Trading features will be added in the future. This SDK covers the Gemini, GDAX, Bitfinex, Poloniex, Binance, Kraken, Cryptopia, Koinex, BitGrail, and CoinMarketCap APIs.
PotCoin first introduced its blockchain-based cryptocurrency to help streamline access to participation in the quickly legalizing marijuana industry. To help developers aid in that process, PotCoin offered limited access to its Payment API. Now, the company has released full access to the API.
