This factory dynamically registers offering implementations and deploys minimal proxy clones.

State Variables

offeringImplementations

mapping(bytes32 => OfferingImplementation) public offeringImplementations;

allOfferings

address[] public allOfferings;

Functions

constructor

Registers initial offering implementations.

constructor(OfferingImplementation[] memory _implementations);

Parameters

Name	Type	Description
_implementations	OfferingImplementation[]	Array of offering implementations to register.

addOfferingImplementation

Adds a new offering implementation dynamically.

function addOfferingImplementation(OfferingImplementation memory _implementation) external;

Parameters

Name	Type	Description
_implementation	OfferingImplementation	The offering implementation details.

createOffering

Deploys a new offering clone using a minimal proxy and initializes it.

function createOffering(bytes32 offeringImplId, bytes calldata initCallData) external returns (address offering);

Parameters

Name	Type	Description
offeringImplId	bytes32	The identifier of the offering implementation.
initCallData	bytes	The initialization call data to configure the offering clone.

Returns

Name	Type	Description
offering	address	The address of the newly deployed offering clone.

getAllOfferings

Returns an array of all deployed offering clone addresses.

function getAllOfferings() external view returns (address[] memory);

_getRevertMsg

Structs

OfferingImplementation

Struct for storing offering implementation details.
