IssuersModule

Description of the official SchemaModule contract. This module aims to provide a standard way of checking if the subject of an Attestation payload is an Issuer.

When to use this module?

An Issuer might want to restrict his portal to only Issuers. In other words, his portal will only be able to attest Issuers as subjects (entities being attested) of the future attestations.

Once this module is set for a portal, any attestation request going through the portal will need to be destined to an Issuer as a subject.

The list of Issuers changes over time, but is not controlled by this module. It is managed at the PortalRegistry level.

When not to use this module?

This Module probably serves its purpose in only a few cases, so make sure your use case requires to only issue attestations to Issuers.

How to use this module?

This Module doesn't require any preliminary setup, you need to pass its address registering your Portal.
