DXconfig

Overview

DXconfig is the configuration management and access control contract for the InkDAO platform. It maintains role-based permissions and stores critical protocol parameters in a centralized, upgradeable manner. The contract acts as a registry for both addresses and numeric values used across the platform.

Contract Details

  • Type: Upgradeable (Initializable)

  • Inherits: AccessControlUpgradeable

  • Role Management: Uses OpenZeppelin's AccessControl

  • Solidity Version: ^0.8.20

Key Responsibilities

  1. Registry: Store contract addresses for MarketPlace and other contracts

  2. Parameters: Store protocol configuration values (fees, limits)

  3. Access Control: Manage admin roles and permissions

  4. Lookup Service: Provide configuration access to other contracts

Roles

DEFAULT_ADMIN_ROLE (0x0)

The admin role has full control over the platform:

Privileges:

  • Grant and revoke roles

  • Update contract addresses

  • Update protocol parameters

  • Pause/unpause contracts

Security Considerations

  • Centralized configuration requires trust in admin

  • Admin can update critical parameters

  • Role management follows OpenZeppelin best practices

  • Zero address checks on initialization

  • Immutable after initialization (upgradeable pattern)

  • Key validation prevents accidental overwrites
