Background
As cryptocurrencies gain popularity there's increasing interest from larger institutions. To source liquidity there are a multitude of independent crypto exchanges, such as FTX, Kraken and Coinbase.
Problem
Facilitating institutional crypto trading typically requires pooling liquidity from multiple exchanges. Executing trades and managing ledgers across multiple websites can be cumbersome.
Solution
Utilise the exchange developer API's to build an 'exchange aggregator' using a distributed microservices architecture and the GO programming language. Applications can then be built for order routing, viewing aggregate exchange balances etc.
Below is a short demo of the SK7 crypto-exchange aggregator. It shows the FTX and Kraken order books combined into a single order book.
