Overview

Requests from your application are sent to an API gateway. This gateway authenticates requests and routes them to the relevant service. The primary services are bundlers and nodes, which communicate to each other in dedicated instances, and paymasters. A health monitor is used by the Stackup team to ensure reliability, and an Events Indexer captures on-chain events for faster retrieval.
