The exchange rate is defined here as the exchange rate between VELO token and a particular stable credit. The exchange rate is determined by the price (in stable credit's pegged currency) which VELO token is sold at an exchange. We aim to support as many currencies as possible, but the limitation will be the availability of price data.
When calculating price, we only use prices that are "fresh". We define price as “fresh” only if it was updated in the last 15 minutes.
The price output is the amount of VELO token exchangeable per 1 unit of specified assetCode.
