+## Envio
+
+[Envio](https://envio.dev) is a full-featured data indexing solution that provides application developers with a seamless and efficient way to index and aggregate real-time and historical blockchain data for any EVM. The indexed data is easily accessible through custom GraphQL queries, providing developers with the flexibility and power to retrieve specific information. 
+
+Envio [HyperSync](https://docs.envio.dev/docs/hypersync) is an indexed layer of the Base blockchain for the hyper-speed syncing of historical data (JSON-RPC bypass). What would usually take hours to sync ~100,000 events can now be done in the order of less than a minute.
+
+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.
