DOS Chain

Indexing DOS Chain Data with Envio via RPC​

warning

RPC as a source is not as fast as HyperSync. It is important in production to source RPC data from reliable sources. We recommend our partners at drpc.org. Below, we have provided a set of free endpoints sourced from chainlist.org. We don't recommend using these in production as they may be rate limited. We recommend tweaking the RPC config to accommodate potential rate limiting.

We suggest getting the latest from chainlist.org.

Overview​

Envio supports DOS Chain through an RPC-based indexing approach. This method allows you to ingest blockchain data via an RPC endpoint by setting the RPC configuration.

Defining Network Configurations​

To use DOS Chain, define the RPC configuration in your network configuration file as follows:

info

You may need to adjust more parameters of the rpc configuration to support the specific rpc provider.

name: IndexerName # Specify indexer name
description: Indexer Description # Include indexer description
networks:
  - id: 7979 # DOS Chain
    rpc_config:
      url: https://main.doschain.com 
    start_block: START_BLOCK_NUMBER # Specify the starting block
    contracts:
      - name: ContractName
        address:
          - "0xYourContractAddress1"
          - "0xYourContractAddress2"
        handler: ./src/EventHandlers.ts
        events:
          - event: Event # Specify event
          - event: Event
