Developer's guide overview

The Substreams Developer's guide explains the process of building a Substreams module responsible for tracking the ERC721 holder count for an Ethereum smart contract.
Tip: The Substreams Developer's guide is focused on an Ethereum Substreams module. The development tasks and workflow are independent of the blockchain selected for your project.
Example Substreams modules for Solana, Aptos, and other chains are available for reference and study. Find a full list on the examples page of the Substreams documentation.
Read through the fundamentals and modules overview to create a solid foundation of knowledge for Substreams development.
