Indexer Guides

A blockchain indexer, such as The Graph or SubQuery, plays a crucial role in enabling efficient and reliable data retrieval from blockchain networks. By maintaining a comprehensive index of blockchain data, these indexers enable developers to build applications and services that interact with the blockchain more efficiently. Instead of querying the entire blockchain for specific data, developers can rely on the index to quickly retrieve the information they need. In this tutorial, we'll walk through a few populated indexers.
