approval-indexer

Use when indexing contracts deployed by factory contracts at runtime. contractRegister API, dynamic contract config (no address), async registration, and same-block event coverage.

Use when writing or editing event handlers. Handler registration, context API (entity CRUD, getWhere queries, chain, log), spread updates, indexer runtime API, and common pitfalls.

Use when deploying an indexer across multiple chains. Entity ID namespacing to avoid collisions, chain-specific configuration patterns, and the context.chain runtime API.

Use when needing transaction-level data in handlers. Configure field_selection to include transaction fields on events, and access via event.transaction. No native transaction handler — access through event handlers.
