HyperIndex: Fast Multichain Indexer
HyperIndex is a blazing-fast, developer-friendly multichain indexer, optimized for both local development and reliable hosted deployment. It empowers developers to effortlessly build robust backends for blockchain applications.
HyperIndex is Envio's full-featured blockchain indexing framework that transforms on-chain events into structured, queryable databases with GraphQL APIs.
HyperSync is the high-performance data engine that powers HyperIndex. It provides the raw blockchain data access layer, delivering up to 2000x faster performance than traditional RPC endpoints.
While HyperIndex gives you a complete indexing solution with schema management and event handling, HyperSync can be used directly for custom data pipelines and specialized applications.

HyperSync API Token Requirements
HyperSync (the data engine powering HyperIndex) implements rate limits for requests without API tokens. API tokens will be required from 3 November 2025. Here's what you need to know:
- Local Development: An API token will be required. An automatic login feature from the CLI will be available to make this smoother.
- Self-Hosted Deployments: API tokens are required for HyperSync access in self-hosted deployments. The token can be set via the
ENVIO_API_TOKENenvironment variable in your indexer configuration. This can be read from the.envfile in the root of your HyperIndex project. - Hosted Service: Indexers deployed to our hosted service will have special access that doesn't require a custom API token.
- Future Pricing: From mid-November 2025 onwards, we will introduce tiered packages for those self-hosting hyperindex and wishing to use hypersync. For preferred introductory pricing based on your specific use case, reach out to us on Discord.
For more details about API tokens, including how to generate and implement them, see our API Tokens documentation.
Feature Roadmap
