Get the library

How to use

• REST Endpoints // Get the ETH/USDT ticker via rest request var restClient = new BitfinexRestClient(); var tickerResult = await restClient.SpotApi.ExchangeData.GetTickerAsync("tETHUST"); var lastPrice = tickerResult.Data.LastPrice;
• Websocket streams // Subscribe to ETH/USDT ticker updates via the websocket API var socketClient = new BitfinexSocketClient(); var tickerSubscriptionResult = socketClient.SpotApi.SubscribeToTickerUpdatesAsync("tETHUST", (update) => { var lastPrice = update.Data.LastPrice; });

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

CryptoExchange.Net

Bitfinex.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.

Discord

A Discord server is available here. Feel free to join for discussion and/or questions around the CryptoExchange.Net and implementation libraries.
