Why Indexers Matter

Blockchains like Neutron are optimized for consensus and security, not for complex queries. Indexers solve this problem by:
  1. Extracting data from the blockchain into optimized databases
  2. Enabling complex queries that would be impossible or too slow on-chain
  3. Supporting real-time data feeds for applications
  4. Reducing load on blockchain nodes
For building indexers for Neutron, we recommend:
  • SubQuery: A flexible indexing solution for Cosmos chains
  • PostgreSQL: For storing indexed data
  • GraphQL: For querying indexed data
  • Docker: For containerizing your indexer

​
Prerequisites

Before diving into the indexer development tutorials, you should:
  1. Have a basic understanding of databases and SQL
  2. Be familiar with Neutron’s data structures and event system
  3. Have experience with at least one programming language (typically JavaScript/TypeScript or Go)
  4. Understand the basics of GraphQL (for some indexers)
