This is a smart contract upgrade manager for Ethereum projects using Hardhat, designed to manage and upgrade contracts through a central UpgradeManager contract. It supports OpenZeppelin transparent upgradeable proxies and abstract contracts, with tooling for M-of-N Gnosis Safe ownership and atomic upgrades/configuration changes. The system allows developers to propose changes while requiring safe owner approval, making it suitable for teams developing and maintaining smart contract systems on Ethereum.
