Build against OPRP

Three SDKs.
One exchange contract.

SDKs handle protected exchange, discovery, grants and refresh, clinical operations, ordered queues, durable mirrors, callbacks and portable archives.

Start with the reference Host

The developer lab runs two persistent Hosts with synthetic identities and verified development HTTPS. Build a client against the exchange endpoint, then test outages, retries and portability.

The .NET macOS prototype uses an explicit local Python PQ primitive provider. SDKs do not supply your organization’s identity verification, approval interface, secure key custody or production storage. Read compatibility and limitations.
