  title: Kraken Fund the Futures Wallet from Spot
  summary: Check spot balance, transfer to the futures wallet, then confirm it landed.
  description: >-
    A cross-product funding flow spanning the Kraken Spot and Futures REST APIs.
    It reads the spot account balance, transfers an asset from the Spot wallet to
    the Futures wallet, and reads the futures accounts to confirm the funds
    arrived. Because the WalletTransfer call lives in the Spot description and the
    confirming Accounts call lives in the Futures description, both sources are
    referenced. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
