CryptoExchange.Net

CryptoExchange.Net is a base library which is used to implement different cryptocurrency (exchange) API's. It provides a standardized way of implementing different API's, which results in a very similar experience for users of the API implementations. Note that the CryptoExchange.Net package itself can not be used directly for accessing API's. Either install a client library from the list below or use CryptoClients.Net which includes access to all exchange API's.

For more information on what CryptoExchange.Net and it's client libraries offers see the Documentation.

Current implementations

The following API's are directly supported. Note that there are 3rd party implementations going around, but only these are created and supported by me:

Exchange	Repository	Nuget
Binance	JKorf/Binance.Net
BingX	JKorf/BingX.Net
Bitfinex	JKorf/Bitfinex.Net
Bitget	JKorf/Bitget.Net
BitMart	JKorf/BitMart.Net
Bybit	JKorf/Bybit.Net
Coinbase	JKorf/Coinbase.Net
CoinEx	JKorf/CoinEx.Net
CoinGecko	JKorf/CoinGecko.Net
Crypto.com	JKorf/CryptoCom.Net
Gate.io	JKorf/GateIo.Net
HTX	JKorf/HTX.Net
Kraken	JKorf/Kraken.Net
Kucoin	JKorf/Kucoin.Net
Mexc	JKorf/Mexc.Net
OKX	JKorf/OKX.Net
WhiteBit	JKorf/WhiteBit.Net

Any of these can be installed independently or install CryptoClients.Net which includes all exchange API's.
