API Gateways

API Gateways act as the intermediary layer between external requests and internal services, managing traffic and security for decentralized applications. They are often the first point of contact for an application attempting to reach a service endpoint discovered via a DID.

In financial systems, the gateway handles rate limiting, authentication, and request routing to ensure that the backend services remain stable. By using API gateways in conjunction with DIDs, protocols can expose secure, authenticated endpoints for trading or data retrieval.

This setup is vital for scaling decentralized services and ensuring that only authorized parties can access critical market infrastructure. It adds a layer of professional management to the raw, peer-to-peer nature of blockchain interactions.
