  title: Solana Page an Address's Transaction History
  summary: List an address's recent transaction signatures and expand the newest one into full detail.
  description: >-
    The read path behind every Solana block explorer and wallet activity feed.
    The workflow lists confirmed signatures for an address backwards in time
    from the most recent confirmed block, then expands the newest signature into
    a fully parsed transaction with its fee, balance deltas, and log messages.
    The signature list carries a `before` cursor, so the caller can page deeper
    by re-running the flow with the last signature of the previous page. Every
    step spells out its JSON-RPC request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
