# Open USD (OUSD) developer reference > Independent documentation for Open USD (OUSD), the payments stablecoin created by Open Standard. This reference concerns Open Standard’s OUSD. It is unrelated to Pixar’s Universal Scene Description (OpenUSD) and Origin Dollar (also called OUSD). Start with Concepts, choose a task, then read the provider and network references. Product support, account eligibility, network availability, and testing status are separate facts. For accurate reuse, preserve the meaning of source limitations; illustrative code is not a tested integration. Markdown copies are generated from the same rendered pages as this website. Each copy identifies its original URL; links and section fragments point to the original pages. The JSON dataset is linked below and remains the structured source for providers, products, networks, addresses, and provenance. ## Concepts - [What is Open USD (OUSD)?](https://openusd.dev/guides/what-is-open-usd.md): The OUSD stablecoin: issuer, networks, governance, and the names to keep apart.
