Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an\n external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer\n function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.\n The initialization functions use a version number. Once a version number is used, it is consumed and cannot be\n reused. This mechanism prevents re-execution of each \"step\" but allows the creation of new initialization steps in\n case an upgrade adds a module that needs to be initialized.\n For example:\n [.hljs-theme-light.nopadding]\n ```\n contract MyToken is ERC20Upgradeable {\n function initialize() initializer public {\n __ERC20_init(\"MyToken\", \"MTK\");\n }\n }\n contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {\n function initializeV2() reinitializer(2) public {\n __ERC20Permit_init(\"MyToken\");\n }\n }\n ```\n TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as\n possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.\n CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure\n that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.\n [CAUTION]\n ====\n Avoid leaving a contract uninitialized.\n An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation\n contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke\n the {_disableInitializers} function in the constructor to automatically lock it when it is deployed:\n [.hljs-theme-light.nopadding]\n ```\n /// @custom:oz-upgrades-unsafe-allow constructor\n constructor() {\n _disableInitializers();\n }\n ```\n ====" }, "fullyImplemented": true, "id": 23690,
