ADeployerGuard

Overview​

License: MIT​

abstract contract ADeployerGuard

A utility contract that provides protected initialization capabilities for other contracts.

Generally speaking, the common "Initializer" approach is easily front-runnable and shouldn't be used on its own.

This simple utility ensures that contracts are never left in an unprotected state during deployment by integrating a second validation step restricted to the deployer only.

Usage example:​

contract ProtectedERC20 is ADeployerGuard, ERC20 {
    constructor() ADeployerGuard(msg.sender) {}

    function __ProtectedERC20_init(
        string memory name_,
        string memory symbol_,
    ) external initializer onlyDeployer {
        __ERC20_init(name_, symbol_);
    }

    ...
}
