• 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 SRC20 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 SRC1155)
• MinimalisticSRC1155WithSRC20FractionsDataManager - DataManager implements token with fungible fractions with SRC1155 interface, linked to a DataManager which implements SRC20 interface for same token
