Getting Started

Rev. 27 June 2025

The Corastone platform is a distributed platform for digital securities lifecycle management, powered by a private and permissioned blockchain. All organizations that are part of this permissioned ecosystem run the same software (which is developed and distributed by Corastone) on their own Amazon Web Services (AWS) account. Each organization has an API integration point into the platform and can optionally have a set of web applications to be used as GUIs to interact with the platform.

Using This Guide

This Integration API Guide provides:

• basic flows for API calls

• a synopsis of each endpoint

• a link to the OpenAPI spec for each endpoint

• supporting content

Platform Roles and the Integration API

Multiple parties participate in transactions on the Corastone platform. For example, an asset manager and a fund administrator might make sequential calls to approve a posted balance. To clarify which calls are appropriate for which roles, we have added a prefix (using the following abbreviations) to the title of each method page.
