cumulus-pallet-parachain-system is a base pallet for Cumulus-based parachains.

This pallet handles low-level details of being a parachain. Its responsibilities include:

  • ingestion of the parachain validation data;
  • ingestion and dispatch of incoming downward and lateral messages;
  • coordinating upgrades with the Relay Chain; and
  • communication of parachain outputs, such as sent messages, signaling an upgrade, etc.

Users must ensure that they register this pallet as an inherent provider.
