Have you ever wanted to buy/sell cryptocurrency online? If yes, you most certainly have come across crypto exchanges. Since the day of the ICOs their number has grown tremendously.

Top cryptocurrency exchanges

The majority of the trades are still executed at the Top 10 cryptocurrency exchanges in the world. Just to list a few, by market cap:

  • - Binance
  • - OKEx
  • - Huobi
  • - Bit-Z
  • - DigiFinex
  • - Kraken


If you ever wanted to develop a product which tracks currency statistics, trades & orders, you have most certainly came across the issue that each cryptocurrency exchange has its own Public API integration process. This may become very tedious and time consuming.

Also, not to mention that often trade pairs or exchange symbols do not match across all exchanges causing additional complications for product development. Sometimes getting quotes, trades or order book information on demand or live is proves to be a quite costly as a skilled developers team needs to be in place.

Country codes, language codes, etc. are already standardized by ISO (International Organization for Standardization) while this is not applicable for Cryptocurrencies (at least for now). So imagine that you get “BTC-ETH” trade, which logically means that someone is selling BTC for ETH. Also this could mean, in some exchanges, that someone is selling ETH for BTC… the only right way to know is to read their documentation and hopefully it’s written there and it’s in English.

The consistency is an additional challenge, some exchanges provide only Rest API while others provide only WebSockets.

One additional issue is the cost of storing and processing historical data, we are talking about tens of TBs.
