HyperIndex

HyperIndex is Envio's blockchain indexing framework. Developers list the contracts and events they want in a config file, describe their data model in a GraphQL schema, and write event handlers in TypeScript, JavaScript, or ReScript. HyperIndex stores the results in Postgres and serves them through a GraphQL API.

It reads historical and live data through HyperSync, which returns filtered blocks, logs, and transactions much faster than standard RPC. Chains without HyperSync support can be indexed over RPC instead.

One indexer can cover several chains at once. HyperIndex handles reorgs, factory contracts that deploy new contracts at runtime, wildcard indexing by event topic, and calls to external data through its Effect API. The CLI can also generate a starter indexer from a contract address. Indexers run locally with Docker, on your own infrastructure, or on Envio Cloud, Envio's managed hosting.

Beyond the chains shown here, HyperIndex supports any EVM chain, plus Solana and Fuel. The full list is at docs.envio.dev/docs/HyperIndex/supported-networks.
