  title: Solana Snapshot Network Supply and Staking Economics
  summary: Read total and circulating supply, profile the largest accounts, and read inflation and staking floors.
  description: >-
    The macro read behind economics dashboards and research reports. The
    workflow reads the network's total, circulating, and non-circulating
    lamport supply, profiles the twenty largest circulating accounts to show how
    concentrated that supply is, reads the inflation governor's long-run
    parameters and the inflation rate actually in force this epoch, and reads
    the minimum lamports a stake account must delegate. getLargestAccounts
    results may be cached by the node for up to two hours. Every step spells out
    its JSON-RPC request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.

        type: boolean
        description: >-
          Set true to omit the non-circulating account list from the supply
          response, which makes the payload far smaller.
        default: false
  steps:
  - stepId: supply
    description: >-
      Read the current supply of lamports across the network, split into
      circulating and non-circulating.

  - stepId: largestCirculatingAccounts
    description: >-
      Profile the twenty largest accounts by lamport balance, filtered to
