+title: Envio
+---
+
+[Envio](https://envio.dev/) is a customizable, real-time indexing solution that provides developers with a seamless and efficient way to index and aggregate blockchain data. The indexed data is easily accessible through GraphQL queries, providing developers with the flexibility and power to retrieve specific information.
+
+Envio offers native support for Linea (both testnet and mainnet) and has been designed to support high-throughput blockchain applications that rely on real-time data for their business requirements.
+
+Designed to optimize the user experience, Envio offers automatic code generation, flexible language support, quickstart templates, and a reliable cost-effective hosted service.
+
+Indexers on Envio can be written in JavaScript, TypeScript, or ReScript.
+
+
+## Envio HyperSync 
+
+Envio offers support for [HyperSync](https://docs.envio.dev/docs/hypersync) on Linea mainnet. 
+
+HyperSync is an indexed layer of the Linea blockchain, providing accelerated APIs (JSON-RPC bypass) for the hyper-speed syncing of historic data. Developers do not need to worry about RPC URLs, rate-limited APIs, or managing infrastructure, and can easily sync large datasets in a few minutes, something that would usually take 20x longer via JSON-RPC.  
+
+
+## Other Features 
+
+- Fully customizable to meet your unique data needs. 
+
+- Aggregate data from multi-chain / cross-chain deployments into a unified GraphQL API (or REST API). 
+
+- Detailed logging and error messaging are provided for effective troubleshooting and debugging.
+
+- Quickstart templates with pre-defined indexing logic for popular OpenZeppelin contracts (ERC20, ERC721, ERC1155, etc.)
+
+## Getting Started
+
+The following files are required from the user to run the Envio indexer:
+
+- Configuration (defaults to `config.yaml`)
+- GraphQL Schema (defaults to `schema.graphql`)
+- Event Handlers (defaults to `src/EventHandlers.*` depending on the language chosen)
+
+These files are auto-generated according to the template and language chosen by running the `envio init` command.
+
+[**Quickstart Guide**](https://docs.envio.dev/docs/quickstart)
+
+
+```bash
+? Would you like to start from a template or migrate from a subgraph?
+> "Template"
+  "SubgraphMigration"
+[↑↓ to move, enter to select, type to filter]
+
+```
+
+Then choose a template out of the possible options
+
+```bash
+? Which template would you like to use?
+> "Blank"
+  "Greeter"
+  "Erc20"
+[↑↓ to move, enter to select, type to filter]
+```
+
+Then choose a language from **Javascript**, **Typescript**, or **Rescript** to write the event handlers file.
+
+```bash
+? Which language would you like to use?
+> "Javascript"
+  "Typescript"
+  "Rescript"
+[↑↓ to move, enter to select, type to filter]
+```
+
+This will create the config, schema and event handlers files according to the template and language chosen.
+
