Core contracts
Protocol contracts for hierarchical subnet communication and state management.
The core contracts manage subnet creation, bridging, validator entrance, and all activities related to the core maintaining consensus over state (checkpointing, etc).
Gateway
The Gateway is a core component that handles cross-subnet communication and message passing between parent and child subnets in the IPC hierarchy. It manages the transfer of funds and messages between subnets through checkpointing mechanisms. For example, when you deposit or withdraw RECALL, the gateway is responsible for ensuring both the parent and child subnet states are in sync.
Registry
The Registry maintains the record of all subnets in the IPC hierarchy. It helps track subnet relationships and configurations and works alongside the Gateway to enable proper routing and validation of cross-subnet communications.
Supply source
The supply source for a subnet provides funds that get deposited (bridged) from the parent chain into the subnet, and withdrawals are supported as well.
Validator gater
The Validator Gater controls actions like staking, unstaking, validator membership adjustments, and validator power assignments.
Validator rewarder
The Validator Rewarder contract handles the distribution of rewards to subnet validators.
Subnet actor
The Subnet Actor manages subnet operations including: validator set management, collateral handling, checkpointing, cross-subnet message processing, and configuration management. It acts as the main control point for subnet functionality and governance.
When you see a subnet string ID values (e.g., r314159/t410...), the t410... part is the contract
address of the subnet actor but given as its
low-level actor ID representation.
