Bitvavo.Net

The NuGet badges show "not found" until the first package publish — that is expected for this pre-release.

A high-performance .NET client library for the Bitvavo REST and WebSocket APIs, built on the CryptoExchange.Net base library.

This package is a community contribution, intended for adoption into the JKorf exchange-clients ecosystem alongside Binance.Net, Kraken.Net, Bybit.Net, etc. — same API patterns, same WebCallResult<T> discipline, same options shape, same DI extension surface.

The package targets net8.0;net9.0;net10.0 and is built on CryptoExchange.Net 11.1.1.

For information on the clients, dependency injection, response processing, and the shared interfaces, see the CryptoExchange.Net documentation.

Status

v0.3.0-preview:

• ✅ Public REST: GetMarketsAsync, GetKlinesAsync, GetServerTimeAsync, GetAssetsAsync, GetTickerPricesAsync, GetTickerBookAsync, GetTicker24hAsync, GetOrderBookAsync, GetPublicTradesAsync
• ✅ Public WebSocket: candles + trades subscriptions
• ✅ Signed REST (HMAC-SHA256) — Account (info / balances / fees), Trading (place / update / get / cancel / batch-cancel / open / history / fills), Funding (deposit address + history, withdrawal history, withdraw POST)
• ✅ Authenticated WebSocket: private account channel — subscribe to order-state + fill events

Supported features

Spot REST

API	Supported	Location
Public market data	✅	restClient.SpotApi.ExchangeData
Account	✅	restClient.SpotApi.Account
Trading	✅	restClient.SpotApi.Trading
Funding	✅	restClient.SpotApi.Account
Report (MiCA)	✅	restClient.SpotApi.Report
Institutional / subaccounts	✅	restClient.SpotApi.Institutional

Spot WebSocket

API	Supported	Location
Public streams	✅	socketClient.SpotApi.ExchangeData
Private account channel	✅	socketClient.SpotApi.Account

CryptoExchange.Net Shared interfaces

API	Supported	Location
Shared REST interfaces	✅	restClient.SpotApi.SharedClient
Shared socket interfaces	✅	socketClient.SpotApi.SharedClient

The package implements the full CryptoExchange.Net Shared-interface layer — 14 REST shared interfaces and 4 socket shared interfaces — so Bitvavo can be driven through the same exchange-agnostic abstractions as every other CryptoExchange.Net client.

Install

dotnet add package Bitvavo.Net --prerelease

Quick start — REST

using Bitvavo.Net.Clients;

using var client = new BitvavoRestClient();

var markets = await client.SpotApi.ExchangeData.GetMarketsAsync();
if (!markets.Success)
{
    Console.WriteLine($"Failed: {markets.Error}");
    return;
}

foreach (var m in markets.Data.Take(5))
{
    Console.WriteLine($"{m.Market}  status={m.Status}  pricePrecision={m.PricePrecision}");
}

Output:

ETH-EUR  status=trading  pricePrecision=5
BTC-EUR  status=trading  pricePrecision=2
...

Quick start — WebSocket

using var socketClient = new BitvavoSocketClient();
var sub = await socketClient.SpotApi.ExchangeData.SubscribeToKlineUpdatesAsync(
    "ETH-EUR", KlineInterval.OneMinute,
    update => Console.WriteLine($"{update.Data.Market}  close={update.Data.ClosePrice}"));

Quick start — signed REST

using Bitvavo.Net;
using Bitvavo.Net.Clients;
using Bitvavo.Net.Enums;
using Bitvavo.Net.Objects.Models.Spot;

using var client = new BitvavoRestClient(opts =>
    opts.ApiCredentials = new BitvavoCredentials(apiKey, apiSecret));

// Account info + balances
var info = await client.SpotApi.Account.GetAccountInfoAsync();
var balances = await client.SpotApi.Account.GetBalancesAsync();

// Place a limit buy order
var order = await client.SpotApi.Trading.PlaceOrderAsync(
    new BitvavoPlaceOrderRequest(
        "ETH-EUR", OrderSide.Buy, OrderType.Limit, OperatorId: 1,
        Amount: 0.5m, Price: 1500m, TimeInForce: TimeInForce.GoodTillCanceled));

Quick start — authenticated WebSocket

using var client = new BitvavoSocketClient(opts =>
    opts.ApiCredentials = new BitvavoCredentials(apiKey, apiSecret));

var sub = await client.SpotApi.Account.SubscribeToOrderUpdatesAsync(
    new[] { "ETH-EUR" },
    evt => Console.WriteLine($"order {evt.Data.OrderId} → {evt.Data.Status}"));

The framework runs Bitvavo's HMAC-SHA256 auth handshake automatically before dispatching the first authenticated subscription on the connection.

Smoke testing

The BitvavoSmoke exe (in Application/BitvavoSmoke) exercises every layer of the package out-of-the-box:

dotnet run --project Application/BitvavoSmoke                    # REST (markets + candles)
dotnet run --project Application/BitvavoSmoke -- --socket        # + public WebSocket subs
dotnet run --project Application/BitvavoSmoke -- --signed        # + signed REST: account / balances / order history
dotnet run --project Application/BitvavoSmoke -- --signed-ws     # + signed WebSocket: ETH-EUR private order/fill stream

The --signed and --signed-ws paths expect BITVAVO_API_KEY + BITVAVO_API_SECRET environment variables. The API key only needs the view capability for the smoke; trading + withdraw scopes are NOT exercised. Never check credentials into git.

Conventions

This library follows JKorf's exchange-client conventions exactly:

• Result type: every public method returns Task<WebCallResult<T>> (or Task<CallResult<UpdateSubscription>> for sockets) — never throws on protocol errors.
• Options: configure via new BitvavoRestClient(opts => { opts.RequestTimeout = ...; }).
• DI: register via services.AddBitvavo() — pooled HttpClient, transient REST client, singleton WebSocket client. Optional Action<BitvavoRestOptions> / Action<BitvavoSocketOptions> configurators.
• Naming: Bitvavo*RestClient*SpotApi*ExchangeData/Trading/Account mirrors Binance.Net etc.

Issues + PRs welcome. The eventual home for this package is JKorf/Bitvavo.Net — once the read-only surface is feature-complete and battle-tested, it will be submitted for adoption into JKorf's organisation.
