  OpenZeppelin Defender offered three subscription tiers for its hosted security
  platform. New sign-ups were disabled on June 30, 2025, and Defender will shut
  down on July 1, 2026. Users are migrating to the open-source OpenZeppelin Relayer
  and OpenZeppelin Monitor projects, which are self-hosted and free to use.
  The open-source projects have no subscription tiers — operators self-host and
  bear their own infrastructure costs.
