  title: Ankr Chain Overview
  summary: Read a chain's aggregate stats, then its supported currency catalog.
  description: >-
    Builds an at-a-glance overview of a blockchain by reading aggregate chain
    statistics with ankr_getBlockchainStats and then the catalog of supported
    currencies for the same chain with ankr_getCurrencies. Each step is written
    out inline as a JSON-RPC call so the flow can be read and executed without
    opening the underlying OpenAPI description.
