IProtectedHoldByPartition
Asset Tokenization Studio Team
IProtectedHoldByPartition
Interface for the protected variant of partition-scoped hold creation, gated by a per-partition role and an off-chain signature provided by the token holder.
Inherits the shared IHoldTypes module so the ProtectedHold struct and the ProtectedHeldByPartition event are referenced from a single source of truth and never redeclared. This interface is aggregated into the IAsset umbrella; the facet itself never inherits the umbrella.
Methods
initializeProtectedHoldByPartition
function initializeProtectedHoldByPartition() external nonpayable
Initialises the protected-hold-by-partition capability on the token.
Callable once; subsequent calls revert with FacetAlreadyRegistered. Requires DEFAULT_ADMIN_ROLE. Called by the factory during deployment.
protectedCreateHoldByPartition
function protectedCreateHoldByPartition(bytes32 _partition, address _from, IHoldTypes.ProtectedHold _protectedHold, bytes _signature) external nonpayable returns (bool success_, uint256 holdId_)
