overview: >-
  The Mesh sandbox is a full replica of production — same API, same flows, same SDK —
  using simulated exchange accounts and real blockchain testnets so integrations can be
  built and tested without touching real funds. Sandbox API keys are separate from
  production keys and managed in the same dashboard section.
