Core Contracts
PID
PID
is the core NFT contract that represents Payment ID ownership as ERC-721 tokens. It handles token registration, transfers, and delegates ownership and resolver management to the PIDRegistry contract. This contract implements the tokenized representation of Payment IDs, allowing them to be transferred, approved, and managed like standard NFTs.
PIDRegistry

RegistrationController

is a contract that manages the registration process for Payment ID tokens. The contract allows users to register new Payment IDs and configure their address records across different source types and chains. It enforces registration rules and ensures proper initialization of associated resolver records.
