Overview​

Envio is a modular hyper-performant data indexing solution for Katana, 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 Katana, enabling what usually takes hours to sync millions of events to be completed in under a minute—up to 2000x 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.

Defining Chain Configurations​

description: Indexer Description # Include indexer description
chains:
  - id: 747474 # Katana
    start_block: START_BLOCK_NUMBER  # Specify the starting block
    contracts:
      - name: ContractName
        address:
          - "0xYourContractAddress1"
          - "0xYourContractAddress2"
        events:
          - event: Event # Specify event
          - event: Event

With these steps completed, your application will be set to efficiently index Katana data using Envio’s blockchain indexer.
