DatasetFactory Code Style Findings

DFY-01C: Inefficient Contract Imports

Type	Severity	Location
Gas Optimization		DatasetFactory.sol:L6-L8

Description:

The DatasetFactory contract will contain an inflated bytecode size as it imports the full VerifierManager, DistributionManager, and ERC20SubscriptionManager implementations even though they are solely utilized as interface declarations.

Example:

Copy
6import {VerifierManager} from "./verifier/VerifierManager.sol";
7import {DistributionManager} from "./distribution/DistributionManager.sol";
8import {ERC20SubscriptionManager} from "./subscription/ERC20SubscriptionManager.sol";

Recommendation:

We advise a proper interface to be coded for each contract (i.e. IVerifierManager) and to be imported to the DatasetFactory, minimizing its deployed bytecode size.

Alleviation (fb50b5c39665f7df086b2de1fdbf93ba2d836bf9):

All referenced contract implementation import statements have been replaced by their newly introduced I prefixed interface declarations, optimizing the bytecode size of the contract significantly.
