Project Background
The contracts implement upgradeable proxy patterns with administrative control for smart contract systems. This allows changing the logic (implementation) of a deployed contract while preserving the same storage and address. The solution ensures modularity, maintainability, and secure admin-controlled upgrades.
Main Contracts:
- Proxy – Base contract for delegating calls.
- UpgradeabilityProxy – Allows changing the implementation address.
- AdminUpgradeabilityProxy – Adds admin-only access for upgrades and management.
- AddressUtils – Utility to check if an address is a contract.
