Envio

Envio is a customizable, real-time indexing solution that provides developers with a seamless, efficient way to index and aggregate blockchain data. The indexed data is accessible through GraphQL queries, providing developers with the ability to flexibly 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 on Linea Mainnet.

HyperSync is an indexed layer of the Linea blockchain, providing accelerated APIs (JSON-RPC bypass) for fast historical data syncing. Developers do not need to worry about RPC URLs, rate-limited APIs, or managing infrastructure, and can 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 for effective troubleshooting and debugging.
  • Quickstart templates with pre-defined indexing logic for popular OpenZeppelin contracts (ERC-20, ERC-721, ERC-1155, etc.)

Get 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.

See our quickstart guide.

? Would you like to start from a template or migrate from a subgraph?
> "Template"
  "SubgraphMigration"

Then choose a template out of the possible options:

? Which template would you like to use?
> "Blank"
  "Greeter"
  "ERC-20"
[↑↓ to move, enter to select, type to filter]

Then choose a language from Javascript, Typescript, or Rescript to write the event handlers file.

? 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.
