

// Inject later
public class TradingBot
{
    public TradingBot(IExchangeRestClient restClient, IExchangeSocketClient socketClient)
    {
    }
}

Direct construction

IExchangeRestClient restClient = new ExchangeRestClient();
IExchangeSocketClient socketClient = new ExchangeSocketClient();

IBinanceRestClient binanceRestClient = new BinanceRestClient();
IKucoinSocketClient kucoinSocketClient = new KucoinSocketClient();

Configuration

Clients can be configured globally, per exchange, or both.

builder.Services.AddCryptoClients(globalOptions =>
{
    globalOptions.OutputOriginalData = true;
    globalOptions.ApiCredentials = new ExchangeCredentials
    {
        Binance = new BinanceCredentials("BinanceKey", "BinanceSecret"),
        Kucoin = new KucoinCredentials("KucoinKey", "KucoinSecret", "KucoinPassphrase"),
        OKX = new OKXCredentials("OKXKey", "OKXSecret", "OKXPassphrase")
    };
},
bybitRestOptions: bybitOptions =>
{
    bybitOptions.Environment = Bybit.Net.BybitEnvironment.Eu;
    bybitOptions.ApiCredentials = new BybitCredentials("BybitKey", "BybitSecret");
});

Environment selection can also be configured through GlobalExchangeOptions.ApiEnvironments.

More configuration details are available in the documentation:
https://cryptoexchange.jkorf.dev/crypto-clients/options

Usage patterns

1. Exchange-specific clients

Use the exchange libraries directly when full exchange-specific functionality is needed.

var kucoinClient = new KucoinRestClient();
var binanceClient = new BinanceRestClient();

var binanceTicker = await binanceClient.SpotApi.ExchangeData.GetTickerAsync("ETHUSDT");
var kucoinTicker = await kucoinClient.SpotApi.ExchangeData.GetTickerAsync("ETH-USDT");

2. Exchange clients through the main client

Use ExchangeRestClient or ExchangeSocketClient as a single entry point.

var client = new ExchangeRestClient();

var binanceTicker = await client.Binance.SpotApi.ExchangeData.GetTickerAsync("ETHUSDT");
var kucoinTicker = await client.Kucoin.SpotApi.ExchangeData.GetTickerAsync("ETH-USDT");

3. Shared client interfaces

Use shared interfaces for exchange-agnostic logic.

async Task<ExchangeWebResult<SharedSpotTicker>> GetTickerAsync(ISpotTickerRestClient client, SharedSymbol symbol)
    => await client.GetSpotTickerAsync(new GetTickerRequest(symbol));

var client = new ExchangeRestClient();
var symbol = new SharedSymbol(TradingMode.Spot, "ETH", "USDT");

var binanceResult = await GetTickerAsync(client.Binance.SpotApi.SharedClient, symbol);
var kucoinResult = await GetTickerAsync(client.Kucoin.SpotApi.SharedClient, symbol);

4. Multi-exchange requests

Request the same data from multiple exchanges in one call.

var client = new ExchangeRestClient();
var symbol = new SharedSymbol(TradingMode.Spot, "ETH", "USDT");

var tickers = await client.GetSpotTickerAsync(
    new GetTickerRequest(symbol),
    [Exchange.Binance, Exchange.Kucoin, Exchange.OKX]);

WebSocket subscriptions

The socket client also supports single-exchange and multi-exchange subscriptions.

var socketClient = new ExchangeSocketClient();
var symbol = new SharedSymbol(TradingMode.Spot, "ETH", "USDT");

var subscriptions = await socketClient.SubscribeToTickerUpdatesAsync(
    new SubscribeTickerRequest(symbol),
    data => Console.WriteLine($"{data.Data.Symbol} {data.Data.LastPrice}"),
    [Exchange.Binance, Exchange.OKX]);

Multiple users

Use ExchangeUserClientProvider when working with multiple users and isolated client instances.

var provider = new ExchangeUserClientProvider();
var user1Credentials = new ExchangeCredentials
{
    Binance = new BinanceCredentials("key", "secret")
};
var user2Credentials = new ExchangeCredentials
{
    Binance = new BinanceCredentials("key", "secret")
};

var restClientUser1 = provider.GetRestClient("user-1", user1Credentials);
var restClientUser2 = provider.GetRestClient("user-2", user2Credentials);
var socketClientUser1 = provider.GetSocketClient("user-1");

Metadata and discovery

Use:

  • Platforms.All for supported exchanges and additional platforms

Example API

The following minimal API exposes a cross-exchange ticker endpoint:

using CryptoClients.Net.Interfaces;
using CryptoExchange.Net.Objects;
using CryptoExchange.Net.SharedApis;
using Microsoft.AspNetCore.Mvc;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddCryptoClients();

var app = builder.Build();

app.MapGet("Ticker/{exchange}/{baseAsset}/{quoteAsset}",
    async ([FromServices] IExchangeRestClient client, string exchange, string baseAsset, string quoteAsset) =>
    {
        var spotClient = client.GetSpotTickerClient(exchange)!;
        var result = await spotClient.GetSpotTickerAsync(
            new GetTickerRequest(new SharedSymbol(TradingMode.Spot, baseAsset, quoteAsset)));

        return result.Data;
    });

app.Run();

Example requests:

  • GET /Ticker/Kraken/ETH/BTC
  • GET /Ticker/Kucoin/BTC/USDT
