  title: Backpack Get Deposit Address and Reconcile History
  summary: Fetch a blockchain deposit address, then read deposit history to reconcile incoming funds.
  description: >-
    A funding flow for the Backpack Exchange. It retrieves the account-specific
    deposit address for a given blockchain and then reads recent deposit history
    so the caller can reconcile an expected incoming deposit against what the
    exchange has recorded. Both steps inline their request — including the
    ED25519 signing headers required on authenticated calls — so the flow can be
    read and executed without opening the underlying OpenAPI description.
