Introduction

About Hemera Indexer

As the foundation of the Hemera Protocol, the blockchain indexer plays a crucial role. It is the primary component that enables efficient and organized access to blockchain data.

Initially inspired by open-source projects like Ethereum ETL, we expanded its capabilities as the Ethereum ecosystem evolved, with the emergence of more Layer 2 chains and new ERC standards. Recognizing the need for a robust solution, we decided to develop our own indexer as the first step in building the Hemera Protocol Network.

As of July 5, 2024, the initial open-source version of the Hemera Indexer offers comprehensive functionality, allowing for the indexing of any EVM-compatible chains and providing all necessary data for a basic blockchain explorer. In the coming weeks, we plan to incorporate additional features from our in-house version into the open-source version.
