sequence

Two great points. The amounts are actually integer, the same pattern used by Stripe and others. See it here: https://github.com/decimals/sequence/blob/master/src/decimal... I'm working on enabling idempotent requests, should come out next week. I'm using the same pattern used by Stripe as well (big fan). An optional `x-request-id` header that will ensure only once processing if present. This is very important to enable consistency over the network with other services using the ledger.

Was my top question as well, but note the underlying DB is Dynamo, which supports transactions, and a quick peek at the code looks like it's using them as intended (I don't know closure and it's been ages since I've used Dynamo so take with a grain of salt). https://github.com/decimals/sequence/blob/master/src/decimal...
