What problem does it solve?

Writing and maintaining event handlers for the Polymarket indexer can be error-prone without a consistent syntax and a reliable context API. This section explains how to standardize handler registration, access event data, and perform common tasks safely.

Core Features & Use Cases

  • Handler Registration: Register contract events with a clear API that exposes event, context, and chain information.
  • Context API: Read and write entities, perform queries, and access runtime information like chainId, isLive, context.log.
  • Safe Updates: Use spread updates to ensure immutability while applying changes to entities.
  • Runtime Interactions: Leverage indexer runtime API to introspect contracts, chains, and handlers during development.
  • Common Pitfalls: Avoid undefined fields, misusing _id suffixes, and unsafe mutations.

Quick Start

Create a new handler using Contract.Event.handler and start the indexer, then validate runtime execution in a test environment.
