Reference implementation of ERC-7208 and usage examples

List of contracts

Interfaces

• IDataIndex - Interface of DataIndex
• IDataObject - Interface of DataObject
• IDataPointRegistry - Interface of Data Point Registry
• IIDManager - Interface for building and querying Data Index user identifiers

Implementation

• DataIndex - Data Index (implements IDataIndex and IIDManager)
• DataPointRegistry - Data Point Registry (implements IDataPointRegistry)
• DataPoints - Library implementing DataPoint type and its encode/decode functions
• ChainidTools - Library implementing utility functions to work with chain ids

Usage examples

• IFractionTransferEventEmitter - Interface used for DataManagers communication to emit ERC20 Transfer events
• IFungibleFractionsOperations - Interface defines DataObject operations, which can be called by DataManager
• MinimalisticFungibleFractionsDO - DataObject implements data storage and related logic for token with Fungible Fractions (like ERC1155)
• MinimalisticERC1155WithERC20FractionsDataManager - DataManager implements token with fungible fractions with ERC1155 interface, linked to a DataManager which implements ERC20 interface for same token
• MinimalisticERC20FractionDataManager - implements token with ERC20 interface, linked to a DataManager which implements ERC1155 interface for same token
• MinimalisticERC20FractionDataManagerFactory - factory of DataManagers implementing ERC20 interface for token with fungible fractions
