This portal contains the official technical documentation for the kCoin project, including kUSD. kCoins are a family of stable-value cryptocurrencies that keep parity with fiat currencies using a system called the Kowala Protocol. More information and our technical whitepaper can be found on Kowala's website, kowala.tech.
The flagship kCoin is kUSD which, as its name suggests, is designed to keep parity with the US Dollar. This documentation assuming you're using kUSD, and will be updated as the project progresses. kUSD is currently in an alpha state (see the release roadmap) and not all of its documented features are implemented in their final form.
