  title: Ankr Wallet Portfolio Snapshot
  summary: Read a wallet's token balances and then its recent ERC-20 transfer history.
  description: >-
    Builds a portfolio snapshot for a wallet by first pulling its native and
    ERC-20 balances across the supplied chains with ankr_getAccountBalance, then
    pulling the wallet's recent ERC-20 transfer history with ankr_getTokenTransfers
    so a caller can see both current holdings and the movements that produced them.
    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.
