Overview

Envio is a modular hyper-performant data indexing solution for Base Sepolia, enabling applications and developers to efficiently index and aggregate real-time and historical blockchain data. Envio offers three primary solutions for indexing and accessing large amounts of data: HyperIndex (a customizable indexing framework), HyperSync (a real-time indexed data layer), and HyperRPC (extremely fast read-only RPC).

HyperSync accelerates the synchronization of historical data on Base Sepolia, enabling what usually takes hours to sync millions of events to be completed in under a minute—up to 1000x faster than traditional RPC methods.

Designed to optimize the user experience, Envio offers automatic code generation, flexible language support, multi-chain data aggregation, and a reliable, cost-effective hosted service.

To get started, see our documentation or follow our quickstart guide.
