# Overview

The issuer, similar to other services in the Enterprise Stack, maintains a collection of configurations. These
configurations include **internal configs such as signing keys for access tokens and the base URL**, which are used solely
within the Enterprise Stack. Additionally, the issuer holds configurations that is both internally used and **externally
shared, such as supported credential types and issuer display information**. This external information is made available
through the **OpenID issuer metadata endpoint**, which can be accessed by wallets and other external applications involved
in the credential exchange process.
