Chains Screen

Chains Screen

Purpose

  • Configures blockchain connections for indexing and monitoring
  • Ensures proper RPC endpoint setup for each chain
  • Explains the requirement for Ethereum mainnet

Key Features

  • Multiple chain support with standardized naming
  • RPC endpoint configuration and validation
  • Clear explanation of requirements and format

Chain Configuration

The chains configuration screen guides you through setting up:

  1. Ethereum Mainnet (Required)

    • At least one valid RPC endpoint
    • Used for core functionality and the Unchained Index

  2. Additional EVM Chains (Optional)

    • Sepolia, Gnosis, Optimism, and other EVM-compatible chains
    • Each requires at least one RPC endpoint
    • Enable/disable option for each chain

RPC Endpoint Requirements

For each chain, you must provide:

  • A valid RPC URL in the format protocol://host:port
  • Proper authentication details if required (e.g., Infura project ID)
  • Endpoints with sufficient capabilities for indexing (archive nodes recommended)

Validation Checks

The wizard performs these validations on each RPC endpoint:

  • URL format validation
  • Connection test to verify the endpoint is reachable
  • Chain ID verification to ensure the endpoint matches the selected chain
  • API method support check for required JSON-RPC methods
