Great questions, thanks! The API is currency agnostic, so one account can have many balances from multiple currencies attached to it. However, you can't do transactions cross currencies at the moment. You can do it on your side, and use the API to store the result, both normalized and Selinger are doable. I definitely plan to add this at some point, thanks for the reference, it's great! On the tech side, the service is written in Go, and the database is DynamoDB, everything runs on AWS right now. I'm planning to add support for Cassandra and MongoDB, as some enterprise customers want to run it inside their datacenters.
